This paper aims to investigate the temporal content of perceptual experience. It argues that we must recognize the existence of temporal perceptions, i.e., perceptions the content of which cannot be spelled out simply by looking at what is the case at an isolated instant. Acts of apprehension can cover a succession of events. However, a subject who has such perceptions can fall short of having a concept of time. Similar arguments have been put forward to show that a subject (...) who has spatial perceptions can fall short of having a concept of space. In both cases, it is the fact that perception is from a point of view which stands in the way of it constituting an exercise of a concept of how things are objectively. However, the paper also shows that the way in which perception is perspectival takes a different form in each of the two cases. (shrink)

In this paper, I offer an account of the dependence relation between perception of change and the subjective flow of time that is consistent with some extant empirical evidence from priming by unconscious change. This view is inspired by the one offered by William James, but it is articulated in the framework of contemporary functionalist accounts of mental qualities and higher-order theories of consciousness. An additional advantage of this account of the relationship between perception of change and (...) subjective time is that is makes sense of instances where we are not consciously aware of changes but still experience the flow of time.

Aristotle recognizes two modes of apprehending time, viz., perceiving time and grasping time intellectually. This chapter clarifies what is and is not involved in these two modes of apprehending time. It also clarifies the way in which they interact, and argues that, according to Aristotle, one’s intellectual grasp of time has an effect on one’s perception of time for those beings who have intellect.

We present a rigorous way to evaluate the visual perception of correlation in scatterplots, based on classical psychophysical methods originally developed for simple properties such as brightness. Although scatterplots are graphically complex, the quantity they convey is relatively simple. As such, it may be possible to assess the perception of correlation in a similar way. Scatterplots were each of 5.0 extent, containing 100 points with a bivariate normal distribution. Means were 0.5 of the range of the points, and (...) standard deviations 0.2 of this range. Precision was determined via an adaptive algorithm to find the just noticeable differences (jnds) in correlation, i.e., the difference between two side-by-side scatterplots that could be discriminated 75% of the time. Accuracy was measured by direct estimation, using reference scatterplots with fixed upper and lower values, with a test scatterplot adjusted so that its correlation appeared to be halfway between these. This process was recursively applied to yield several further estimates. Results of the discrimination tests show jnd(r) = k (1/b – r), where r is the Pearson correlation, and parameters 0 < k, b < 1. Integration yields a subjective estimate of correlation g(r) = ln(1 – br) / ln(1– b). The values of b found via discrimination closely match those found via direct estimation. As such, it appears that the perception of correlation in a scatterplot is completely described by two related performance curves, specified by two easily-measured parameters. (shrink)

This study was conducted to find out head teachers' perception of the implementation of the capitation grant scheme in Sunyani West East District of the Brong Ahafo Region. The study specifically focused on explaining how head teachers conceptualised the concept of capitation grant scheme, the implementation process, and the challenges associated with the implementation of the scheme. A descriptive research design was adopted for the study, and a questionnaire and an interview guide were designed and administered to a sample (...) of 40 head teachers from the district in the Region. The analysis of data revealed that 70.0% of the head teachers had an in-depth understanding of the source of capitation grant as being from the Government. The study, among others, found that the main challenges confronting the smooth implementations of the scheme were delay in the release of funds and inadequate funds. It is recommended that Government should release adequate amount of the grant in good time (thus, before the beginning of each quarter) so that school heads will avoid pre-financing of school activities. Also, the Ghana Education Service should continue to train head teachers in financial management and administration for prudent use of funds. (shrink)

I consider what draws us to perceiving beautiful bodies in art and athletics--repeatedly and over time--that is informed by viewers' changing perceptions derived from recent publications in fashion and sport, the philosophy of sport, feminist film theory and aesthetics under the ever-expanding umbrella of somaesthetics. This paper won the American Society for Aesthetics 2023 Somaesthetics Prize.

This paper explores the ethical insights provided by Anne Truitt's minimalist sculptures, as viewed through the phenomenological lenses of Hannah Arendt's investigations into the co-constitution of reality and Maurice Merleau-Ponty's investigations into perception. Artworks in their material presence can lay out new ways of relating and perceiving. Truitt's works accomplish this task by revealing the interactive motion of our embodied relations and how material objects can actually help to ground our reality and hence human potentiality. Merleau-Ponty shows how our (...) prereflective bodies allow incompossible perceptions to coexist. Yet this same capacity of bodies to gather multiple perceptions together also lends itself to the illusion that we see from only one perspective. If an ethical perspective becomes reified into one position, it then becomes detached from reality, and the ethical potential is actually lost. At the same time, phenomenologically understood, the real world does not exist in terms of static matter, but is instead a web of contextual relations and meanings. An ethics that does not take embodied relations into account—that allows for only one perspective—ultimately loses its capacity for flexibility, and for being part of a common and shared reality.

