title: Young children's appreciation of the mental impact of their communicative signals.
abstract: This work addresses whether 30-month-olds appreciate that their communicative signals are being understood (or not) by another person. Infants produce a range of behaviors, such as repairing their failed signals, that have been construed as evidence that they have an implicit theory of mind. Such behavior could be interpreted as attempts to obtain some desired goal rather than as attempts to gain listener understanding. This study was designed to separate listener comprehension from obtaining a material goal. In 4 conditions, children either did or did not get what they wanted and the experimenter understood or misunderstood their request. As predicted, children clarified their signal more when the experimenter misunderstood compared to when she understood. Regardless of whether young children achieved their overt goal, they engaged in behaviors to ensure their communicative act had been understood.
