Challenging and rewarding in equal measure, _Phenomenology of Perception_ is Merleau-Ponty's most famous work. Impressive in both scope and imagination, it uses the example of perception to return the body to the forefront of philosophy for the first time since Plato. Drawing on case studies such as brain-damaged patients from the First World War, Merleau-Ponty brilliantly shows how the body plays a crucial role not only in perception but in speech, sexuality and our relation to others.

Ethologists and others studying animal behavior in a spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable data - is sketched. The (...) underlying assumptions of this approach can be seen to ally it directly with theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the Their arguments, which are strongly analogous to B. F, Skinner's arguments against point to certain pitfalls that attend the careless exercise of such thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.

This paper concerns how motor actions are neurally represented and coded. Action planning and motor preparation can be studied using a specific type of representational activity, motor imagery. A close functional equivalence between motor imagery and motor preparation is suggested by the positive effects of imagining movements on motor learning, the similarity between the neural structures involved, and the similar physiological correlates observed in both imaging and preparing. The content of motor representations can be inferred from motor images at a (...) macroscopic level, based on global aspects of the action (the duration and amount of effort involved) and the motor rules and constraints which predict the spatial path and kinematics of movements. A more microscopic neural account calls for a representation of object-oriented action. Object attributes are processed in different neural pathways depending on the kind of task the subject is performing. During object-oriented action, a pragmatic representation is activated in which object affordances are transformed into specific motor schemas (independently of other tasks such as object recognition). Animal as well as human clinical data implicate the posterior parietal and premotor cortical areas in schema instantiation. A mechanism is proposed that is able to encode the desired goal of the action and is applicable to different levels of representational organization. (shrink)

As adults we believe that our knowledge of our own psychological states is substantially different from our knowledge of the psychological states of others: First-person knowledge comes directly from experience, but third-person knowledge involves inference. Developmental evidence suggests otherwise. Many 3-year-old children are consistently wrong in reporting some of their own immediately past psychological states and show similar difficulties reporting the psychological states of others. At about age 4 there is an important developmental shift to a representational model of the (...) mind. This affects children's understanding of their own minds as well as the minds of others. Our sense that our perception of our own minds is direct may be analogous to many cases where expertise provides an illusion of direct perception. These empirical findings have important implications for debates about the foundations of cognitive science. (shrink)

A representation is a remnant of previous experience that allows that experience to affect later behavior. This paper develops a metatheoretical view of representation and applies it to issues concerning representation in animals. To describe a representational system one must specify the following: thedomainor range of situations in the represented world to which the system applies; thecontentor set of features encoded and preserved by the system; thecodeor transformational rules relating features of the representation to the corresponding features of the represented (...) world; themedium, or the representation's physical instantiation; and thedynamics, or how the system changes with time. In part because of the behaviorist assumption that the hypothetical, covert changes occurring in an organism during learning correspond to the overt physical changes that are observed, issues of representation in animal behavior have been largely ignored as irrelevant or misleading. However, it can be inferred that representations, acting as models of environmental regularities, operate at many levels of behavioral functioning, both cognitive and noncognitive. Objections to the use of this concept in explanations of animal behavior, based on the claim that it is indeterminate and on behaviorist considerations of parsimony, can be answered. Animal representations may be specialized in terms of tasks and species. Data from tasks involving spatial memory, delayed matching-to-sample, and sequence learning suggest some foundations for a general theory of animal representations. (shrink)

I address the commentators' calls for clarification of theoretical terms, discussion of similarities to other proposals, and extension of the ideas. In doing so, I keep the focus on the purpose of memory: enabling the organism to make sense of its environment so that it can take action appropriate to constraints resulting from the physical, personal, social, and cultural situations.

This article presents an interpretation of Merleau-Ponty's notion of pre-reflective intentionality, explicating the similarities and differences between his and Husserl's understandings of intentionality. The main difference is located in Merleau-Ponty's critique of Husserl's noesis-noema structure. Merleau-Ponty seems to claim that there can be intentional acts which are not of or about anything specific. He defines intentionality by its ``directedness'', which is described as a bodily, concrete spatial motility. Merleau-Ponty's understanding of intentionality is part of his attempt to rewrite the relation (...) between the universal and the particular. He claims that meaning is intrinsic to the phenomenal field and impossible to analyse by a distinction between form and matter. Still, Merleau-Ponty's notion of meaning and philosophy is strictly opposed to any naturalized philosophy. This becomes explicated at the end of the article, where his attempt to embody intentionality is compared to Daniel Dennett's corresponding approach. (shrink)

Corresponding to Glenberg's distinction between the automatic and effortful modes of memory, I propose a distinction between cued and detached mental representations. A cued representation stands for something that is present in the external situation of the representing organism, while a detached representation stands for objects or events that are not present in the current situation. This distinction is important for understanding the role of memory in different cognitive functions like planning and pretense.

The brain is not silent. Even in the absence of stimuli are the neurons activated every now and then in what is called "spontaneous" or "background activity" which provides a noisy background to the operation of the brain. This work shows how this noise can be utilized in the cognitive process. That is, rather than being treated as a nuisance, noise is given a functional role in the brain´s activity. More than this, the role noise is given is a very (...) essential one. In fact, the models presented in this work would not function without it. The utilization of spontaneous activity is demonstrated in two ways. First, it is shown how this activity can enable new knowledge to be assimilated by the system. This ability is described using a framework of generalised evolution that permits cognition to be considered as an evolutionary process occurring within the life-time of the individual. In this evolutionary view of cognition, the spontaneous activity provides the mechanism of variation. This mechanism of variation is very simple in its nature. Yet, its effects are able to follow the growth of an ever more complex cognitive apparatus as it evolves in the individual mind. The second demonstration of the utilization of noise is a novel model of how the brain is able to detect visual motion. The utilization of spontaneous activity significantly reduces the complexity of the model compared to traditional approaches. The model presented here makes the basic assumption that motion that are present in the current scene was already detected in the previous scene. That is, all that the model needs to do is to update the previous detection to fit the current scene. To account for the initial detection of a movement, spontaneous activity is utilized. Any motion in the visual scene is assimilated by the process if it harmonises with this background activity. Thus, the operation of the system is dependent on the presence of noise. Just like the case of knowledge acquisition mentioned above, noise is used to assimilate new structures into the system. (shrink)
