Visual awareness and the on-line modification of action.

An influential theory of visually guided action proposes that (a) conscious perception of target displacement disrupts on-line action and (b) small target perturbations are inconsequential, provided the participant is unaware of them. This study examined these claims in a study of rapid aiming movements to targets. Novel features included on-line verbal reports of target displacement, and the factorial combination of small versus large displacements occurring near peak saccadic velocity or 100 ms later. Although awareness of target displacement had no effect on movement kinematics, even small target displacements near peak saccadic velocity affected kinematic measures. These results support both a strong view of visual stream separation in the on-line control of action and richer spatial coding by unconscious processes than has previously been acknowledged.     

文化的考量:积极心理学当下之困与未来

积极心理学正在经历着从闲庭信步到临渊而立的转向。这种转向,既凸显了主流心理学面临着来自以积极心理学为代表的新兴势力的挑战与压力,同时,也表明积极心理学自身暴露出的短板与局限,以及由此向文化寻求支持的一种诉求,更是为寻求破局而作出的努力。可以预见,积极心理学将会以脑认知革命到来为契机,不断理顺积极心理、脑和文化环境三者关系,实现对心理学范式变革的显著的引领作用。     

积极怀旧情绪对疼痛共情影响的ERP研究

采用ERP技术比较积极怀旧情绪诱发组被试和中性情绪组被试在判断疼痛/非疼痛图片刺激时的疼痛共情反应,探讨积极怀旧情绪对个体疼痛共情加工的影响及其电生理学机制。结果发现,在P2成分和晚期的P3成分上,积极怀旧情绪下的疼痛图片比中性情绪下的疼痛图片诱发了更大的波幅。疼痛图片比非疼痛图片诱发更大的P2、N2、P3及400～600 ms正成分的波幅。结果表明积极怀旧情绪的诱发促进个体对疼痛刺激的加工和共情。     

科学划界视域下心理学学科焦虑与学科自觉

心理学科学划界是心理学发展史上的根本问题,构成了心理学发展历史研究的出发点和逻辑起点。心理学科学划界观点多样,争论不休,导致心理学处于学科焦虑当中。当前,心理学需要以文化文思促进学科自觉,这其中隐含的不仅仅是对心理学科学化追求道路的深入思考,同时,也是实现心理学话语方式转换以及与科学关系的深刻把握。
