【摘要】：探讨了表情因素作为身份特征对多身份追踪中分组效应的影响。采用多身份追踪范式,8个客体为表情图片(正性、负性、中性)其中4个为目标,对45名被试进行了有无眉毛线索对追踪表现影响的测查。实验条件分别为:目标表情与非目标表情完全不相同组(4水平,简称分组)、目标表情与非目标表情都由两种相同数量的表情混合组成(3水平,简称配对)与基线组(8个客体表情相同)。发现分组水平的成绩显著优于基线组,配对水平的成绩显著低于基线组,并表现出了负性表情的追踪优势;另外,有无眉毛线索对追踪表现无显著影响。这一结果说明多身份追踪中存在基于表情特征的分组效应,负性表情的分组知觉高于正性表情。
[Abstract]:The effects of facial expression factors as identity features on grouping effect in multiple identity tracking are discussed. In the multi-identity tracking paradigm, four of the 8 objects were used as the target, and 45 subjects were tested for the influence of eyebrow cues on the tracking performance. The experimental conditions were as follows: the target expression was completely different from the non-target expression group (group 4), and the target expression and the non-target expression were composed of two kinds of facial expressions of the same number. The pairing was similar to the baseline group (8 object expressions). It was found that the score of group level was significantly better than that of baseline group, and the score of matched group was significantly lower than that of baseline group, and showed the advantage of negative expression tracking, in addition, there was no significant effect of eyebrow cues on tracking performance. The results show that there is a grouping effect based on facial expression feature in multi-identity tracking, and the group perception of negative expression is higher than that of positive expression.
