Research in the area of sex differences in coalitional behavior has produced inconsistent results that may be partially resolved through an examination of personality and attitudinal differences between males and females. The responses of males and females to the Shure and Meeker Personality/Attitude Schedule were analyzed and the sexes differed in their elevation on six major factors. A subsample of each sex participated in a coalition game situation. Four of the six personality and attitude factors were related to prenegotiation stage indices of coalition formation. It was suggested that the role of sex differences in coalitional behavior may be mediated by sex role socialization differences.  相似文献

An experimental model tested the mediating function of interpersonal cognitive problem solving skills on behavioral adjustment in preschool and kindergarten children. Relative to controls, nursery-trained youngsters improved in three such skills, kindergarten-trained in two. In both the nursery- and kindergarten-trained groups, increased ability to conceptualize alternative solutions to interpersonal problems significantly related to improved social adjustment. Consequential thinking also emerged as a clear behavioral mediator, especially among kindergarten-aged youngsters. Improvement in behavior could not, however, be attributed to change in causal thinking skills. Having identified two significant behavioral mediators in young children, a beginning has been made to isolate specific thinking skills, which, if enhanced, can contribute to healthy social adjustment and interpersonal competence at an early age.  相似文献

Forty English-French bilinguals divided into equal numbers of nonfluent and fluent subjects took part in a dichotic listening test involving both intralingual and interlingual conditions. No difference in lateralization was found between primary and secondary language in either condition. In the intralingual condition, however, fluent bilinguals showed a significantly lower right ear advantage than did their nonfluent counterparts. In the interlingual condition, French-dominant subjects were found to be more ambilateral than English-dominant subjects, while both groups tended to respond preferentially to French words. These results suggest that growing bilingual proficiency does increase left ear/right hemisphere participation, but in intralingual situations only. Moreover, when both languages are contrasted, French appears to be more salient than English.  相似文献

阈下语义之间能否进行整合,最近的研究给出了不同的结果。当多个阈下语义词语同时呈现时显示出无意识语义整合效应,但是当序列呈现时没有观察到无意识整合效应。本研究在保留同时呈现方法优点(不同空间呈现位置)的情况下研究了序列呈现的不同汉字词语之间能否产生无意识语义类别关系整合。在实验1中,两个相同或不同类别的词语作为阈下启动刺激先后在两侧呈现,且第一个词语消失后第二词语马上出现,结果显示出无意识语义类别整合效应。实验2延长了两个阈下启动词语之间的时间间隔,结果未发现无意识语义类别整合效应。另外,实验3进一步排除了实验1中第一个启动词语的视觉残留,结果也未观察到显著的无意识语义类别整合效应,说明实验1中观察到的无意识整合效应是视觉残留所致。综合三个实验结果表明,两个阈下词语之间的语义类别一致性关系只有在同时呈现这种特殊条件下才能进行无意识整合加工,说明了短时间维度对于无意识语义关系整合的重要性。  相似文献

Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus.  相似文献

A growing body of experimental work highlights the potential value of unstructured, interactive, or spontaneous motions, including gestures, dance, shifting body postures, physical object-manipulation, drawing, etc. to favorably impact creative performance. However, despite these favorable findings, to our knowledge, no systematic review has been conducted to explore the totality of evidence for embodied activities in this arena. Thus, the objective of this paper was to systematically evaluate the potential effects of embodied experimental manipulations on traditionally assessed creativity outcomes. A systematic review was conducted utilizing PubMed, PsychInfo, Sports Discus, and Google Scholar databases. The 20 studies evaluated employed a variety of methodological approaches regarding study design, embodied manipulation, and selection of specific creativity outcomes. Despite these variations, embodied movement robustly enhanced creativity across nearly all studies (90%), with no studies showing a detrimental effect. Based on the evaluation of the studies reviewed, several common themes emerged. These included the relevance of symbolic metaphors and distributed embodied cognitions, selection of embodied modality, specific measurement considerations, as well as the importance for implementing true, inactive control conditions in embodied creativity research. This review expands on these findings and places them in the context of improving future embodied creativity research.  相似文献

Christian Scientists’ rejection of conventional medical practices has generated considerable controversy. Using insights from theories of subcultural identity and cultural repertoires, we analyze elite discourse and adherent narratives from 20 Christian Scientists to examine how this nonmedicalized religion engages the challenges posed by the highly medicalized character of American society. The writings of Christian Science founder Mary Baker Eddy primarily exhibit a critical posture toward conventional medicine, although conciliatory language is also evident in these same works. These discursive nuances provide Christian Science adherents with latitude in negotiating health and illness in their everyday lives. Interview data reveal that negotiated health practices are particularly evident in three domains: using prayer as a means of seeking divine guidance, developing metaphysical competency as a healer, and weighing options based on legal mandates for seeking medical treatment. We conclude by specifying the implications of our findings and identifying directions for future research.  相似文献

We propose that religious service attendance (RSA) serves as a coping resource by providing a sense of continuity. As a source of continuity, and per the stress‐support matching hypothesis, RSA should consistently buffer the negative mental well‐being impacts of stressors related to discontinuity—the disruption of regular routines and relationships. Most, but not all, of the relevant previous studies we reviewed found that RSA served as an effective buffer for the negative mental health impacts of discontinuity stressors (such as unemployment, terminated relationships, etc.). This variability in previous findings warranted a formal exploration of the relationship between RSA and specific stressors. To that end, we conducted a series of OLS regression path analyses on a sample of Americans age 40 and older (N = 2,579). RSA was found to consistently buffer the negative impact of discontinuity stressors on mental well‐being but failed to do so for other stressors. Overall, our observations are (a) consistent with the stress‐support matching hypothesis, (b) suggest that RSA is particularly effective for reducing the negative impacts of discontinuity stressors, and (c) found no instance in which RSA exacerbated (i.e., made more severe) the effects of life event stressors on mental well‐being.  相似文献

All people share a need for safety. Yet people’s pursuit of safety can conflict when it comes to guns, with some people perceiving guns as a means to safety and others perceiving guns as a threat to safety. We examined this conflict on a U.S. college campus that prohibits guns. We distinguished between people (N = 11,390) who (1) own a gun for protection, (2) own a gun exclusively for reasons other than protection (e.g., collecting, sports), and (3) do not own a gun. Protection owners felt less safe on campus and supported allowing guns on campus. They also reported that they and others would feel safer and that gun violence would decrease if they carried a gun on campus. Non-owners and non-protection owners felt the reverse. The findings suggest that protection concerns, rather than gun-ownership per se, account for diverging perceptions and attitudes about guns and gun control.  相似文献