It is widely assumed that time appears to be tensed, i.e. divided into a future, present and past, and transitory, i.e. involving some kind of ‘flow’ or ‘passage’ of times or events from the future into the present and away into the distant past. In this paper I provide some reasons to doubt that time appears to be tensed and transitory, or at least that philosophers who have suggested that time appears to be that way have included (...) in ‘appearance’ everything that falls under the broad term ‘cognition’, i.e. mental processes of all kinds, including perceiving, remembering, imagining, and thinking. I argue that the tensed and transitory aspect of our experience of temporal reality is, firstly, subordinate to our experience of a world of persistent objects, secondly, in conflict with a popular conception of the nature of persistent material objects, and finally, that it is an aspect of how we think about temporal reality rather than how we actually experience it. I support the last contention by a comparison with our experience of spatiality, which arguably has three distinguishable components: (i) ‘pure input perception’, (ii) ‘perceptual experience modulated by top down cognitive processes’, and (iii) a ‘pure representation of space’. For space, the modulation of our perception of space at any given moment is highly influenced by our pure representation of space, but it is not clear to me that our modulated experience of space is influenced by a pure representation of time. Rather, the modulated experience of temporality, to my mind, is much more clearly an experience of continuous existence of the persisting objects that make up the world. (shrink)

J. McTaggart argues that the philosophical conception of time is constituted by the notions of fluid and static time. Since, on his view, neither notion is philosophically viable, he concludes that time is nothing but an illusion that arises from our distorted perception of essentially atemporal reality. In the paper, I argue that despite McTaggart’s failure to prove the unreality of time as such, he does succeed in establishing his lesser claim that the concept of (...) fluid time is without any ontological import whatsoever.

This study discusses foreign tourists' perceptions of Toraja which is a cultural tourism site in South Sulawesi, Indonesia. Every year, tourists visit Toraja to participate in their yearly rituals of death take time to visit the graves inside the mountain cliffs (in caves) as they feel the rich cultural heritage and have a view of the traditional houses. Data were collected by interviewing these tourists through the use of questionnaires with randomly selected respondents. The results obtained showed that knowledge (...) about Toraja cultural tourism gained by foreign tourists before their visit creates curiosity and willingness to obtain experiences in Toraja ethnic culture. Foreign tourists get to experience Toraja's rich cultural heritage. According to them, Toraja is one of the most unique, special and outstanding tourism centers in the world. The uniqueness of Toraja culture creates greater curiosity among tourists so that they want to have a cultural experience by conducting a tour to Toraja and through direct communication with Toraja people. However, they also stated the importance of some objects other than those previously listed. Tourist objects that are all related to grief such as graves, however, cause some boredom. Some tourists frowned upon the mismanagement of some tourist centers such as the natural agrotourism center which is known to produce the ingredients used in Toraja products and they suggested ways to manage these areas more effectively.

Does time seem to pass, even though it doesn’t, really? Many philosophers think the answer is ‘Yes’—at least when ‘time’s passing’ is understood in a particular way. They take time’s passing to be a process by which each time in turn acquires a special status, such as the status of being the only time that exists, or being the only time that is present. This chapter suggests that, on the contrary, all we perceive is (...) temporal succession, one thing after another, a notion to which modern physics is not inhospitable. The contents of perception are best described in terms of ‘before’ and ‘after’, rather than ‘past’, ‘present, and ‘future’. (shrink)

The Whorfian hypothesis has received support from recent findings in psychology, linguistics, and anthropology. This evidence has been interpreted as supporting the view that language modulates all stages of perception and cognition, in accordance with Whorf’s original proposal. In light of a much broader body of evidence on time perception, I propose to evaluate these findings with respect to their scope. When assessed collectively, the entire body of evidence on time perception shows that the Whorfian (...) hypothesis has a limited scope and that it does not affect early stages of time perception. In particular, all the available evidence shows that the scope of language modulation is limited in the case of time perception, and that the most important mechanisms for time perception are cognitive clocks and simultaneity windows, which we use to perceive the temporal properties of events. Language modulation has distorting effects, but only at later stages of processing or with respect to specific categorization tasks. The paper explains what is the role of these effects in the context of all the available evidence on time cognition and perception. (shrink)

There is an apparent tension in Shepherd’s accounts of space and time. Firstly, Shepherd explicitly claims that we know that the space and time of the unperceived world exist because they cause our phenomenal experience of them. Secondly, Shepherd emphasizes that empty space and time do not have the power to effect any change in the world. My proposal is that for Shepherd time has exactly one causal power: to provide for the continued existence of self-same (...) or changing objects. Because Shepherd takes causation to be a relation whereby two objects combine to form a third, their effect, whenever we perceive a continually existing object, since time is a proper part of such objects, our perception of time is caused by time itself. Likewise, space’s causal power is to provide for the possibility of the motion or rest of objects, and so when we perceive objects with space as a proper part, we come into causal contact with space.

