ATTITUDES AND SOCIAL COGNITION Clever Hands: Uncontrolled Intelligence in Facilitated Communication

Five studies examined how people who are answering questions on behalf of another person may use their own knowledge to answer correctly while attributing authorship of their answers to the other. Experiments 1 and 2 found that participants instructed to answer yes/no questions randomly were unable to do so. They were more often correct on easy than hard questions, and extended opportunity and incentive did not reduce this effect. Experiments 3–5 found similar correctness for participants who were asked to answer yes/no questions by sensing either the ostensible keyboard finger movements or unvoiced inclinations of another person who had been admonished not to answer, and who was in fact a confederate and was not even given the questions. In this paradigm, the answers were often attributed to the other.
