模糊再认（FR）判断—元记忆领域的新方法

Ｈａｒｔ所开创的ＦＯＫ研究范式表明,在记忆的提取阶段由客体水平的回忆能引起元水平ＦＯＫ判断,但历来的研究都忽略了由再认也能引起一种元记忆判断,这就是“模糊再认判断”（即ＦＲ判断）．本文论述了ＦＲ判断的概念,特性和研究方法并加以实验验证．ＦＲ判断发生在记忆提取阶段,有着与ＦＯＫ判断同等重要的研究价值和相似的研究方法．ＦＲ研究范式给予元记忆研究以新的思想和方法．     

触觉长度总合:应用复合变异刺激的实验

本文报道被动触觉的长度总合实验。在应用单一的标准刺激的条件下,在前臂内侧进行了单一的和各种复合的变异刺激的比较实验,所得到的结果没有显著差异。这与主动触觉和应用复合的标准刺激的实验结果相一致,表明长度总合是触觉的一种普遍现象。本文讨论了策略在长度总合中的作用与对长度辨别阈限的意义。     

不同性别比和童年经济状况对未婚男性性态度的影响

基于进化心理学的生命史理论,通过两个实验探讨性别比和童年经济状况同男性性态度间的关系。实验1和实验2分别采用图片和文字材料启动被试的性别比感知,结果发现感知性别比和童年经济状况对未婚男性的"随意性行为"态度表现出显著的交互效应：童年家庭经济状况差的未婚男性在感知到周围女性数量相对充裕的情境下,其性开放态度会较感知到周围男性数量充裕时明显上升;童年家庭富裕的男性的性开放态度在不同感知性别比下保持相对稳定。     

Perceiving high social mindfulness during interpersonal interaction promotes cooperative behaviours

Social mindfulness refers to individual's respect and protection of others’ options in interpersonal interaction. The object‐choosing task is a traditional paradigm to assess social mindfulness. Individuals with high social mindfulness would choose the nonunique object so that others would have more options; on the contrary, individuals with low social mindfulness would choose the unique object, which limits others’ choices. No prior study has examined whether perceiving people with different levels of social mindfulness affects one's cooperation. Based on this background, two experiments were conducted to address this question. In both experiments, a confederate participant's (Player A's) social mindfulness was manipulated by setting the frequency that Player A chose the unique and the nonunique objects. Then, participants were asked to interact with Player A in the public goods game (Experiment 1) or in the centipede game (Experiment 2). Convergent results showed that compared to those interacting with a socially unmindful person, participants interacting with a person perceived as socially mindful contributed more resources in the public goods game and chose to pass on more rounds in the centipede game. These findings suggest that perception of others’ high social mindfulness enhances one's own cooperative behaviour.
