Carvath The empirical status of psychoanalytic theory will be considered in terms of the following questions: (1) Is psychoanalytic theory testable? (2) If so, how much of it is testable, and, in particu- lar, what parts? (3) How is it testable (clinically? experimen- tally? epidemiologically?)? (4) How much of psychoanalytic theory has actually been tested in these ways, and was the theory sup- ported by the evidence? (5) Are future tests of psychoanalytic theory likely to yield outcomes that support the theory, and is this theory the best one to use to guide future research? (6) Is the proportion of psychoanalytic theory that is testable compar- able to the proportions of other scientific theories that are te- stable, or is evidence disproportionately remote from or ir- relevant to psychoanalytic theory? (7) Is testability irrelevant to some kinds of theoretical understanding? (8) Is psychoanalytic theory based on adequate views of conscious and unconscious processes and explanation? These questions will be discussed by clinicians, experimentalists and methodologists of science. THE VALIDITY OF HIDDEN MOTIVES IN PSYCHOANALYTIC THEORY (A.

Matthews) _________________________________________________________________ Wednesday 15 May: 2pm - 5pm Symposium: "Unconscious Processing" Chairman: P. Kolers It is undeniable that most cerebral information processing is un- conscious. Not only are vegetative functions such as posture and respiration (as well as automatized, overlearned skills) uncons- ciously controlled by the brain, but even the basic processes underlying higher cognitive activity are unavailable to conscious introspection: No one knows "how" he actually adds two and two, retrieves a name, recognizes a face. This is what makes cognitive modeling a nontrivial enterprise. But apart from these basic cog- nitive processes (about which our ignorance is sufficient to demonstrate that that they are not conscious), there are some kinds of processes that are at least normally accompanied by some awareness of their occurrence. These include the detection, discrimination and identification of verbal and perceptual in- puts. New data indicate that even these activities may sometimes occur without introspective awareness of their occurrence. This new look at "subliminal perception" and related phenomena in a contemporary psychophysical, information processing framework will examine the evidence, methodological criteria and theoreti- cal interpretations of the newer findings.

Forgerson) _________________________________________________________________ Wednesday 15 May: 7pm - 10pm Symposium: "Paradoxical Neurological States" Chairman: R. Puccetti This symposium will consider neurological states that (based on their symptoms and inferences from their symptoms) are very hard to imagine "being in." These include: (1) "blindsight," i.e., the loss of all conscious visual experience, but with the retention of "visual" information (e.g., object location); (2) the anosag- nosias and attentional disorders, i.e., the apparent unawareness and denial of dramatic neurological deficits such as loss of large portions of the visual field or of body sensation; (3) deconnection phenomena such as alexia without agraphia (intact vision with the loss of all ability to read but the retention of the ability to write) or the split-brain patient's ability to match but inability to name out-of-sight objects grasped with the left hand; (4) various memory disorders such as the ability to acquire cognitive information and skills with complete inability to remember the episodes in which they were acquired; (5) confabulations arising from these paradoxical states (i.e., the unusual way patients rationalize having these deficits). The clinical phenomenology of these paradoxical states will be described and then they will be discussed in terms of current philosophical, psychological and neurological theories of cognition and consciousness.

Millikan ("Back Before Aardvark") _________________________________________________________________ Thursday 16 May: 9am - 12 noon Symposium: "Category Formation - II" Chairman: G. Hirst Categorization is a fundamental human activity. It is involved in everything from operant discrimination to perceptual recognition to naming to describing. Five different approaches to categori- zation now exist more or less in parallel: (1) The nativist ap- proach, which holds that there are few, if any, nontrivial induc- tive categories, and hence that most categories are preformed (2) the statistical pattern recognition and multidimensional scaling approach, which computer-models category formation probabilistically; (3) the artificial intelligence ap- proach, which models categorization with symbol-manipulation rules; (4) the natural category approach, which investigates categorization through reaction time studies and typicality judg- ments and developmentally; (5) the categorical perception ap- proach, which investigates categorization through discrimination and identification studies. These approaches will be presented and the interaction will aim at a synthesis. CATEGORICAL PERCEPTION, CATEGORY INDUCTION AND CATEGORY REPRESEN- TATION (S. Harnad) INDEXING AND LEARNING (R. Schank) ON THE EXISTENCE, NATURE AND PLASTICITY OF PERCEPTUAL CATEGORIES (N. Macmillan) Discussants: M. Lipton, G. Matthews, D. Young _________________________________________________________________ Thursday 16 May: 2pm - 5pm Workshop I: "Artificial Intelligence Versus Neural Modeling In Psychological Theory" Chairman: J. Barnden The issues will be discussed at two levels, a practical one (P) and a foundational one (F). At the practical level the following two questions will be considered: (P1) Is psychological theory- building more successful with or without constraints from neuros- cientific evidence and neuroscientific considerations? (P2) Are the current differences between models that are neurally motivat- ed (which tend to be statistical, connectionistic, and lately, parallel) and models that are not neurally motivated (which tend to be symbol/sentence manipulative) fundamental differences, and is one approach more promising than the other? At the foundational level the questions will be: (F1) What are the data that psychological theory should account for (behavioral performance? cognitive competence? real-time topography and exe- cution? neural activity?)? (F2) Is a successful functional theory of higher cognitive performance and competence necessarily "implementation-independent" (i.e., independent of the architec- ture of the mechanism that embodies it)? Tne issues will be dis- cussed in the context of actual current work in modeling. ARCHITECTURAL LEVELS, SYMBOLS AND SUCH-LIKE THINGS (A. Newell) EPISTEMOLOGY AND THE NEW CONNECTIONISM (A.

