AbstractThe purpose of sharing is to construct equivalent sets, making it an ideal context for analysing important quantitative concepts such as counting, equivalence and cardinality. Two studies analysed how four- and five-year-olds shared blocks in equal sharing and reciprocity conditions and their number inferences about one set after counting the other. The researcher asked children to share double and single blocks between two characters. They succeeded more in building equivalent shares in an equal sharing than reciprocity condition. Most children who shared correctly also made appropriate number inferences. To examine whether perceptual cues helped children share the blocks, a second study used Canadian $1 and $2 coins. A double block is twice the size of a single, whereas there is no visual cue about the value relation between coins because they are the same size. Unexpectedly, children shared equally well with blocks and coins, and most children made number inferences. 相似文献

Prior research has indicated that shy adolescents are more motivated to form friendships online than to form friendships offline. Little is known about whether having friendships found exclusively online may impact self‐esteem and forming offline friendships for these adolescents. This study therefore aimed to provide insight into the moderating role of shyness in the longitudinal interplay between friendships in online and offline contexts in early adolescence. Adolescents and their friends (193 girls, 196 boys; Mage = 13.29) were followed with three consecutive measurements with intervals of eight months. Results showed that particularly for shy adolescents, having friends exclusively online predicted increases in self‐esteem. Self‐esteem, in turn, was found to predict forming more friendships found both offline and online and forming more friendships found exclusively offline. Thus, findings supported the social compensation perspective that shy adolescents may benefit from having friends exclusively online, as these friendships may increase self‐esteem, thereby facilitating the formation of friendships found partially and completely offline.

Job performance criterion models have become more popular and more often investigated. The current research adds to this literature by testing performance models focusing on ability and personality predictors of task and citizenship job performance. Air traffic controllers (N = 928) completed cognitive ability and personality predictor measures, were administered a performance test assessing two possible mediators, and were evaluated using supervisor and peer ratings of two task performance, one citizenship performance, and an overall performance dimension. Path analyses largely confirmed that ability predicts primarily task performance and personality predicts primarily citizenship performance. The mediation related to task knowledge and skill on the task performance side was confirmed, and the overall fit of the performance models was quite good. Discussion focuses on how the present research furthers progress toward mapping relations among individual differences and individual performance constructs, beyond using overall performance as the endogenous performance variable. 相似文献

Research in healthy controls has found that mood influences cognitive processing via level of action identification: happy moods are associated with global and abstract processing; sad moods are associated with local and concrete processing. However, this pattern seems inconsistent with the high level of abstract processing observed in depressed patients, leading Watkins (2008, 2010) to hypothesise that the association between mood and level of goal/action identification is impaired in depression. We tested this hypothesis by measuring level of identification on the Behavioural Identification Form after happy and sad mood inductions in never-depressed controls and currently depressed patients. Participants used increasingly concrete action identifications as they became sadder and less happy, but this effect was moderated by depression status. Consistent with Watkins' (2008) hypothesis, increases in sad mood and decreases in happiness were associated with shifts towards the use of more concrete action identifications in never-depressed individuals, but not in depressed patients. These findings suggest that the putatively adaptive association between mood and level of identification is impaired in major depression. 相似文献

Increased negative thinking in response to sad mood states has been identified as a marker of depression risk. The present study examined whether polymorphisms of the serotonin transporter (5-HTTLPR) gene were associated with the tendency to endorse negative cognition after sad or neutral mood inductions in a healthy college student sample. Non-depressed participants were genotyped for the 5-HTTLPR and then viewed films designed to elicit a sad mood (n=30) or a neutral mood (n=23). Analyses indicated that individuals homozygous for the short 5-HTTLPR allele endorsed more negative cognition following a sad mood induction than individuals homozygous for the long 5-HTTLPR allele. Negative cognition did not vary as a function of 5-HTTLPR genetic status in the neutral mood condition. These preliminary results suggest that genetic variation of the serotonin transporter may contribute to depression vulnerability via a tendency to think more negatively in response to events that elicit sad mood. 相似文献

If derogation of out-groups serves the function of bolstering self-esteem, it is possible that this effect can be counteracted by means of existential relief. Two variables were presented in a 2 × 2 factorial to a population of primarily college students: a mortality salience (MS) variable and an afterlife variable, in which participants read “scientific” accounts that either supported or denied the existence of a literal afterlife. Homonegativity was utilised as a dependent measure of out-group derogation. In the predicted manner, mortality salience and afterlife variables interacted to predict significantly different levels of homonegativity. When participants were subconsciously primed with MS, their psychological need to derogate dissimilar others was significantly lowered if they were assured of an afterlife. These results demonstrate that the effects of MS can be attenuated by presenting existential relief through assurance of literal afterlife. 相似文献
