According to the Common Ground account proposed by Stalnaker, speakers involved in a verbal interaction have different propositional attitudes towards presuppositions. In this paper we propose an experimental study aimed at estimating the psychological plausibility of the Stalnakerian model. In particular, the goal of our experiment is to evaluate variations in accepting as appropriate a sentence that triggers a presupposition, where different attitudes are taken towards the presupposition required. The study conducted suggests that if a speaker has the attitude of (...) belief towards the content of a presupposition, she may evaluate an utterance as more appropriate in a shorter time than in cases where she holds an attitude of presumption or of assumption. Therefore, data collected support the psychological soundness of what might be considered the main, but also most debated, theory of presupposition on the market. (shrink)

Research on electroencephalogram (EEG) characteristics associated with major depressive disorder (MDD) has accumulated diverse neurophysiologic findings related to the content, topography, neurochemistry, and functions of EEG oscillations. Significant progress has been made since the first landmark EEG study on affective disorders by Davidson 35 years ago. A systematic account of these data is important and necessary for building a consistent neuropsychophysiologic model of MDD and other affective disorders. Given the extensive data on frequency-dependent functional significance of EEG oscillations, a frequency (...) domain approach may reveal the types of brain functions involved and disturbed in MDD. In this review, we systematize and integrate diverse and often unconnected observations on the content, topography, neurochemistry, and functions of EEG oscillations involved in MDD within the general concept of an EEG oscillatory pattern.

Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, (...) that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory led to transitive causal judgments. On the other hand, chains schematized as multiple chunks led to intransitive judgments despite strong intermediate links. Normative accounts of causal intransitivity could not explain these intransitive judgments. (shrink)

In this paper we investigate how the dynamic nature of words’ meanings plays a role in a philosophical theory of meaning. For ‘dynamic nature’ we intend the characteristic of being flexible, of changing according to many factors (speakers, contexts, and more). We consider meaning as something that gradually takes shape from the dynamic processes of communication. Accordingly, we present a draft of a theory of meaning that, on the one hand, describes how a private meaning is formed as a mental (...) state of individual agents during a lifetime of experiences, and, on the other hand, shows how a public meaning emerges from the interaction of agents. When communicating with each other, agents need to converge on a shared meaning of the words used, by means of a negotiation process. A public meaning is the abstract product of many of these processes while, at the same time, the private meanings are continually reshaped by each negotiation. Exploring this dynamics, we have been looking at the work done by computer scientists dealing with problems of heterogeneity of sources of information. We argue that a suitable solution for both disciplines lies in a systematic characterization of the processes of meaning negotiation. (shrink)

The computational paradigm, which has dominated psychology and artificial intelligence since the cognitive revolution, has been a source of intense debate. Recently, several cognitive scientists have argued against this paradigm, not by objecting to computation, but rather by objecting to the notion of representation. Our analysis of these objections reveals that it is not the notion of representation per se that is causing the problem, but rather specific properties of representations as they are used in various psychological theories. Our analysis (...) suggests that all theorists accept the idea that cognitive processing involves internal information-carrying states that mediate cognitive processing. These mediating states are a superordinate category of representations. We discuss five properties that can be added to mediating states and examine their importance in various cognitive models. Finally, three methodological lessons are drawn from our analysis and discussion. (shrink)

Using a cross‐modal semantic priming paradigm, both experiments of the present study investigated the link between the mental representations of iconic gestures and words. Two groups of the participants performed a primed lexical decision task where they had to discriminate between visually presented words and nonwords (e.g., flirp). Word targets (e.g., bird) were preceded by video clips depicting either semantically related (e.g., pair of hands flapping) or semantically unrelated (e.g., drawing a square with both hands) gestures. The duration of gestures (...) was on average 3,500 ms in Experiment 1 but only 1,000 ms in Experiment 2. Significant priming effects were observed in both experiments, with faster response latencies for related gesture–word pairs than unrelated pairs. These results are consistent with the idea of interactions between the gestural and lexical representational systems, such that mere exposure to iconic gestures facilitates the recognition of semantically related words.