Documentary film is that genre of filmmaking that lays bare the fact of all film, which is that it presents "a world past" (Cavell, The World Viewed). This fact of film seems to point to a paradox of time in our experience of movies: we are present at something that has happened, something that is over. But what if we were to take this fact to show that film has the power to place us outside our ordinary, unreflective relation (...) to time? In this essay I examine three pre-cinematic descriptions of relations to time – in Emerson, Thoreau, and Weil – that anticipate the paradox of time inherent in film. I then put that examination to use in a reading of Werner Herzog's Cave of Forgotten Dreams, a film ostensibly about prehistoric cave paintings but whose achievement is its declaration, not to document some past time, but to liberate the present moment.

Code-switching is explained as switching between two languages at the same time while conversing in the same discourse. The aim of this study is to explore the perceptions of Afghan EFL lecturers toward code- switching. This study used a qualitative research approach in which the data was collected via semi-structured interviews with five EFL lecturers. The lecturers were interviewed to explore their perceptions and reasons for code-switching, and the extent to which they practice code-switching in their classrooms. The results (...) revealed that the lecturers in the study had positive perceptions of code-switching and believed it as a beneficial strategy in facilitating the learning process. However, they also conveyed that an excessive practice of code-switching should be avoided. The study results also disclosed that the lecturers practiced code-switching for various functions such as explaining difficult concepts (translation), explaining complex grammatical points, clarifications, and giving instructions. Finally, the paper provides recommendation for further research. (shrink)

Sleep onset is associated with marked changes in behavioral, physiological, and subjective phenomena. In daily life though subjective experience is the main criterion in terms of which we identify it. But very few studies have focused on these experiences. This study seeks to identify the subjective variables that reflect sleep onset. Twenty young subjects took an afternoon nap in the laboratory while polysomnographic recordings were made. They were awakened four times in order to assess subjective experiences that correlate with the (...) (1) appearance of slow eye movement, (2) initiation of stage 1 sleep, (3) initiation of stage 2 sleep, and (4) 5 min after the start of stage 2 sleep. A logistic regression identified control over and logic of thought as the two variables that predict the perception of having fallen asleep. For sleep perception, these two variables accurately classified 91.7% of the cases; for the waking state, 84.1%. (shrink)

This chapter explores to what extent some core ideas of predictive processing can be applied to the phenomenology of time consciousness. The focus is on the experienced continuity of consciously perceived, temporally extended phenomena (such as enduring processes and successions of events). The main claim is that the hierarchy of representations posited by hierarchical predictive processing models can contribute to a deepened understanding of the continuity of consciousness. Computationally, such models show that sequences of events can be represented as (...) states of a hierarchy of dynamical systems. Phenomenologically, they suggest a more fine-grained analysis of the perceptual contents of the specious present, in terms of a hierarchy of temporal wholes. Visual perception of static scenes not only contains perceived objects and regions but also spatial gist; similarly, auditory perception of temporal sequences, such as melodies, involves not only perceiving individual notes but also slightly more abstract features (temporal gist), which have longer temporal durations (e.g., emotional character or rhythm). Further investigations into these elusive contents of conscious perception may be facilitated by findings regarding its neural underpinnings. Predictive processing models suggest that sensorimotor areas may influence these contents. (shrink)

Kant argued that the perceptual representations of space and time were templates for the perceived spatiotemporal ordering of objects, and common to all modalities. His idea is that these perceptual representations were specific to no modality, but prior to all—they are pre-modal, so to speak. In this paper, it is argued that active perception—purposeful interactive exploration of the environment by the senses—demands premodal representations of time and space.

Through the philosophies of Bergson and Deleuze, my paper explores a different theory of time. I reconstitute Deleuze’s paradoxes of the past in Difference and Repetition and Bergsonism to reveal a theory of time in which the relation between past and present is one of coexistence rather than succession. The theory of memory implied here is a non-representational one. To elaborate this theory, I ask: what is the role of the “virtual image” in Bergson’s Matter and Memory? Far (...) from representing the simple afterimage of a present perception, the “virtual image” carries multiple senses. Contracting the immediate past for the present, or expanding virtually to hold the whole of memory (and even the whole of the universe), the virtual image can form a bridge between the present and the non-representational past. This non-representational account of memory sheds light not only on the structure of time for Bergson, but also on his concepts of pure memory and virtuality. The rereading of memory also opens the way for Bergsonian intuition to play an intersubjective role; intuition becomes a means for navigating the resonances and dissonances that can be felt between different rhythms of becoming or planes of memory, which constitute different subjects.

