We studied whether the origins of math anxiety can be related to a biologically supported framework of stress induction: (un)controllability perception, here indicated by self‐reported independent efforts in mathematics. Math anxiety was tested in 182 children (8‐ to 11‐year‐olds). Latent factor modeling was used to test hypotheses on plausible causal processes and mediations within competing models in quasi‐experimental contrasts. Uncontrollability perception in mathematics, or (in)dependence of efforts, best fit the data as an antecedent of math anxiety. In addition, the relationship of math anxiety with gender was fully mediated by adaptive perception of control (i.e. controllability). That is, young boys differ from girls in terms of their experience of control in mathematics learning. These differences influence math anxiety. Our findings are consistent with recent suggestions in clinical literature according to which uncontrollability makes women more susceptible to fear and anxiety disorders.

Why are infants able to anticipate occlusion events and other people's actions but not the movement of self-propelled objects? This study investigated infant and adult anticipatory gaze shifts during observation of self-propelled objects and human goal-directed actions. Six-month-old infants anticipated self-propelled balls but not human actions. This demonstrates that different processes mediate the ability to anticipate human actions (direct matching) versus self-propelled objects (extrapolation).  相似文献

The past two decades have seen a tremendous surge in scientific interest in the extent to which certain types of training—be it aerobic, athletic, musical, video game, or brain trainer—can result in general enhancements in cognitive function. While there are certainly active debates regarding the results in these domains, what is perhaps more pressing is the fact that key aspects of methodology remain unsettled. Here we discuss a few of these areas including expectation effects, test–retest effects, the size of the cognitive test battery, the selection of control groups, group assignment methods, difficulties in comparing results across studies, and in interpreting null results. Specifically, our goal is to highlight points of contention as well as areas where the most commonly utilized methods could be improved upon. Furthermore, because each of the sub-areas above (aerobic training through brain training) share strong similarities in goal, theoretical framework, and experimental approach, we seek to discuss these issues from a general perspective that considers each as members of the same broad “training” domain.  相似文献

Both perceived stress and negative recurrent thinking (rumination and worry) have been associated with depressive symptoms. However, no research to date has investigated the association between perceived stress and negative recurrent thinking. In the present study we aimed to explore whether perceived stress and negative recurrent thinking are associated and whether negative recurrent thinking moderates the relationship between perceived stress and depressive symptoms. A convenience sample of 273 undergraduate students completed the Perceived Stress Scale, the Ruminative Responses Scale-10, the Penn State Worry Questionnaire and the Hospital Anxiety and Depression Scale 2 weeks prior to sitting mid-year examinations. Correlation analyses showed that perceived stress, rumination and worry were positively and significantly associated with depressive symptoms and that perceived stress was positively and significantly associated with rumination and worry. A moderation analysis confirmed that negative recurrent thinking moderated the relationship between perceived stress and depressive symptoms. The implications of these findings are discussed.  相似文献

Siblings of children and young people with a chronic illness are at increased risk of poor psychological functioning. A number of studies have attempted to implement and evaluate interventions targeting the psychological well-being of this at-risk group. This systematic review summarises the evidence regarding psychological functioning of siblings following an intervention targeting their well-being. The meta-analysis considered behaviour and knowledge, two of the most frequently studied outcomes. The following databases were used: PsycINFO, EMBASE, CINAHL, PubMed, Scopus and Web of Science. Seventeen studies were eligible to be included in the systematic review and eight in the meta-analysis. Results from the systematic review reflected the inconsistency of intervention evaluations in this area with a high level of heterogeneity and a total of 23 outcomes considered across the 17 included studies. The meta-analysis estimated effect sizes using a standardised mean difference (SMD) approach. Pre-post analysis suggested significant improvement in behavioural outcomes and knowledge of their sibling’s health conditions with a SMD of ? 0.44 [95% CI (? 0.6, ? 0.29); p = 0.000] and 0.69 [(95% CI = 0.42, 0.96); p = 0.000], respectively. The SMD was not significant for behavioural outcomes when considering treatment–control studies. In conclusion, the findings suggest interventions for well-being have a positive effect on the psychological functioning of siblings of children and young people with a chronic illness, but their specificity needs to be established. There is a need for further, more methodologically robust research in this area.  相似文献
