Effects of reinforcement on standardized test performance.

The effects of two different motivational conditions upon standardized test performance were explored for two student populations. The first study involving 12 trainable retardates showed a significant increase in score on the Metropolitan Readiness Test given under reinforcement conditions when these results were compared with scores taken under standard testing conditions. In a second study, these same results were obtained with a group of 30 normal fourth-graders. An additional study was conducted to determine the effect of different experiences with token reinforcement procedures on test performance. It was found that a group of children with six weeks' exposure to reinforcement for daily academic performance scored higher under both conditions of test administration (standard and reinforcement) than a control group. However, in a single exposure to token reinforcement for correct performance on the Metropolitan Test, both the experimental group and its match control showed a parallel increase in test performance. These findings offer a procedure that yields a more representative assessment of a student's academic achievement than does testing under standard conditions.
