Abstract: 

Thirty-two subjects completed 2 stimulus equivalence tasks using a matching-to-sampie paradigm. One task involved direct reinforcement of conditional discriminations designed to produce derived relations between self-referring stimuli (e.g., me, myself, I) and positive evaluation words (e.g., whole, desirable, perfect). The other task was designed to produce derived relations between selfreferring stimuli and negative evaluation words (e.g., unworthy, flawed, inadequate). Performance on each task was recorded via response latency and percent correct. Prior to completion of the equivalence tasks, subjects completed 2 self-report measures: the Outcome Questionnaire-45 (OQ-45) and the Rosenberg Self-Esteem Scale (RSE). Subjects were divided into groups based on their OQ-45 score (high or low distress) and RSE score (high or low self-esteem). Significant differences in percent correct were found between both the 00-45 groups and the RSE groups. Subjects who reported high distress and a negative sense of self made significantly more errors on the tests for equivalence for the task that required matching self-referential stimuli with positive evaluation words.
