Ferdinand Pöhlmann argues that a sense of one’s own basic abilities to move is a constitutive condition on the ability to perceive the world spatially. This constitutive relation explains why egocentric spatial representation is to be regarded as a kind of self-representation. In arguing for these claims, conceptual as well as empirical questions are discussed and an overview of accounts that take action as a constitutive condition on spatial representation is given. The picture that emerges is linked to the phenomenological (...) (Scheler) as well as to the analytic (Evans) tradition in the Philosophy of Mind.​. (shrink)

Theories of picture perception aim to understand our perceptual relation to both the picture surface and the depicted object. I argue that we should talk about not two, but three entities when understanding picture perception: the picture surface, the three dimensional object the picture surface visually encodes and the three dimensional depicted object. As and can come apart, we get a more complex picture of picture perception than normally assumed and one where the notion of twofoldness, which has played an (...) important albeit controversial role in understanding picture perception is replaced by the concept of threefoldness.

Everyday life suggests that picture seeing is sometimes infused by an emotional charge. However, nobody has addressed the importance of explaining this emotional charge in picture perception. Even our best model of picture perception, the dorsal/ventral account of picture perception, which integrates the most important empirical results coming from our best model on vision in neuroscience, the two visual systems model, lacks a reference to this emotional charge. The aim of the present paper is to offer an account of picture (...) perception that is able to regain and explain this neglected emotional charge. My claim is that, as for face-to-face perception, during picture perception, we are not only in a visual perceptual state, but also in an emotional state, which is directly connected to our visual perceptual state. I also show that it is possible to offer this integration while remaining in the philosophical/empirical framework of the dorsal/ventral account of picture perception, whose explanatory power is confirmed and improved.

Philosophers of music, like Charles Swann in Proust’s novel (Proust 1913/1992, p. 360), have traditionally found it difficult to utter the word ‘profound’ unironically. But this changed with Peter Kivy’s 1990 paper ‘The profundity of music’ The problem Kivy draws our attention to is this: we do call some musical works profound. However, Kivy argues, given that a work is profound only if it is about something profound and given that music (or ‘music alone’) is not about anything, this leads (...) to something of a paradox: how can music be profound if it is not about something profound. My aim in this paper is to argue that what makes a work profound is not that it is about something profound, but that it actively challenges any straightforward interpretative activity (while at the same time nudges you to keep on trying to interpret it). I argue that this line of argument is very much in tune with Kivy’s general theoretical commitment that “music alone isn’t about anything” (Kivy 1990, p. 245). (shrink)

Picture perception and ordinary perception of real objects differ in several respects. Two of their main differences are: Depicted objects are not perceived as present and We cannot perceive significant spatial shifts as we move with respect to them. Some special illusory pictures escape these visual effects obtained in usual picture perception. First, trompe l'oeil paintings violate : the depicted object looks, even momentarily, like a present object. Second, anamorphic paintings violate : they lead to appreciate spatial shifts resulting from (...) movement. However, anamorphic paintings do not violate : they are still perceived as clearly pictorial, that is, nonpresent. What about the relation between trompe l'oeil paintings and? Do trompe l'oeils allow us to perceive spatial shifts? Nobody has ever focused on this aspect of trompe l'oeil perception. I offer the first speculation about this question. I suggest that, if we follow our most recent theories in philosophy and vision science about the mechanisms of picture perception, then, the only plausible answer, in line with phenomenological intuitions, is that, differently from nonillusory, usual picture perception, and similarly to ordinary perception, trompe l'oeil perception does allow us to perceive spatial shifts resulting from movement. I also discuss the philosophical implications of this claim. (shrink)

