This experiment assessed the efficacy of proprioceptive and visual information for the performance of "vertical position" by synchronized swimmers. Three skill groups of 5 senior, 5 intermediate, and 5 novice synchronized swimmers performed 40 vertical positions under four conditions. The conditions were: self-initiated with and without vision, and following experimenter perturbation, with and without vision. The dependent measure was degrees of error from true vertical. Analysis indicated that either proprioception or proprioception and vision may be used in performing vertical positions. A significant main effect was found among skill groups. 相似文献

Sociobiological theory suggests that aggression coupled with altruism is highly adaptive for males in all social systems, including the family, whereas sex-role convergence theory indicates that lower levels of aggression are most adaptive for men, particularly at mid-life. The purpose of this study was to determine the role that testosterone, as a proxy for aggression, plays as an adaptive mechanism in the lives of middle-aged males. The sample used in this study consisted of 37 middle-aged (39–50 years of age) males employed in professional occupations in a midwestern metropolitan area. Testosterone levels were regressed on factors typically found to be related to male satisfaction with family life at mid-life: marital satisfaction, parent-adolescent communication, amount of emotional expressiveness, and androgynous characteristics; recent positive and negative stressors and trait anxiety were statistically controlled. Results of step-wise multiple regression analysis indicated that low levels of testosterone were significantly (R = .34, P < .01) related to enhanced marital and parental relationships and androgynous behaviors; however, emotional expressiveness was significantly related to high levels of testosterone. 相似文献

Alcohol-related expectancies have been recently proposed as potentially important determinants of drinking behavior. This study describes the development of a New Zealand measure of such beliefs, the Drinking Expectancy Questionnaire (DEQ). Items selected through interviews, literature review, and the modification of other relevant questionnaires were piloted on 333 drinkers in a community sample and 275 college students. Factor analyses of both samples revealed nine alcohol reinforcement domains relating to assertiveness, affective change, sexual enhancement, social enhancement, relaxation, cognitive impairment, dependence, carelessness, and aggression. The potential clinical and research possibilities using this revised expectancy measure are briefly discussed, along with the scale's strength and weaknesses.The financial assistance of the Alcoholic Liquor Advisory Council of New Zealand in conducting this study is gratefully acknowledged. 相似文献

Information is provided on the process of creating psychological simulations using LISP. A simulation is described, and the difference between progamming and simulation and “normal” programming is also provided, along with programming and debugging tips. 相似文献

Educably mentally retarded (EMR) students and nonhandicapped students from their mainstream classes completed semantic differential ratings of a stereotypic popular teen-ager, juvenile delinquent, and special education student. Subjects also rated their global self-concepts and situation-specific self-concepts within the mainstream and the special class settings. Ratings were done at the beginning (Time 1) and the end (Time 2) of a semester. Results showed that mainstream classes did not "de-label" EMR students. Within the mainstream class, the number of EMR students who saw themselves as similar to a special education student significantly increased over time. Moreover, at Time 2, EMR students were more likely to think of themselves as similar to a special education student in their mainstream class than in their special education class. However, EMR subjects' global self-concepts did not change. Implications for mainstreaming are discussed. 相似文献

Different methods of lexical access for words presented in the left and right visual hemifields 总被引:4,自引:3,他引:1
Right-handed adults were asked to identify by name bilaterally presented words and pronounceable nonwords. For words in the normal horizontal format, word length (number of letters) affected left visual hemifield (LVF) but not right visual hemifield (RVF) performance in Experiments 1, 2, 3, 5, and 6. This finding was made for words of high and low frequency (Experiment 6) and imageability (Experiment 5). It also held across markedly different levels of overall performance (Experiments 1 and 2), and across different relative positionings of short and long words in the LVF and RVF (Experiment 3). Experiment 4 demonstrated that the variable affecting LVF performance is the number of letters in a word, not its phonological length. For pronounceable nonwords (Experiment 7) and words in unusual formats (Experiment 8), however, length affected both LVF and RVF performance. The characteristics identified for RVF performance in these experiments also hold for the normal reading system. In this (normal) system the absence of length effects for horizontally formatted words is generally taken to reflect the processes involved in lexical access. Length effects in the normal reading system are thought to arise when lexical access for unusually formatted words and for the pronunciation of nonwords requires the short-term storage of information at a graphemic level of analysis. The characteristics of LVF performance indicate that horizontally formatted words presented to the right cerebral hemisphere can only achieve lexical access by a method that requires the short-term storage of graphemic information. This qualitative difference in methods of lexical access applies regardless of whether the right hemisphere is seen as accessing words in the left hemisphere's lexicon or words in a lexicon of its own. 相似文献

Terms of empowerment/exemplars of prevention: Toward a theory for community psychology 总被引:3,自引:0,他引:3
Julian Rappaport 《American journal of community psychology》1987,15(2):121-148
In order to develop theory any community of scientists must agree as to what constitutes its phenomena of interest. A distinction is made between phenomena of interest and exemplars. The concept "prevention" is viewed as an exemplar, whereas the concept "empowerment" is suggested as a leading candidate for the title "phenomena of interest" to Community Psychology. The ecological nature of empowerment theory is described, and some of the terms of empowerment (definitions, conditions, and periods of time) are explicated. Eleven assumptions, presuppositions, and hypotheses are offered as guidelines for theory development and empirical study. 相似文献

Previous research indicates that children from violent marriages are more likely to suffer from conduct problems and/or anxiety disorders than children from nonviolent, satisfactory marriages. However, knowledge regarding specific factors present in violent marriages relating to child problems is limited. The present study examined the relationships involving interspousal aggression, parent-child aggression, and child behavior problems in a sample of 45 children from maritally violent families. Mothers indicated how often their children witnessed interspousal aggression and were victims of parent-child aggression. Mothers also rated their children's problem behaviors while children reported on their own depressive symptoms. The witnessing of interspousal aggression was highly associated with parental aggression directed toward children. Parent-child aggression related to attention problems, anxiety-withdrawl, motor excess, and conduct problems in children. However, the witnessing of interspousal aggression was not significantly related to child behavior problems. These results are consistent with theoretical predictions linking marital problems to child behavior by virtue of their association with parenting.This research was supported in part by a Grant-in-Aid of Research awarded to the first author by Sigma Xi, the Scientific Research Society, and NIMH Grant No. MH35340 awarded to the third author.
