The distinctiveness postulate regarding selective perception implies that an aspect of a complex stimulus is likely to be noticed in direct proportion to its distinctiveness in the environment in which it is perceived. An implied prediction tested in the present study is that handedness is more salient in the self-concepts of left-handers than of right-handers. The spontaneous self-concept was measured in two different populations by open-ended "Tell us about yourself" questions. In each group, a significantly greater proportion of left- than right-handers mentioned their handedness as part of their self-concept.
关于选择性知觉的独特性假设意味着,复杂刺激的一个方面在其被感知的环境中的独特程度与它被注意到的可能性成正比。本研究中测试的一个隐含预测是,左撇子的自我概念中,用手习惯比右撇子更为突出。通过开放式的“介绍一下你自己”问题,在两个不同群体中测量了自发的自我概念。在每个群体中,将用手习惯作为自我概念一部分提及的左撇子比例显著高于右撇子。
