In administration of individually administered intelligence tests, items are commonly presented in a sequence of increasing difficulty, and test administration is terminated after a predetermined number of incorrect answers. This practice produces stochastically censored data, a form of nonignorable missing data. By manipulating four factors…

As item response models gain increased popularity in large-scale educational and measurement testing situations, many studies have been conducted on the development and applications of unidimensional and multidimensional models. Recently, attention has been paid to IRT-based models with an overall ability dimension underlying several ability…

Investigates the power of a macropropositional model of comprehension for a complex social interaction (a rape interrogation) to predict accurate recall by both individuals and groups. The findings are considered in relation to strategic models of discourse comprehension, and the implications for future social psychological research are discussed.…

Simulated Occupational Choice (SOC) was developed to measure competencies in career decision-making. SOC is a structured, individually-administered simulation exercise designed to elicit career decision-making behaviors and enable those behaviors to be observed, recorded, and scored in meaningful ways, particularly for diagnosis. It was…

Monte Carlo simulation procedures were used to study the psychometric characteristics of two two-stage adaptive tests and a conventional "peaked" ability test. Results showed that scores yielded by both two-stage tests better reflected the normal distribution of underlying ability. Ability estimates yielded by one of the two stage tests…

Three and one-half years of research on computerized ability testing are summarized. The original objectives of the research were: (1) to develop and implement the stratified computer-based ability test; (2) to compare, on psychometric criteria, the various approaches to computer-based ability testing, including the stratified computerized test,…
