Mothers of 126 infants, 54 lower-socioeconomic status (SES) infants (26 younger, 4–11 months; 28 older, 12–19 months) and 72 middle-SES infants (12–17 months), answered questionnaires about their infants' typical television (TV) watching and interest, the frequency of their independent play with toys and dyadic play with and without toys, and whether or not the TV was typically on in the room at the time. Although infants spent little time actively watching TV, the majority of mothers in all groups reported the TV typically turned on in the room at least half the time during all types of play. Mothers reported middle-SES infants engaged more frequently in individual and dyadic toy play, but lower-SES infants were more often exposed to background TV/video during play. Because play is important to infant development and background TV can disrupt it, these findings raise concerns, particularly for infants residing in lower-SES households.
