未意识到错误影响错误后调整的电生理证据

Subjects: Psychology >> Cognitive Psychology

现有研究一致认为意识到错误可引起错误后调整,但是未意识到错误能否促使个体进行错误后调整尚存争议。本实验采用基于go/no-go范式的错误意识任务考察上述问题,并根据被试对自己按键反应正误主观报告将no-go错误反应分为意识到错误和未意识到错误。行为结果发现,意识到错误和未意识到错误后正确率均显著高于正确击中试次(正确go试次)后正确率;但是,意识到错误后试次反应时显著快于正确击中后反应时,未意识到错误后反应时显著慢于正确击中后反应时。该结果表明两类错误均优化了错误后行为表现,但是意识到错误后被试调整速度加快,未意识到错误后被试调整速度减慢。进而,时频分析发现意识到错误相较于未意识到错误诱发显著更强的alpha波能量。并且,前者在错误意识主观报告前已诱发alpha波,后者在错误意识主观报告反应后诱发alpha波。该结果表明意识到错误一直处于持续的注意监控中,而未意识到错误是任务引起的暂时注意控制。因此,本实验说明错误意识影响错误后调整,意识到错误可能采用类似主动性控制的策略调节错误后行为,而未意识到错误可能采用类似反应性控制的策略调节错误后行为。

正念对亲密关系的影响

Subjects: Psychology >> Social Psychology

亲密关系中的正念,是指个体有意识地关注可能影响关系的感觉或想法。由于其有助于提高关系满意度并缓解关系冲突,因而逐渐在理论和应用上受到关注。二元互动过程理论有助于在二元框架下理解正念影响亲密关系的过程和结果,研究者通常采用测量法、实验诱导法和正念干预探究正念对亲密关系的影响。鉴于正念干预对亲密关系具有防护和补救功能,因此被应用于相对幸福、面临挑战和陷入危机等不同关系状态。未来的研究可根据关系的阶段特征和可能的反向作用建构理论;根据亲密关系的二元互动和阶段特点,从多维、动态发展的视角界定概念,通过互评法和观察编码法进行测量;采用更严谨的设计明确干预效果;并且关注潜在的消极影响。

Neuroanatomical correlates of individual differences in self-awareness of highly practiced visuomotor skills

Metacognition refers to the ability to introspect our cognitive ability, which plays an essential role in guiding and optimizing our activities. However, little is known about metacognitive capacity for highly practiced motor behaviors and its neural correlates. Using structural and functional magnetic resonance imaging (MRI), the present study examined the brain substrates underlying individual differences in self-awareness of handwriting in adults, a highly practiced visuomotor skill. Results showed that adult writers generally overestimate their handwriting skill, which is more pronounced in males relative to females. The extent of overestimation of handwriting quality was positively correlated with grey matter volume in the left fusiform gyrus, right middle frontal gyrus and right precuneus. Moreover, the activation of these regions in a handwriting task was not correlation with self-awareness of handwriting, confirming that the identified connection between brain structures and handwriting self-awareness is independent of task performances. The left fusiform gyrus and right middle frontal gyrus are thought to represent domain-specific brain mechanisms for handwriting self-awareness, while the right precuneus is likely to be a domain-general brain mechanism, suggesting that the ability of introspect practiced visuomotor skills relies on both domain-general and domain-specific brain systems. Together, this study is the first to reveal the neuroanatomical correlates of a highly practiced motor behavior, extending our understanding about the neural basis of human metacognition.

Subjects: Psychology >> History of Psychology

本文从资源的视角,在团队和个体两个层面探究了跨界行为分别对团队创造力和个体创造力的影响以及中介机制和边界条件。采用多阶段-多来源的方式收集数据。研究结果表明在团队层面上,团队跨界行为会提高团队创造力,但在个体层面上,员工跨界行为通过增加员工的角色压力对个体创造力产生不利影响。角色宽度自我效能感调节了上述关系,相比于角色宽度自我效能感较高的员工,角色宽度自我效能感较低的员工实施了跨界行为后更容易产生角色压力,对个体创造力的负向影响更强
