Plausibly, any adequate theory of perception must (a) solve what Alva Noë calls 'the problem of perceptual presence,' and (b) do justice to the direct realist idea that what is given in perception are garden-variety spatiotemporal particulars. This paper shows that, while Noë's sensorimotor view arguably satisfies the first of these conditions, it does not satisfy the second. Moreover, Noë is wrong to think that a naïve realist approach to perception cannot handle the problem of perceptual presence. Section three of (...) this paper develops a version of naïve realism that meets both of the adequacy conditions above. This paper thus provides strong considerations in favor of naïve realism.

Ecological and sensorimotor theories of perception build on the notion of action-dependent invariants as the basic structures underlying perceptual capacities. In this paper we contrast the assumptions these theories make on the nature of perceptual information modulated by action. By focusing on the question, how movement specifies perceptual information, we show that ecological and sensorimotor theories endorse substantially different views about the role of action in perception. In particular we argue that ecological invariants are characterized with reference to transformations produced (...) in the sensory array by movement: such invariants are transformation-specific but do not imply motor-specificity. In contrast, sensorimotor theories assume that perceptual invariants are intrinsically tied to specific movements. We show that this difference leads to different empirical predictions and we submit that the distinction between motor equivalence and motor-specificity needs further clarification in order to provide a more constrained account of action/perception relations.

Many viewers presented with a round plate tilted to their line of sight will report that they see a round plate that looks elliptical from their perspective. Alva Noë thinks that we should take reports of this kind as adequate descriptions of the phenomenology of spatial experiences. He argues that his so‐called enactive or sensorimotor account of spatial perceptual content explains why both the plate's circularity and its elliptical appearance are phenomenal aspects of experience. In this paper, I critique the (...) phenomenal adequacy of Noë's sensorimotor account of spatial perceptual content. I begin by showing that some of its central claims are in conflict with the phenomenology of perceptual experience. I then argue that shape appearances have no phenomenal reality, thus undermining this central motivation for his account. (shrink)

According to an influential view, one function of mirror neurons (MNs), first discovered in the brain of monkeys, is to underlie third-person mindreading. This view relies on two assumptions: the activity of MNs in an observer’s brain matches (simulates or resonates with) that of MNs in an agent’s brain and this resonance process retrodictively generates a representation of the agent’s intention from a perception of her movement. In this paper, I criticize both assumptions and I argue instead that the activity (...) of MNs in an observer’s brain is enhanced by a prior representation of the agent’s intention and that their task is to predictively compute the best motor command suitable to satisfy the agent’s intention.

In this essay we will argue for the following theses: 1- know-how is not a form of practical knowledge devoid of propositional sense; 2- the relationship between each perception and the body itself is metaphysically contingent. 3- it is up to the brain to configure or to shape a physical body (Körper) into a living body (Leib) and not the other way around; 4- phenomenal externalism of enactivist nature, even in its mild form, is empirically implausible: the correlation between the (...) conscious character of sensory experience with spatiotemporal neuronal patterns is much more systematic and regular than with anything outside the brain. But in its radical form is entirely implausible and contra-intuitive: phenomenal duplicates are not necessarily duplicates of agency; in short, 5-we are our own brain that has a body, avatars, and artifacts, properly configured and molded by the brain, and not a body that has a brain among other essential organs.

In this paper we secure the explanatory value of affordances by treating them as relational properties and as inherently linked to unintentional movements and possible intentional actions. We distinguish between Basic affordances, which are related to unintentional movements, and Complex affordances, which are subjective and executively controlled by individuals. The linkage between affordances and motor intentions allows for accounting for the infinite number of affordances that any given object potentially has. Appealing to objective systematic contingencies that provide the actor with (...) information about the effects of her actions, allows for accounting for perception of affordances and for securing their explanatory value.

The tuning-fork model of human social cognition, based on the discovery of mirror neurons (MNs) in the ventral premotor cortex of monkeys, involves the four following assumptions: (1) mirroring processes are processes of resonance or simulation. (2) They can be motor or non-motor. (3) Processes of motor mirroring (or action-mirroring), exemplified by the activity of MNs, constitute instances of third-person mindreading, whereby an observer represents the agent's intention. (4) Non-motor mirroring processes enable humans to represent others' emotions. After questioning all (...) four assumptions, I point out that MNs in an observer's brain could not synchronically resonate with MNs in an agent's brain unless they discharged in a single brain in two distinct tasks at different times. Finally, I sketch a conceptualist alternative to the resonance model according to which a brain mechanism active in both the execution and the perception of e.g., the act of grasping is the neural basis of the concept of e.g., grasping.
