Developmental and comparative studies of the ability to understand communicative intentions using object-choice tasks raise questions concerning the semiotic properties of the communicative signals, and the roles of rearing histories, language and familiarity. We adapted a study by Tomasello, Call, and Gluckman (1997), in which a “helper” indicated the location of a hidden reward to children of three ages (18, 24, and 30 months) and to four chimpanzees, by means of one of four cues: Pointing, Marker, Picture and Replica. For the chimpanzees, we controlled for familiarity by using two helpers, one unfamiliar and one highly familiar. Even 18-months performed well on Pointing and Marker, while only the oldest group clearly succeeded with Picture and Replica. Performance did not correlate with scores for the Swedish Early Communicative Development Inventory (SECDI). While there were no positive results for the chimpanzees on the group level, and no effect of familiarity, two chimpanzees succeeded on Pointing and Marker. Results support proposals of a species difference in understanding communicative intentions, but also highlight the need to distinguish these from the complexity of semiotic vehicles and to consider both factors. 相似文献

Objective: To investigate how the effects of a group-based intervention program (MoVo-LISA) on exercise behaviour were mediated by cognitive variables. Different causal models mapping the short-term (adoption) and long-term (maintenance) intervention effects were tested using path analyses. Design: N?=?220 in-patients of a rehabilitation clinic were assigned to an usual care or intervention group (quasi-experimental design). Questionnaire-based assessment was conducted at baseline; discharge; and at six weeks, six months and 12 months post discharge. Measures: The potential mediator variables were outcome expectations, self-efficacy, strength of goal intention (intention strength), self-concordance, action planning and barrier management. Results: Observed intervention effects on exercise behaviour (p?<?0.05) were mediated by intention strength at the adoption and maintenance stages, by action planning only at the adoption, and by barrier management only at the maintenance stage. Self-efficacy and outcome expectations were only indirectly involved in these mediations by affecting intention strength and self-concordance. Conclusion: This is the first study to track the cognitive mediation processes of intervention effects on exercise behaviour over a long time-period by differentiating the adoption and maintenance stages of behaviour change. The findings emphasise the importance of deconstructing intervention effects (modifiability vs. predictive power of a mediator) to develop more effective interventions. 相似文献

Results are presented for suitability screening conducted by the United States Air Force during basic military training. The Lackland Behavioral Questionnaire has been used operationally since 2007, and its use has led to an increase in predictive validity. For the prediction of outcomes during the first 4 years of service, one can identify trainees with a 49% likelihood of being separated for unsuitability and a 56% likelihood of being diagnosed with a mental disorder. A formal suitability screening program allows referrals and recommendations to be made using a combination of empirical evidence and clinical judgment. 相似文献

Using a diverse urban sample of immigrant adolescents in the United States (N = 345) followed from 10th grade (Mage = 15.69) to 12th grade, this study examined the extent to which ecological assets (i.e., community connections and social network resources) predicted civic commitments (i.e., community engagement, social responsibility) as potentially mediated by fair society beliefs. The authors also examined whether ethnicity and generation status moderated these associations. As hypothesized, fair society beliefs were higher and predicted greater civic commitments only among Asian youth. Ecological assets were associated with greater civic commitments for all participants; these links were primarily direct for Latino immigrants and indirect (via fair society beliefs) for Asian youth. First-generation immigrants had more ecological assets and were more civically committed, however social network resources predicted fair society beliefs and community engagement only for second-generation youth. These differences indicate that immigrant youth are best understood as a heterogeneous group and suggest the need for further investigation of cultural variations in civic developmental processes. 相似文献

Previous work has examined how messages communicated to students prior to high-stakes exams, that emphasise the importance of avoiding failure for subsequent life trajectory, may be appraised as threatening. In two studies, we extended this work to examine how students may also appraise such messages as challenging or disregard them as being of little relevance. In study one we piloted a questionnaire with students studying for their school leaving qualification in maths. Threat appraisals were correlated with low academic self-efficacy, high attainment value and low intrinsic value. Challenge appraisals were correlated with high academic self-efficacy, and high intrinsic, extrinsic and attainment value. In study two, we manipulated attainment value and academic self-efficacy in a series of vignettes. High value and high academic self-efficacy lead to challenge appraisals, high value but low academic self-efficacy lead to threat appraisals and low value lead to a disregarding of messages. These findings show that the relevance of messages is judged on attainment value in a primary appraisal and as a challenge or threat in a subsequent appraisal, based on the expectation of success or failure. These findings also highlight how the effectiveness of such messages may differ depending on student characteristics. 相似文献

Social competence, i.e. appropriate or effective social functioning, is an important determinant of quality of life. Social competence consists of social skills, social performance and social adjustment. The current paper reviews social skills, in particular emotion recognition performance and its relationship with social adjustment in children with brain disorders. In this review, normal development and the neuro-anatomical correlates of emotion recognition in both healthy children and adults and in various groups of children with brain disorders, will be discussed. A systematic literature search conducted on PubMed, yielded nine papers. Emotion recognition tasks were categorized on the basis of task design and emotional categories to ensure optimal comparison across studies before an explorative meta-analysis was conducted. This meta-analytic review suggests that children with brain disorders show impaired emotion recognition, with the recognition of sad and fearful expressions being most impaired. Performance did not seem to be related to derivative measures of social adjustment. Despite the limited number of studies on a variety of brain disorders and control groups, outcomes were quite consistent across analyses and corresponded largely with the existing literature on development of emotion recognition in typically developing children. More longitudinal prospective studies on emotion recognition are needed to gain insight into recovery and subsequent development of children with distinct brain disorders. This will aid development, selection and implementation of interventions for improvement of social competence and quality of life in children with a brain disorder. 相似文献
