Where exactly am I? Self-location judgements distribute between head and torso

I am clearly located where my body is located. But is there one particular place inside my body where I am? Recent results have provided apparently contradictory findings about this question. Here, we addressed this issue using a more direct approach than has been used in previous studies. Using a simple pointing task, we asked participants to point directly at themselves, either by manual manipulation of the pointer whilst blindfolded or by visually discerning when the pointer was in the correct position. Self-location judgements in haptic and visual modalities were highly similar, and were clearly modulated by the starting location of the pointer. Participants most frequently chose to point to one of two likely regions, the upper face or the upper torso, according to which they reached first. These results suggest that while the experienced self is not spread out homogeneously across the entire body, nor is it localised in any single point. Rather, two distinct regions, the upper face and upper torso, appear to be judged as where “I” am.     

社会距离与合作指数对不同年龄青少年合作行为影响的差异

本研究采用重复囚徒困境实验范式,考察了社会距离和合作指数对不同年龄青少年（初中生、高中生和大学生,且每个年龄段的被试数为40名）在博弈决策中的合作行为的影响。结果发现：（1）随着年龄的增加,青少年合作行为的总体趋势表现为下降;（2）社会距离对大学生的合作行为的正向作用显著,而中学生的合作行为却不受其影响;（3）个体合作率会受到合作指数的促进作用,但这种促进作用在大学生中表现的更为显著。即随年龄增长,个体会更少的采取合作行为,并且个体是否采取合作在更大程度上基于当前博弈中的收支情况和与博弈对象之间的社会距离。     

被信任者社会身份复杂性对其可信性的影响

被信任者社会身份是单一的还是多样的, 这种数量差异可以体现其社会身份的复杂性。本研究探讨了被信任者社会身份复杂性(单一身份、多重身份)如何影响人们对其可信性的评价。实验1考察了被信任者社会身份复杂性对其可信性的影响以及社会距离在其中的中介作用。实验2用于检验被信任者所属群体类型(内群体、外群体)是否调节他们的社会身份复杂性对其可信性的影响。研究结果表明：被信任者多重社会身份的凸显会提高人们对其可信性的评价, 社会距离在二者之间起着完全中介作用; 群体类型对社会身份复杂性的影响具有调节作用, 社会距离的中介作用在对外群体成员的可信性评价中更为明显。
