Early experience likely plays an important role in the development of the ability to discriminate facial expressions of emotion. We posited that compared to children reared with their biological families (n=72), abandoned children being reared in institutions (n=39) should demonstrate impairments in this ability. The visual paired comparison procedure was utilized to assess the abilities of 13- to 30-month-old children to discriminate among multiple pairs of photographs of facial expressions. Both groups exhibited a normative profile of discrimination, with no group differences evident. Such findings suggest that early institutionalization does not affect the ability of 1- to 3-year-olds to discriminate facial expressions of emotion, at least as inferred by the Visual Paired Comparison Procedure.
早期经历可能在辨别面部表情情感能力的发展中发挥重要作用。我们假设,与在亲生家庭中抚养长大的儿童(n = 72)相比,在机构中抚养的弃儿(n = 39)在这种能力上应表现出缺陷。采用视觉配对比较程序来评估13至30个月大儿童辨别多对面部表情照片的能力。两组均表现出正常的辨别能力,没有明显的组间差异。这些发现表明,至少从视觉配对比较程序推断,早期进入机构抚养并不会影响1至3岁儿童辨别面部表情情感的能力。
