Jung's Psychological Types: Meaning and Consistency of the Questionnaire

Third-grade children (n = 72) completed arithmetic problems in an individually conducted experimental session while receiving one of three types of verbal feedback (positive statements, negative statements, or their combination), either randomly or contingent on the accuracy of their answers. Random feedback produced a higher rate of responding than did contingent feedback with no loss of accuracy. The varying types of verbal feedback statements did not produce differential effects on either rate or accuracy measures. These results were discussed in terms of the ineffectiveness of verbal feedback in producing differential results with tasks not involving new learning and in terms of mechanisms which could account for the efficacy of random feedback.
