Infants infer intentions from prosody

Two studies were conducted to examine infants' ability to discern intentions from lexical and prosodic cues. Two groups of 14-18-month-olds participated in these studies. In both studies, infants watched an adult perform a sequence of two-step actions on novel toys that produced an end-result. In the first study actions were marked intentionally with both lexical and prosodic cues. In the second study, the lexical markers of intention were presented in Greek, thus providing infants with prosodic but not lexical cues. In both studies, infants reproduced more intentional than accidental actions, suggesting that infants can infer intentions from prosodic cues. (C) 2011 Elsevier Inc. All rights reserved.
