In a study of individual differences in long-term memory access, university undergraduates verified (1) whether an item was a member of a category, (2) whether two items belonged to the same category, and (3) whether two words had the same name. Reaction times from these tasks were correlated with verbal ability, as measured by performance on a standardized test of vocabulary and reading comprehension. A relationship was found between verbal ability and reaction time in the verification tasks. These results are contrasted with those of Hogaboam and Pellegrino (1978), who failed to find such a relationship. The results indicated that the various reaction time measures form a single factor that bears a moderate relationship to reading and vocabulary measures. 相似文献

The DIAGNOSER is a HyperCard tutorial construction system based on a framework of naive physics conceptions and developed for high school classroom use. It assesses students’ conceptions in a domain, and prescribes a course of action on the basis of that assessment. In addition, it collects data for instructional enhancement and theoretical investigations. It is sufficiently general to allow tutorials to be developed in other knowledge domains, such as probability, economics, and psychology. An advanced version exploring naive conceptions of circuit electricity is also discussed. 相似文献

A community-reinforcement approach to alcoholism 总被引:5,自引:0,他引:5
Several theoretical approaches to alcoholism exist. An opérant reinforcement approach was used in the present study to develop a new procedure that rearranged community reinforcers such as the job, family and social relations of the alcoholic such that drinking produced a time-out from a high density of reinforcement. The results showed that the alcoholics who received this Community-Reinforcement counseling drank less, worked more, spent more time with their families and out of institutions than did a matched control group of alcoholics who did not receive these procedures. This new approach appears to be an effective method of reducing alcoholism. An analysis in reinforcement terms is presented of the etiology, epidemiology, and treatment of alcoholism. 相似文献

Amplitude changes in the auditory event related response reflect differences in linguistic content and the level of processing of spoken sentences. Thus, the neurophysiology of the cognitive processes underlying speech perception can be evaluated by noninvasive techniques. Semantically correct, semantically incorrect, and grammatically incorrect sentences were processed either semantically or syntactically by 25 subjects while their EEGs were recorded. The amplitude of the P250 component to each word varied with processing level. A slow positive wave appeared after semantically correct sentences regardless of the linguistic processing level. N480 and P780 components were observed following words which made the sentences incorrect. 相似文献

The shared variance between two variables can be expressed graphically by overlapping circles. A procedure is presented for locating the circles so that the graphical and statistical relations correspond exactly. The procedure does not generalize to the representation of multiple, part, and partial correlations between three or more variables. The reasons for the nonextension are explained, and some alternative graphical representations are suggested. 相似文献

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using illustrative data from the Clark and Chase (1972) sentence-picture verification task, four loci of conflict between these two disciplines are identified. These areas of conflict center around issues of (1) theory versus measurement, (2) meaningfulness versus reliability, (3) linearity of relationships, and (4) discontinuities in performance. We conclude on the basis of observed incompatibilities that a simple derivation of differential psychology from cognitive psychology is not likely, but separate development of complementary theories may be possible. 相似文献

New Caledonian crows Corvus moneduloides (NC crows) display sophisticated tool manufacture in the wild, but the cognitive strategy underlying these skills is poorly understood. Here, we investigate what strategy two free-living NC crows used in response to a tool-length task. The crows manufactured tools to extract food from vertical holes of different depths. The first tools they made in visits were of a similar length regardless of the hole depth. The typical length was usually too short to extract food from the deep holes, which ruled out a strategy of immediate causal inference on the first attempt in a trial. When the first tool failed, the crows made second tools significantly longer than the unsuccessful first tools. There was no evidence that the crows made the lengths of first tools to directly match hole depth. We argue that NC crows may generally use a two-stage heuristic strategy to solve tool problems and that performance on the first attempt in a trial is not necessarily the ‘gold standard’ for assessing folk physics.This contribution is part of the special issue ‘Animal Logics’ (Watanabe and Huber 2006). 相似文献

To investigate whether people can resist imagination inflation--the imagination-induced increased confidence that fictitious childhood events really happened--we gave them different types of cues. In a three-stage procedure, participants: (1) rated their confidence that a list of childhood events had happened to them, (2) imagined some of these events, and (3) made confidence ratings a second time. Subjects received either no cues about the source of the imagined event, an additional source cue (perspective), an additional familiarity cue (a plausibility questionnaire), or both cues. Only subjects who had both types of cues resisted imagination inflation. These results suggest that additional cues can sometimes safeguard people from becoming more confident that fictitious events were genuine experiences. 相似文献
