External source monitoring in a real-life event: Developmental changes in ability to identify source persons

Abstract

The present study investigated young children's and adults' external source-monitoring abilities with respect to facial identification accuracy for complex live events. Five- to 6-year-olds and adults watched a magic show in which three different female magicians (i.e. source persons) performed three different kinds of magic tricks each. After approximately 1 month, the participants were asked to recognize what kinds of magic tricks had been performed, to make face identifications as to which magician had performed those magic tricks and to recognize those magicians' attributes. Results showed that both young children and adults had more difficulty with identifying source persons than recognizing them in a real-life event in which a number of persons appeared. Especially for young children, low credibility was shown not only for the source memories but also for the recognition memories of the source person attributes.
