124 junior high school students (Grades 5 to 8) from a small school district in north central Kansas completed the Beck Depression Scale, the Maze test, and the Which-to-Discuss test. Background information, such as age, sex, grade, and marital status of parents, were also collected. There were no significant differences between boys and girls of divorced and nondivorced parents or across grades for scores on the Which-to-Discuss (specific curiosity) and depression, but boys scored significantly higher on the Maze test (diversive curiosity). No differences were noted between the students of divorced and nondivorced parents or across grades. Scores on Which-to-Discuss test and Maze test were not significantly correlated, but scores on one Maze test and depression correlated positively and significantly. When these students scored as more depressed, although in the normal range, they tended to score higher on diversive curiosity. 相似文献

Preferential looking experiments investigated 5- and 8-month-old infants' perception and understanding of the motions of a shadow that appeared to be cast by a ball upon a box. When all the surfaces within the display were stationary, infants looked reliably longer when the shadow moved than when the shadow was stationary, indicating that they detected the shadow and its motion. In further experiments, however, infants' looking was not consistent with a sensitivity to the shadow's natural motion: They looked longer at natural events in which the shadow moved with the ball or remained at rest under the moving box than at unnatural events in which the shadow moved with the box or remained at rest under the moving ball. These findings suggest that infants overextend to shadows a principle that applies to material objects: Objects move together if and only if they are in contact. In a final experiment, infants were habituated to a moving shadow that repeatedly violated one aspect of the contact principle. In a subsequent test they failed to infer that the shadow would violate another aspect of the contact principle. Instead, they appeared to suspend all predictions concerning the behavior of the shadow. 相似文献

Group inequalities in the United States are most often attributed to the characteristics of the individuals who belong to these groups; thinking about structural causes of group inequalities is rare. This paper reviews cognitive, cultural, and systemic reasons for this bias. The efficacy of education as a way to increase structural thinking was investigated in two studies of college students' causal thinking about group inequalities. Both studies involved a course on intergroup relations that covered structural sources of racial or ethnic inequalities. Results supported hypotheses that the course would increase structural thinking about racial or ethnic inequality, and that structural thinking would generalize to inequalities not explicitly covered in the course. Both course content and active learning pedagogy were related to structural thinking about inequalities. Active learning was also related to applying structural thinking to targets of change. 相似文献

This article surveys the extant literature on mental imagery as used in athletics for performance enhancement, arousal regulation, affective and cognitive modification, and rehabilitation. For each category of use, applications are discussed, an overview of the empirical and case-study research findings is presented, and the research is critiqued. A concluding section recommends directions for future research on uses of mental imagery in athletics. 相似文献

An assumption underlying the common practice of permitting a juror to serve on more than one jury is that jurors can and will reach multiple verdicts independently. Two studies were carried out to examine this assumption. The first experiment had mock jurors consider several cases in succession. Subjects exhibited a clear contrast effect on the strength of evidence; those subjects who initially saw strong prosecution cases were less likely to convict in a moderate test case than those who had initially seen wcak prosecution cases. In the second study, the contrast hypothesis was tested for actual juries' verdicts through archival analyses. The results of this field study paralleled those obtained in the experimental study. The discussion focused upon alternative theoretical explanations for these results, implications for trial practice, and the strengths and weak-nesses of the methodologies applied in these studies. 相似文献

A sentence in discourse may appear in the passive voice to emphasize the logical object rather than the logical subject when it is thematically more important. Two experiments are reported that explore the impact of this textual function of voice on sentence memory. The first experiment required subjects to listen to prose passages and then recall them. Sentences were recalled predominantly in the active voice regardless of voice or thematic focus in the prose passage, showing that the English-language bias for the active voice was a more important determinant of sentence reconstruction than was the experimental manipulation of thematic context. The second experiment required subjects to listen to or read either prose passages or lists of unrelated sentences and then to try to recognize key sentences that were either unchanged or changed lexically, semantically, or in voice. Recognition, both overall and specifically for voice, was better for sentences that were read than for those that were heard, and recognition for semantic change was consistently higher than for any other. Only when passages were read was there evidence in support of a thematic textual influence on memory for sentence voice.This research was supported in part by NIMH Grant 32063. 相似文献

To assess Welford's dual controlling factor interpretation of Fitts' law, 20 scuba divers performed a reciprocal tapping task. In an attempt to separate the two factors, the subjects were tested on land and underwater. This does not change the basic parameters of the task but does put the subjects under informational stress, in that underwater the movement is less ballistic in nature and should require the processing of more information (feedback) in each tap. On land, the contributions of movement amplitude and precision were approximately equal. However, the relative changes in contribution of these factors to movement time underwater suggests that these parameters do in fact represent separate controlling factors. 相似文献
