Summary

Accommodation

Students were tested under one of three conditions: (1) token reinforcement contingent on each correct response with the provision of back-up reinforcers (reinforcement condition), (2) token reinforcement contingent on correct responses without the provision of back-up reinforcers (feedback condition), and (3) standard conditions.

Participants

Participants included 30 preschool children (20 boys and 10 girls) ages 3 to 3 1/2, from lower socio-economic families in a small rural town in Ontario (Canada).

Dependent Variable

Performance on the Wechsler Preschool and Primary Scale of Intelligence (WPSSI), including Verbal, Performance, and Full-Scale scores, was used as the dependent variable. Students were also pre-tested using this test. Average pretest to retest interval was 16.3 days.

Findings

Feedback did not increase the number of correct responses. Tangible reinforcement did result in a marked, general increase in IQ scores. The reinforcement condition also resulted in more positive student attitudes toward the test.
