One hypothesis to explain perceptual narrowing in speech perception is the distributional learning account. This account claims that both infants and adults are able to infer the number of phonemic categories through observations of frequency distributions of individual phones in their speech input (Maye, Werker, & Gerken, 2002). Although the…

Over their 1st year of life, infants' "universal" perception of the sounds of language narrows to encompass only those contrasts made in their native language (J. F. Werker & R. C. Tees, 1984). This research tested 40 infants in an eyetracking paradigm and showed that this pattern also holds for infants exposed to seen language--American Sign…

This study is an investigation of 2-month-old infants' abilities to visually localize visual and auditory peripheral stimuli. Each subject (N=40) was presented with 50 trials; 25 of these visual and 25 auditory. The infant was placed in a semi-upright infant seat positioned 122 cm from the center speaker of an arc formed by five loudspeakers. At…

In an attempt to address the issue of bimodal coordination of featural stimuli, the sensitivity of 3-month-old infants to the auditory and visual components of male and female stimulus configurations was examined. Measures were made of the infants' visual attention to a male or female face while they listened to a male voice, female voice, or to…

This monograph is a collection of papers describing a series of loosely related studies of visual attention, auditory stimulation, and language discrimination in young infants. Titles include: (1) Infant Attention and Discrimination: Methodological and Substantive Issues; (2) The Addition of Auditory Stimulation (Music) and an Interspersed…
