While stepwise regression analyses revealed that the demographic variables of sex, school ability, age, and father's occupation increased the power of prediction the LTIT alone was judged to be a valid predictor of academic achievement. (Author)

Q-type factor analysis was used to re-analyze baseline data collected in 1957, on 47 men aged 65-91. Q-type analysis is the use of factor methods to study persons rather than tests. Although 550 variables were originally studied involving psychiatry, medicine, cerebral metabolism and chemistry, personality, audiometry, dichotic and diotic memory,…

This study investigates the effect of curiosity in first and second grade children as an individual difference variable in learning in a computer-based interactive learner control environment and discusses the implications for instructional designers and educators.
