The Effects of Background Television on the Quantity and Quality of Child-Directed Speech by Parents

Prior research has identified negative effects of background television (TV) exposure on toddler toy play and parent–child interactions and has documented a negative association between early TV exposure and language development. It is hypothesized that background, adult-directed TV reduces the quantity and quality of parent language addressed to their young children. To test this hypothesis, the current study compared parent language directed at 12-, 24-, and 36-month-old toddlers (N = 49) in the presence and absence of background TV. In the presence of background TV, the number of words and utterances spoken per minute by the parent decreased as did the number of new words per minute. However, mean length of utterances did not differ. Because parent input is an important factor for language acquisition, development may be negatively affected by background TV exposure.
