Measures of telic dominance and metamotivational state were obtained from 40 volunteer males grouped on the basis of their playing ability, before and after the performance of squash tasks. Utilising a mixed-blocks design, which controlled for order of task, subjects were required to perform two squash tasks of differing difficulty. Significant differences between groups on performance were obtained, confirming the ability classification, but no significant differences in telic dominance were found. Significant increases in mood response in the telic direction were found on pre- and posttask scores. A significant decrease in discrepancy scores (preferred arousal minus felt arousal) obtained pre- and posttask was noted, together with a significant interaction between skill level and in arousal discrepancy pre- and posttask. In all cases trends were least for the most skilled group. 相似文献

In the introductory psychology laboratory at Drexel University, we employ courseware modules that transform the computer into various pieces of psychological research equipment. Students enrolled in this course use the courseware modules in a series of experiments that investigate motor learning, perception, memory, and other psychological phenomena. In choosing this form of computerization, we have encountered challenges to our methods of instruction, both in the laboratory and in the lecture hall. Opportunities, in the form of financial and programming assistance, have also resulted from our computerization efforts. 相似文献

First-grade children and adults performed a two-choice initiation-time/ movement-time task in which signals were (a) more likely to repeat than alternate, (b) more likely to alternate than repeat or (c) equally likely to alternate or repeat. Sequential predictability influenced initiation time but not movement time for adults and for children. These results do not support the suggestion (Wickens, 1974) that sequential predictability affects initiation time and movement time for children but only initiation time for adults. Adults and first graders did differ in their response to repeated events. Adults averaged faster initiation time for alternated than repeated responses and children averaged faster initiation time for repeated than alternated responses. 相似文献

The effects of two situational (tormentor legitimacy and tormentor justification) and two personality (victim's belief in the just world and victim's Machiavellianism) factors on several reactions of a victim to his tormentor were explored. Greater conformity by victims to their tormentor's opinions occurred when the victims believed strongly in the just world and when the tormentor was well justified for his behavior; there was a greater conformity towards the tormentor in these conditions than towards a neutral nontormentor. The tormentor received less positive evaluations from the victim when he acquired his role illegitimately or when the victim was Machiavellian; when the tormentor acquired the role legitimately, he was liked no less than the nontormentor. The experimental variables did not affect behavioral imitation of the tormentor or the interpersonal distance maintained by the victim. The results failed to conform to any simple identification process. Several explanations for these results are explored and directions for additional research are discussed. 相似文献

Second-, fourth-, and sixth-grade children and adults performed a four-choice reaction time task with partially predictable sequences and 250-, 500-, and 750-msec response-to-stimulus intervals. The relative advantage for in-sequence as opposed to out-of-sequence events was independent of the response-to-stimulus interval for all ages. Children, but not adults, were slower for nonrepeated than repeated out-of sequence events and this advantage for repeated signals decreased as age increased. A second experiment extended the range of intervals tested to zero. Second graders and adults responded to four-choice partially predictable sequences with 0-, 250-, and 500-msec response-to-stimulus intervals. As in the first experiment, the difference between in-sequence and out-of-sequence events did not vary with the response-to-stimulus interval. The results suggest that both children and adults are able to process advance sequence probability information about a subsequent event in parallel with an ongoing response. 相似文献

Two experiments were performed to test a psychophysical account of parallels between biases in risky choice and intertemporal choice. Experiment 1 demonstrated the common difference effect in intertemporal choice and the common ratio effect in risky choice. As was predicted, these two biases were uncorrelated with each other, although each was correlated across monetary/health domains. This result is consistent with the supposition that these two biases result from psychophysical properties of two different dimensions (time and probability, respectively). Experiment 2 examined the magnitude effect in intertemporal choice and the peanuts effect in risky choice. These two biases were correlated with each other but were uncorrelated across monetary/health domains. This result is consistent with the supposition that these two biases result from psychophysical properties of the same dimension (utility of money or health). 相似文献

The Somatomorphic Matrix (SM) is a computer-based body image assessment program that allows assessment of the individual's body image in relation to known body composition values. To date, no study has compared the SM results to the measured body composition and assessed the usefulness in multi-ethnic samples. Japanese and Australian Caucasian males underwent testing to examine the SM body image results to their measured body composition. Japanese males showed significant (p < 0.01) discrepancy in their measured and the perceived ‘current’ muscularity compared with Australians. Both groups showed wide variability in the perception of their ‘current’ body composition in relation to the measured values, indicating an incomparability of the SM results to the measured results. The study also showed Japanese males to have lower consistency in the SM results than Australian males after a 12-month interval. In order to use the program in multi-ethnic populations further development of the program is recommended. 相似文献

This study examines the long-term efficacy of cognitive-behavioral therapy (CBT) for fear of flying (FOF) after a catastrophic fear-relevant event, the September 11, 2001, terrorist attacks. Participants (N = 115) were randomly assigned to and completed treatment for FOF using 8 sessions of either virtual reality exposure therapy (VRE) or standard exposure therapy (SE) prior to September 11, 2001. Individuals were reassessed in June, 2002, an average of 2.3 years after treatment, with a response rate of 48% (n = 55). Analyses were run on the original data and, using multiple imputation procedures, on imputed data for the full sample. Individuals maintained or improved upon gains made in treatment as measured by standardized FOF questionnaires and by number of flights taken. There were no differences between VRE and SE. Thus, results suggest that individuals previously treated for FOF with cognitive-behavioral therapy can maintain treatment gains in the face of a catastrophic fear-relevant event, even years after treatment is completed. 相似文献

Advocates of the "continuity hypothesis" have argued that innate non-verbal counting principles guide the acquisition of the verbal count list (Gelman & Galistel, 1978). Some studies have supported this hypothesis, but others have suggested that the counting principles must be constructed anew by each child. Defenders of the continuity hypothesis have argued that the studies that failed to support it obscured children's understanding of counting by making excessive demands on their fragile counting skills. We evaluated this claim by testing two-, three-, and four-year-olds both on "easy" tasks that have supported continuity and "hard" tasks that have argued against it. A few noteworthy exceptions notwithstanding, children who failed to show that they understood counting on the hard tasks also failed on the easy tasks. Therefore, our results are consistent with a growing body of evidence that shows that the count list as a representation of the positive integers transcends pre-verbal representations of number. 相似文献

To examine the association between physical dating violence victimization and risk and protective factors, an anonymous, cross-sectional, self-reported survey was administered to Latino youth (n=446) residing in suburban Washington, DC. Multivariate logistic regression models were constructed, and adjusted OR and 95% CI were examined. Approximately 9% of Latino adolescents reported physical dating violence victimization. Overall, youth who reported carrying a gun, involvement in physical fights and suicidal thoughts were at greater odds of reporting dating violence. Among females, fighting was the sole risk behavior associated with dating violence. Girls who reported a stronger sense of self were less likely to report dating violence. Among males, gun carrying, but not physical fighting, and having considered suicide were associated with dating violence. Spending time each week with a mentor was also positively associated with male dating violence victimization. Dating violence appeared to cluster with other risk behavior engagement. Important gender differences in associated risk and protective behaviors were identified and should be incorporated into primary and secondary prevention activities. 相似文献
