In explanation-based learning (EBL), domain knowledge is leveraged in order to learn general rules from few examples. An explanation is constructed for initial exemplars and is then generalized into a candidate rule that uses only the relevant features specified in the explanation; if the rule proves accurate for a few additional exemplars, it is adopted. EBL is thus highly efficient because it combines both analytic and empirical evidence. EBL has been proposed as one of the mechanisms that help infants acquire and revise their physical rules. To evaluate this proposal, 11- and 12-month-olds (n?=?260) were taught to replace their current support rule (that an object is stable when half or more of its bottom surface is supported) with a more sophisticated rule (that an object is stable when half or more of the entire object is supported). Infants saw teaching events in which asymmetrical objects were placed on a base, followed by static test displays involving a novel asymmetrical object and a novel base. When the teaching events were designed to facilitate EBL, infants learned the new rule with as few as two (12-month-olds) or three (11-month-olds) exemplars. When the teaching events were designed to impede EBL, however, infants failed to learn the rule. Together, these results demonstrate that even infants, with their limited knowledge about the world, benefit from the knowledge-based approach of EBL. 相似文献

The developmental trajectories of maladaptive perfectionism, along with their consequences and origins, were examined in middle childhood. A sample of Singaporean children and their parents (N = 302) were recruited for a longitudinal study when the children were 7 years old. Subsequent follow‐up assessments were made at ages 8, 9, and 11. A multimethod approach was adopted where parent reports, child reports, and observational data on a dyadic interaction task were obtained. Using latent class growth modeling, four distinct classes were obtained for critical self‐oriented perfectionism (SOP‐C), whereas two classes emerged for socially prescribed perfectionism (SPP). Children with high and/or increasing SOP‐C and SPP trajectories constituted 60% and 78% of the sample, respectively. For both SOP‐C and SPP, trajectories with high initial status were associated with higher internalizing and externalizing symptoms. Parental intrusiveness and negative parenting predicted high and/or increasing SOP‐C trajectories, whereas the child temperament dimension of surgency predicted high SPP trajectory. Both SOP‐C and SPP trajectories tended to co‐occur, suggesting a mutually reinforcing process. This study yields important findings that help advance current understanding of the emergence and developmental pathways of maladaptive perfectionism in children. 相似文献

Consensus studies from 4 cultures--in Belgium, the Czech Republic, Estonia, and Germany--as well as secondary analyses of self- and observer-reported Revised NEO Personality Inventory (NEO PI-R) data from 29 cultures suggest that there is a cross-culturally replicable pattern of difference between internal and external perspectives for the Big Five personality traits. People see themselves as more neurotic and open to experience compared to how they are seen by other people. External observers generally hold a higher opinion of an individual's conscientiousness than he or she does about him- or herself. As a rule, people think that they have more positive emotions and excitement seeking but much less assertiveness than it seems from the vantage point of an external observer. This cross-culturally replicable disparity between internal and external perspectives was not consistent with predictions based on the actor-observer hypothesis because the size of the disparity was unrelated to the visibility of personality traits. A relatively strong negative correlation (r = -.53) between the average self-minus-observer profile and social desirability ratings suggests that people in most studied cultures view themselves less favorably than they are perceived by others. 相似文献

In a large sample of early adolescents (T2: n = 1023; M age = 13.51; 55.5% girls) it was investigated whether the effects of parental and peer acceptance and rejection on psychopathology
(externalizing and internalizing problems) remain when taking into account both contexts simultaneously. Moreover, we examined
whether acceptance in one context can buffer rejection in the other. It was found that when analyzing peer and parent effects
simultaneously (1) the protective effect of parental acceptance and the risk effect of peer rejection were diminished; (2)
the protective effect of peer acceptance and the risk-effect of parental rejection remained strong; and (3) peer acceptance
buffered parental rejection but parental acceptance did not buffer peer rejection. The results imply that the parent and peer
contexts are interdependent. Implications and directions for future research are given. 相似文献

In this study a homophily selection hypothesis was tested against a default selection hypothesis, to answer whether preferred
and realized friendships of highly aggressive boys differed. In a large peer-nomination sample, we assessed who highly overt
aggressive, low prosocial boys (n = 181) nominated as friends (preferred friendships) and who among the nominated friends reciprocated the friendship (realized
friendships). These preferred and realized friendships were compared with those of less aggressive (n = 1,268) and highly aggressive but also prosocial boys (bi-strategics; n = 55). Results showed that less aggressive boys preferred peers low on aggression, whereas highly aggressive and bi-strategic
boys preferred peers not particular high or low on aggression. In line with default selection, highly aggressive boys ended
up with aggressive peers even though that was not their preference. In general, received support proved an important determinant
of highly aggressive, bi-strategic, and less aggressive boys’ preferred and realized friendships. Especially highly aggressive
boys preferred emotionally supportive friends, but ended up with the least supportive peers. In sum, for friendships of highly
overt aggressive boys, the evidence favors default selection over homophily selection. 相似文献

中国和韩国历史上的文化交流从未中断过。虽然韩国与中国西南地区的自然环境有着很多不相同之处,但两国的虎图腾崇拜文化却呈现出息息相通的局面。韩民族文化中的虎图腾崇拜现象,不仅反映了韩国土著文化之根的真正所在,也体现了韩民族与中国西南少数民族之间的文化同源关系。 相似文献

A holistic method for eliciting and evaluating group cognition was introduced and tested. In the study, 359 undergraduate students were assigned to 72 groups, consisting of 4 to 6 members who worked on research projects lasting for 14 weeks. In order to evaluate the way groups represent the specific knowledge related to their tasks, we used a conceptual mapping technique. Conceptual mapping proved to be a fruitful way to understand the way groups represent their knowledge. The conceptual maps were stable in time and had explanatory power for groups' performance. 相似文献

国际合作是构筑世界和平的一条重要渠道,也是国际政治的核心议题。主流国际关系理论认为,国际合作是一种以达成利益分配为基准的获利性的交往行为,因而合作难以达成抑或充满变数。女性主义对国际合作有着特殊的认知和偏好,它试图融入主流国际关系理论的过程及其对国际政治现实的认知均彰显了强烈鲜明的合作观念。女性主义以其独特的视角对主流国际关系理论进行批判并赋予国际合作以稳定性和牢固性。只有两种性别伦理的合作偏好有机结合起来,才能最终促进国际合作,实现世界和平。 相似文献
