Children's Attention to Others' Beliefs during Persuasion: Improvised and Selected Arguments to Puppets and People

Until now children's attention to the beliefs of people they wish to persuade has been examined experimentally via tasks that were artificial in important respects. To determine whether such research has underestimated children's psychological perspective taking, two studies that manipulated task elements pertinent to ecological validity were conducted. Children in three age groups (3, 4/5, and 6/7 years) were asked (forced-choice and open-ended formats) how best to persuade puppets and people, with differing beliefs, to pet and play with various toy animals. Children offered as many or more belief-relevant arguments in response to forced-choice as to open-ended questions. Only the oldest group attended to beliefs more when persuading a person compared with a puppet. Even on more realistic tasks, significant improvement with age across task formats confirmed a developmental trajectory in line with extant reports of children's belief reasoning. The findings support the idea that enhanced social competence corresponds specifically to children's increasing attention to beliefs in social interactions such as persuasion.