Everyday media consumption leaves no doubt that the perception of moving images from various media is characterized by experience and understanding. Corresponding research in this field has shown that the stimulus patterns flooding in on us are not only processed mentally, but also bodily. Building on this, the following study argues that incoming stimuli are processed not only visually, but multimodally, with all senses, and moreover affectively. The classical binding of a sensory organ to a medium, on whose delimitation (...) the common understanding of multimodality is based, is thus abolished. Can arguments for this assumption be found? Building on the research of cultural anthropologist Ernst Cassirer and his successors, the two American philosophers Susanne K. Langer and John M. Krois, and supported by research from the life sciences in which, in parallel, the arts also play an important role in understanding image formation, as in the work of Heinz Werner and, following on from this, in the more recent research of the child psychologist Daniel N. Stern in collaboration with mirror neuron research by the group of neuroscientists around Giacomo Rizzolatti in Parma, justifications for this will be provided. What the multimodal processing of film images is concretely based on will finally be made clear by means of an exemplary analysis of a video film by the Swiss artist Pipilotti Rist. It aims to prove, that the prerequisites for the thesis can only lie in the fact, that both the modes of perception (visual, tactile, auditory, olfactory, gustatory) as well as the medially conditioned modes of image formation are based on non-discursive, formal-abstract structures that are also processed affectively. At the same time, the analysis thus shows how the selection and composition of the vital experienced forms can provide information about the socio-culturally shaped self-image of the producer and the viewer.

Our perceptual experience is largely based on prediction, and as such can be influenced by knowledge of forthcoming events. This susceptibility is commonly exploited by magicians. In the Vanishing Ball Illusion, for example, a magician tosses a ball in the air a few times and then pretends to throw the ball again, whilst secretly concealing it in his hand. Most people claim to see the ball moving upwards and then vanishing, even though it did not leave the magician’s hand (Kuhn (...) & Land, 2006; Triplett, 1900). But what exactly can such illusions tell us? We investigated here whether seeing a real action before the pretend one was necessary for the Vanishing Ball Illusion. Participants either saw a real action immediately before the fake one, or only a fake action. Nearly one third of participants experienced the illusion with the fake action alone, while seeing the real action beforehand enhanced this effect even further. Our results therefore suggest that perceptual experience relies both on long-term knowledge of what an action should look like, as well as exemplars from the immediate past. In addition, whilst there was a forward displacement of perceived location in perceptual experience, this was not found for oculomotor responses, consistent with the proposal that two separate systems are involved in visual perception.

Modes of teaching and learning have had to rapidly shift amid the COVID-19 pandemic. As an emergency response, students from Philippine public schools were provided learning modules based on a minimized list of essential learning competencies in Biology. Using a cross-sectional survey method, we investigated students’ perceptions of the Biology self-learning modules (BSLM) that were designed in print and digitized formats according to a constructivist learning approach. Senior high school STEM students from grades 11 (n = 117) and 12 (n (...) = 104) participated in a survey using a 3-point Likert-scale questionnaire uploaded online through Google Forms. The survey results indicate that majority of the students perceived the modules positively, suggesting that aspects of the modules that were salient to students corresponded to essential elements of constructivist pedagogies. However, during interviews, students reported several difficulties in learning with BSLM as it was constrained by, to name a few, the use of unfamiliar words, lack of access to supporting resources, slow internet connection, and time constraints. To address these problems, teachers reported that they gave deadline extensions, complemented modules with other channels of support, and used online and offline platforms for reaching out to students to answer their queries and plan out their schedule for the week. The findings across the data sources point to the complex demands of emergency distance education that teachers, as curriculum designers and enactors, need to bear in mind in order to craft productive pedagogies, constructivist or otherwise, during this unprecedented time.

It is common, even among the laity, the doubt about the reality of time. We think it is possible that time is an illusion and that the perception of his passage is just awareness of something other than time. There are a number of arguments made by philosophers, both to defend and to attack the intuition that time is real. One of them, and perhaps the best known, is the argument of McTaggart, which tries to (...) establish some condition for the existence of time and that time, thought through that condition and applied to reality, leads to a contradiction, which makes him conclude that time can not exist, and therefore does not exist. What I intend in this article is to present the argument of McTaggart along with some original and non-original objections, and try to show that if we accept the Prior’s approach of the flow of time, the cogency of the argument of McTaggart is lost.