Schank ---------- Thursday 16 May: 7pm - 10pm Workshop II: "AI vs. NM" (continuation of Workshop I) Chairman: W. Seager (see Workshop I) _________________________________________________________________ Friday 17 May: 9am - 12 noon Symposium: "Memory and Consciousness" Chairman: R. Lockhart The symposium will examine the distinction between memory (the consequence of some experience) and remembering (the awareness of past events), which involves consciousness of a past experience. The distinction involves the relation between mental processes that reasonably decribe the performance of intelligent systems (whether animals, people or machines), that is, "subpersonal" cognitive psychology, and the intentional mental activities and states of conscious human adults: "intentional psychology."

Barnden) __________________________________________________________________ Friday 17 May: 2pm - 5pm Symposium: "The Reality of the 'G' (General) Factor in the Measurent and Modeling of Cognitive Capacity" Chairman: P. Hertzberg When intelligence tests are factor-analyzed (i.e., the structure of their correlations with one another is reduced to a small number of underlying variables), one general, overall factor al- ways emerges, along with a number of special factors peculiar to some groups of tests and not others. The general ("g") factor has been interpreted as a unitary measure of general intelligence. Some have challenged the reality of "g" on the grounds that indi- vidual test items (and indeed entire tests) are so constructed as to correlate with one another, and hence the overall positive correlation factor is built in; moreover, it is argued that it is fallacious to think in terms of an underlying, one-dimensional unitary intelligence. Others have argued that "g" is an empirical finding after all, because even tests constructed and validated to measure the special abilities (e.g., verbal versus spatial skills) have high "g" loadings, and indeed the more discriminat- ing tests (the ones that are more sensitive to and predictive of individual differences) tend to have the higher "g" loadings. The technical and conceptual problems of measuring, validating and modeling human cognitive capacities will be discussed in the con- text of the interpretation of "g."

Dretske (president-elect) REDUCTIONISM IN THE INVESTIGATION OF CONSCIOUSNESS P. S. Churchland (president, SPP) _________________________________________________________________ Saturday 18 May: 9am - 12 noon Symposium: New Directions in Evolutionary Theory Chairman: A. Jensen Among the current developments in evolutionary theory and their implications for psychology that will be discussed are: (1) The "new preformationism," arising chiefly from develomental biology, according to which there are substantial structural constraints on the variation on which selection can operate; this implies that there are structures and functions that cannot be regarded as having been shaped by random variation and selection by conse- quences but rather as having arisen from boundary conditions on biological structures. The issue is particularlly relevant to questions about the origins of cognitive and linguistic struc- tures. (2) Current sociobiological theory has be- come concerned with cognitive questions, in particular, the ex- istence of "cognitive primitives" on which selection would operate in a way that is analogous to its effects on traits coded by genes: Is this "gene-culture co-evolution" and its new unit, the "culturgen" just overinclusive curve-fitting or is there a real empirical phenomenon here? (3) In general, are the kinds of assumptions and inclusive-fitness calculations that characterize sociobiological theorizing (and that have been critically re- ferred to as "just-so stories") a reasonable explanatory handicap or signs of taking the wrong theoretical direction? In particu- lar, when is a conscious, cognitive explanation of a behavior preferable to an unconscious, fitness-related one? THE NEW PREFORMATIONISM: AN EMBRYOLOGIST'S PERSPECTIVE (E. Balon; discussant: M. Ruse) METHODOLOGICAL BEHAVIORISM, EVOLUTION AND GAME THEORY (E. Sober; discussant: A. Rapoport) EVOLUTIONARY VERSUS COGNITIVE EXPLANATIONS OF CRIME AND PUNISH- MENT: A FALSE DICHOTOMY (W. Shields; discussant: A. Rosenberg) ------------------------------ (Parallel) Symposium: "Psychology, Pictures and Drawing" Chairman: W. Savage The past decade has seen considerable interest in theory of dep- iction and allied theories of drawing. Current theories are technically well constructed, significant in themselves and, in addition, have important implications for neighboring areas of psychology. Yet they are often distinct in the assumptions they make about perception, communication and the environment. The present symposium draws together philosophers, educators and psychologists who have developed theories about pictures, percep- tion and drawing. Assumptions will be reviewed and implications will be discussed. PRODUCTION PROCESSES FOR DRAWING: FUNCTIONAL UNITS OF INFORMATION PROCESSING (J. Caron-Pargue) A NEOSTRUCTURALIST ANALYSIS OF DRAWING DEVELOPMENT (S. Dennis) MENTALISM AND PICTURES: THE POWERS OF ELEMENTS, CHOICES OVER GEOMETRIES AND PICTORIAL METAPHORS (J.M.

