Human Judgements of Control: The Interaction of the Current Contingency and Previous Controllability

Two experiments were carried out to determine the effects of the learned helplessness treatment on judgement of control over a outcome. In the first experiment judgements were found to be sensitive to the actual level of response-outcome contingency. When the contingency level was high, this sensitivity was also influenced by pretreatment, in that a prior uncontrollable experience gave rise to lower judgements than both a controllable one and no experience at all. The latter pretreatments produced the most accurate judgements. In the second experiment the judgements after an uncontrollable task were found to be insensitive to a previous controllable or uncontrollable pretreatment. The results are discussed in terms of contingency-learning models.