Studies based on the Contemporary Theory of Metaphor (Lakoff & Johnson, 1980, 1999) usually identify conceptual metaphors by analysing linguistic expressions and creating a post hoc interpretation of the findings. This method has been questioned for a variety of reasons, including its circularity (Müller, 2008), lack of falsifiability (Vervaeke & Kennedy, 1996, 2004), and lack of predictive power (Ritchie, 2003). It has been argued that CTM requires additional constraints to improve its applicability for empirical research (Gibbs, 2011; Ritchie, 2003). This (...) paper sets out to propose additional methodological structure to CTM, a theory of conceptual metaphor in which much of abstract thought is generated by metaphorical mapping from embodied experience (Ruiz de Mendoza Ibáñez & Pérez Hernández, 2011). Introducing Objectification Theory defined by Szwedek (2002, 2007, 2011) ameliorates a number of methodological issues in CTM. First, the embodiment claim of CTM in its current form cannot be empirically proven incorrect (Vervaeke & Kennedy, 2004) as any mapping within it is possible (although only some actually happen). Objectification introduces pre-metaphorical structure of the kind suggested by Glucksberg (2001), constraining source and target domain selection, predicting which mappings are more likely to happen. Second, while many claim that metaphors trace back to a literal concept based on embodied physical experience (Gibbs, Costa Lima, & Francozo, 2004), it is unclear what criteria are used to define „physical”. Metaphorical domains are often described using the terms „abstract” and „concrete”, Objectification proposes objective criteria for deciding whether a concept is experientially grounded. Finally, Objectification provides grounds for introducing a hierarchical framework for metaphor typology, preventing post-hoc addition of metaphor types if and when suitable for the explanation of a phenomenon; thus increasing the consistency of the CTM framework, both internally and with other cognitive science disciplines. This thesis focuses on providing evidence for Objectification Theory and identifying its applications in metaphor and gesture research. (shrink)

The single-word semantic priming paradigm is a tool for investigating how and when word meaning activation occurs during visual word recognition. The prime task effect refers to the elimination of the typically robust semantic priming effect by a nonsemantic prime task . The purpose of this paper is to provide a tutorial review of the literature examining the prime task effect. Understanding the nature of this effect has implications for delineating how selective attention modulates evidence for semantic activation during word (...) reading. These implications are outlined. Additionally, speculations for how these issues of selective attention relate to awareness are offered. (shrink)

Contextual vocabulary acquisition (CVA) is the deliberate acquisition of a meaning for a word in a text by reasoning from context, where “context” includes: (1) the reader’s “internalization” of the surrounding text, i.e., the reader’s “mental model” of the word’s “textual context” (hereafter, “co-text” [3]) integrated with (2) the reader’s prior knowledge (PK), but it excludes (3) external sources such as dictionaries or people. CVA is what you do when you come across an unfamiliar word in your reading, realize that (...) you don’t know what it means, decide that you need to know what it means in order to understand the passage, but there is no one around to ask, and it is not in the dictionary (or you are too lazy to look it up). In such a case, you can try to figure out its meaning “from context”, i.e., from clues in the co-text together with your prior knowledge. Our computational theory of CVA—implemented in a the SNePS knowledge representation and reasoning system [28]—begins with a stored knowledge base containing SNePS representations of relevant PK, inputs SNePS representations of a passage containing an unfamiliar word, and draws inferences from these two (integrated) information sources. When asked to define the word, definition algorithms deductively search the resulting network for information of the sort that might be found in a dictionary definition, outputting a definition frame whose slots are the kinds of features that a definition might contain (e.g., class membership, properties, actions, spatio-temporal information, etc.) and whose slot-fillers contain information gleaned from the network [6–8,20,23,24]. We are investigating ways to make our system more robust, to embed it in a naturallanguage-processing system, and to incorporate morphological information. Our research group, including reading educators, is also applying our methods to the develop-. (shrink)

Measures and theories of information abound, but there are few formalised methods for treating the contextuality that can manifest in different information systems. Quantum theory provides one possible formalism for treating information in context. This paper introduces a quantum inspired model of the human mental lexicon. This model is currently being experimentally investigated and we present a preliminary set of pilot data suggesting that concept combinations can indeed behave non-separably.

Do AI programs just make it quicker and easier for humans to do what they can do already, or can the range of do-able things be extended? This paper suggests that cognitively-oriented technology can make it possible for humans to construct and carry out mental operations, which were previously impossible. Probable constraints upon possible human mental operations are identified and the impact of cognitive technology upon them is evaluated. It is argued that information technology functions as a cognitive prosthetic enhancing (...) human intelligence and planning capabilities. Boundaries and constraints which Kant, Whorf, and many post-modernist theorists have seen as intrinsic to human cognition now cease to apply. (shrink)

The nature of cultural organization remains an open anthropological question. Although we eschew any simplistic global reductionism, here we argue that three organizational features of culture, its systematicity; the recurrence of distinctions across semantic, conceptual and practical boundaries; and the 'bleeding' of properties between associated concepts, may find their origin in fundamental operating principles of the human mind: respectively, the cognitive principle of relevance, the decompositionality of cognitive processing and the network structure of semantic memory. The reframing of some features (...) of culture in cognitive terms may open up some ethnographic observations, so far resistant to anthropological explanation, to new avenues for theory and relevant data from other disciplines.

