遮挡范式下对碰撞时间的估计

本文研究视觉信息对碰撞时间估计的影响。实验采用遮挡范式（ｏｃｃｌｕｓｉｏｎ ｐａｒａｄｉｇｍ）,遮挡一段固定的距离,让被试估计该段距离所用的时间。自变量为移动速度与挡板的宽度。过程：让被试看速度知觉仪上移动的红灯,估计碰撞发生时按下电键。结果表明,移动速度对时间估计的准确性影响显著,速度越大,估计准确性越高;移动速度还与挡板宽度存在交互作用,即速度快、挡板宽度时碰撞时间的估计更准确,而速度慢、挡板     

FOK:是线索熟悉,还是目标提取?

以围棋定式为实验材料,检验了关于FOK判断的线索熟悉假说和目标提取假说。结果表明：在有线索可以利用的情况下,被试会依据线索的熟悉作出FOK判断;而在线索难以利用的情况下,被试就会依据目标的提取来作出FOK判断。该文还对FOK的研究方法提出了一点看法。     

Divine reconciliations: The Mother of Grain and Gautama Buddha in De'ang religion

Located in China along the boarders of China and several Southeast Asian countries, Southwestern China is characterised by ethnic diversity and the influence of various world religions, especially that of different schools of Buddhism. This article examines how the De'ang people transform the cosmological order of Theravada Buddhism to reassert the indispensable position of their indigenous agricultural goddess, the Mother of Grain. Corresponding to myths that portray the reconciliation between the goddess and Gautama Buddha, the rituals dedicated to her are performed primarily by women, while male monastic institutions participate on certain ceremonial occasions. A comparison with similar beliefs and rituals in other cultural groups in the region demonstrates that the Mother of Grain in De'ang religion offers an exceptionally strong local challenge to the male bias embedded in Buddhism. By examining the conflicts and compromises between Buddhism and the indigenous religions of Southwest China, this article analyses the complex local negotiations of gender ideologies when world religions and local beliefs are at odds.     

Parental Dysphoria and Children’s Adjustment: Marital Conflict Styles,Children’s Emotional Security,and Parenting as Mediators of Risk

Dimensions of martial conflict, children's emotional security regarding interparental conflict, and parenting style were examined as mediators between parental dysphoria and child adjustment. A community sample of 262 children, ages 8–16, participated with their parents. Behavioral observations were made of parents’ interactions during marital conflict resolution tasks, which children later observed to assess their emotional security. Questionnaires assessed parents’ dysphoria, parenting, and children's adjustment. Structural equation modeling indicated that parental dysphoria was linked with child adjustment through specific and distinct mediating family processes, including marital conflict and parenting. Children's emotional security in the context of particular marital conflict styles also mediated relations between parental dysphoria and child adjustment problems, with similar pathways found for mothers and fathers. These pathways remained significant even after significant parenting contributions were considered.     

高中生自我调节学习与自尊:感知教师支持及性别的调节作用

采用自我调节学习问卷、感知教师支持问卷及自尊问卷,对334名高中生进行测量,探究感知教师支持及性别在自我调节学习与自尊之间的调节作用。结果表明:(1)自我调节学习与自尊呈显著正相关,感知教师支持与自尊及自我调节学习呈显著正相关;(2)感知教师支持及性别在自我调节学习与自尊之间均起调节作用:自我调节学习对自尊的影响在女生中更为明显,感知高水平的教师支持缓解了低自我调节学习对自尊的负面影响。     

睡眠限制对认知功能的影响及其潜在作用机制

睡眠限制已然成为现代社会人们普遍面临的问题, 其对个体身心机能的影响备受研究者关注。众多研究表明, 睡眠限制会对注意功能、执行功能和长时记忆等不同认知领域的心理加工产生差异化影响, 且影响程度与任务类型、睡眠限制的严重程度、年龄和性别等因素相关。研究者们提出了4种主要的作用假说：唤醒假说、注意控制假说、警觉性假说以及前额皮层易感性假说。未来研究需要从关注个体间差异、使用动脉自旋标记灌注功能磁共振成像技术以及重视轻度睡眠限制的影响等角度进行深化和扩展。     

食物线索注意偏向及其神经机制

与其他类型的刺激相比, 个体会优先注意食物相关刺激, 即对食物刺激的注意偏向。对影响食物线索注意偏向个体因素研究的分析发现：(1)在状态因素中, 饥饿以及与自我威胁有关的、唤起强度大的负性情绪对食物线索注意偏向有增强作用, 这在注意加工的早期和晚期都有体现; (2)在特质因素中, 行为研究发现, 相比于体重正常个体和非限制性饮食者, 超重/肥胖个体以及唤起节食目标的成功限制性饮食者没有更强的注意偏向, 但是, ERP研究发现, 在注意加工的早期阶段, 就出现了特质因素对食物线索注意偏向的影响; (3) fMRI研究发现, 对食物线索的注意过程伴随着脑岛、眶额叶皮层等与奖励相关的脑区及视觉注意网络的激活。未来研究需要：(1)从动态角度研究注意偏向, 进一步提高测量的信度; (2)使用专门的范式探究个体因素影响注意偏向的神经机制; (3)严格分离不同状态因素; (4)对被试进行严谨筛选和划分, 做好被试间的对比研究。     

情绪词类型效应：区分情绪标签词和情绪负载词的行为和神经活动证据

情绪标签词直接表达情绪状态,而情绪负载词本身不表达情绪状态,但能引发个体的情绪反应。通过对情绪标签词和情绪负载词的相关研究综述发现,情绪标签词与情绪负载词的加工优势存在不一致的结果;任务需求、语言类型和词汇特征是导致情绪词类型效应不一致的主要原因;情绪标签词与情绪负载词的加工差异可以通过语义表征的具身假说、密度假说进行解释。未来研究应深入考察情绪标签词与情绪负载词加工差异的原因;考察两种词在句子和语篇水平的加工差异;提供能够直接解释情绪词类型效应的理论假说;对比中英双语者加工中文和英文情绪标签词和情绪负载词的差异;采用神经成像技术继续探查情绪信息与语义信息加工的神经机制。     

大学生对临终者的内隐与外显态度

目的:考查大学生对临终污名者的内隐、外显态度。方法:使用内隐联想测验(IAT)和相应的外显测验,对安徽师大在校本科生、研究生共60名进行实验研究。结果:大学生在临终者内隐态度上,不相容任务反应时(1185.53±278.95)ms长于相容任务反应时(765.62±199.10)ms;大学生对临终者外显态度均表现出消极态度,但对于临终关怀的态度表现出积极(1.54±0.52);被试的性别以及被试是否接触过临终者并不能改变内隐以及外显态度。结论:大学生对临终者具有负面刻板印象以及污名效应,临终关怀以及对临终者的偏见应该引起重视。
