采用“间接学习—回忆”实验范式,考查方位记忆的生存优势及生存记忆的性别差异。在电脑屏幕上下左右4个方位随机呈现动物或食物图片,被试相对于中央点对捕获动物或采集食物的难易程度进行评价,然后进行方位回忆测验。实验1和实验2为2(情境:生存情境vs.比赛情境)×2(性别:男vs.女)的被试间设计,发现当狩猎动物或采集食物活动与生存相关时,图片方位回忆的正确率较大;实验3为2(情境:生存狩猎情境vs.生存采集情境)×2(性别:男vs.女)的混合设计,发现不同性别被试在两种生存情境中的图片回忆正确率存在差异。表明方位记忆具有生存优势,生存记忆存在性别差异。 相似文献

Children’s perceptions of the emotional reactions of same- and different-sex characters in stories containing ambiguous and
unambiguous emotional contexts were examined. According to the Parallel-Constraint-Satisfaction Theory (Kunda and Thagard.
Psychological Review, 103, 284–308, 1996), stereotypes are more likely to be utilized in ambiguous contexts, defined here as those likely to elicit
multiple emotional responses. Seventy suburban U.S. preschoolers were read vignettes describing boys or girls in ambiguous
or unambiguous emotion-inducing events and reported how the vignette characters were feeling. Results suggest that the perceptions
of participants were more likely to reflect gender–emotion stereotypes (e.g. perceiving males as angry and females as sad)
in ambiguous contexts than in unambiguous contexts. Results are discussed in terms of children’s emerging understanding of
gender–emotion stereotypes. 相似文献

Adaptive Memory: Remembering With a Stone-Age Brain 总被引:1,自引:0,他引:1

ABSTRACT— If memory evolved, sculpted by the processes of natural selection, then its operating characteristics likely bear the "footprints" of ancestral selection pressures. Psychologists rarely consider this possibility and generally ignore functional questions in their attempt to understand how human memory works. We propose that memory evolved to enhance reproductive fitness and, accordingly, its systems are tuned to retain information that is fitness-relevant. We present evidence consistent with this proposal, namely that processing information for its survival relevance leads to superior long-term retention—better, in fact, than most known memory-enhancement techniques. Even if one remains skeptical about evolutionary analyses, adopting a functional perspective can lead to the generation of new research ideas. 相似文献

Vardit Rispler-Chaim 《The Journal of religious ethics》2008,36(1):53-76
Selecting the sex of a fetus has been a desire of parents in many different cultures. Modern Muslim religious scholars have identified advantages and disadvantages of this practice, permitting it in certain cases while forbidding it in others. In general, they do not appear to desire that selection of sex become a common practice, yet they are willing to allow it for personal reasons. This case‐by‐case approach exemplifies a key aspect of Muslim ethical discourse. After an overview of justifications for fetal sex selection in different cultures, I turn to a discussion of authoritative Islamic sources. I then analyze the reasoning of several modern authorities who deal with the issue. In the absence of a clear religious text on the subject, scholars seem inclined to legitimize sex selection, and in so doing they appear strongly influenced by social attitudes. 相似文献

Differential emotions theory (DET) (The face of emotion. Appleton‐Century‐Crofts: East Norwalk, CT, 1971) posits that the smile functions in part to communicate and/or reflect social affiliation and plays an important role in children's social development. While children's positive emotion expressions have received attention from peer relations researchers in observational studies and within correlational designs, there is almost no experimental evidence for the impact of the smile. Building on existing studies, the present study examined DET predictions within an experimental design. More specifically, we examined the impact smiles have on lower‐income preschool children's nominations for preferred playmates. Both boys and girls tended to nominate unfamiliar playmates who smiled. Additionally, some evidence suggested that preference for smiling playmates seemed more critical to girls' than boys' social functioning. Unlike among boys, teachers rated girls who exhibited a greater preference for smiling playmates as higher in social competence. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Abstract: This article raises the question of how the ontological status of virtual objects bears on their intrinsic value. If virtual objects are unreal or less real than physical objects, does it mean that they will have less intrinsic value? If they have intrinsic value, what are the explanations for this value, and how do they relate to the ontological status of the virtual objects? First, the article reviews recent work concerning the ontological status of virtual reality and virtual objects. Second, it argues that in some cases the ontological status of virtual objects does undermine the value placed in them, in that the objects can fail to have the properties that ground the value attributions made to them, while in other cases their ontological status is not important. Finally, the article relates the grounding of value attributions to philosophical theories of value, in particular, perfectionism and hedonism. 相似文献

Longitudinal analysis of objectified body consciousness, body esteem, self-acceptance, and weight-related attitudes and behaviors
in young adults (115 women and 49 men), who were undergraduates in 1993, tested hypotheses developed from theory on the social
construction of gendered bodies and the developmental contexts of the post-college transition. Gender differences in body
surveillance, body shame, and body esteem and the relationships between these persisted, whereas the relationship between
body esteem and self-acceptance decreased for women and was similar to men at Wave 2. For both women and men, body surveillance
and body shame decreased and body esteem increased over time, even though BMI also increased. Men wanted to lose weight at
levels similar to women at Wave 2 and were equally likely to exercise to control weight, but they were less likely than women
to diet. These results fit both cohort and age-related changes models of body experience for women and men. 相似文献

The purpose of this study was to investigate changes in externalizing and internalizing problem behaviours in 6‐year‐olds with a focus on sex differences. Teachers rated problem behaviours at the beginning and at the end of the school year, 8 months apart, in 370 children (197 boys and 173 girls) attending 22 school preparatory classrooms. Although the majority of the children were quite stable, considerable negative and positive changes for both boys and girls in problem behaviours were found. The results showed that girls were more likely to change their externalizing behaviours in a positive direction than boys, whereas a tendency to the opposite pattern was found for internalizing behaviours. Boys were also found to be more prone to a negative change in problem behaviours of both types than girls were. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

“May I present you: my disgust!” – Declared disgust sensitivity in the presence of attractive models
Michal Mikolaj Stefanczyk Katarzyna Lizak Marta Kowal Agnieszka Sorokowska 《British journal of psychology (London, England : 1953)》2022,113(3):739-757
Disgust sensitivity differs among men and women, and this phenomenon has been observed across numerous cultures. It remains unknown why such sex differences occur, but one of the reasons may relate to differences in self-presentation. We tested that hypothesis in an experiment comprising 299 participants (49% women) randomly allocated into three groups. Each group completed the Three Domains Disgust Scale (TDDS) and rated how disgusting they found olfactory, visual, gustatory, and tactile disgust elicitors either when a male experimenter was present, a female experimenter was present, or no experimenter was present. We hypothesised that male participants in the female experimenter group would declare decreased levels of disgust sensitivity, and female participants in the male experimenter group would declare increased levels of disgust sensitivity. Results showed that despite sex differences in pathogen and sexual disgust, attractive experimenters did not evoke any differences in declared disgust across groups with one exception–both men and women self-presented as more sensitive to sexual disgust in the presence of the female experimenter. We discuss our findings in the light of evolutionary and social theories. 相似文献