O'Brien & Opie's (O&O's) theory demands a view of unconscious processing that is incompatible with virtually all current PDP models of neural activity. Relative to the alternatives, the theory is closer to an AI than a parallel distributed processing (PDP) perspective, and its treatment of phenomenology is ad hoc. It raises at least one important question: Could features of network relaxation be the “switch” that turns an unconscious into a conscious network?

Preparing words in speech production is normally a fast and accurate process. We generate them two or three per second in fluent conversation; and overtly naming a clear picture of an object can easily be initiated within 600 msec after picture onset. The underlying process, however, is exceedingly complex. The theory reviewed in this target article analyzes this process as staged and feedforward. After a first stage of conceptual preparation, word generation proceeds through lexical selection, morphological and phonological encoding, phonetic (...) encoding, and articulation itself. In addition, the speaker exerts some degree of output control, by monitoring of self-produced internal and overt speech. The core of the theory, ranging from lexical selection to the initiation of phonetic encoding, is captured in a computational model, called WEAVER++. Both the theory and the computational model have been developed in interaction with reaction time experiments, particularly in picture naming or related word production paradigms, with the aim of accounting for the real-time processing in normal word production. A comprehensive review of theory, model, and experiments is presented. The model can handle some of the main observations in the domain of speech errors (the major empirical domain for most other theories of lexical access), and the theory opens new ways of approaching the cerebral organization of speech production by way of high-temporal-resolution imaging.

This paper replies to the first 36 commentaries on my target article on “Is human information processing conscious?” (Behavioral and Brain Sciences,1991, pp.651-669). The target article focused largely on experimental studies of how consciousness relates to human information processing, tracing their relation from input through to output, while discussion of the implications of the findings both for cognitive psychology and philosophy of mind was relatively brief. The commentaries reversed this emphasis, and so, correspondingly, did the reply. The sequence of topics (...) in the reply roughly follows that of the target article. The discussion begins with a reconsideration of the details of the empirical findings, whether they can be extrapolated to non-laboratory settings, and the extent to which one can rely on their use of subjective reports. This is followed by an in-depth discussion of what is meant by “conscious processing” and of how phenomenal consciousness relates to attentional processing. We then turn to broader philosophical and theoretical issues. I point out some of the reasons why I do not support epiphenomenalism, dualist-interactionism, or reductionism, and elaborate on how first- and third-person views of the mind can be regarded as complementary and mutually irreducible. I suggest how the relation of conscious experiences to their neural correlates can be understood in terms of a dual-aspect theory of information,and how this might be used to resolve some of the paradoxes surrounding the causal interactions of consciousness and brain. I also suggest that, viewed from a first-person perspective, consciousness gives purpose to existence, which allows a different way of viewing its role in evolution. (shrink)

Many traditional theories of creativity put heavy emphasis on an incubation stage in creative cognitive processes. The basic phenomenon is a familiar one: we are working on a task or problem, we leave it aside for some period of time, and when we return attention to the task we have some new insight that services completion of the task. This feature, combined with other ostensibly mysterious features of creativity, has discouraged naturalists from theorizing creativity. This avoidance is misguided: we can (...) maintain unconscious incubated cognition as (sometimes) part of the creative process and we can explain it in scientifically responsible ways. This paper, focusing on the effects of attention on the functional networking of the brain, attempts just such an explanation. It also serves to assuage the naturalist's scepticism about other features of creative cognition. The broad upshot, one would hope, is that philosophers of mind and cognitive scientists return some attention to the long neglected topic of creativity. (shrink)

Information processing theories in psychology give rise to executive theories of consciousness. Roughly speaking, these theories maintain that consciousness is a centralized processor that we use when processing novel or complex stimuli. The computational assumptions driving the executive theories are closely tied to the computer metaphor. However, those who take the metaphor serious — as I believe psychologists who advocate the executive theories do — end up accepting too particular a notion of a computing device. In this essay, I examine (...) the arguments from theoretical computational considerations that cognitive psychologists use to support their general approach in order to show that they make unwarranted assumptions about the processing attributes of consciousness. I then go on to examine the assumptions behind executive theories which grow out of the computer metaphor of cognitive psychology and conclude that we may not be the sort of computational machine cognitive psychology assumes and that cognitive psychology''s approach in itself does not buy us anything in developing theories of consciousness. Hence, the state space in which we may locate consciousness is vast, even within an information processing framework. (shrink)

