Salience of handedness in the spontaneous self-concept

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.
