Purpose: Among many studies on the relationship between TV and schoolwork, there are only few studies that examined the influence of TV on schoolwork with other factors controlled. The purpose of this study is to examine the relationship between TV viewing and schoolwork controlling the other several factors correlated with schoolwork. Method: Subjects were ninty boys and ninty-six girls of fifth grade at the four elementary schools in the suburban area of Tokyo. The measure of the dependent variable, schoolwork, was the simple total score obtained from the second-term grade records for Natural Science, Mathematics, Japanese and Social Studies. The school records.employed the five-point grading system. The following fourteen variables were used as the independent variables. Intelligence, creativity, field dependency-independency (by embeded figure test, those who get high score are judged as field independent, vice versa.) / emotional unstability, social maladjustment, general activity, extravart / TV viewing time, books / family communication pattern (Those who get high score are regarded as conservative-conciliatory, those who get low, as critical- progressive.), parental exceeding protection, parental inconsistency/ frequency of homework, frequency of attendance at "Juku". Results: As the result of multiple regression analysis (forward stepwise inclusion method), for boys 60.1 percent of the total variation in schoolwork was explained by the highest four variables of the regression equation; intelligence, TVT (TV viewing time), EFT (embeded figure test score) and creativity. For girls, 53.9 percent was explained by EFI', intelligence and homework. Beta coefficients of of the four variables for boys and the three variables for girls were significant at .05. For girls, the correlation coefficients between TVT and schoolwork and between TVT and homework were not statistically significant, but for boys, it was found that schoolwork was under the influence of the amount of TV viewing with the variation of the other variables removed. The correlation coefficient between TVT and FCP was the highest among the correlations of TVT with the thirteen variables. The more conservative the parental attitudes, the more the amount of TV viewing increases. (2). No difference between the Radio group and the non-Radio group is found.
