Enhanced attentional capture in trait anxiety

Attentional Control Theory (ACT) proposes that anxiety is specifically associated with more attentional distraction by salient stimuli. Moreover, there is some suggestion that worry is one mechanism whereby anxiety impairs attentional control. However, direct evidence for these hypotheses is lacking. In the current study we addressed limitations of previous work by examining the relationships between trait anxiety and worry and attentional distraction by a salient, task-irrelevant color singleton in a visual search task. Results revealed that trait anxiety, but not worry, was related to increased attentional distraction (i.e., capture) by the color singleton. The current results suggest that anxiety is associated with a general enhancement of bottom-up processes involved in motivational significance detection.

有氧运动对记忆的影响及其神经生物学机制

有氧运动是氧气充足时运用大型肌肉群进行有节奏的持续运动。有氧运动可以加快工作记忆任务中的反应速度;在记忆编码前和记忆巩固阶段进行高强度有氧运动有助于提升情景记忆;高强度有氧运动可以促进内隐记忆。有氧运动可以促进神经营养因子的产生,引起长时程增强,激活海马等与记忆相关的脑区并促进神经元再生。未来可探究有氧运动开始和持续时间的影响、有氧运动强度和认知参与的影响、有氧运动对不同年龄性别群体的影响以及脑源性神经营养因子的中介作用,从而深入揭示有氧运动对记忆的影响及其神经生物学机制。     

心理资本: 本土量表的开发及中西比较

开发了本土心理资本量表, 并将之与西方量表进行了比较。结果显示, 本土心理资本构念具有二阶双因素结构: 事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)与人际型心理资本(谦虚诚稳、包容宽恕、尊敬礼让与感恩奉献)。事务型心理资本与西方心理资本基本相似, 人际型心理资本则具有本土文化气息。本土量表具有良好的效标关联效度, 人际型心理资本、事务型心理资本和任务绩效、周边绩效、工作满意度、工作投入及组织承诺显著正相关, 人际型心理资本与传统性、相依我正向关系显著。相比西方量表, 本土量表的信效度更好, 对工作绩效有更强的解释能力, 尤其是对周边绩效。建议进行心理资本研究时应充分考虑中西文化差异, 对组织而言, 则应重视对雇员本土心理资本各要素的开发与管理。     

Naïve Realism,Seeing Stars,and Perceiving the Past

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist view of time, and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past.     

Visual, kinaesthetic and cross-modal development: relationships to motor skill development

The ability of children between the ages of 5 and 10 years to match the length of lines within and between the modalities of vision and kinaesthesis was studied. No evidence was found for specific increases in cross-modal skill which could not be explained in terms of within-modal development. Performance in the perceptual task was related to measures of developing motor skill in the children. Substantial relationships were found between performance on the within-modal tasks and motor skill, but no significant relationships were found between cross-modal measures and motor skill development. It is concluded that the development of cross-modal integration is not a major determinant of motor skill development.