The computational view of mind rests on certain intuitions regarding the fundamental similarity between computation and cognition. We examine some of these intuitions and suggest that they derive from the fact that computers and human organisms are both physical systems whose behavior is correctly described as being governed by rules acting on symbolic representations. Some of the implications of this view are discussed. It is suggested that a fundamental hypothesis of this approach is that there is a natural domain of (...) human functioning that can be addressed exclusively in terms of a formal symbolic or algorithmic vocabulary or level of analysis. Much of the paper elaborates various conditions that need to be met if a literal view of mental activity as computation is to serve as the basis for explanatory theories. The coherence of such a view depends on there being a principled distinction between functions whose explanation requires that we posit internal representations and those that we can appropriately describe as merely instantiating causal physical or biological laws. In this paper the distinction is empirically grounded in a methodological criterion called the " cognitive impenetrability condition." Functions are said to be cognitively impenetrable if they cannot be influenced by such purely cognitive factors as goals, beliefs, inferences, tacit knowledge, and so on. Such a criterion makes it possible to empirically separate the fixed capacities of mind from the particular representations and algorithms used on specific occasions. In order for computational theories to avoid being ad hoc, they must deal effectively with the "degrees of freedom" problem by constraining the extent to which they can be arbitrarily adjusted post hoc to fit some particular set of observations. This in turn requires that the fixed architectural function and the algorithms be independently validated. It is argued that the architectural assumptions implicit in many contemporary models run afoul of the cognitive impenetrability condition, since the required fixed functions are demonstrably sensitive to tacit knowledge and goals. The paper concludes with some tactical suggestions for the development of computational cognitive theories. (shrink)

Investigations of the function of consciousness in human information processing have focused mainly on two questions: (1) where does consciousness enter into the information processing sequence and (2) how does conscious processing differ from preconscious and unconscious processing. Input analysis is thought to be initially "preconscious," "pre-attentive," fast, involuntary, and automatic. This is followed by "conscious," "focal-attentive" analysis which is relatively slow, voluntary, and flexible. It is thought that simple, familiar stimuli can be identified preconsciously, but conscious processing is needed (...) to identify complex, novel stimuli. Conscious processing has also been thought to be necessary for choice, learning and memory, and the organization of complex, novel responses, particularly those requiring planning, reflection, or creativity.

Metaphors can provide a conceptual framework for understanding complex topics and as such, they have frequently been used in COVID-19 discourse. As previous research indicates that conceptual metaphors can influence how people reason about complex topics, the metaphors used to communicate about the pandemic can influence how it is understood and how people respond. This paper investigates the influence of metaphorical framing on emotions and reasoning. An experimental study compares BATTLE and JOURNEY metaphor frames in a hypothetical text (adapted from (...) previous studies) about the pandemic. Our aim is to examine the influence of these frames on readers’ affective state, inferences about the attitudes of others and suggestions to stop the virus from spreading. The results suggest that compared to JOURNEY metaphors, BATTLE metaphors can negatively influence affective state and may influence people to suggest more restrictive solutions to reduce the spread of the virus. Yet, metaphors were not found to influence reasoning about the attitudes of others. We interpret these results in relation to previous studies, suggesting that metaphors may influence emotions and reasoning in some ways only. The results have implications for public communication surrounding the pandemic. Limitations and avenues for future research are discussed. (shrink)

