HyperCard was used to develop a simplified tutoring system whose principles were based on a learning theory, and a genetics tutoring system was evaluated experimentally. Learning was studied by examining immediate versus delayed feedback after an error was made. Such tutoring systems aid in psychological studies of learning, because experimental variables can be easily manipulated. HyperCard provides a good vehicle for tutoring system development, since it requires no extensive programming skills. 相似文献

A rapid serial visual presentation (RSVP) paradigm using both one and two response dimensions was used to test parallel processing models of stimulus dimensions. Fifty subjects were asked to report the identity and/or color of a target uppercase word inserted in a series of lowercase words. The results produced a predominance of posttarget intrusions for color responses and a predominance of pretarget intrusions for identity responses. The requirement of a response to a second dimension impaired hit rates but did not change the pattern of intrusions. An examination of the distributions of intrusions in each response dimension as a function of the response given to the other dimension showed an unexpectedly high percentage of simultaneous hits, a moderate covariation between both responses, and the same patterns of intrusions when compared with the general distributions. While these results seem to be compatible with parallel models of processing for stimulus dimensions, two modifications to this model are suggested. First, the processing of response dimension(s) needs some attentional resources. Second, provision for a mixed model is indicated, which would include trials where no illusory conjunctions are formed. 相似文献

Despite importance for theories of perception, controversy exists as to whether information is available to the perceptual system about involuntary as well as voluntary eye movements. We measured the perceived direction of targets flashed briefly in an otherwise dark field during the primary phase of optokinetic afternystagmus (OKAN), an involuntary eye movement that persists in darkness following optokinetic stimulation. Perceived direction was measured by unseen pointing in one experiment and by pointing made under visual control in a second experiment. Pointing was essentially veridical in both experiments, indicating that accurate extra-retinal information about eye position (presumably, as efference copy) exists for OKAN. Illusory motion of visual targets, which can occur during involuntary oculomotor responses, therefore cannot be attributed to a lack of efference-copy signals for such eye movements. 相似文献

The developmental change in subjective probability during adolescence, an important period for establishing the probability concept, was investigated. 75 Japanese adolescents, from 12 to 23 yr. of age, were asked to make probability judgments for a lottery under 15 conditions. Analysis showed that with increase in age their subjective probability came closer to the objective probability. Discussion of these results took into consideration recent studies on the development of the concept of probability. 相似文献

The expansion of mental health services during the 1960s from a single remote mental hospital to centers and clinics in mainstream communities fostered the development of community psychology in Hong Kong. Few psychologists were initially involved in the local community mental health movement, but its momentum resulted in increasing numbers of practitioner psychologists working in community-based service settings. Community psychology in Hong Kong today consists primarily of service delivery, but also includes applied research, community organization/consultation, and community education. Despite having many parallels with the American situation, key concepts underpinning the practice of community psychology in the Territory possess their own character as a reflection of nuances in the local scene. Prospects for the continued development of community psychology in Hong Kong appear favorable. Of special relevance is the field's potential contribution to a better understanding of the psychological phenomena associated with the Territory's sociopolitical transformation in 1997. 相似文献

Bloom (1981) tested a weak version of the linguistic relativity hypothesis (i.e., "Language affects thinking though it does not determine thinking") in a series of cross-cultural experiments. According to Bloom, Chinese lacks two linguistic devices that are present in English and supposed to be critical in performing theoretical thinking. It was found that the Chinese subjects were outperformed by American counterparts in all the tests designed to assess the ability of theoretical thinking. The results were taken as evidence for the weak version of the linguistic relativity hypothesis. A methodological consideration has revealed, however, that all of his experiments except one are uninterpretable because of the lack of necessary control conditions. In addition, three experiments in the present study have demonstrated that the findings in Bloom's sole interpretable experiment were artifacts due to a methodological flaw. Further theoretical considerations reveal the inadequacy of Bloom's basic methodology and the limitation in the effects of linguistic relativity that may be possible at least theoretically. 相似文献

Prior discussion of hypothesizing as a session "guideline" has not fully clarified the derivation of hypotheses. Reviewing relevant philosophy of science literature, the authors develop the notions of evidence and evidence-gathering in systemic family therapy. The authors claim evidence-gathering and hypothesizing are interdependent, reciprocal elements of scientific understanding. The structure of evidence is described along with practical and qualitative rules for collecting and using evidence. This model is applied to a case example illustrating the logic of clinical process. Implications are discussed for family therapy training and supervision. 相似文献

Shavelson's hierarchical, multifaceted self-concept model (HMFM) has proven useful to educational and psychological researchers. The reliability and factorial validity of a well-known HMFM instrument - the Fleming-Courtney Self-Rating Scales (SRS) - were examined for a sample of 198 Filipino college students. Confirmatory factor analysis compared six structural models. A six-factor, oblique model that included two social factors (Social Acceptance and Social Anxiety) fit the data best, and a second-order factor analysis supported the hierarchical structure of the SRS. The men were significantly higher than the women on three self-concept scales, but the only large effect was for Physical Abilities, consistent with findings in a U.S. college sample. Results provided some support for the utility of both the SRS and HMFM for Filipinos. 相似文献

Studies with clinical populations have shown a high level of neuroticism amongst those with an eating disorder. It is unclear however whether the elevated neuroticism is a function of the disorder, or if it is an aetiological factor in the disorder's development. The present survey of a non-clinical female population revealed that those high in neuroticism gave higher—but not abnormally high—scores on a measure of concern about eating. The high-N group also reported a significantly greater number of undesirable life events; a greater familiarity with ‘diet literature’; increased dieting; but no difference in body weight from those in the middle and lower ranges on the N scale. On the basis of these findings it is suggested that neuroticism is an aetiological factor in disordered eating, at least with secondary if not primary disorders. It is propesed that neuroticism is one mediating psychological factor in a triadic relationship between personal environment contingencies, socio-cultural pressures for thinness and psychological variables. Suggestions are made for future investigation of the role of neuroticism in eating disturbance, with note of potential therapeutic application of such knowledge. 相似文献
