In 3 experiments, participants, on signal, moved a cursor from a central position to 1 of 8 numerically labeled locations on the circumference of a clock face. Movements were controlled by a mouse in 1 of 4 conditions: vertical reversal, horizontal reversal, combined reversals, or normal (i.e., no reversals). Participants were trained in 1, 2, or 3 of these conditions and were tested 1 week later with either the same or a different condition. There were improvements across training and perfect retention across the delay. There was little or no transfer, however, even when training involved combined reversals or multiple conditions. These results illustrate severe specificity of training and are interpreted in terms of acquired inhibition of normal responses. 相似文献

In this study, we investigated the psychometric properties of the Sensation Seeking Scale-V (SSS-V; Zuckerman, Eysenck, & Eysenck, 1978). Participants were 498 undergraduate students at a public university. A confirmatory factor analysis supported the SSS-V four-factor structure. In addition, the internal consistency was high and the convergent validity of the SSS-V was supported. These findings replicate research supporting the construct validity and reliability of the SSS-V in a nonclinical college sample. 相似文献

According to common judicial standard, judgment in favor ofplaintiff should be made if and only if it is more probable than not thatthe defendant's action was the cause for the plaintiff's damage (or death). This paper provides formal semantics, based on structural models ofcounterfactuals, for the probability that event x was a necessary orsufficient cause (or both) of another event y. The paper then explicates conditions under which the probability of necessary (or sufficient)causation can be learned from statistical data, and shows how data fromboth experimental and nonexperimental studies can be combined to yieldinformation that neither study alone can provide. Finally, we show thatnecessity and sufficiency are two independent aspects of causation, andthat both should be invoked in the construction of causal explanations for specific scenarios. 相似文献

《Journal of Fluency Disorders》1989,14(6):429-445The differences in the number of disfluencies of 3-, 5-, and 7-year-old nonstuttering children were investigated as syntactic complexity was varied in three different syntactic constructions: 1) simple affirmative declarative with copula + ing (SAAD), 2) future (FUT), and 3) passive (PAS) within a sentence imitation and a sentence-modeling task. The subjects repeated 30 sentences from the imitation task stimuli and produced response constructions from 30 pictures from the modeling task stimuli. The 3-year-olds exhibited significantly more disfluencies than the 5-year-olds, and the 5-year-olds produced significantly more disfluencies than the 7-year-olds. All three age groups produced significantly more disfluencies on the modeling task than on the imitation task. A significant complexity effect was demonstrated for the PAS construction. Results are compared to previous research findings and discussed with reference to hypothesized linguistic complexity and task difficulty. 相似文献

The context in which a word occurs could influence either the actual decoding of the word or a postrecognition judgment of the relatedness of word and context. In this research, we investigated the loci of contextual effects that occur in lexical priming, when prime and target words are related along different dimensions. Both lexical decision and naming tasks were used because previous research had suggested that they are differentially sensitive to postlexical processing. Semantic and associative priming occurred with both tasks. Other facilitative contextual effects, due to syntactic relations between words, backward associations, or changes in the proportion of related items, occurred only with the lexical decision task. The results indicate that only associative and semantic priming facilitate the decoding of a target; the other effects are postlexical. The results are related to the different demands of the naming and lexical decision tasks, and to current models of word recognition. 相似文献

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. On a measure of children's shape identification (n = 93), there was no difference in performance between objects and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. These results suggest flexibility in the materials that can be used during assessment. Pictures, or 2D renderings of 3D objects, which can be easily printed and reproduced, may be sufficient for assessing counting and shape knowledge without the need for more cumbersome concrete manipulatives. 相似文献

The message that women should be thin comes from many sources; some of which may be using the terminology loosely. To test this, the Figure Rating Scale was mailed to 547 personal ad writers to examine the actual preferences of those seeking a thin partner, those seeking a physically fit partner, and those giving no weight preference. Respondents indicated ideal and acceptable body sizes for partners. The ethnicity of respondents was 85.1% White, 7.5% Hispanic, 1.4% African American, 0.7% American Indian, and 4.1% other. The mean education level was 16.6 years and the average annual income was about $40,000. Although males in the three ad categories had statistically significant differences in their choice of an ideal figure, the actual figure size differences appeared negligible, and men did not differ in the number of figures they found acceptable. Females chose the same figure as ideal despite different weight requests. The implications of males accepting a wide range of body sizes for a partner despite specifically requesting a thin one are discussed. 相似文献

The Effects of Tai Chi Chuan Relaxation and Exercise on Stress Responses and Well-Being: An Overview of Research 总被引:3,自引:0,他引:3
The rationale of this article is to review, analyze, and discuss studies concerning the role of Tai Chi in stress management and well-being, linking those studies to research on exercise, yoga, and relaxation with regard to physiological and psychological wellness. All studies reported in PsychLit and Medline between 1996 and 1999 directly related to the subject, plus other studies relevant for the analysis, are addressed in this review. Studies reviewed in this article characterize Tai Chi as a form of moderate exercise. Although Tai Chi may not be suitable for achieving aerobic fitness, it may enhance flexibility and overall psychological well-being. Cognitively, there are indications that Tai Chi exercise may lead to improvements in mood. However, it is not clear whether the positive effects of Tai Chi are due solely to its relaxation and meditation component, or whether they are the consequence of various peripheral factors, since it is known that stress reduction often occurs when we indulge in activities we find pleasurable and satisfying. An important finding is that all studies on the benefits of Tai Chi for senior adults have revealed positive results. 相似文献
