Overstatement in third-grade children

Abstract

An overstatement test, composed of an "assertion" test and an "execution" test, was given to 271 children in third-grade classes. The data secured were the children's overstatement scores (secured by dividing total number of subject's assertions by total number of successes in execution test; average correlation with M.A. + 0.29, with C.A. as a whole, + 0.03); teachers' character rankings (average reliability coefficient + 0.69; average correlation with M.A. + 0.25, with school achievement, + .0.37); validity coefficients (average, + 0.50—with M.A. constant, + 0.48; with achievement constant, + 0.44). The Brown-Spearman reliability coefficient for the test was + 0.71. The average correlation between achievement and M. A. was + 0.40, between achievement and overstatement, + 0.39.
