In The Rediscovery of the Mind , John Searle offers a novel theory of consciousness that attempts to overcome the traditional debates within the philosophy of mind between dualism and materialism. Searle maintains that one can be a thoroughgoing materialist without denying the existence of mental phenomena that are inherently subjective in nature. In this paper I argue that Searle's view does not so easily bypass the traditional philosophical debate between materialism and dualism, and, indeed, that Searle's attempt to have it both ways is inconsistent. More specifically, I examine Searle's discussion of the causal reducibility of consciousness and his claim that consciousness is just another property of certain biological systems and argue that in both cases Searle has failed to show that consciousness can be both irreducibly subjective and a normal physical feature of the brain.  相似文献

A microcomputer-assisted system that permits multiple events to be coded from videotape to a common time base is described. The system allows an operator, by pressing a button, to record the onset and offset times of any number of events. It requires a video recorder, an Apple II microcomputer, a John Bell 6522 timing card, and a pair of switches. The software package consists of five programs: one to make timing signals on the videotape, one to record the onset time and duration of the operator’s buttonpresses, one to read and print the coding data from disk, one to operate the timer, and one to process the compiled code used in the software package. All necessary wiring diagrams are shown. Software is available gratis from the authors on request.  相似文献

Several points in the original article by Palmer and Rock (1994) are clarified in light of Peterson’s (1994) commentary. First, we address several issues related to the nature and order of organizational processes in our theory. We argue that many of her objections result from misconceptions about our theory. We attempt to clarify the relevant issues, including the fact that we intended the theory to describe an ordering of processes in cascade rather than as a sequence of classical discrete stages. Second, we discuss Peterson’s objections to our discussion of her findings on the relation between figure-ground processing and object recognition. We argue against her “prefigural recognition” proposal on logical grounds and provide an alternative account of her findings in terms of our theory.  相似文献

Contingencies of selection, be they phylogenetic or ontogenetic, merely set boundaries on units; they do not provide blueprints. Thus, variability is fundamental to all products of selection. Skinner, by characterizing the units of analysis in behavior as generic in nature, established his science squarely within the selectionist paradigm, thereby avoiding the tendency, common throughout psychology, to slip into essentialist analyses. The distinction between essentialism and selectionism is refined in this article, and prominent examples of essentialism in linguistics, theories of memory, theories of representation, associationism, and even in behavior analysis are identified. Recent trends in cognitive science--specifically, research on adaptive networks--is amenable to a selectionist interpretation, suggesting the possibility of future fruitful interactions with behavior analysis.  相似文献

A small clinical survey was undertaken at East Carolina University School of Medicine to examine the factors which influenced the decisions of five families to continue pregnancies after a chromosomal abnormality was detected. Little has been published concerning the psychosocial effects after continuing pregnancies in which the fetus was diagnosed with a chromosome abnormality by amniocentesis. In order to identify the factors that influenced their decisions, an interview with each couple was undertaken using a 25-part questionnaire. This paper addresses the method of interviewing, case material, and background concerning each couple and the summary of the results.  相似文献

A selectionist approach to reinforcement.   总被引:3,自引:3,他引:0       下载免费PDF全文
We describe a principle of reinforcement that draws upon experimental analyses of both behavior and the neurosciences. Some of the implications of this principle for the interpretation of behavior are explored using computer simulations of adaptive neural networks. The simulations indicate that a single reinforcement principle, implemented in a biologically plausible neural network, is competent to produce as its cumulative product networks that can mediate a substantial number of the phenomena generated by respondent and operant contingencies. These include acquisition, extinction, reacquisition, conditioned reinforcement, and stimulus-control phenomena such as blocking and stimulus discrimination. The characteristics of the environment-behavior relations selected by the action of reinforcement on the connectivity of the network are consistent with behavior-analytic formulations: Operants are not elicited but, instead, the network permits them to be guided by the environment. Moreover, the guidance of behavior is context dependent, with the pathways activated by a stimulus determined in part by what other stimuli are acting on the network at that moment. In keeping with a selectionist approach to complexity, the cumulative effects of relatively simple reinforcement processes give promise of simulating the complex behavior of living organisms when acting upon adaptive neural networks.  相似文献

Near-point and far-point binocular and monocular sighting tests given 20 high and 20 low achievers each from regular classrooms at Grades 4, 8, and 12 (N = 240) yielded significant chi 2 for differences of proportions of lateral agreement with sidedness in comparison to distributions unrelated to sidedness. Composite sighting congruent to sidedness yielded significant differences between classroom and reading clinic samples. The near-point binocular sighting test markedly influences distributions of combined scores in sighting.  相似文献

Role-play generalization of newly acquired assertive behavior was assessed across different response situations in a clinical outpatient sample. Prior to assertive training, subjects completed two paper-and-pencil inventories and a series of role-play situations. Behavioral role-play scenes included four response forms: making requests, expressing affection, standing up for rights, and expressing displeasure. Subjects were randomly assigned to treatment or test-retest conditions and the treatment subjects received six 2-hr sessions of assertion training using modeling, behavior rehearsal, instruction, positive reinforcement, assignedin vivo homework, bibliotherapy, and daily recordings of assertive behavior. Posttreatment, subjects completed the paper-and-pencil measures, trained role-play scenes, and a set of dissimilar untrained scenes requiring different response forms (giving compliments, receiving compliments; refusing unreasonable requests and expressing justified anger). Videotapes were rated blindly and in random order at the conclusion of the study by trained judges. Treatment and test-retest subjects were equivalent prior to training. Posttreatment for the two groups differed in self-report, role-play behavior in trained situations, and role-play behavior in untrained dissimilar situations (allp<.001). MANOVA with repeated measures confirmed that trained and generalization role-play scenes were quantitatively, as well as qualitatively, different, confirmed that treatment and test-retest subjects exhibited different performance levels posttreatment on both trained and generalization scenes, and revealed four significant interactions (allp<.001). Implications of the interactions are discussed. Canonical correlation revealed that subjects displayed significant commonality in their behavioral profiles across different response forms. The findings indicate that complex training resulted in generalization from trained situations to untrained and dissimilar generalization scenes for the clinical outpatient sample.  相似文献

Abstract

This study presents the development of the Idiographic Functional Status Assessment (IFSA), an interview to assess functional status according to each person's unique point of view. This idiographic method asks people to state their personal goals in terms of things they want to accomplish, problems they want to solve, situations they hope to avoid, roles and relationships they want to maintain, and pursuits they want to relinquish. After describing their goals, respondents rate goal attainment activities they have pursued in the past month in terms of level of difficulty, dependence and other performance dimensions. In a study of 224 people with AIDS, the idiographic measure provided functional status scales that were relatively stable over time, and that correlated well with other subjective well-being measures and heath status criteria. Goal content measures derived from the interview can be used to distinguish sub samples that differ in terms of the determinants of quality of life.  相似文献
