Two experiments investigated the effects of different types of movement responses on coincidence timing skill. The view was taken that the sensory-motor integration of the movement responses would be reflected in the accuracy and consistency of anticipation timing. A Bassin anticipation timer provided a light stimulus velocity of 3 mph for both experiments and the movements studied included a simple key press using a finger, an arm movement to a key press, and whole body movements culminating with a kick or step to a target. The experiments were modelled closely on the seminal study by Grose (1967). The results of Exp. 1 supported our prediction by demonstrating superiority of the finger task over the two larger movements for all measures of coincidence timing ability. The purpose of Exp. 2 was to compare the slightly different versions of the whole body task-that used in the first experiment and that used by Grose (1967). The results confirmed the close similarity of the two movement tasks and re-affirmed the results of Exp. 1. Exp. 2 also investigated sex effects on coincidence timing ability and, in contrast to previous evidence indicating that females perform with less accuracy and consistency than do males, no significant differences were found. Analysis of practice effects showed that, although there were no significant improvements over trial blocks in Exp. 1, there were significant improvements in Exp. 2. Comparisons with other research suggests that repeated practice in solving a coincident timing problem using whole body movements can lead to improved performance. In general, the findings are consistent with the constructs of action theory and emphasize the roles perceptual and movement variables have in defining situational constraints. Also, findings indicate that proficiency in coincidence anticipation appears to be influenced by the planning and organisation required for movement execution. 相似文献

Three experiments investigated memory performance in the retrieval practice paradigm (Anderson, Bjork, & Bjork, 1994; Anderson & Spellman, 1995). This paradigm produces a retrieval-induced forgetting effect, wherein practicing some members of a studied category decreases the recall of other members of that category relative to a baseline. Our findings indicate that the retrieval-induced forgetting effect is replicable but that previous findings supporting an inhibitory account of this phenomenon may not be. 相似文献

Previous studies have implicated depression, self-defeating behaviors, and self-destructive behaviors in suicide ideation. The present research directly compared these three concepts as predictors of both males' (n = 51) and females' (n = 78) suicide ideation. Analysis confirmed sex differences, with depression and self-defeating behaviors predicting females' suicide ideation, and self-destructive behaviors predicting males' suicide ideation. These results suggest that suicide may be related to these subtle yet relevant factors which may not be easily detected by mental health workers. 相似文献

Children's artistic responses to musical intervals 总被引:4,自引:0,他引:4
In one experiment, White South African boys drew pictures in response to four musical intervals. In the second, the subjects were of both sexes and drawn from White, urban Black, and rural Black populations. Six intervals were used. Drawing content was similar cross-culturally. Consonances were perceived as generally positive; dissonances, generally negative. There was also an activity dimension. Children in a lower grade drew more concrete pictures than did those in a higher grade, regardless of age. Even young listeners were fairly consistent in their responses. This suggests that perception of musical meaning is a universal rather than culturally based phenomenon. 相似文献

Racism as a stressor for African Americans. A biopsychosocial model. 总被引:30,自引:0,他引:30
Various authors have noted that interethnic group and intraethnic group racism are significant stressors for many African Americans. As such, intergroup and intragroup racism may play a role in the high rates of morbidity and mortality in this population. Yet, although scientific examinations of the effects of stress have proliferated, few researchers have explored the psychological, social, and physiological effects of perceived racism among African Americans. The purpose of this article was to outline a biopsychosocial model for perceived racism as a guide for future research. The first section of this article provides a brief overview of how racism has been conceptualized in the scientific literature. The second section reviews research exploring the existence of intergroup and intragroup racism. A contextual model for systematic studies of the biopsychosocial effects of perceived racism is then presented, along with recommendations for future research. 相似文献

Williams and Best's (1982, 1990a) cross-culturalgender stereotype data from 25 countries, previouslyanalyzed in terms of affective meanings, ego states, andpsychological needs, were re-analyzed in terms of the Five Factor Model (FFM) of personality.In each country, participants were approximately 100university students, equally divided by gender. Withresults averaged across all countries, it was found that the pancultural male stereotype was higherthan the pancultural female stereotype on Extraversion,Conscientiousness, Emotional Stability, and Openness toExperience while the pancultural female stereotype was higher on Agreeableness. Re-analysis of thestereotype data from Japan and Pakistan, which had beenfound relatively atypical in previous analyses, revealedFFM profiles generally similar to the pancultural profiles. The evaluative nature of each factoris discussed and related to the stereotypes associalization models. 相似文献

This article examines the personal and archetypal aspects of images from six dreams that occurred during the illness and after the death of the dreamer's sister. It connects the dream images to the unresolved issues in the relationship between siblings and to the dreamer's own reflections on typology. It also explores the larger questions concerning the psychological process of grief, the common occurrence of synchronistic events related to death and loss, and includes Jung's comments on life and death. Finally, the article suggests solutions to our very human fears of death and encourages the development of our capacity to discover a personal mythology, a working sacred story, of “the beyond” or “life” after death. 相似文献

In the popular folklore three-score-years-and-ten is treated as a fair innings for people, and thereby serves as an informal reference point for judgements about distributive justice within a community. But length of life alone is an insufficient basis for such judgements - a person's health-related quality-of-life also needs to be taken into account. If one of the objectives of public policy is to reduce inequalities in lifetime health, it will be demonstrated that this is very likely to require systematic discrimination against the older members of a community. The notion of community solidatity will also be tested, because a decision will need to be made as to whether the same fair innings applies to all members of the community, or whether some are entitled to more than others. The strength of the fair innings principle is that it brings these issues to the fore in a systematic way which should ais their resolition in a practical context. 相似文献
