Abstract
Randomly selected fifth, seventh, ninth, and eleventh graders (sixty from each grade) were givenanability test. The score and the time taken were used to test the hypotheses of no negative linear relationship and no curvilinear relationship between test score and test time. Although no significant linear relationships were found, significant curvilinear regressions of time on score were found in grades seven and nine. The strength of these significant relationships were relatively low in both grades.
