Abstract

The Lorge-Thorndike Intelligence Tests, verbal and nonverbal, were administered to 115 eighth-grade boys and 150 eighth-grade girls who had taken the tests in grade three or four. Estimated true changes in IQ from grades three and four to grade eight were calculated. It was found that 1) estimated true (E.T.) nonverbal changes were more than three times as great as (E.T.) verbal changes for both boys and girls, 2) both verbal and nonverbal IQ scores tended to rise, 3) grades three, four, and eight verbal IQ scores correlated more highly with each other than did grades three, four, and eight nonverbal IQ scores, and 4) there was no significant product moment correlation between (E.T.) verbal and (E.T.) nonverbal IQ change scores.
