The Relationship

This study investigated the relationship between belief in one's ability to control reinforcements and performance in a binary-choice probability-learning situation under varying conditions of risk. The probability-learning task required S repeatedly to predict whether a red or green bulb would light up next. Red was programmed to occur 75% of the time. The sequence was random and not contingent upon Ss' responses. Rotter's Internal-External scale was used to select Ss who generally believed reinforcements were affected by their own behavior (internals) to compare with individuals who believed that most reinforcements were beyond personal control (externals). The conditions of risk were no-payoff, win or lose, win or break even, lose or break even, and reverse (lose for a correct guess and break even for an incorrect one). Performance on the reverse condition differed from all others, with Ss selecting the objectively more frequent event significantly less often. The difference resulted from the behavior of male externals and female internals, who predicted the less frequent event to avoid loss of chips. This is discussed within the framework of social learning theory.

Probability Task

The purpose of this experiment was to determine the differential effects of instructions on a two-choice probability task. One set of instructions emphasized the number correct on each side. Another set of instructions emphasized neither of the above. The results indicated that differences in instructions did not lead to differences in subjective probability for the three groups. All groups tended toward matching behavior.
