Forty-four preschool children ranging from three to five years of age received a series of stones in which the protagonists experience happiness, sadness, or fear These protagonists were portrayed as either similar or dissimilar to the child, and the situations depicted were either familiar or unfamiliar to him/her as well The children's task was to infer the emotions experienced by the protagonists Results indicate that children were more accurate in judging the emotions of similar target persons than they were for dissimilar ones Familiarity with the situation, on the other hand, had no effect on accuracy Children were more accurate in identifying happiness and sadness than they were in judging fear, and age was positively related to judgmental accuracy for the former two but not for the latter These results help to resolve the controversy arising from earlier studies of empathy development which failed to disentangle the similarity and familiarity dimensions 相似文献

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed. 相似文献

I have taken a Kantian approach to the issue of pornography and degradation. My thesis is that by perpetuating derogatory myths about womankind, for the sake of financial gain, the pornography industry treats the class of women as a means only, and not as composed of individuals who are ends in themselves. It thus de-grades all women, as members of this class, imputing to them less than full human status. 相似文献

The experiments examined the contributions of forebrain noradrenaline and environmental enrichment to recovery of place navigation ability in rats after hemidecortication in infancy or adulthood. Noradrenaline depletion did not affect recovery from neonatal hemidecortication, although the early hemidecortications did allow sparing of function relative to adult operates. Noradrenaline depletion also failed to attenuate the positive effects of enriched housing on otherwise normal rats. Noradrenaline depletion did retard recovery of adult hemidecorticate rats housed in standard laboratory cages, but it did not retard recovery of adult hemidecorticate rats housed in enriched environments. The results suggest that noradrenaline is importantly involved in enhancing recovery from brain damage when other sources of compensation (e.g., neonatal injury, enriched environment) are absent. 相似文献

Sex differences in the effects of gonadectomy on amphetamine-induced rotational behavior in rats 总被引:2,自引:0,他引:2
The effects of gonadectomy on amphetamine-induced rotational behavior were studied in male and female rats. Different systemic doses were used to produce equivalent brain concentrations of the drug in each group, thereby controlling for sex differences in the metabolism of amphetamine. Ovariectomy of female rats significantly attenuated amphetamine-induced rotation, whereas castration of males was without effect. The results support the idea that in females, the endogenous gonadal hormones facilitate functional activity in the mesostriatal dopamine system. 相似文献

Though the term “new technology” is widely used and discussed, there has been very little systematic study of attitudes to
technology and their relation to other beliefs and group memberships. This article describes an initial investigation into
the nature of attitudes towards new technology (n=534 undergraduates) and demonstrates that, as yet, these attitudes are only weakly structured and are not fully integrated
with other social beliefs. General evaluations of the benefits of technological advance appear to be almost unrelated to beliefs
about the inevitability of these advances or the desire to acquire training to deal with them. Contrary to popular expectations,
evaluations of video games are unrelated to other beliefs about technology while other social beliefs are, as yet, only weakly
integrated with these attitudes. This study also identifies gender differences in the assessment of potential benefits and
highlights other differences attributable to academic group memberships. These finding are discussed with reference to the
literature on sex-role stereotyping and group socialization processes. 相似文献

In order to examine the possibility that the attribution of more aggression to boys may be in part a function of observer bias, 40 adults were asked in Study 1 to record the degree of aggression in a series of line drawings that showed children interacting. It was found that a significant subset of both males and females recorded more aggression for boys than for girls when they scanned scenes that showed numerous children interacting. When they rated a series of drawings of two children interacting, males rated boys as significantly more aggressive than girls. Study 2 examined 48 adults' responses under one of three instruction conditions. The findings of Study 1 were replicated. Additionally, it was found that some forms of instruction eliminate sex-typed biases while others yield significant biases among both male and female untrained observers. These results are interpreted in light of the literature on schematic processing. Implications pertaining to the socialization of aggression and to research on sex differences in aggression are discussed. 相似文献

Children of divorce represent a diverse population at risk for subsequent psychological problems, whose interests are insufficiently understood or protected by the legal system or the mental health community. Although many children weather the stress of marital breakdown without psychopathological sequelae, a significant number show lasting difficulties. Information concerning the psychological adaptation of these children has increased rapidly during the past decade, but it remains unequel to the task of guiding family policy in this arena. Current knowledge identifies child gender and developmental stage as crucial factors that interact with the chronic stresses of postdivorce family life to produce short-and long-range impediments to the maturation of these vulnerable young people. There is a critical need to facilitate understanding and cooperation between the behavioral sciences and the legal profession on behalf of children in divorced families. The major research tasks relevant to enlightened public policy lie ahead. 相似文献

Earlier work on the quality of care in settings for severely and profoundly mentally-handicapped adults raised the question whether any useful purpose is served by promoting the extensive use of simple recreational materials to occupy people. Data were collected by direct observation on the activity of 6 adults living in a staffed house organized to promote engagement in household activities. Observations were taken over 5 weekdays from 07.00 to 10.00 and 15.00 to 23.00hr. The results showed that Ss spent between 22 and 67% of available time in purposeful activity. Between 27 and 65% of purposeful activity was engagement in domestic or housework tasks. Even the most handicapped people spent more time engaged in housework than in leisure and recreational tasks. The implications of these data are commented on and measurement issues which arise in ordinary housing as opposed to institutional settings are discussed. 相似文献