Philosophers have suggested that, in order to understand the particular visual state we are in during picture perception, we should focus on experimental results from vision neuroscience—in particular, on the most rigorous account of the functioning of the visual system that we have from vision neuroscience, namely, the ‘Two Visual Systems Model’. According to the initial version of this model, our visual system can be dissociated, from an anatomo-functional point of view, into two streams: a ventral stream subserving visual recognition, (...) and a dorsal stream subserving the visual guidance of action. Following this model, philosophers have suggested that, since the two streams have different functions, they represent different properties of a picture. However, the original view proposed by the ‘Two Visual Systems Model’ about the presence of a strong anatomo-functional dissociation between the two streams has recently been questioned on both philosophical and experimental grounds. Indeed, the analysis of several new pieces of evidence seems to suggest that many visual representations in our visual system, related to different tasks, are the result of a deep functional interaction between the streams. In the light of the renewed status of the ‘Two Visual Systems Model’, also our best philosophical model of picture perception should be renewed, in order to take into account a view of the process of picture perception informed by the new evidence about such interaction. Despite this, no account fulfilling this role has been offered yet. The aim of the present paper is precisely to offer such an account. It does this by suggesting that the peculiar visual state we are in during picture perception is subserved by interstream interaction. This proposal allows us to rely on a rigorous philosophical account of picture perception that is, however, also based on the most recent results from neuroscience. Unless the explanation offered in this paper is endorsed, all the recent evidence from vision neuroscience will remain unexplained under our best empirically informed philosophical theory of picture perception.

Does action play any crucial role in our perception of pictures? The standard literature on picture perception has never explicitly tackled this question. This is for a simple reason. After all, objects in a picture seem to be static objects of perception. Thus, it might sound extremely controversial to say that action is crucial in picture perception. Contrary to this general intuitive stance, this paper defends, for the first time, the apparently very controversial claim, never addressed in the literature, that (...) some of the specific and essential relations between vision and action make action (and its motoric basis) crucial in order for us to enter pictorial experience. I first discuss two ways in which vision and action are deeply linked, by describing the famous notions of Vision-for-Action and Sensorimotor Understanding. Then, I describe the special role they play in generating ordinary pictorial experience and suggest that, when we cannot rely on them while in front of a picture, we lose pictorial experience.

Philosophers suggested that usual picture perception requires the simultaneous occurrence of the perception of the surface and of the depicted object. However, there are special cases of picture perception, such as trompe l'oeil perception, in which, unlike in usual picture perception, the object looks like a real, present object we can interact with, of the kind we are usually acquainted with in face-to-face perception. While philosophers suggested that usual picture perception and trompe l'oeil perception must differ with respect to the (...) perception of the surface, nobody has ever proposed a final explanatory account for such a difference. Here, I propose such an account. I consider the two possible options as candidates for the explanation of the illusory power of trompe l'oeil perception. The first is that, with trompe l'oeils, we perceive the surface unconsciously. The second is that, with trompe l'oeils, we cannot perceive the surface at all, that is, we cannot perceive it either consciously or unconsciously. I show that the second option is the unique plausible option, as it is in line with vision science, and with our received view about the nature of usual picture perception. (shrink)

Everyday visual experience constantly confronts us with things we can interact with in the real world. We literally feel the outside presence of physical objects in our environment via visual perceptual experience. The visual feeling of presence is a crucial feature of vision that is largely unexplored in the philosophy of perception, and poorly debated in vision neuroscience. The aim of this article is to investigate the feeling of presence. I suggest that visual feeling of presence depends on the visual (...) representation of a very particular spatial relation with the object we interact with: the visual representation of absolute egocentric depth, which is due to stereoscopic vision.

