The theoretical and methodological concepts for research on aptitudes as cognitive processes are discussed. Individual differences constructs are reviewed in relation to cognitive processing models, and studies of short-term memory are reviewed. A coordinated approach to the study of aptitude as information processing is recommended. (Author/RD)

The experience of developing a set of comprehensive aptitude batteries for computer administration for the Air Force Human Resources Laboratory's Learning Abilities Measurement Program resulted in the formulation of nine principles for creation of a computerized test battery. These principles are discussed in the context of research on…

In four experiments to replicate and extend the findings of Shuell and Keppel (EJ 016 150), "fast" and "slow" learners were brought to a similar learning criterion, with the result that their forgetting curves were parallel. The experiments involved American and Nigerian students in learning word lists and poems. (Author/CM)

Two studies investigated whether instructing students to organize recall would differentially facilitate performance of "fast" and "slow" learners (defined from pretest recall performance). Instructions to employ alphabetic organization facilated performance of both groups to the same extent, whereas categorical organization facilitated slow…

The functions that IQ and aptitude tests now serve in schools and the trends that may modify the present pattern of test use are presented. Current research on intelligence and aptitude and the kind of intelligence tests that might prove more useful in instructional planning are also discussed. (Author/RD)
