The findings of six studies based on in-home observations of children's television viewing behavior as recorded by mothers, fathers, or other adults caring for the child are summarized and compared. The object of this research method is to determine child interest in the programs, the variability of interest within programs, the amount of series interest in relation to the number of programs, the amount of viewer interest, questioning behavior, and the type of questions raised. This procedure, which has proven useful for children aged three to seven, has been used in samples varying from 150 to 600 subjects. A discussion of the generalizability, reliability, and validity of the results obtained with this method concludes the report. (RAO)