According to the received view in the philosophical literature on pictorial perception, when perceiving an object in a picture, we perceive both the picture’s surface and the depicted object, but the surface is only unconsciously represented. Furthermore, it is suggested, such unconscious representation does not need attention. This poses a crucial problem, as empirical research on visual attention shows that there can hardly be any visual representation, conscious or unconscious, without attention. Secondly, according to such a received view, when looking (...) at a picture aesthetically, one both consciously represents and visually attends to both the depicted object and the picture’s surface simultaneously. Thus, contra the empirical research on attention, only conscious visual representations are coupled, by such current view, with attention. And this clearly poses a second problem, as this philosophical account is not in tune with what vision science tells us about the functioning of our visual system. Furthermore, this raises another crucial problem, namely, that of explaining why aesthetic experience of pictures does not feel odd or conflicting, since, as previously noted in the philosophical literature, and contra the received view, if we are simultaneously consciously perceiving both the picture’s surface and the depicted object, there seems to be two things, at the same time, in the foreground of one’s visual consciousness. But, if so, as suggested, this would lead to a conflicting spatial visual experience. This paper offers a new description of the role of visual attention in picture perception, which explains the difference between the usual and the aesthetic way of perceiving a depicted object, without facing the problems reported above. A crucial role in our new account is played by the notion of unconscious attention, the distinction between focal and distributed, as well as top-down and bottom-up visual attention and the relationship between visual attention and visual consciousness. The paper, thus, offers the first theory concerning the exercise of visual attention in pictorial perception that is both philosophically rigorous and empirically reliable. (shrink)

The most important question concerning picture perception is: what perceptual state are we in when we see an object in a picture? In order to answer this question, philosophers have used the results of the two visual systems model, according to which our visual system can be divided into two streams, a ventral stream for object recognition, allowing one to perceive from an allocentric frame of reference, and a dorsal stream for visually guided motor interaction, thus allowing one to perceive (...) from an egocentric frame of reference. Following this model, philosophers denied that we can be in a dorsal perceptual state when perceiving a depicted object. This is because a depicted object is not physically graspable or manipulable and, in turn, it cannot be egocentrically localized, as a normal object, by the dorsal stream. Thus, the impossibility of manipulating depicted objects and of localizing them from an egocentric frame of reference has led some people to be sceptical about the possibility of a representation of action properties in the perception of objects in pictures, which pertains to the dorsal visual system. The aim of the present paper is to show that it is possible for the depicted object to be represented by dorsal perception. That means that we can ascribe action properties to depicted objects as well, even if depicted objects cannot be egocentrically localized—at least, not as much as normal objects can. (shrink)

Philosophers and cognitive scientists try to understand, from different perspectives, the nature of the experience of reality. Given this shared, interdisciplinary interest, it would be beneficial to have a coherent story about the experience of reality, in which there is reciprocal contribution from both philosophy and cognitive science. This paper wants to pave the way for this shared enterprise on the investigation of the experience of reality. I first distinguish between two indicators of reality. (1) The experience of availability to (...) motor interaction. (2) The experience of mind-independence. I then show how invoking an analysis of the results from vision science, concerning the visual mechanisms of stereopsis, which is related to the visual impression of a solid, three-dimensional world available to motor interaction, successfully provides a coherent description of the first indicator. Furthermore, I suggest that the analysis of the evidence about the first indicator is very informative in preparing the ground for the investigation of the second indicator. This is shown by discussing experimental evidence directly related to stereopsis, as well as some perceptual phenomena that are usually described by invoking the story from vision science about stereopsis. Thus, the epistemological analysis of the results from vision science on stereopsis, offered in this paper, is beneficial in a twofold manner, for the interdisciplinary enterprise aimed at understanding the experience of reality. It is explicitly beneficial in the description of the first indicator, and implicitly beneficial to understand the second indicator. Finally, it also suggests future research about their relation.

ABSTRACT:Are face-to-face perception and picture perception different perceptual phenomena? The question is controversial. On the one hand, philosophers have offered several solid arguments showing that, despite some resemblances, they are quite different perceptual phenomena and that pictures are special objects of perception. On the other hand, neuroscientists routinely use pictures in experimental settings as substitutes for normal objects, and this practice is successful in explaining how the human visual system works. But this seems to imply that face-to-face perception and picture (...) perception are very similar, if not actually the same. How can we decide between these two opposite intuitions? Here I offer a regimentation of the notion of picture perception that can reconcile these two apparently conflicting ideas about pictures. It follows that philosophers and neuroscientists can maintain their respective stances without any theoretical conflict. (shrink)
