For over a decade John Searle's ingenious argument against the possibility of artificial intelligence has held a prominent place in contemporary philosophy. This is not just because of its striking central example and the apparent simplicity of its argument. As its appearance in Scientific American testifies, it is also due to its importance to the wider scientific community. If Searle is right, artificial intelligence in the strict sense, the sense that would claim that mind can be instantiated through a formal program of symbol manipulation, is basically wrong. No set of formal conditions can provide us with the characteristic feature of mind which is the intentionally of its mental contents. Formally regarded, such intentionally is an irreducible primitive. It cannot be analyzed into non-intentional (purely syntactic, symbolic) components. This paper will argue that this objection is based on a misunderstanding. Intentionality is not simply something given which is incapable of further analysis. It only appears so when we mistakenly abstract it from time. When we regard its temporal structure, it shows itself as a rule-governed, synthetic process, one capable of being instantiated both by machines and men. 相似文献

Previous research suggests that one or more of three mediating variables account for the relationships between recruiting sources and applicant effectiveness. This paper offers a critical test of the three mediating variables: demographic characteristics, realistic expectations, and perceived person-job fit. Using a sample of 242 newly hired marketing representatives, the study found that employees recruited through college placement offices had better initial levels of performance than did employees recruited through newspaper advertisements. While all of the proposed mediating variables were associated with some recruitment sources, none of them mediated the effects of recruitment sources on performance or turnover. This paper suggests that there may be complex contingency relationships between recruitment sources and employee performance and turnover. 相似文献

The relationship between gender role identification and decision making orientations was examined. Decision making was analyzed in terms of decision making orientation (behavioral, cognitive, and emotional) and decision making skills (problem definition and formulation, generation of alternative solutions, choice process, solution implementation, and verification). The results revealed a 2-factor characterization of general decision making in terms of approach-avoidance tendencies and self-appraisals of decision skills. A masculinity model was supported for decision making orientation, with masculinity serving as the only significant predictor. In contrast, an androgyny model was supported for decision making skills, with masculinity and femininity serving as significant predictors. 相似文献

Personality and Coping: Three Generations of Research 总被引:1,自引:0,他引:1
ABSTRACT This article introduces the Journal of Personality 's special issue on coping and personality. It first presents a historical overview of the psychological study of how people cope with stress and identifies three generations of theory and research: (a) the psychoanalysts and the ego development school, which tended to equate personality and coping strategies; (b) the transactional approach, which appeared in the 1960s and emphasized situational and cognitive influences on coping while downplaying the role of individual differences; and (c) the most recent, "third generation," whose work is represented in this special issue and focuses on the role of personality in coping while maintaining strong operational distinctions among coping, personality, appraisal, and adaptational outcomes. This introduction concludes with a discussion of unresolved conceptual and methodological issues and a brief orientation to the third-generation articles that follow in this special issue. 相似文献

ABSTRACT In this special issue, a third generation of research is represented which recognizes and demonstrates that individual differences in personality play an important role in the coping process. Although progress is apparent, there are several unresolved issues, including the best way to measure coping and whether "type of coping" matters in naturalistic settings. Three potentially important parameters of coping—range, patterning, and competence—are described, but only the first has received systematic empirical attention. The study of coping might also be advanced by researchers giving more attention to the differences between problem situations in which traits are more easily expressed ("weak" situations) versus those where normative criteria and constraints are explicit ("strong" situations). 相似文献

The Revised Conners' Parent Rating Scale (CPRS-R): Factor Structure, Reliability, and Criterion Validity 总被引:20,自引:0,他引:20

The Conners' Parent Rating Scale (CPRS) is a popular research and clinical tool for obtaining parental reports of childhood behavior problems. The present study introduces a revised CPRS (CPRS-R) which has norms derived from a large, representative sample of North American children, uses confirmatory factor analysis to develop a definitive factor structure, and has an updated item content to reflect recent knowledge and developments concerning childhood behavior problems. Exploratory and confirmatory factor-analytic results revealed a seven-factor model including the following factors: Cognitive Problems, Oppositional, Hyperactivity-Impulsivity, Anxious-Shy, Perfectionism, Social Problems, and Psychosomatic. The psychometric properties of the revised scale appear adequate as demonstrated by good internal reliability coefficients, high test-retest reliability, and effective discriminatory power. Advantages of the CPRS-R include a corresponding factor structure with the Conners' Teacher Rating Scale—Revised and comprehensive symptom coverage for attention deficit hyperactivity disorder (ADHD) and related disorders. Factor congruence with the original CPRS as well as similarities with other parent rating scales are discussed. 相似文献

This is the second in a three-part study exploring the hypothesis that near-death experiences (NDErs) assign the meaning of the NDE by using causal (effect) and semantic (affect) attributions. To test this hypothesis, 32 spontaneous verbal accounts of NDEs were analyzed. Each statement comprising the account was coded and classified according to the six attributional types in the Norton-Sahlman matrices of attributional classification. On the bases of these findings, we conclude that NDErs abstract the most significant aspects of meaning from their experiences by the use of attributions expressing the purposes of the experience and the intentions of the participants. Second, the meaning and intensity of the experience derives from attributions of both effect (causality) and affective significance: the assignment of subjective meaning to objects and events (affect). Third, the findings demonstrate that there are significant changes in NDErs' overt and affective states, reinforcing our argument that meaning and intensity of the NDE is a function of how the experiencer assigns causation, in addition to the affective significance that the experiencer places on the events constituting the NDE. 相似文献
