10 Rett综合征（RS）的女孩和10个控制女孩执行的注意力任务中，一个复杂的刺激，然后由个人的刺激与干扰。受试者必须区分先前呈现的刺激和干扰物。斯普斯卡共和国女孩在有定型观念约束和无约束的条件下完成这项任务。由于患者无法区分约1/3的个体刺激，RS发生了过度选择性。在这两种情况下，正确回答的数量没有统计学差异;当刻板印象得到遏制时，RS女孩学得很快，而当刻板印象缺乏遏制时，则相反。(C)2008爱思唯尔有限公司保留所有权利。
Ten Rett syndrome (RS) girls and 10 control girls executed an attentional task in which a complex stimulus was shown followed by individual stimuli presented with distractors. Participants had to discriminate previously presented stimuli from distractors. RS girls carried out the task both in a condition with the containment of stereotypies and in a no-containment condition. Overselectivity occurred in RS since patients failed to discriminate about 1/3 of the individual stimuli. There were no statistical differences with respect to the number of correct responses in the two conditions; RS girls learned quickly when their stereotypies were contained as opposed to when the containment of stereotypies was lacking.
