Person and situational determinants of cognitive ability test performance and subjective reactions were examined in the context of tests with different time-on-task requirements. Two hundred thirty-nine first-year university students participated in a within-participant experiment, with completely counterbalanced treatment conditions and test…

Background: Most standardized intelligence tests require more than 1hour for administration, which is problematic when evaluating individuals with intellectual disabilities and developmental disabilities (IDDD), because a significant proportion of these individuals can not tolerate lengthy evaluations. Furthermore, most standardized intelligence…

The development of a short form of the Raven Advanced Progressive Matrices Test is reported. Results from 3 studies with 663 college students indicate that the short form demonstrates psychometric properties similar to the long form yet requires a substantially shorter administration time. (SLD)

In this study, simulated and actual Air Force test data were used to compare the different procedures for equating mental tests: conventional (equipercentile and linear), Item Response Theory (IRT), and strong true-score theory (STST); data collection designs used were single-group, equivalent-groups, and anchor test. Equating transformations were…

The advantages that computer adaptive testing offers over linear tests have been well documented. The Computer Adaptive Test (CAT) design is more efficient than the Linear test design as fewer items are needed to estimate an examinee's proficiency to a desired level of precision. In the ideal situation, a CAT will result in examinees answering…

Research on the comparative utility of varying numbers of rating statements per set--using an external criterion of recognition of rater profiles for evaluating "goodness" of the sets--was conducted on 132 noncommissioned Air Force officers. Groups of subjects rated groups of their peers on 20 factors, on a subset of 10 factors, and on a…
