The present study examines the relation between children's theory of mind abilities and their tendency to assent to fictitious events when questioned repeatedly across interviews. Children between the ages of 3 and 6 years were interviewed individually either four or seven times about a fictitious and a real staged event, and in addition given a false belief test as well as a fantasy-reality distinction test. Children's performance on the false belief task addressing the understanding of their own false belief was a better predictor for assents to false events than was understanding the false belief of another person, age, number of interviews and performance on a fantasy-reality distinction task. Children's memory for a staged event showed that repeated questions across interviews was related to a decrease in correct assents to having experienced a staged event, an increase in wrong yes-responses about touch and erroneously mentioning names of children who had not been present during the staged event.
