This paper explores some issues having to do with the perception of causation. It discusses the role that phenomena that that are associated with causal perception, such as Michottean launching interactions, play within philosophical accounts of causation and also speculates on their possible role in development.

We can perceive not only low-level features of events such as color and motion, but also seemingly higher-level properties such as causality. A prototypical example of causal perception is the ”launching effect’: one object moves toward a stationary second object until they are adjacent, at which point A stops and B starts moving in the same direction. Beyond these motions themselves --- and regardless of any higher-level beliefs --- this display induces a vivid visual impression of causality, wherein (...) A is seen to cause B’s motion. Do such percepts reflect a unitary category of visual processing, or might there be multiple distinct forms of causal perception? While launching is often simply equated with causal perception, researchers have sometimes described other phenomena such as ”triggering’ and ”entraining’. We used psychophysical methods to determine whether these labels really carve visual processing at its joints, and how putatively different forms of causal perception relate to each other. Previous research demonstrated retinotopically specific adaptation to causality: exposure to causal launching makes subsequent ambiguous events in that same location more likely to be seen as non-causal ”passing’. Here, after replicating this effect, we show that exposure to triggering also yields retinotopically specific adaptation for subsequent ambiguous launching displays, but that exposure to entraining does not. Collectively, these results reveal that visual processing distinguishes some types of causal interactions. (shrink)

This is a paper about The Causal Self-Referential Theory of Perception. According to The Causal Self-Referential Theory as developed by above all John Searle and David Woodruff Smith, perceptual content is satisfied by an object only if the object in question has caused the perceptual experience. I argue initially that Searle's account cannot explain the distinction between hallucination and illusion since it requires that the state of affairs that is presented in the perceptual experience must exist in (...) order for the perception to be veridical. Smith's account is interestingly different in that the descriptive content, i.e. the content that presents the perceptual object as having certain properties, does not determine the object of the experience. His account consequently does not require that the state of affairs that is presented in perception exists in order for the perception to have an object. Smith argues instead that perceptual reference is determined by a specific kind of demonstrative content. In this paper it is argued that Smith's account of demonstrative content is too indeterminate and in certain circumstances prescribes the wrong object. It is subsequently argued that the theory of demonstrative content can be modified so as to avoid these consequences. This modification involves deriving the conditions of satisfaction of seeing an object from the conditions of satisfaction of seeing the shape of the object, where the shape of the object is conceived of as a particularized property, what is also called a ‘trope’.

Proponents of the causal theory of perception have applied the theory to questions about which particular objects or events are perceived, which parts are perceived, and which properties are perceived. In each case they insist that successful perception is causally dependent on what is perceived. The causal theory rests on an important insight regarding the information-carrying role of perception. In order to succeed in this role, perception cannot be grounded in spurious correlations. But we (...) can respect this insight without embracing the idea that a successful percept must be causally dependent on what is perceived. A correlation in nature can also be genuine or lawful when it arises from a common cause. I show how successful perception is frequently achieved through correlation via a common cause. (shrink)

ABSTRACTThis article aims to show how the metaphorical and metonymical portrayal of character perception in film can give rise to two distinct but interrelated percepts of causality in the viewer, namely the percept that the viewer sees that an object perceived by a character causes the character’s perception of that object and the percept that the viewer sees that character perception in turn causes a change of state in the perceiving character’s mind. We start our discussion with (...) a brief epistemological overview. Thereby two questions are central: How do people conceptualize perception and causality? and When do people perceive causality in perception? Answers will be given, respectively, by considering insights from cognitive linguistics and experimental psychology. In the next section, then, we bring the theoretical discussion to the foreground of Film Studies by showing how the conceptual solutions, as suggested in the prior part, can manifest themselves i...

