The problem investigated is the contribution of non-intellectual factors, in particular the level of psychosocial maturity, to the academic achievement of the high school pupil. It has generally been shown that Intelligence and Achievement correlate. (Robbertse 1968; Moerdyk 1973). However, according to Ausubel (1968) this correlation is only moderate and he suggests that this can be attributed to the influence of other variables, such as personality traits, adjustment and interests. Robbertse (1968) has stated that Intelligence alone is not a good predictor of school achievement for all pupils, that personality is an integral part of an individual's psychological make-up and it is, therefore, imperative to look at its contribution to the prediction of achievement. Eysenck (1969) and Cattell (1966) have found low but significant correlations between various personality scales and achievement. Verhage (1977) mentioned that relatively little research has been done in South Africa to determine the relationship between non-academic factors, such as personality characteristics, and academic achievement. Psychosocial maturity as conceived in this thesis is the outcome of the process of personality development with the emphasis on the person as a healthy individual in his interaction with society. A multiple correlation technique is used to relate academic results, intelligence scores and psychosocial maturity in an attempt to improve the prediction of achievement from Intelligence by using maturity scores. Results that are generally supporting of the hypothesis are presented, and factors that emerge and their implications are discussed. The characteristics of the maturity scale as found in a South African sample are also discussed.