Willats) Discussants: S. Brison, D. Pariser _________________________________________________________________ Saturday 18 May: 2pm - 5pm Symposium: "The Scientific Status of Parapsychological Research" Chairman: I. P. Howard In parapsychology there appears to be a chronic polarization of rival views in a way that only occurs occasionally and briefly at the frontiers of other kinds of scientific research. The polari- zation consists of those who accept the validity of the reported phenomena and of the theoretical framework accounting for them and those who do not. The following questions will be considered: (1) Is the polarization merely a prejudice, or are there objec- tive characteristics that set this field of research apart? (2) Are there special problems with furnishing replicable positive evidence in this area? (3) Are there logical problems with the theoretical framework in which the research is undertaken? (4) Are there statistical problems with the data-analysis and the underlying assumptions? (5) Is there any possibility of resolu- tion, or will the field always continue to split among believers and nonbelievers, and if the latter, (6) what does that imply about the scientific validity of this domain of inquiry? These questions will be discussed, in the context of representative current experimental work in parapsychological research, by parapsychologists, skeptics and (as yet) uncommitted methodolo- gists. THE MANIFESTATIONS OF BIAS IN CRITICISM OF PARAPSYCHOLOGY (R. L. Morris) PARAPSYCHOLOGY: WHERE IS THE PHENOMENON ABOUT WHICH TO BUILD A SCIENCE? (J.E. Alcock) AN EXPERIMENTALIST'S PERSPECTIVE ON THE RESOLUTION OF THE PSI CONTROVERSY (C. Honorton) Discussants: K. Emmett, R. Hyman, M. Truzzi ------------------------------ (Parallel) Symposium: "The Ascription of Knowledge States to Children: Seeing, Believing and Knowing Chairman: TBA Considerable discussion in cognitive science surrounds the issue of the ascription of beliefs to animals, machines and young chil- dren. Opinions range from that of Davidson, who argues that one cannot have beliefs unless one has a concept of belief, to that of Searle, who argues that "only someone in the grip of a philo- sophical theory would deny that dogs and children have beliefs." Recent research on children's ascription of beliefs to others and to themselves in the interpretation of visual events may cast some light on this question.

Kuczaj _________________________________________________________________ Saturday 18 May: 7pm - 10pm Symposium: "Interpretation Versus Explanation in Cognitive and Social Theory" Chairman: A. Grunbaum The following questions will be considered: (1) What is an expla- nation, and is "scientific" explanation an atypical case or a paradigmatic one? (2) What is the role of testability and falsi- fiability in explanation? (3) What is the role of considerations of satisfyingness, coherence, elegance and other subjective cri- teria in explanation? (4) Are there different explanatory metho- dologies in the natural sciences and ther "human" sciences? (5) Is there an objective way to choose among rival interpretations? (Should there be? Is there one in the case of rival scientific theories?) (6) Is there anything objective to replace the outmod- ed "positivistic" stereotype? Pro and antihermeneuticists will participate and the discussion will focus on the role of in- terpretation in psychological and social scientific theory. TOWARDS AN INTERPRETIVE PSYCHOLOGY (E.V.
