Each subject described a person he knew well by responding to items adapted from Jackson's Personality Research Form. He then indicated whether, in responding, he had felt uncertain of his response, had found the item ambiguous or difficult to apply, etc. The closeness of each item to each described person was computed in terms of the Rasch model. Correlations between closeness and presence of each inappropriate response component were computed for each subject on each of two scales. Most of the proportions of positive correlations were significant, as in previous studies of closeness and inappropriate response processes in self-descriptions, suggesting that similar processes are involved in describing self and others.LITTLE is known about the processes that occur in persons when they are describing others. This study investigated these processes during subjects' descriptions of others in terms of responses to dichotomous-choice items from an instrument originally developed to measure personality traits of respondents. The primary objective was to determine whether these processes would be like those observed in responding to self-report instruments. Kuncel (1973) and Kuncel and Fiske (1974) have identified inappropriate components in response processes during self-descriptions and have found the occurrence of these components to be related to the relative proximity of the item and subject points on an underlying trait continuum.