A recently proposed model of sensory processing suggests that perceptual experience is updated in discrete steps. We show that the data advanced to support discrete perception are in fact compatible with a continuous account of perception. Physiological and psychophysical constraints, moreover, as well as our awake-primate imaging data, imply that human neuronal networks cannot support discrete updates of perceptual content at the maximal update rates consistent with phenomenology. A more comprehensive approach to understanding the physiology of perception (...) (and experience at large) is therefore called for, and we briefly outline our take on the problem. (shrink)

Traditional accounts of the perception/cognition divide tend to draw it in terms of subpersonal psychological processes, processes into which the subject has no first-person insight. Whatever betides such accounts, there seems to also be some first-personally accessible difference between perception and thought. At least in normal circumstances, naïve subjects can typically tell apart their perceptual states from their cognitive or intellectual ones. What are such subjects picking up on when they do so? This paper is an inconclusive search (...) for an answer. At its end, I conclude, without joy, that we may have to simply accept the perception/cognition distinction as a primitive and inexplicable bright line within the sphere of conscious phenomena.

In this paper, I study one aspect of the philosophical encounter between Spinoza and Hegel: the question of the reality of time. The precise reconstruction of the debate will require a close examination of Spinoza's concept of tempus (time) and duratio (duration), and Hegel's understanding of these notions. Following a presentation of Hegel's perception of Spinoza as a modern Eleatic, who denies the reality of time, change and plurality, I turn, in the second part, to look (...) closely at Spinoza's text and show that Hegel was wrong in reading Spinoza as denying the reality of duration and change. Ironically, Hegel's misreading of Spinoza as denying the reality of duration and change has been compensated for by a reading of Hegel as denying the reality of time by one of Hegel's most prominent followers, John Ellis McTaggart. I discuss McTaggart's reading of Hegel's Logic in the final part of the paper. (shrink)

The Special Theory of Relativity (STR) holds sway as a theory of time due to its apparently successful predictive structure regarding time-related phenomena such as the increased life spans of mesons or retarded clocks on jets circling the globe, and due to the relativization of simultaneity intrinsic to this theoretical structure. Yet the very structure of the theory demands that such very real physical effects be construed as non-ontological. The scope and depth of this contradiction is explored and, (...) if these time-changes are indeed viewed as ontological effects within STR, an additional problem for the theory is introduced in the context of perception. The origins of this confused situation arise as a result of the fact that STR is an expression of a classical, spatial metaphysic – a framework that equally underpins current discussions of the hard problem. This metaphysic holds an inadequate concept of time and a failure to acknowledge the reality of simultaneous causal flows. These problems are developed against the background of an alternative, namely, the temporal metaphysic of Bergson – a framework that provides a profoundly different base for viewing both relativity and consciousness.

In Taber's work, "A Hindu Critique of Buddhist Epistemology," Kumārila tackles the concept of perception in MS 1.1.4 and asserts that perception cannot serve as a means to comprehend Dharma. His argument revolves around the idea that perception apprehends objects in the present, while Dharma's outcomes lie in the future. This distinction holds significance because, according to Kumārila, only the Veda can be a valid means of understanding Dharma. However, I contend that the definition of perception (...) presented in MS 1.1.4 can be a viable method for comprehending Dharma. Kumārila defends the Veda's eternality, resulting in a unique Vedic concept of time that amalgamates past, present, and future into an ever-existing present. Given this perspective, when perception, as defined in MS 1.1.4, apprehends an object in the present, it extends the possibility of grasping the outcomes of Dharma in the future. This is possible because the Vedic conception of time posits an eternal continuum where past, present, and future coexist. Consequently, the proposed definition of perception in MS 1.1.4 can be a legitimate means of gaining knowledge about Dharma. (shrink)

This article argues that we can construct a complex interpretation of the nature of time by linking Aciman’s gnostic thread to aspects of twentieth century theory, from philosophy and psychoanalysis. In brief, it attempts to demonstrate the roles of dislocation, deferral, and Otherness in constituting human temporality. The essay begins by surmising the conceptual history of time, touching on key ideas put forward by Augustine and Bergson. The second section takes a psychoanalytic turn after exploring Homo Irrealis to (...) describe the significance of desire and fantasy. Thirdly, we develop a unique and temporal application of difference and deferral, building off of Deleuze and Derrida. The fourth section will consider how the psychoanalytic concept of the Other is inhered within time. We conclude that an Acimanic analysis of time is the means by which we can understand existence not as a series of moments, but a rich progression of dissimilitude and Otherness defined moreso by its lack of cohesion and directness of being than by a unified and self-identifying subject.

