The acculturation attitudes and traditionalismof Chinese university students in Toronto, Canada, wereinvestigated. Chinese men were significantly moretraditional than Chinese women in their beliefs and expectations regarding family hierarchy and thesocial roles of women and men, but they did not differin perceptions of their parents' construal of familyrelations and gender roles. Generational discrepancy between self and perceived parental values wasfound for Chinese women but not for men in the study,suggesting greater conflict with regard to traditionalgender role and cultural values for women. The acculturation attitude of separation predictedstudents' traditionalism, and marginalization predictedparents' perceived traditionalism. Gender differencesand the relevance of different modes of acculturation with regard to traditionalism are discussed inthis article.  相似文献

From 1978 through 1995, a sex ratio of 6.6:1 of boys to girls (N = 275) was observed for children referred to a specialty clinic for gender identity disorder. This article attempts to evaluate several hypotheses regarding the marked sex disparity in referral rates. The sexes did not differ on four demographic variables (age at referral, IQ, and parent's social class and marital status) and on five indices of general behavior problems on the Child Behavior Checklist; in addition, there was only equivocal evidence that boys with gender identity disorder had significantly poorer peer relations than girls with gender identity disorder. Although the percentage of boys and girls who met the complete DSM-III-R criteria for gender identity disorder was comparable, other measures of sex-typed behavior showed that the girls had more extreme cross-gender behavior than the boys. Coupled with external evidence that cross-gender behavior is less tolerated in boys than in girls by both peers and adults, it is concluded that social factors partly account for the sex difference in referral rates. Girls appear to require a higher threshold than boys for cross-gender behavior before they are referred for clinical assessment.  相似文献

This research combined experimental and correlational methods to investigate the effects of social support on social problem-solving effectiveness and perceived stress. During a wait period, college students were given the opportunity to work on practice items from a mildly stressful social problem-solving task, either alone or in the company of a close friend. Participants and friends were allowed to talk about the practice items but were not required to do so, and supportive transactions were tape recorded and content analyzed. All students then completed social problem-solving and perceived stress items alone. Participants who waited with friends did not show superior problem-solving effectiveness unless companions provided particular supportive behaviors. Participants with high perceived support scores rated the experiment as less stressful than those with low scores, but perceived support was not related to companions' actual supportive behaviors. The results were discussed in terms of implications for understanding the mechanisms of social support.  相似文献

This study examined whether the sexual behavior of adult male mice is influenced by exposure in early postnatal life to brief episodes of mating. Another focus of interest was the interplay between a genetic disposition for aggressive behavior and the early exposure experiences. The subjects used in the study were male mice of the fiftysixth generation of selection for high (Turku aggressive, TA) and low (Turku non-aggressive, TNA) levels of aggressiveness. Moderately aggressive males of the parental strain (normal, N) were also used. Subjects of each strain were exposed from 21 to 32 days of age to mating mice behind a wire mesh screen. Control subjects were placed in a comparable enclosure, but were exposed to nothing. The results showed that male mice exposed to mating early in life showed a higher rate of activities in the sexuality tests, including aggressive responses. A genetic potential for aggressive behavior was related to a higher degree of sexual activity, and the early exposures optimized the hereditary attributes. The relation between sexual and aggressive behavior is discussed. © 1994 Wiley-Liss, Inc.  相似文献

Millers Living Systems Theory (LST) is known to be very comprehensive. It comprises eight nested hierarchical levels. It also includes twenty critical subsystems. While Millers approach has been analyzed and applied in great detail, some problematic features remain, requiring further explication. One of these is the relationship between reduction and emergence in LST. There are at least four relevant possibilities. One is that LST exhibits neither clear reductionism nor emergence, but is essentially neutral in this regard. Another is that the apparent comprehensiveness of LST is illusory, as the approach remains vulnerable to reduction that could ultimately reduce it to a shadow of its present self. The charge of reductionism has been made by critics leading Miller to defend this theory vehemently as nonreductionist in nature. A third possibility is that LST is not reductionist, but is in fact an emergent theory. Miller makes this claim quite strongly. A fourth possibility, and in some ways the most analytically problematic, is that LST exhibits evidence of both reductionism and emergence simultaneously. Some critics might see this fourth situation as evidence of a troubling paradox or anomaly that must be resolved before further progress can be made in the explication and application of LST. The purpose of the paper is to remove this apparent anomaly. The paper removes this anomaly by differentiating between new-variable emergence and transformational emergence. No concrete evidence is found to contradict Milers claim of emergence in LST, and thus no true anomaly exists.  相似文献

This research examined the effects of mastery vs. performance training goals and learning and performance goal orientation traits on multidimensional outcomes of training. Training outcomes included declarative knowledge, knowledge structure coherence, training performance, and self-efficacy. We also examined the unique impact of the training outcomes on performance adaptability by predicting generalization to a more difficult and complex version of the task. The experiment involved 60 trainees learning a complex computer simulation over 2 days. The research model posited independent effects for training goals relative to goal orientation traits and independent contributions of training outcomes to the performance adaptability of trainees. The findings were consistent with the proposed model. In particular, self-efficacy and knowledge structure coherence made unique contributions to the prediction of performance adaptability after controlling for prior training performance and declarative knowledge. Implications and extensions are discussed. Copyright 2001 Academic Press.  相似文献
