This first volume contains discussions of the brain, methods for analyzing behavior, thought, consciousness, attention, association, time, and memory.

Since the advent of behaviorism the question of volition or "will" has been largely neglected. We consider evidence indicating that two identical behaviors may be quite distinct with respect to volition: For instance, with practice the details of predictable actions become less and less voluntary, even if the behavior itself does not visibly change. Likewise, people can voluntarily imitate involuntary slips they have just made. Such examples suggest that the concept of volition applies not to visible behavior per se, but (...) to the control system that guides behavior. Involuntary events include both automatisms and counter voluntary actions such as slips . An adequate theory of voluntary control must account for the entire set of such pairs of voluntary/involuntary contrasts. The problem of volition highlights core psychological issues. Voluntary acts are consistent with one′s current dominant goals. Volition and consciousness are intimately related. Consciousness of an action seems to recruit unconscious resources that help in planning, executing, and monitoring a voluntary act. Conversely, losing conscious access to an action seems to produce a loss of voluntary control. However, voluntary actions are not wholly conscious. It appears that we only need conscious access to nonroutine choice-points in the flow of control; routine aspects are handled unconsciously. The goals that guide voluntary acts often encounter conflict, either from reality or from other goals, and emotions are widely believed to result from appraisals of such conflicts . Finally, there is a close connection between countervoluntary slips and the symptoms of clinical pathology, which involve a loss of voluntary control over speech, action, feeling, imagery, or thought. A modern version of William James′ ideomotor theory is proposed, based on Global Workspace theory . The theory shows how a conscious goal image could activate unconscious plans and automatisms that shape a voluntary act. Conscious feedback from the act serves to communicate success or failure to many unconscious routines, which may then adapt cooperatively to shape future actions. (shrink)

Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones - such as (...) stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

Having laid the groundwork in his critically acclaimed books Neural Darwinism (Basic Books, 1987) and Topobiology (Basic Books, 1988), Nobel laureate Gerald M. Edelman now proposes a comprehensive theory of consciousness in The Remembered ...

The theory of visual perception that Irvin Rock develops and supports in this book with numerous original experiments, views perception as the outcome of a process of unconscious inference, problem solving, and the building of structural descriptions of the external world.

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

Describes the various senses as sensory systems that are attuned to the environment. Develops the notion of rich sensory information that specifies the distal environment. Includes a discussion of affordances.

[opening paragraph] -- Clark: The `astonishing hypothesis' which you put forward in your book, and which you obviously feel is very controversial, is that `You, your joys and sorrows, your memories and ambitions, your sense of personal identity and free will are, in fact, no more than the behaviour of a vast assembly of nerve cells. As Lewis Carroll's Alice might have phrased it: `You're nothing but a pack of neurons'.' But it seems to me that this is not so (...) astonishing a statement for a scientist to make. Isn't this what reductionist science has always believed? (shrink)

Integrates data from various research areas concerned with the effects of unconscious perception and the preconscious antecedents of subjective experience. Discusses the possible nature and origin of preconscious processes, the evidence for unconscious perception, and the effects of unperceived stimuli on perception, verbal behavior, and memory. Examines the theory that cognitive processes evolved for the gratification of need.

The well-known behaviorist revolt against consciousness is largely in the past, although that does not mean that the new interest in consciousness is without many unsolved problems. Cognitive psychology, as an alternative, is not necessarily a consciousness psychology, and humanistic psychology, friendly to consciousness, has difficulty in maintaining scientific status. One approach to consciousness is by way of dissociation, the phenomena of which can be found in everyday experience but can be studied in more detail through hypnosis. One aspect of (...) hypnosis research has led to the concept of a “hidden observer,” a metaphor used to indicate that some information is processed and has consequences without being in the focus of consciousness at the time, but is recoverable through hypnosis. The evidence comes mostly from subjects highly responsive to hypnosis, so that generalizations must be used with caution. The divisions of consciousness lead to consideration of its executive and monitoring functions-normal functions, but subject to some alterations through hypnosis. (shrink)

Evidence and theory ranging from traditional philosophy to contemporary cognitive research support the hypothesis that consciousness has a two-part structure: a focused region of articulated experience surrounded by a field of relatively unarticulated, vague experience.William James developed an especially useful phenomenological analysis of this "fringe" of consciousness, but its relation to, and potential value for, the study of cognition has not been explored. I propose strengthening James′ work on the fringe with a functional analysis: fringe experiences work to radically condense (...) context information in consciousness; are vague because a more explicit representation of context information would overwhelm consciousness′ limited articulation capacity; help mediate retrieval functions in consciousness; and contain a subset of monitoring and control experiences that cannot be elaborated in focal attention and are "ineffable." In general, the phenomenology of the fringe is a consequence of its cognitive functions, constrained by consciousness′ limited articulation capacity. Crucial to monitoring and control is the feeling of "rightness." Rightness functions as a summary index of cognitive integration, representing, in the fringe, the degree of positive fit between a given conscious content and its parallel, unconsciously encoded context. Rightness appears analogous to the connectionist metric of global network integration, known variously as goodness-of-fit, harmony, or minimum energy. (shrink)

A broad consensus has developed in recent years in the cognitive and neurosciences that the cognitive functions of the mind arise out of the activities of an extensive and diverse array of specialized processors operating as a parallel, distributed system. A theoretical perspective is presented which expands upon this "society" model to include globally integrative infuences upon this arrary of processors. This perspective serves as the basis for an explicit neural model of a "global workspace within a system of distributed (...) specialized processors". Anatomical and physiological evidence are reviewed which suggest that this parallel, modular architecture is superceded by a more diffuse, tangential intracortical network capable of integrating underlying modular activites into increasingly global cognitive representations. There follows an explication of the role of this "neural global workspace" in providing the essential basis for the central control of attention and the generation of unified, conscious percepts. Finally the role of thalamic and brainstem activation systems in these integrative processes is discussed. (shrink)