People can discriminate the synchrony between audio-visual scenes. However, the sensitivity of audio-visual synchrony perception can be affected by many factors. Using a simultaneity judgment task, the present study investigated whether the synchrony perception of complex audio-visual stimuli was affected by audio-visual causality and stimulus reliability. In Experiment 1, the results showed that audio-visual causality could increase one's sensitivity to audio-visual onset asynchrony (AVOA) of both action stimuli and speech stimuli. Moreover, participants were more tolerant of AVOA of (...) speech stimuli than that of action stimuli in the high causality condition, whereas no significant difference between these two kinds of stimuli was found in the low causality condition. In Experiment 2, the speech stimuli were manipulated with either high or low stimulus reliability. The results revealed a significant interaction between audio-visual causality and stimulus reliability. Under the low causality condition, the percentage of “synchronous” responses of audio-visual intact stimuli was significantly higher than that of visual_intact/auditory_blurred stimuli and audio-visual blurred stimuli. In contrast, no significant difference among all levels of stimulus reliability was observed under the high causality condition. Our study supported the synergistic effect of top-down processing and bottom-up processing in audio-visual synchrony perception. (shrink)

Aristotle grants perceptible qualities the power to generate sense perception in animals. But it is unclear whether, for him, these qualities can produce any effect other than perception. In this paper, I address this issue through a novel approach. To show that they can produce non-perceptual effects, I explore contexts in his extant works where qualities appear to do causal work in nature without leading to perception in animals. This inquiry aims to demonstrate that Aristotle’s realism (...) about qualities survives a potential threat posed by views that dispute the qualities’ causal efficacy outside perception. (shrink)

It is generally agreed upon that Grice's causal theory of perception describes a necessary condition for perception. It does not describe sufficient conditions, however, since there are entities in causal chains that we do not perceive and not all causal chains yield perceptions. One strategy for overcoming these problems is that of strengthening the notion of causality. Another is that of specifying the criteria according to which perceptual experiences should match the way the world is. (...) Finally, one can also try to provide sufficient conditions by elaborating on the content of perceptual experiences. These different strategies are considered in this paper, with the conclusion that none of them is successful. However, a careful examination of their problems points towards the general solution that we outline at the end. (shrink)

This paper responds to critical commentaries on my book, Perceiving Reality (OUP, 2012), by Laura Guerrero, Matthew MacKenzie, and Anand Vaidya. Guerrero focuses on the metaphysics of causation, and its role in the broader question of whether the ‘two truths’ framework of Buddhist philosophy can be reconciled with the claim that science provides the best account of our experienced world. MacKenzie pursues two related questions: (i) Is reflexive awareness (svasaṃvedana) identical with the subjective pole of a dual-aspect cognition or are (...) there alternative, perhaps better, ways of understanding this self-intimating character of mental states? (ii) Is perception constitutively intentional or is it representational? Vaidya argues that, in so far as Husserlian phenomenology and Buddhism differ in terms of their fundamental ontological commit- ments, they must be incompatible, thus rendering any cross-cultural philosophical project that seeks their rapprochement tenuous. One of my aims in Perceiving Reality is to show how accounts of perception informed by metaphysical realism can be problematic on both metaphysical and epistemological grounds, especially when relying on conceptions of consciousness that ignore its properly phenomenological features.

One of the primary motivations behind moral anti-realism is a deep-rooted scepticism about moral knowledge. Moral realists attempt counter this worry by sketching a plausible moral epistemology. One of the most radical proposals in the recent literature is that we know moral facts by perception – we can literally see that an action is wrong, etc. A serious objection to moral perception is the causal objection. It is widely conceded that perception requires a causal connection (...) between the perceived and the perceiver. But, the objection continues, we are not in appropriate causal contact with moral properties. Therefore, we cannot perceive moral properties. This papers demonstrates that the causal objection is unsound whether moral properties turn out to be secondary, natural properties; non-secondary, natural properties; or non-natural properties. 1.

