Computer simulation was used to assess the effects of item parameter estimation errors on different item selection strategies used in adaptive and conventional testing. To determine whether these effects reduced the advantages of certain optimal item selection strategies, simulations were repeated in the presence and absence of item parameter…

Karl Bruhn, professor of education at Helsinki University for almost 20 years, in addition to writing a history of education, concentrated particularly on carrying out further investigations with his Helsinki Test which was publicly released in 1953. The use of this test is presented in this posthumous article by Bruhn. The Helsinki Test is a…

This discussion of the design of computerized psychological assessment or testing instruments stresses the importance of the well-designed computer-user interface. The principles underlying the three main functional elements of computer-user dialogue--data entry, data display, and sequential control--are discussed, and basic guidelines derived…

A functional design model for a computerized adaptive testing (CAT) system was developed and presented through a series of hierarchy plus input-process-output (HIPO) diagrams. System functions were translated into system structure: specifically, into 34 software components. Implementation of the design in a physical system was addressed through…

Developed as a guide to resources in the Robert E. Kennedy Library at California Polytechnic State University, this bibliography includes a selective listing of books, microfiche, and reference materials on the topic of educational and psychological testing. The publications included either contain sample or entire test items, and…

The present study investigated the efficiency of various existing measures, mainly psychological tests, for predicting job performance of mentally retarded workers in a sheltered occupational shop. Results indicated that existing measures are predictive of performance on some but not all jobs in a sheltered workshop. (Author)

Subjects were asked to encode and recall lists of words under the influences of marijuana and a marijuana placebo. Free recall was more complete when both encoding and recall were after marijuana use than in the encode-marijuana, recall-placebo state. Recall must depend on restoration of dissociated encoding state. (CHK)

Using the Hutt Adaption of the Bender-Gestalt Test (HABGT), this study explored the test-retest reliability of the scale with forty process schizophrenics over a two week interval. (Author/DEP)
