Investigated the effect of individually contracted incentives on WISC‐R performance of elementary school children. Forty‐eight middle‐ and 48 low‐ SES children were assigned to three treatment conditions‐tangible rewards, social rewards, and control‐based on their performance on a revised Mediator‐Reinforcement Incomplete Blank. Prior to testing, each child was allowed to select the reward (s)he desired most. Results indicated a significant SES × treatment interaction effect, which showed that both individualized tangible and social rewards effectively raised IQ scores of low‐SES children and, consequently, reduced the difference in IQ scores between the two SES groups.
