Infant visual and vocal responses to television

To provide a first assessment of television influences on infants in the naturalistic setting of the home, visual and vocal behaviors of 72 infants 6 months of age were recorded during 4 days of exposure to various components of broadcast television programs: sound only, picture only, sound plus picture, or a control stimulus of unpatterned sound plus picture. Infants looked longer at the television set during the sound-plus-picture condition than during the picture-only condition, and they looked longer during both of these patterned picture conditions than during both of the other conditions that lacked a patterned picture. Also, infants vocalized more during the picture-only condition than during the sound-only condition. These findings demonstrate that infants attend to the naturalistic presentation of television stimulation and that they respond differentially to the visual and auditory components of television. The results are discussed in terms of the question of the long-term influence on infants' social responsiveness of substantial levels of exposure to the noncontingent, quasi-social stimulation provided by television.
