SUMMARY.The study demonstrates the construct validity of a forced-choice test called Sentence Completior, Test as a measure of achievement motivation.Four hypotheses derived from McCIelIand's studies on achievement motivation and level of aspiration were tested. Excepting one, all the hypotheses were confirmed . It was found that Ss with high scores on SCT showed more positive goal discrepancy scores than others. A multivariate test of analysis of variance also revealed a significant over-all difference between the high and low n Ach groups in terms of three different measures derived from the estimated, aspired and actual scores on three psychology quizes given to eighty-five college freshmen.I .-INTRODUCTION. IN recent years, the relationship between achievement motivation ( . Ach) and goal setting behaviour has been studied for a number of non-learning tasks by McClelland and his associates (McClelland et al, 1953, p. 242-248 ;Atkinson and Reitman, 1956 ;Atkinson, 1950 ; Atkinson, 1958, p. 288-305 ;Clark, Teevan and Ricciuti, 1956). More recently, the relationship between them has also been studied in a learning situation (Kausler and Trapp, 1958 ;Ricciuti and Schultz, 1958). Most of these studies show that people with strong generalized achievement motivation usually set higher goals than those with low n achievement, particularly when the reality determinant in the level of aspiration situation is unstructured. In the present study, the same hypothesis has been tested in order to establish the construct validity of a forced-choice questionnaire, called Sentence Completion Test (SCT). The SCT has been recently proposed as a reliable and valid tool for the measurement of achievement motivation (Mukherjee, 1965~).The study primarily involved a comparison between Ss with high scores on SCT and Ss with low scores on SCT, with regard to the level of performance which they explicitly undertook to reach in three psychology examinations. It was the purpose of the study to test the null hypothesis that there is no difference between the goal setting behaviour of the high n Ach group and low n Ach group. More specifically, the experimental hypotheses investigated in this study were: (a) Ss with high scores on SCT will show more positive goal discrepancy scores " (Eysenck and Himmelweit, 1946) than Ss with low scores on SCT, (b) the difference between the two groups in terms of goal discrepancy scores will be more clear cut on the first trial (session) of goal setting than the subsequent ones when Ss are aware of their progress, (c) SS scoring high on SCT will tend to raise their aspiration level when their actual performance is relatively poor. Those performing well, on the other hand, will show a positive but a relatively lower goal discrepancy score compared to the poor performers. Ss scoring low on the SCT, on the other hand will show no such shift in their goal setting irrespective of their actual performance on the psychology examination. As such, there will be an inverse relationship between " * The research repo...
