本文探讨了一组感知的可变性的替代措施。测量之间的相关性的模式表明，变异性可以从两个方面来考虑：从群体集中趋势的群体成员的感知分散度，以及该群体被视为符合群体刻板印象的程度。外组同质性的证据是存在的两种类型的变异性判断，使用男性和女性作为目标群体。判断组的变异性没有预测的方差检索组成员围绕自己的平均值。在组内的情况下，变异性的判断预测的差异检索组成员从组的平均值。同样，组内（而非组外）的变异性也可以通过自我与组平均值的差异来预测。第二项研究使用有声谈话协议显示，当一个人对内组做出变异性判断时，自我和亚组更有可能被讨论。组内几乎从未讨论过组内和组外讨论。模型的群体变异性判断的结果的影响进行了讨论。
This article examines alternative measures of perceived variability of a group. The pattern of correlations among the measures suggests that variability can be thought of in 2 ways: the perceived dispersion of group members from the group central tendency and the extent to which the group is seen as fitting the group stereotype. Evidence of out-group homogeneity was present for both types of variability judgments, using men and women as the target groups. Judgments of group variability were not predicted by the variance of a retrieved set of group members around their own mean. In the case of the in-group, judgments of variability were predicted by the discrepancy of the retrieved set of group members from the group mean. Likewise, in-group, but not out-group, variability was also predicted by discrepancy of self from the group mean. A 2nd study using talk-aloud protocols revealed that the self and subgroups were more likely to be discussed when one was making variability judgments about the in-group than about the out-group. Instances of the group were almost never discussed for the in-group and were discussed for the out-group. Implications of the results for models of group variability judgments are discussed.
