The study experimentally tested the relationship between visual attention and comprehension of a TV program. 72 5-year-old children watched a 40-min version of the TV program "Sesame Street." Half the children viewed the program in the presence of a variety of toys and half viewed without toys. The children were then tested for their comprehension of the program. Although visual attention to the TV in the no-toys group was nearly twice that in the toys group, there was no difference between the groups in comprehension. There were, nevertheless, significant within-group correlations between visual attention and comprehension even for questions concerning only auditorily presented material. The results were interpreted as indicating that in a normal TV viewing setting, variations in the comprehensibility of the TV program may determine variations in children's attention to the TV.
