The dynamics of intermodal matching: Seven- and 12-month-olds' intermodal matching of affect

摘要

The purpose of this experiment was to examine whether and how a common methodological difference frequently employed within the intermodal matching procedure affects infants' intermodal matching. Specifically we examined the effects of incorporating or excluding silent control trials on seven- and 12-month-olds' intermodal matching of affect. Results revealed that seven-month-olds showed reliable matching when presented all in-sound trials whereas 12-month-olds showed reliable matching when half of the trials were presented silently and half of the trials were presented in-sound. Results are discussed in terms of the dynamics of infant attention and those conditions where the inclusion of silent trials may be appropriate.