This paper investigates strategic planning to understand managers’ perception of its benefits to Non- Profit Organisations (NPOs). The investigation was preceded by a review and repertoire of theoretical evidence of NPOs integration of strategic planning in support of management function: a management tool designed for and used mainly by businesses. The study was based on the application of quantitative data collection and analysis to understand respondents’ perceptions. The paper found considerable increase and popularity in the usage of strategic planning (...) by NPOs having learned about its benefits from prior working experience in businesses. Even though, there is an increase in NPOs’ usage of strategic planning because of envisaged benefit, other NPOs’ Managers simply do not have enough time, skills and resources to deploy them in their respective NPOs. With limited and competitive funding, the use of strategic planning becomes competitive imperatives for NPOs seeking to attract the much-needed funds to support and promote their operations in South Africa.

It is often thought that there is little that seems more obvious from experience than that time objectively passes, and that time is, in this respect, quite unlike space. Yet nothing in the physical picture of the world seems to correspond to the idea of such an objective passage of time. In this paper, I discuss some attempts to explain this apparent conflict between appearance and reality. I argue that existing attempts to explain the conflict as the (...) result of a perceptual illusion fail, and that it is, in fact, the nature of memory, rather than perception, that explains why we are inclined to think of time as passing. I also offer a diagnosis as to why philosophers have sometimes been tempted to think that an objective passage of time seems to figure directly in perceptual experience, even though it does not.

The experiments reported herein probe the visual cortical mechanisms that control near–far percepts in response to two-dimensional stimuli. Figural contrast is found to be a principal factor for the emergence of percepts of near versus far in pictorial stimuli, especially when stimulus duration is brief. Pictorial factors such as interposition (Experiment 1) and partial occlusion Experiments 2 and 3) may cooperate, as generally predicted by cue combination models, or compete with contrast factors in the manner predicted by the FACADE model. (...) In particular, if the geometrical conŽ guration of an image favors activation of cortical bipole grouping cells, as at the top of a T-junction, then this advantage can cooperate with the contrast of the conŽ guration to facilitate a near–far percept at a lower contrast than at an X-junction. Varying the exposure duration of the stimuli shows that the more balanced bipole competition in the X-junction case takes longer exposure times to resolve than the bipole competition in the T-junction case (Experiment 3).

This book shows that in the naturalistic and Darwinian explanation of life and its evolution, a decisive factor is overlooked, namely the human, knowing mind. The questions about life and its evolution can be answered if consciousness is taken into account not as a spectator, but as an integral part of reality. In the first-person-perception of cognition, the forces and laws of organic development can be observed and explored. It becomes apparent that evolution was not a random event, but (...) the organic overall process of the becoming of man. (shrink)

Quality Space Theory is a holistic model of qualitative states. On this view, individual mental qualities are defined by their locations in a space of relations, which reflects a similar space of relations among perceptible properties. This paper offers an extension of Quality Space Theory to temporal perception. Unconscious segmentation of events, the involvement of early sensory areas, and asymmetries of dominance in multi-modal perception of time are presented as evidence for the view.

In this paper, we intend to promote an analysis of the use of the artificial language Heptapod B in Story of Your Life written by Ted Chiang and in its filmic adaptation, Arrival, written by Eric Heisserer and directed by Denis Villeneuve in relation to the authors’ views on the metaphysics of time. In both literary and filmic texts, the glossopoeia is used as a plot device upon which the alien race’s time perception is constructed and explicated (...) in connexion with the strong metaphor provided by Fermat’s principle of least time. Throughout the article, we discuss these hybrid interfaces of literature, cinema and science, researching the stories’ specific diegeses, the writers’ own elicitations as well as various texts on the Philosophy of time. The result consists of a comprehensive exegesis of the problematics generated by the narratives and an extensive philosophical debate on the subject. (shrink)

Is temporal representation constitutively necessary for perception? Tyler Burge (2010) argues that it is, in part because perception requires a form of memory sufficiently sophisticated as to require temporal representation. I critically discuss Burge’s argument, maintaining that it does not succeed. I conclude by reflecting on the consequences for the origins of temporal representation.

