During the second year of life, infants develop a preference to attach novel labels to novel objects. This behavior is commonly known as "mutual exclusivity" (Markman, 1989). In an intermodal preferential looking experiment with 19.5- and 22.5-month-olds, stimulus repetition was critical for observing mutual exclusivity. On the first…

Presents nine experimental studies investigating auditory and visual discrimination in very young infants. Results are discussed in terms of their implications for understanding habituation, cross-modal stimulation, receptive language development, and individual differences. Appendices include data on visual fixation duration and information on…

Three projects were designed to develop and evaluate materials for use with aphasic children (perceptually handicapped with language problems). The first project presented stimulus pairs in varying modality conditions. Results suggested that, although the aphasic children were not capable of improving their auditory discrimination performance,…

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…
