Outerdirectedness has been found in nonretarded and institutionalized retarded children to be related inversely to cognitive level and directly to history of failure experiences. The developmental nature of outerdirectedness was investigated among noninstitutionalized EMR children using two independent measures of outerdirectedness. Forty subjects, comprising two MA levels, were given a block-design task that was equally difficult for both MA groups. Glancing from the task was found to be related inversely to MA. On a task in which subjects were scored for the amount of imitation of the experimenter's behavior, imitation was also found to be related inversely to MA. However, imitation and glancing were not correlated, suggesting that they may tap different aspects of outerdirectedness.
在非智力迟钝及收容机构中的智力迟钝儿童身上发现,外向性与认知水平呈负相关,与失败经历史呈正相关。使用两种独立的外向性测量方法,对非收容机构中的可教育智力落后(EMR)儿童的外向性发展本质进行了研究。四十名研究对象,分为两个心理年龄(MA)水平组,他们被给予了一项对两个MA组难度相同的积木设计任务。结果发现,从任务上移开视线的行为与MA呈负相关。在一项根据模仿实验者行为的程度对研究对象进行评分的任务中,也发现模仿行为与MA呈负相关。然而,模仿和移开视线这两种行为并无相关性,这表明它们可能反映了外向性的不同方面。
