The Modularity of Mind proposes an alternative to the or view of cognitive architecture that has dominated several decades of cognitive science. Whereas interactionism stresses the continuity of perceptual and cognitive processes, modularity theory argues for their distinctness. It is argued, in particular, that the apparent plausibility of New Look theorizing derives from the failure to distinguish between the (correct) claim that perceptual processes are inferential and the (dubious) claim that they are unencapsidated, that is, that they are arbitrarily sensitive (...) to the organism's beliefs and desires. In fact, according to modularity theory, perceptual processes are computationally isolated from much of the background knowledge to which cognitive processes have access. The postulation of autonomous, domain-specific psychological mechanisms underlying perceptual integration connects modularity theory with the tradition of faculty psychology, in particular, with the work of Franz Joseph Call. Some of these historical affinities, and some of the relations between faculty psychology and Cartesianism, are discussed in the book. (shrink)

This paper takes an integrated history and philosophy of science approach to the topic of "simplicity out of complexity". The reflex theory was a framework within early twentieth century psychology and neuroscience which aimed to decompose complex behaviours and neural responses into simple reflexes. It was controversial in its time, and did not live up to its own theoretical and empirical ambitions. Examination of this episode poses important questions about the limitations of simplifying strategies, and the relationship between simplification and (...) the engineering approach to biology.

in april 1933, two bright young Ph.D.s were elected to the Harvard Society of Fellows: the psychologist B. F. Skinner and the philosopher/logician W. V. Quine. Both men would become among the most influential scholars of their time; Skinner leads the "Top 100 Most Eminent Psychologists of the 20th Century," whereas philosophers have selected Quine as the most important Anglophone philosopher after the Second World War.1 At the height of their fame, Skinner and Quine became "Edgar Pierce twins"; the latter (...) obtaining the endowed chair at Harvard's department of philosophy, the former taking up the position at Harvard's psychology department.2Besides these biographical parallels, there also...

An empirical procedure is suggested for testing a model that postulates variables that intervene between observed causes and abserved effects against a model that includes no such postulate. The procedure is applied to two experiments in psychology. One involves a conditioning regimen that leads to response generalization; the other concerns the question of whether chimpanzees have a theory of mind.

A common problem appearing in the discussions is connecting behaviorism with positivism. The main goal of this article is to show that this alliance is not legitimate – main principles of the Skinnerian science rather point to the Mach’s empiricism, pragmatism and operationalism than to Carnap’s project. Secondly it will be shown that behaviorism is most importantly the philosophy of science. In the last part we will consider the main points appearing in the critique of behaviorism and try to give (...) an answer to them. (shrink)

The aim of this essay is a criticism of reductionism ? both in its ?static? interpretation (usually referred to as the layer model or level?picture of science) and in its ?dynamic? interpretation (as a theory of the growth of scientific knowledge), with emphasis on the latter ? from the point of view of Popperian fallibilism and Feyerabendian pluralism, but without being committed to the idiosyncrasies of these standpoints. In both aspects of criticism, the rejection is based on the proposal of (...) a global alternative. Hummell and Opp's research programme for the reduction of sociology to psychology is used as a starting?point and taken as the primary object of criticism. Following the introductory Section I, Section II analyses the three crucial notions of Hummell and Opp's research programme ? their explications of the notions of ?sociology?, ?psychology? and the concept of reduction itself ? and criticizes the authors? deficient ?logic of reduction?. Although the ?local? shortcomings of our authors? ?logic of reduction? do not affect reductionism as such, i.e. logically sound versions of reductionism as devised by Kemeny, Nagel, Oppenheim, Putnam, Woodger et al., it is argued that the logical soundness of sophisticated reductionism cannot compensate for its additional epistemological and methodological deficiencies. Section III analyses the ?dynamic? interpretation of reductionism as a particular developmental pattern of scientific growth. It is argued that even reductionism at its best can produce only cumulative progress, thus ?a priori? excluding scientific revolutions which are inevitably counter?inductive as well as counter?reductive. Section IV discusses the philosophical background of modern reductionism, and examines the effects both of reductionism and of anti?reductionistic pluralism on the autonomy of scientific fields. It is argued that pluralistic anti?reductionism undermines spurious claims for autonomy much more effectively than reductionism. As a ?local? improvement of the reductionistic research programme, the replacement of the predominant one?way reductionism by a less restrictive many?way reductionism is proposed. It is argued that the appropriate treatment for an allegedly backward science (say sociology) is not its reduction to an allegedly more advanced science (say psychology) but its non?reductive replacement by new theories (of the same or of another field) that do not incorporate the older ones. As a ?global? alternative to the reduction of sociology to psychology, the frontier?crossing direct application of psychological theories to sociological phenomena is proposed. A plea is made for a pluralistic science without reduction, based on intra? and interscientific criticism as the proper method for the advancement of knowledge. (shrink)

A reasonable choice between Skinner's and Chomsky's theories requires reference to a conception of human nature. It is explained in detail why this is so, in the context of an analysis of what it is to ‘choose’ a theory. This account helps to explain the unity and coherence of the science, methodology, conception of science, object of scientific inquiry and views towards control of each of Skinner and Chomsky, and thereby explains the chasm which separates the parties to their respective (...) programs. The analysis given implies that, in a precise sense, the theory-choice is implicated in value-judgments. (shrink)

Professor Foxall suggests the radical behaviorist language of contingencies is fine as far as it goes, and is quite suitable for matters of prediction and control. However, he argues that radical behaviorist language is extensional, and that it is necessary to formally incorporate the intentional idiom into the language of behavioral science to promote explanations and interpretations of behavior that are comprehensive in scope. Notwithstanding Professor Foxall's arguments, radical behaviorists hold that the circumstances identified by the use of the intentional (...) idiom are accommodated by the radical behaviorist language of contingencies, not only for prediction and control but also for explanations and interpretations. Of central importance is that individuals may have histories that lead them to generate descriptions of past and present behavior, as well as descriptions of prevailing circumstances that have caused that behavior or are likely to cause that behavior in the future. The resulting verbal behavior may then enter into contingencies influencing their behavior, although the extent to which it does so varies across individuals as a function of their histories. Overall, the way that the pragmatism of radical behaviorism conceives of the nature and contribution of covert events differs appreciably from the way Professor Foxall conceives of the nature and contribution of intentional phenomena.

B. F. Skinner's claim that "operant behavior is essentially the field of purpose" is systematically explored. It is argued that Charles Taylor's illuminating analysis of the explanatory significance of common-sense goal-ascriptions (1) lends some (fairly restricted) support to Skinner's claim, (2) considerably clarifies the conceptual significance of differences between operant and respondent behavior and conditioning, and (3) undercuts influential assertions (e.g., Taylor's) that research programs for behavioristic psychology share a "mechanistic" orientation. A strategy is suggested for assessing the plausibility of (...) Skinner's broader claims about the adequacy of the operant behaviorist program for the analysis of purposive behavior. (shrink)

Understanding how animals might make sense of the interfaces they interact with is important to inform the design of animal-centered interactions. In this regard, biosemiotics provides a useful lens through which to examine animals’ interactions with interfaces and the sensemaking mechanisms that might underpin such interactions. This paper leverages Uexküll’s Umwelt theory, Peirce’s logic of sign relations and Gibson’s theory of affordances to analyze examples of dogs’ interactions with interfaces, particularly the role of the semiotic mechanisms of indexicality and isomorphism. (...) Based on these analyses, the paper derives design implications, and proposes a semiotic framework to support the analysis and design of canine-centered interactions. The framework could be subsequently extended to support the analysis and design of interactive systems for other species. (shrink)