During the idea generation phase of the design process, designers often search for inspirations in external sources of information, such as photographs, written descriptions and physical examples. These sources have potential to enhance creative performance. However, they sometimes become too attached to particular ideas of external precedents or various examples. It refers to fixation which is identified as inadequate adoption of features from existing examples. Influence of the existing examples on creativity and fixation, specifically textual examples, have been discussed in (...) this research. -/- For the nature of design, researchers highlighted the restructuring process of design problem by new sources because the capabilities and boundaries of design problems are not defined very well. Further, the design problem is not knowable at any specific point. Design knowledge identifies itself by its ambiguity. Many models have been developed for design process. The various numbers of divided phases of the models can be seen as having two main areas: (1) idea generation phase (or “ideation”); (2) later phase for details. Idea generation plays an important role in the design process. It is the area of new and creative configurations on design. -/- Creativity is an integral part of the design process. Designers purpose to achieve original ideas to demonstrate their ability and unique designs. External stimuli or inspirational inputs play important roles to increase creativity. They can support moments of stimulation. Associations between information from memory and external stimuli can contribute to the creation of new meanings. Designers are widely influenced by their surroundings in daily lives. However, each stimulus may not be the part of a more creative result Even if designers want to utilize stimulus as an inspirational source, somehow it may fixate their mind to its surface features and they may lose potential creative contributions of the source. It is called fixation. There is much research that shows significant evidence of conformity effects across the design problems. -/- The given examples to designers may cause higher-level fixation and lower-level creativity or vice versa. Fixation may occur when example solutions are introduced, on the other hand, the designers may create more original ideas as well. There is a need for research to find ways to avoid fixation traps or reduce their adverse impact. Thus, this research focuses on variables of the given example. -/- The following claims show some research areas remained unclear: (1) Some researchers investigated textual examples as - one of the modalities of representation - but did not focus on forms of textual examples. (2) Much research has been conducted with examples which are selected by the researcher. Nevertheless, designers can also choose or produce their own stimuli. There is not much research on this possibility. In this context, my research focuses on the following two variables through two studies (Study 1 and 2): (1) forms of textual examples; (2) self-construction of textual examples. First, most of the studies in the literature have focused on visual presentation and there is not enough research on the content and form of the text. The study of textual examples has still not been awarded enough attention especially as various forms of text. Some forms of text are as follows: keyword, paragraph, sentence, poem. These observations lead me to the following research question: Which forms of textual example increase creativity and reduce fixation more? (Study 1). -/- Second, most of the studies regarding textual examples have used prose or keywords. The poems have been ignored. However, poems imply more meaning with fewer words. The structure of the poems enables more creative narratives than structure of prose. Because unusual organization of words stimulates the readers and draws their attention. This activates the creative performance of the reader. The surrealist poem is the extreme form of this activation. It is random assemblies with headlines and sentences which is cut from newspapers. Thus, novel meaning networks are formed. The method of creating a surrealist poem offers a new way of getting inspiration. It is termed as self-construction practice by this research. Through this method, designers create their own example from the given one. Reconstruction of the text may increase the creative process and prevent fixations from the given text. This suggestion led me to the following research question: If the designers write their own poem instead of a given poem (as a self-construction practice), can they internalize the textual example? In addition, does it produce more creative and less fixated designs? (Study 2). Two experimental studies were planned to partially answer the research questions, in which novice students of architecture were asked to solve two different design problems, under different conditions. All of the experimental sessions were conducted in a design education studio. The participants produced sketches and added a written explanation relating to their designs. Fluency, flexibility and repetition of key attributes were calculated by the researcher. -/- Originality, practicality, understanding of the task and quality were ranked by judges. Study 1 shows us tendencies of using various textual forms. Distinctions of keywords and of poems have appeared among them. This emphasizes the role of keyword and poem in the design process as inspirational sources and provides many tips for their potential use. The keyword also leads to a high degree of fixation. However, a low degree of fixation is observed when poems are presented as inspirational examples. -/- In Study 2, the self-constructed poem seems to support develop more successful design ideas from many perspectives. In the context of the surrealist poem, writing and reading the surrealist poem trigger the designers’ imagination. At first, the words and lines of poems seem unrelated to each other and designers try to relate them and solve the puzzle of meaning. Hence, novel meaning networks are formed. It indicates that surrealist poems are able to activate the creative performance of the designers. Writing their own surrealist poems ,as a self-construction practice, motivated designers to begin to produce by having fun. Motivated designers have stimulated themselves to produce creative ideas. In other words, the self-construction process may be added to the design process models in the earlier part of the idea generation phase which is called as pre-design and warm-up phase. This earlier phase makes designers highly motivated and they internalized the given examples. -/- Following the conclusions, several implications and recommendations for the design process and education are discussed.

Curiosity and creativity are central pillars of human growth and invention. Although they have been studied extensively in isolation, the relationship between them has not yet been established. We propose that both curiosity and creativity emanate from the same mechanism of novelty seeking. We first present a synthesis showing that curiosity and creativity are affected similarly by a number of key cognitive faculties such as memory, cognitive control, attention, and reward. We then review empirical evidence from neuroscience research, indicating that (...) the same brain regions are involved in both curiosity and creativity, focusing on the interplay between three major brain networks: the default mode network, the salience network, and the executive control network. After substantiating the link between curiosity and creativity, we propose a novelty-seeking model (NSM) that underlies them and suggests that the manifestation of the NSM is governed by one's state of mind.
