The present study investigates the impact of sibling pairs' friendly or unfriendly viewing styles on the younger siblings' understanding of the content of television programs. A total of 19 sibling pairs were videotaped as they viewed one of two television programs. The younger child in all of the pairs was in first or second grade. Fourteen of the older siblings were more than 3 years older, and five were 1 or 2 years older than their younger siblings. All of the children saw a "Fat Albert" cartoon and an episode of the situation comedy "One Day at a Time." Results indicate that young children who viewed the age appropriate program with a sibling with whom they were unfriendly were better able to interpret that program than were young children who were friendly with their siblings. For the adult program, however, both children from the companionable pairs scored about equally, while those young children from the unfriendly pairs scored quite a bit lower than their older siblings. The disparity of the unfriendly siblings' scores suggests that they interpreted the program independently of one another, whereas the equality of the friendly siblings' scores indicated that the younger sibling may have benefitted from viewing with the older sibling.
