Children's spontaneous correction of false beliefs in a conversation partner.

Preschool children were tested for their ability to vary the verbal information they offered regarding an object's location depending on whether the person searching for that object was likely to infer or misinfer its location. Older children (mean age: 5 years 3 months) offered information in a selective fashion: If the location of the hidden object could be readily inferred by their conversation partner, they indicated its location only when explicitly asked but if its location was likely to be misinferred, they often indicated that location prior to being explicitly asked. The response pattern of younger children (mean age: 3 years 6 months) was less conclusive. A relatively large number of younger children took matters "into their own hands" and immediately grasped for the concealed object, irrespective of whether its location could be readily inferred. However, the reactions of the remaining 3-year-olds suggest that even at this age children may be sensitive to the likely beliefs of their conversation partner. © 1999 The International Society for the Study of Behavioural Development
