Catastrophe theory is a new mathematical science that permits some insight into the way in which sudden changes or discontinuities
of behavior may occur even though the underlying causative forces are essentially continuous. This article aims to present
a nonmathematician’s view of catastrophe applications in clinical psychology. Areas covered include anorexia nervosa, binge
eating and drinking, affective disorders, schizophrenia, aggressiveness, and prison disturbances. Where appropriate, therapeutic
implications and possible physiological correlates are offered. Examples are given of catastrophe theory’s ability to explain
previously inexplicable findings. Attention is drawn to its refutability and predictive value, and hence its scientific respectability. 相似文献

Phonology, lexical access in reading, and articulatory suppression: A critical review 总被引:4,自引:0,他引:4
Derek Besner 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1987,39(3):467-478
Considerable confusion exists in the literature on visual word recognition and reading with respect to the effects of articulatory suppression upon phonological recoding. The authors of a large number of journal articles, chapters, cognitive psychology textbooks, and books devoted to reading processes have concluded that suppression interferes with phonological receding of print and have used this supposed fact as a basis for determining when phonology is involved in various reading tasks. Others have concluded that suppression need not interfere with phonological recoding (e.g. Besner, Davies and Daniels, 1981; Besner and Davelaar, 1982). The present review concludes that a phonological code can be derived from printed English and used for lexical access without interference from suppression. However, operations performed upon a phonological code—e.g. post-assembly phonemic segmentation and deletion, maintenance in working memory—are disrupted by suppression. A review of the literature supports this distinction; some implications of these views are noted. 相似文献

The state of health of 135 schizophrenic patients was examined during therapy with a nigrostriatal (Haloperidol) and a mesolimbic (Clozapin) neuroplegic drug, and compared with the situation during treatment without neuroplegics. Among the methods used was the state of health scale of von Zerssen; the neuroleptic threshold was tested using Haase's handwriting test. There was evidence that the patient's health was primarily affected, but individual differential treatment with neuroplegics produced a significant improvement in this important respect. Contrary to Haase, we noticed nothing to convince us of a link between the antipsychotic efficacy of the neuroplegics under investigation and the neuroleptic threshold. 相似文献

The reinforcer pathology model posits that core behavioral economic mechanisms, including delay discounting and behavioral economic demand, underlie adverse health decisions and related clinical disorders. Extensions beyond substance use disorder and obesity, however, are limited. Using a reinforcer pathology framework, this study evaluates medical adherence decisions in patients with multiple sclerosis. Participants completed behavioral economic measures, including delay discounting, probability discounting, and a medication purchase task. A medical decision-making task was also used to evaluate how sensitivity to mild side effect risk and efficacy contributed to the likelihood of taking a hypothetical disease-modifying therapy. Less steep delay discounting and more intense (greater) medication demand were independently associated with greater adherence to the medication decision-making procedure. More generally, the pattern of interrelations between the medication-specific and general behavioral economic metrics was consistent with and contributes to the reinforcer pathology model. Additional research is warranted to expand these models to different populations and health behaviors, including those of a positive health orientation (i.e., medication adherence). 相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise. 相似文献

A widespread view in cognition is that once acquired through extensive practice, mental skills such as reading are automatic. Lexical and semantic analyses of single words are said to be uncontrollable in the sense that they cannot be prevented. Over the past 60 years, apparently convincing support for this assumption has come from hundreds of experiments in which skilled readers have processed an irrelevant word in the Stroop task despite explicit instructions not to, even when so doing would hurt color identification performance. This basic effect was replicated in two experiments, which also showed that a considerable amount of semantic processing is locally controlled by elements of the task. For example, simply coloring a single letter instead of the whole word eliminated the Stroop effect. This outcome flies in the face of any automaticity account in which specified processes cannot be prevented from being set in motion, but it is consistent with the venerable idea that mental set is a powerful determinant of performance. 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献
