This study examined computerized adaptive testing and cognitive ability testing of adults with cognitive disabilities. Adult subjects (N=250) were given computerized tests on language usage and space relations in one of three administration conditions: paper and pencil, fixed length computer adaptive, and variable length computer adaptive.…

This study validated computerized versions of selected tests from the Kit of Factor-Referenced Cognitive Tests of 1976, compared performance of higher education students on computerized and paper-and-pencil versions of the tests, and explored whether gender, academic status, or age interacted with the tests.

The repeated psychological assessment of 41 high-risk infants during the first 2 years of life using the Mental Scale of the Bayley Scales of Infant Development was investigated. Analyses indicated that the infants' cognitive functioning remained fairly stable over the 2 years, particularly from age 6 months on. (Author/JDD)

Proposes a systemically valid testing system that induces curricular and instructional changes in education systems to foster the development of the cognitive traits that tests are designed to measure. Analyzes test characteristics and outlines the principles of a systemically valid testing system. (FMW)

This study evaluated the Bielefeld Developmental Test for Blind Infants and Preschoolers by comparing cognitive performance of blind and sighted children (ages three and four). Results indicated that even this test (with "blind-neutral" items) did not permit a fair comparative assessment, though it did prove suitable for within-group…

Two factors which act to depress cognitive test performance are referred to as anxiety and boredom. The responses to a 20-item adjectival checklist administered to high school seniors after completing a cognitive test battery were subjected to iterative principal axes factor analysis. The relationships between anxiety or boredom and test…

This study assessed use of five computerized analogy problems as a measure of mental speed with 62 children (ages 3-13) with mild/moderate mental retardation. Results found medium to high correlation between scores on the tasks and other cognitive measures and the adaptive behavior scale. The value of assessing cognitive speed in the cognitive…

Researchers have attempted to develop paper and pencil Piagetian tests that yield results equivalent to manipulative Piagetian tasks and that can be administered in significantly less time. This study is an attempt to partially replicate and extend the findings of research by Paul Ankeny and Lyle Joyce who found significant positive correlations…

Because eligibility for speech-language services often is based on the relationship between the child's cognitive ability and language performance, this study examined the agreement of measurement practices used in the cognitive referencing model of eligibility determination. Administration of 5 measures to 26 preschool children with delayed…

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

Discusses the evolution of current decision support systems (DSS) computer software and their potential for use in assessing cognitive ability. Current applications of computer software for structured and unstructured problem solving are examined together with the feasibility of computerized adaptive testing. Characteristics of computer-based…

This study examined the stability over 1-year and 2-year periods of the relationship between a cognitive measure and 2 language measures in 125 children (ages 3-7) with developmental delays. Findings indicated substantial changes in the cognitive-language relationship over time, suggesting that the discrepancy model is not appropriate for service…

This study compares the fit of the 3-parameter model to the Ability Removing Random Guessing (ARRG) model on data from a wide range of tests of cognitive ability in three representative samples. When the guessing parameters under the 3-parameter model are estimated individually for each item, the 3-parameter model yields the better fit to…

The predictive validity of the revised Graduate Record Examination Analytical Test (GRE-A) was compared with the experimental form of the GRE-A, in terms of graduate school admissions as well as advancement to Ph.D. candidacy decisions. Prior to 1974 the Graduate Record Examination included just a verbal and a quantitative test; in 1974 it was…
