Young children's persuasion tactics, and how these reflected attunement to others' mental states, were explored in archived longitudinal samples of transcribed at-home conversations of four children, three to five years old. Over 87,000 utterances were examined to identify conversation ‘chunks’ involving persuasion; 1,307 chunks were then coded for who initiated the persuasion, the persuader's goal, tactics employed, the presence of cues about others' beliefs and desires, and whether children attended to such information. Analyses suggested that persuasion exchanges were initiated similarly by children and adults, were stable in frequency and length across time, and involved a limited set of persuasion tactics. Children's attempts to change beliefs increased although explicit mental-state cues were only rarely available. When such cues were available, children more often than not altered their tactics. Implications for our understanding of children's developing social cognition and theory of mind, as well as the limitations of conversational analysis, are discussed. [ABSTRACT FROM AUTHOR]
