The Association Between Maternal Control and Sense of Coherence in Chinese Adolescents: Self-Efficacy as a Mediator and Stressful Life Events as a Moderator

Journal of Happiness Studies - Both parental support and overprotection have been found to be associated with adolescents’ sense of coherence (SOC) in prior studies. It is unclear, however,...

转换概率和词长期待对语音统计学习的影响

语音统计学习指个体在加工人工语言过程中, 可以追踪音节间的转换概率实现切分语流、提取词(语)的过程。本研究采用2(转换概率：高转换概率、低转换概率) × 2(词长期待：两音节、三音节)的混合实验设计来考察转换概率和词长期待对语音统计学习的影响, 转换概率是被试间变量, 词长期待是被试内变量。事后检验发现, 仅在低转换概率人工语言的三音节迫选条件下, 被试没有表现出显著的学习效果。事先对比发现, 在学习低转换概率的人工语言后, 被试完成三音节迫选试次的成绩显著低于两音节迫选试次; 在三音节迫选试次中, 学习低转换概率人工语言被试的成绩也显著低于学习高转换概率被试的成绩。以上结果说明, 转换概率和词长期待共同影响个体语音统计学习的效果。     

动态性对简笔画动物审美的影响及其神经机制

运用行为和fMRI技术, 通过比较动态刺激与静态刺激审美判断的行为和脑机制的异同探讨动态性对简笔画动物审美的影响, 包括两个实验。结果发现, 动态简笔画动物的美观程度评分和喜欢程度评分都显著高于静态简笔画动物。同时, 动态简笔画动物审美判断激活的区域基本涵盖了静态简笔画动物审美所激活的区域, 二者都激活了枕叶区等视觉加工区域、额叶区等认知加工区域、眶额叶皮层等奖赏区域以及海马、脑岛、扣带回、杏仁核等情绪加工区域。与静态简笔画动物的审美相比, 动态简笔画动物的审美显著激活了双侧舌回、双侧MT。本研究结果表明, 动态性影响了对简笔画动物的审美, 动态简笔画动物比静态简笔画动物被判断为更加美观。     

Lay theories and ageist attitudes at work: Essentialist beliefs about cognitive aging,fixed mindsets,and cyclical perception of time are linked to ageist attitudes toward older workers

To resolve the problem of ageist attitudes in organizational contexts, the psychological processes that contribute to their endorsement must be investigated. We suggest that lay theories of aging (essentialist beliefs about cognitive aging, EBCA), fixed versus growth mindsets, and lay theories of time (LTT, perceptions of time as change versus. repetition) represent a set of beliefs linked to ageist attitudes toward older workers. We also propose that relationships between these beliefs and ageism are mediated by stereotypical perceptions of older workers. In a pilot study, we constructed a measure of ageist attitudes toward older workers (AATOW). In the main study, we surveyed 166 younger workers (18–30 years old, employed full-time), measuring EBCA, mindsets, LTT, age-related stereotypes, and AATOW. The results demonstrated that there were significant relationships between EBCA, fixed mindset, LTT, and ageist attitudes. The relationships between EBCA and ageism, and mindsets and ageism were mediated by perceptions of older workers as not adaptable, while the relationship between LTT and ageism was not mediated by age-related stereotypes. Implications for organizational efforts to nurture an age-inclusive intergenerational workforce are discussed.     

特质正念对初中生学业情绪预测偏差的影响

基于真实考试和实验室模拟情境, 考察特质正念对初中生学业情绪预测偏差的影响及其机制。结果表明：(1)学业领域存在情绪预测偏差; (2)特质正念影响情绪预测偏差, 特质正念水平高的初中生情绪预测偏差相对更小, 反之则更大; (3)注意聚焦在特质正念影响情绪预测偏差中存在中介作用。本研究初步提出正念的“扩大-联结”解释模型, 推进了学业领域情绪预测的研究, 具有良好的生态学效度和切实的教育实践价值。     

神经重用假说的汉语情绪词汇加工证据

神经重用假说认为对词的情绪效应可以不经语义形成而先行产生, 这更有助于人类适应环境。为了检验这一假说, 设计脑电实验和行为实验, 记录被试加工汉语厌恶情绪词和中性词的特征。结果发现, 170 ms左右厌恶词与中性词的ERPs发生分离, 且在枕部出现情绪刺激视觉注意关联的EPN; 厌恶词与中性词N400差异波溯源定位于脑岛附近, 其最大激活点时间窗口开始于380 ms。这表明在情绪词汇的语义分析之前就出现了情绪效应, 结果支持了神经重用假说。     

新颖语义联结在顿悟促进记忆效果中的作用

采用成语谜题选择任务, 通过学习-测验范式探究顿悟促进记忆的认知神经机制。实验1采用行为实验, 验证成语谜题选择范式在探究顿悟促进记忆中的有效性, 结果显示, 相比于寻常联结条件, 新颖联结条件下被试在学习阶段具有更高的顿悟感得分, 在测试阶段具有更高的正确率, 范式的有效性得以验证。实验2采用fMRI技术探究顿悟促进记忆的关键脑区。结果显示, 相比于失败记忆新颖联结条件, 成功记忆新颖联结条件更强地激活了顿悟过程相关脑区, 包括海马、杏仁核、额中回、颞上回和颞中回。这说明在学习阶段的顿悟问题解决过程中, 对信息的深加工与积极情绪促进了随后的记忆; 对其进一步分析发现, 相比于寻常联结记忆, 新颖联结对记忆的促进效应主要与右侧海马激活有关, 它可能反映了在顿悟问题解决中新颖联结形成过程建立了情节记忆以及新颖且有价值的语义联结。研究结果表明新颖语义联结形成在顿悟促进记忆中发挥了重要作用。     

汉语高功能自闭症儿童代词加工:利用提及顺序和重读线索的表现

采用句子理解任务分别探究了5~7岁的汉语高功能自闭症儿童在单独提及顺序线索,提及顺序线索和重读线索共现两种条件下代词加工的表现。研究结果表明,汉语高功能自闭症儿童不像智商和工作记忆广度匹配的同龄典型发展儿童一样能够单独利用提及顺序线索加工代词,即倾向于选择首先提及的实体作为代词的指称对象,而表现为随机选择代词所指。当提及顺序线索和重读线索共现时,典型发展儿童在两条线索一致和冲突时都倾向于依靠重读线索加工代词,而汉语高功能自闭症儿童对两条线索都不敏感,表现为随机选择代词所指。这表明5~7岁的汉语高功能儿童不能够利用这两条线索加工代词,在利用语篇突显性线索加工代词方面存在困难。