A recurring theme dominates recent philosophical debates about the nature of conscious perception: naïve realism’s opponents claim that the view is directly contradicted by empirical science. I argue that, despite their current popularity, empirical arguments against naïve realism are fundamentally flawed. The non-empirical premises needed to get from empirical scientific findings to substantive philosophical conclusions are ones the naïve realist is known to reject. Even granting the contentious premises, the empirical findings do not undermine the theory, given its overall (...) philosophical commitments. Thus, contemporary empirical research fails to supply any new argumentative force against naïve realism. I conclude that, as philosophers of mind, we would be better served spending a bit less time trying to wield empirical science as a cudgel against our opponents, and a bit more time working through the implications of each other’s views – something we can accomplish perfectly well from the comfort of our armchairs.

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, (...) and which ‘subjective’? What properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

I will use three simple arguments to refute the thesis that I appear to directly perceive a mind-independent material object. The theses I will use are similar to the time-gap argument and the argument from the relativity of perception. The visual object of imagination and the object of experience are in the same place. They also share common qualities such as the content, subjectivity, change in virtue of conditions of observers, and the like. This leads to the conclusion (...) that both a tree-image and a tree-experience are distinct from a material tree. Perception of an object is caused by human nature, the senses and consciousness, and mind may prevent the direct perception of the external world. The strongest objection against that consequence is that there is no extra entity called sense-datum or appearance between a subject-in-itself and a real external thing-in-itself. That is, we see books, not book-images. The possible reply would be that a person sees no mental pictures except that which they see via pictures. (shrink)

I will use three simple arguments to refute the thesis that I appear to directly perceive a mind-independent material object. The theses I will use are similar to the time-gap argument and the argument from the relativity of perception. The visual object of imagination and the object of experience are in the same place. They also share common qualities such as the content, subjectivity, change in virtue of conditions of observers, and the like. This leads to the conclusion (...) that both a tree-image and a tree-experience are distinct from a material tree. Perception of an object is caused by human nature, the senses and consciousness, and mind may prevent the direct perception of the external world. The strongest objection against that consequence is that there is no extra entity called sense-datum or appearance between a subject-in-itself and a real external thing-in-itself.

A new model of the development of temporal concepts is described that assumes that there are substantial changes in how children think about time in the early years. It is argued that there is a shift from understanding time in an event-dependent way to an event-independent understanding of time. Early in development, very young children are unable to think about locations in time independently of the events that occur at those locations. It is only with development (...) that children begin to have a proper grasp of the distinction between past, present, and future, and represent time as linear and unidirectional. The model assumes that although children aged 2 to 3 years may categorize events differently depending on whether they lie in the past or the future, they may not be able to understand that whether an event is in the past or future is something that changes as time passes and varies with temporal perspective. Around 4 to 5 years, children understand how causality operates in time, and can grasp the systematic relations that obtain between different locations in time, which provides the basis for acquiring the conventional clock and calendar system.

This is an excerpt of a report that highlights and explores five questions which arose from The Unity of Consciousness and Sensory Integration conference at Brown University in November of 2011. This portion of the report explores the question: Is the mechanism of sensory integration spatio-temporal?

Against the backdrop of these works (Mitchell/Snyder and others), we propose an analysis of films with and about blind or visually disabled individuals that aims at exploring different modes of world perception. In our view, such an examination should not only discuss the question of “giving voice” and visibility to those who were formerly only represented in or by the media, or the fact that films belonging to what might be considered a “new disability documentary cinema” are dedicated to (...) the experience of disability from the point of view of those who deal with it. Rather, we examine films that do not restrict their field of vision to institutional context as cultural productions. These films allow the viewer to get to know different practices of seeing in the daily life of both blind or visually disabled and sighted people. In approaching these productions, we are interested in focusing on how the audio-visual regimes produce and structure our visual experience, translate it into a filmic grammar and thus not only create filmic patterns of blind perception but, at the same time, the cinematographic aesthetic of a so-called normal sightedness.

Undoubtedly the Penrose-Hameroff Orch OR model may be considered as a good theory for describing information processing mechanisms and holistic phenomena in the human brain, but it doesn’t give us satisfactory explanation of human perception. In this work a new approach explaining our perception is introduced, which is in good agreement with Orch OR model and other mainstream science theories such as string theory, loop quantum gravity and holographic principle. It is shown that human perception cannot be (...) explained in the terms of elementary particles and we should introduce new indivisible holistic objects with geometry based on smooth infinitesimal analysis - elastic membranes. The example of such a membrane is our Universe which is an indivisible whole. It is shown that our perception may be considered as the result of elastic oscillations of two dimensional (2D) elastic membranes with closed topology embedded in our bodies. Only one elastic membrane responsible for its perceptions will correspond to the selected organism, but there may be other membranes, even at the cell level. In other words, reality may be considered as the process of time evolution of holistic energetically very weak macro objects - elastic membranes with the geometry based on smooth infinitesimal analysis. An embedded membrane in this multidimensional world will look different for the external and internal observers: from the outside it will look like a material object with smooth infinitesimal geometry, while from the inside our Universe-like space-time fabric. When interacting with elementary particles and other membranes, a membrane will transform their energy into its elastic energy (a new form of energy) - the energy of stretching of the infinitesimal segments. The theory postulates that these elastic deformations will not be observable from the point of view of the internal observer. Heisenberg’s uncertainty principle will work in this physics only from the point of view of the internal observer. For the external observer each embedded elastic membrane may be stretched and even a very small region will become observable. For example, living organisms play the role of internal observers of the Universe, and at the same time they serve as external observers for 2D membranes embedded into our Universe. We can observe our 2D self-membranes through our perceptions, which are encoded in elastic oscillations of the elastic membrane. According to the theory, elastic membranes occupy energetically favorable positions around microtubules involved into Orch OR. The theory not only gives us a really multidimensional holistic picture of reality, but it also provides us with a new method for understanding such phenomena as perception, self-awareness and will.

