The aim of this study was to investigate possible interactive links between theory of mind (ToM), moral disengagement and relational aggression, using a moderated mediation analysis, with gender as a moderator, in a sample of 120 Greek preadolescents. Results indicated that relational aggression was significantly positively associated with moral disengagement and negatively with ToM. Moderated mediation analyses indicated that boys with deficient ToM were more likely to morally disengage from their actions which in turn resulted in relational aggression, while poor ToM was directly linked to relational aggression only for preadolescent girls. Moral disengagement had a direct effect on relational aggression only for boys, while ToM was found to partially mediate the relationship between moral disengagement and relational aggression only for girls. The results emphasize that the co‐morbid effects of socio‐cognitive factors should be taken into consideration when relational aggression is explored.  相似文献

The study was designed to determine whether outer-directedness, measured by glances at E during object assembly tasks administered according to the Turnure and Zigler (1964) procedure, predicts changes in preschoolers' Binet IQs over 6 months. With MA as a covariate to control for the small but significant relationship betweeen glances and developmental level, an ANOCOVA showed a significant interaction resulting from increases in the IQs of non-outer-directed Ss and declines in the IQs of outer-directed Ss. Glances at E's puzzle while S assembled his own were unrelated to glances at E or to IQ changes, but, unlike glances at E, were significantly related to improvements in performance from puzzle 1 to puzzle 2.  相似文献

A report is given on Canadian hospital library standards as recently developed and incorporated in a new Guide to Hospital Accreditation, 1977. The new Canadian standards are compared with MLA recommendations to the Joint Commission on Accreditation of Hospitals. Their development is sketched and the contribution from Quebec of a model of hospital classification is examined. This model provides differential minimal library standards based on the function of the hospital rather than on its size alone. Use of these minimal standards as a practical means of developing hospital libraries is discussed and their implications for accreditation visits are underlined.  相似文献
