In 2 experimental studies, social indispensability and upward social comparison were contrasted as potential triggers of motivation gains of inferior group members. Using a cognitive task in a computer‐supported environment, individual work was compared with conditions that enabled upward comparison only (coaction), or both upward comparison and social indispensability (conjunctive task). Moreover, working conditions (face‐to‐face vs. anonymous) and partner‐related performance feedback (contemporaneously vs. post‐task) were manipulated as potential moderators. Results revealed motivation gains only when partner feedback was contemporaneously available. In this case, upward‐comparison effects could be demonstrated during coaction. However, when participants' contribution determined a group outcome, their motivation was additionally increased, demonstrating social indispensability effects. Finally, motivation gains were generally higher during face‐to‐face compared to anonymous work. 相似文献

The authors explored the influence of task content and the menstrual cycle phase on working memory (WM) performance. They addressed the content specificity of WM in the framework of evolutionary psychology, proposing a hormone-mediated adaptive design governing face perception. The authors tested 2 groups of healthy young women (n = 66 women with regular menstrual cycle, n = 27 oral contraceptive users) on a WM task with adult male or infant face photographs. Analyses of variance showed significant interaction between task content and estrogen level. Women were more efficient in solving the male faces task during high-estrogen phase of the cycle than during low-estrogen phase. No differences were found in the efficacy of solving the infant faces task between different phases of the cycle. Results suggest content-specific activational effects of estrogen on the WM performance and are consistent with the notion of a hormonal mechanism underlying adaptive shifts in cognition related to mating motivation. 相似文献

Changes in the labour market require people to show more self‐management than before if they want to succeed. The present research was conducted to analyse the nomological network of general self‐management strategies (i.e. selection of goals; optimization as implementation of goal‐pursuing behaviour), specific self‐management strategies (i.e. career planning) and central indicators of career success, i.e. objective career success (pay, position), self‐referent subjective success (career satisfaction), and other‐referent career success (comparative judgment). In a large sample of professionals (N=1,185), we found in support of our hypotheses that the generalized strategy of optimization was linked to the domain‐specific strategy of career planning, and that domain‐specific career planning was directly linked to all outcome measures. The generalized strategy of optimization was directly linked to subjective success, but only indirectly to objective success. The link from self‐management to subjective success was independent of objective success. Most interestingly, and in accord with our social comparison assumption, objective success was more closely linked to other‐referent success than to self‐referent success. Implications for career research and career counselling are discussed. 相似文献

With the increasing popularity in the use of brain imaging on antisocial individuals, an increasing number of brain imaging studies have revealed structural and functional impairments in antisocial, psychopathic, and violent individuals. This review summarizes key findings from brain imaging studies on antisocial/aggressive behavior. Key regions commonly found to be impaired in antisocial populations include the prefrontal cortex (particularly orbitofrontal and dorsolateral prefrontal cortex), superior temporal gyrus, amygdala-hippocampal complex, and anterior cingulate cortex. Key functions of these regions are reviewed to provide a better understanding on how deficits in these regions may predispose to antisocial behavior. Objections to the use of imaging findings in a legal context are outlined, and alternative perspectives raised. It is argued that brain dysfunction is a risk factor for antisocial behavior and that it is likely that imaging will play an increasing (albeit limited) role in legal decision-making. 相似文献

Analysis of acoustic interactions between animals in active choruses is complex because of the large numbers of individuals present, their high calling rates, and the considerable numbers of vocalizations that either overlap or show close temporal alternation. The authors describe a methodology for recording chorus activity in bullfrogs (Rana catesbeiana) using multiple, closely spaced acoustic sensors that provide simultaneous estimates of sound direction and sound characteristics. This method provides estimates of location of individual callers, even under conditions of call overlap. This is a useful technique for understanding the complexity of the acoustic scene faced by animals vocalizing in groups. 相似文献

The authors investigated in an observational study the consequences of the presence of litter sisters on the social interactions and on reproductive performance of young female European rabbits (Oryctolagus cuniculus) from a population living under seminatural conditions. In early winter, when all young females were settled in a social group, they were characterized by the presence or absence of litter sisters in their groups. Females with litter sisters in their groups displayed significantly more positive social interaction with females of their social group compared to females without sisters, whereas this difference was mainly due to the high frequency of positive social interactions among the respective sisters. Such differences between the females of both categories were already apparent during the animals' juvenile phase, before the females integrated into a particular group: females which later had litter sisters in their group showed more positive social behavior than females which later no longer had litter sisters. During their first breeding season, females with litter sisters present generally started to breed earlier by an average of 14 days. A more favorable social environment might have possibly facilitated the earlier onset of breeding in females with present litter sisters by attenuating the negative consequences of stress. 相似文献

Guided by the theory of planned behavior, this analysis explores the communication skills of women who had genetic testing for BRCA1 and BRCA2. The key outcome was intention to tell test results to adult first-degree relatives. The theory predicts that global and specific attitudes, global and specific perceived social norms, and perceived control will influence the communication of genetic test results. A logistic regression model revealed that global attitude (p < .05), specific social influence (p < .01), and perceived control (p < .05) were significant predictors of intention to tell. When gender and generation of relatives were added to the regression, participants were more likely to convey genetic test results to female than to male relatives (p < .05) and were also more likely to communicate test results to children (p < .01) or siblings (p < .05) than to parents. However, this association depended on knowing the relative's opinion of genetic testing. Intention to tell was lowest among participants who did not know their relative's opinion. These results extend the theory of planned behavior by showing that gender and generation influence intention when the relative's opinion is unknown. 相似文献

As we navigate a world full of uncertainties and risks, dominated by statistics, we need to be able to think statistically. Very few studies investigating people's ability to understand simple concepts and rules from probability theory have drawn representative samples from the public. For this reason we investigated a representative sample of 1000 Swiss citizens, using six probabilistic problems. Most reasoned appropriately in problems representing pure applications of probability theory, but failed to do so in approximations of real‐world scenarios – a disparity we replicated in a sample of first‐year psychology students. Additionally, education is associated with probabilistic numeracy in the former but not the latter type of problems. We discuss possible reasons for these task disparities and suggest that gaining a comprehensive picture of citizens' probabilistic competence and its determinants requires using both types of tasks.

German dialect geography developed, inter alia, as a means to compensate the shortcomings of the Young Grammarians’ approach
to language. In contrast to the latter, it was conceived of to be a sociolinguistic project, constituting thereby one link
between the development of Soviet and German linguistics. The article tries to answer such questions as who initially participated
in transferring ideas of German dialectology to the Soviet Union and what kind of motivations underlay those transfers. Combining
biographical facts with systematic aspects, the article surveys the filiations of some productive ideas with the help of archival
sources, i.e. letters of the Soviet scholars Dinges (1891–1932) and Viktor Žirmunskij (1891–1971). Finally, I try to single
out the elements in Žirmunskij dialect geography, which are specifically sociolinguistic.
