| summary | An important issue in the study of infants' processing of language is how best to gauge attention, encoding, and recognition of sound in listeners with limited behavioral competency. The study of auditor perception in infants is also made challenging by the fact that the assessment ofwhether and how an infant is listening to sound is not as easily operationalized as in other modalities (e.g., visual perception in which the assessment involves measuring where an infant is looking).
Although a variety of methods exist for this purpose, the predominant favorite in the field of infant research is to measure the duration of infants' fixations to a visual event, when hearing a concurrent sound is contingent on looking. Differences in looking times are then taken as measures of auditory preferences/discriminations. Because there is reason to believe that infants' processing of unimodal v. multimodal events is not equivalent, it is important to examine ways in which visual events impact infants' processing of concurrent auditory information. The purpose of this talk is twofold: (1) to present data on developmental changes in infants' attention (defined both behaviorally and psychophysiologically) to static and dynamic visual events, and (2) to examine how visual events may enlighten and obscure evidence for infants' discrimination and recognition of speech information. |
