This a review of Alva Noë's Action in Perception. It argues that a distinction should be made between the proposition that sensorimotor feedback is used in sensory perception and that perception is of sensorimotor features of the world. Noë fails to make this distinction.

A comparison of disjunctive theories of action and perception. The development of a theory of action that warrants the name, a disjunctive theory. On this theory, there is an exclusive disjunction: either an action or an event (in one sense). It follows that in that sense basic actions do not have events intrinsic to them.

Certain empirical results suggest a way of challenging two natural and widespread assumptions about the mind. One assumption is about the relations between perception and action. This shows up in the widespread conception of perception and action in terms of input and output, respectively. Perception is conceived as input from world to mind and action is conceived as output from mind to world. The other assumption is about the relations between mind and world. It influences various opposed views about whether the contents of the mind are in principle independent of the outside world.

Within cognitive science, language is often set apart (as it is in the present volume) from perception, action, learning, memory, concepts, and reasoning. Yet language is intertwined with all of them. Language perception is a kind of perception; language production is a kind of action. Vocabulary and grammar are learned and stored in long-term memory. As novel utterances are perceived or produced, they are built up in working memory. Concepts are most often studied in the context of word meanings; reasoning is most often studied in the context of inferring one sentence from another.

* Fascinating topic in the philosophy of mind and action * Changes the focus of, and gives fresh momentum to, current discussions of self-identification and self-reference * Rigorous discussion of rival views Lucy OBrien argues that a satisfactory account of first-person reference and self-knowledge needs to concentrate on our nature as agents. She considers two main questions. First, what account of first-person reference can we give that respects the guaranteed nature of such reference? Second, what account can we give of our knowledge of our mental and physical actions? Clearly written, with rigorous discussion of rival views, this book will be of interest to anyone working in the philosophy of mind and action.

A traditional view of perception and action makestwo assumptions: that the causal flow betweenperception and action is primarily linear or one-way,and that they are merely instrumentally related toeach other, so that each is a means to the other.Either or both of these assumptions can be rejected.Behaviorism rejects the instrumental but not theone-way aspect of the traditional view, thus leavingitself open to charges of verificationism. Ecologicalviews reject the one-way aspect but not theinstrumental aspect of the traditional view, so thatperception and action are seen as instrumentallyinterdependent. It is argued here that a betteralternative is to reject both assumptions, resultingin a two-level interdependence view in whichperception and action co-depend on dynamicallycircular subpersonal relations and as a result may bemore than merely instrumentally interdependent. Thisis illustrated by reference to motor theories ofperception and control theories of action.

Theories that make action central to perception are plausible, though largely untried, for space perception. However, explaining object recognition, and high-level perception generally, will require reference to representations of the world in some form. Nonetheless, action is central to cognition, and explaining high-level perception will be aided by integrating an understanding of action with other aspects of perception.