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a (...) clock and brain stimulation). They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:94 HUME ON THE PERCEPTION OF CAUSALITY Introduction Few issues in philosophy have generated as much debate and as little agreement as Hume's controversial theory of causality. The theory itself has been notoriously difficult to pin down, and not surprisingly empirical evidence has played a very minor role in the issue of what is meant by 'cause'. This is not, however, due to the fact that empirical tests (...) of the theory are hard to devise, but rather because such tests have usually been undertaken by experimental psychologists addressing slightly different issues and unaware of the philosophical implications of their work. However, recent signs of agreement on the overall nature of the theory (reviewed in Beauchamp and Rosenberg, chapter 1) allow a profitable integration of the theory with psychological research on the nature and importance of the perception of causal relations in conditioning. The significance of some of these experiments will be discussed later, and it will be argued that the factors Hume cited as being the essential determinants of causality, when complemented by the additional factor of the degree of contingency between the cause and the effect, correspond exactly with the factors known to affect conditioning; and therefore, that the laws of conditioning specify the properties that define causal relationships. Hume's Theory of Causality Hume was well aware of the importance of causal connections between events as a source of associations in the mind: 95 'Tis sufficient to observe, that there is no relation, which produces a stronger connexion in the fancy, and makes one idea more readily recall another, than the relation of cause and effect betwixt their objects (T II).2 In other words, if we believe a causal relationship exists between two events, then one of these events, the cause, will readily recall the other, the effect. The problem comes, of course, when we ask how it is that we know that a causal relationship exists. Obviously, a distinction must be made between causation as a physical property and causality as a mental idea. Traditionally, the following definitions have been made: causation is the physical property of one event causing another, such as one ball colliding with and causing the movement of a second ball. This property is part of the realm of mechanics and physics. Causality, on the other hand, describes the attribution by an organism of an effect to a cause. Such a distinction is supported by dictionary definitions. These two ways of thinking of what is meant by the term 'cause' are explicitly discussed by Hume. On the notion of physical causation, he says: We may define a CAUSE to be 'An object precedent and contiguous to another, and where all the objects resembling the former are plac'd in like relations of precedency and contiguity to those objects, that resemble the latter.' Of the mental idea of a causal relationship, on the other hand, he says: A CAUSE is an object precedent and contiguous to another, and so united with it, that the idea of the one determines the mind to form the idea of the other, and the impression of the one to form a more lively idea of the other. (T 170) Unfortunately, Hume was never less than imprecise in maintaining this dissociation, and often 96 he plainly confused the two definitions. Hence the academic controversy, between those who, like Kemp Smith, believe that the second definition represents a misguided attempt by Hume to analyse the causal relation on a mental level, 3 and those who see both definitions as essential (e.g. Beauchamp and Rosenberg). But surely the first definition simply represents Hume's view of causality as a philosophical relation, while the second represents his view of it as a psychological fact. And it is as much his intention to explain this fact, that ideas do not simply come into our heads for no apparent reason, but on the contrary are summoned up by preceding thoughts which they are associated, as it is to elucidate the philosophical relation. The extent of Hume's commitment to a psychological explanation of causal attribution has been recognised by Beauchamp and Rosenberg: 5 Hume plainly did develop a theory of causal... (shrink)

Since the time of Hume and Maine de Biran there have been two dominant views concerning our experience or perception of causality: Humians maintain that there is no direct experience of a causal link between successive events, while followers of Maine de Biran have argued that there is an internal experience of causality. By devising a series of ingenious experiments, Michotte attempts to show that both traditions are mistaken, and that there are causal impressions in the realm (...) of external experience. Whether or not one agrees with Michotte's conclusions, this study does effectively show the relevance of experimental data to an understanding of the perception of causality. There is a forward by R. C. Oldfield, several appendices bringing the research up to date, and a helpful commentary by T. R. Miles.—R. J. B. (shrink)

It is widely held by philosophers not only that there is a causal condition on perception but also that the causal condition is a conceptual truth about perception. One influential line of argument for this claim is based on intuitive responses to a style of thought experiment popularized by Grice. Given the significance of these thought experiments to the literature, it is important to see whether the folk in fact respond to these cases in the way (...) that philosophers assume they should. We test folk intuitions regarding the causal theory of perception by asking our participants to what extent they agree that they would ‘see’ an object in various Gricean scenarios. We find that the intuitions of the folk do not strongly support the causal condition; they at most strongly support a ‘no blocker’ condition. We argue that this is problematic for the claim that the causal condition is a conceptual truth. (shrink)

This paper seeks to show how a proper version of dispositionalism, taking powers as basic elements of reality, may figure as a causal theory of perception. On the basis of this argument, the paper draws some further conclusions, which may indicate the explanatory competence of such a disposition-affine theory of causality, for example in terms of the distinction between primary and secondary qualities, as well as an ontological account of mere potentialities of active capacities to perceive and of (...) “privations,” respectively.
