Computer analysis of intellectual skills

In the majority of psychological tests the items are arranged in an empirically determined hierarchy of increasing difficulty, through which the subject works until he reaches the upper limit of his ability. Items are generally scored on a pass or fail basis, and although there is redundancy in the data collected there is relatively little information as to how the level of performance was attained. The present paper describes a process control program which overcomes some of the problems involved. In the example presented the program controls the presentation on a graphic display of a psychological test which is particularly suitable for computer analysis and design, and the advantages of this type of test are briefly described and discussed.