A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main conclusions are (...) favored, but her explanation of peripheral–lemniscal couplings is found to be unconvincing. Trevena and Miller's article unsuccessfully tries to rescue a dualist interactionist view. Libet's method of timing intentions is thoroughly criticized. (shrink)

Time has multiple aspects and is difficult to define as one unique entity, which therefore led to multiple interpretations in physics and philosophy. However, if the perception of time is considered as a composite time concept, it can be decomposed into basic invariable components for the perception of progressive and support-fixed time and into secondary components with possible association to unit-defined time or tense. Progressive time corresponds to Bergson’s definition of duration without (...) boundaries, which cannot be divided for measurements. Time periods are already lying in the past and fixed on different kinds of support. The human memory is the first automatic support, but any other support suitable for time registration can also be considered. The true reproduction of original time from any support requires conditions identical to the initial conditions, if not time reproduction becomes artificially modified as can be seen with a film. Time reproduction can be artificially accelerated, slowed down, extended or diminished, and also inverted from the present to the past, which only depends on the manipulation of the support, to which time is firmly linked. Tense associated to progressive and support fixed time is a psychological property directly dependent on an observer, who judges his present as immediate, his past as finished and his future as uncertain. Events can be secondarily associated to the tenses of an observer. Unit-defined time is essential for physics and normal live and is obtained by comparison of support-fixed time to systems with regular motions, like clocks. The association of time perception to time units can also be broken. Einstein’s time units became relative, in quantum mechanics, some physicist eliminated time units, others maintained them. Nevertheless, even the complete elimination of time units is not identical to timelessness, since the psychological perception of progressive and support-fixed time still remains and cannot be ignored. It is not seizable by physical methods, but experienced by everybody in everyday life. Contemporary physics can only abandon the association of time units or tenses to the basic components in perceived time. (shrink)

Modern physics has provided a range of motivations for holding time to be fundamentally undirected. But how does a temporally adirectional metaphysics, or ‘C-theory’ of time, fit with the time of experience? In this chapter, I look at what kind of problem human time poses for C-theories. First, I ask whether there is a ‘hard problem’ of human time: whether it is in principle impossible to have the kinds of experience we do in a temporally (...) adirectional world. Second I consider the ‘easy problem’: how specific directed aspects of our temporal experience are to be explained by C-theorists. This leads to a greater issue: is there such a thing as an experience of time direction at all to even be explained? I show how the kinds of experience we have that we typically associate with the idea of time being directed can be accommodated within a directionless picture of time. (shrink)

In the two feature articles for this volume, Gruber et al and Buonomano & Rovelli focus on what the former call the 'two-times problem', in short, the apparent lack of fit between time as described by physical science and our own temporal experience, where 'experience' involves things like memory, anticipation, and perception of change and motion. In this short note I'll make the case that the twotimes problem is less serious than it is often made out to be (...) in the specific case of features like 'passage ' and 'presentness' that are central to the 'A-theory' of time ---the theory that holds time to be composed of dynamic regions of 'past', 'present' and future', and for time to genuinely flow or pass.My contention is three-fold: (1) the two-times problem is better understood as a three-times problem: rather than a conflict between 'physical' and 'manifest' time, what we have in the case of time is differences between the time of physics, the time of experience, and the 'folk' concept of time. (2) Understanding the problem in this way helps deflate certain problems about the relationship of these three pictures; the time of experience and the time of physics are less obviously in a problematic conflict than often supposed; and the folk concept of time is what brings in problematic features of time hard to fit with either the time of physics of experience. (3) Understanding the time of experience as independent from the folk concept of time better fits the actual aims of the... (shrink)
