In the present paper, we develop and apply a technique, based on the logic of process dissociation, for obtaining numerical estimates of item and order information. Certain variables, such as phonological similarity, are widely believed to produce dissociative effects on item and order retention. However, such beliefs rest on the questionable…

Higher-order latent traits are proposed for specifying the joint distribution of binary attributes in models for cognitive diagnosis. This approach results in a parsimonious model for the joint distribution of a high-dimensional attribute vector that is natural in many situations when specific cognitive information is sought but a less informative…

Spearman's ''Law of Diminishing Returns'' (SLODR) predicts that "g" saturation for cognitive tests will be lower at high ability levels than at low ability levels. This hypothesis was tested in two large samples of Danish military draftees (n=33,833 and n=25,020). The subjects were representative samples of the young adult male…

Four experiments tested the predictions made by the model outlined in A. H. Criss and R. M. Shiffrin (2004b). Participants studied 2 successive lists of pairs followed by a recognition memory test for the most recent list. Some items and some pairs were repeated across the 2 lists. Critically, a given item could be repeated in the same or…

A decade ago, Bechara et al. [Bechara, A., Damasio, A. R., Damasio, H., & Anderson, S. W. (1994). Insensitivity to future consequences following damage to human prefrontal cortex. "Cognition, 50," 7-15] published a paper in Cognition, introducing a Gambling Task which was designed to mimic everyday decision-making. Since then, the task has been…

Selected cognitive science methods were used to modify existing test development procedures so that the modified procedures could in turn be used to improve the usefulness of job knowledge tests as a proxy for hands-on performance. A plan-goal graph representation was used to capture the knowledge content and goal structure of the task of using a…

Designed to measure children's abilities to synthesize concepts from several sources, this measure is based on the assumptions that children move from the concrete to the abstract, from specific to generic, and that the ability to synthesize and form new concepts is an important prerequisite to reading comprehension. Each form of the test is…

Several dimensions of impulse control (i.e., delay of gratification, reflectivity, and motor control) were related to intelligence, mental status, and adjustment among 91 institutionalized aged women. The findings suggest that impulse control in its various forms has a consistent and significant relationship with indices of adaptation. (Author)

The Quick Test, Form I (QT) and the Stanford-Binet Intelligence Scale, Form L-M (SB) were administered to 70 preschool children. Results raise serious doubt about the validity of the QT functioning. Further research is indicated. (Author)

Although role or perspective taking has been considered important for the development of mature social thought and behavior, and training for perspective taking has been used to remediate deficient behavior, few studies with either normal or disturbed populations have examined naturally occurring behaviors expected to correlate with…

To better determine the cognitive abilities needed for computer programming, a study was done using 41 junior and senior level college students majoring in social and behavioral sciences at a Los Angeles area university. The subjects were first tested to determine their cognitive abilities with regard to spatial ability, field…

Research based on author's doctoral dissertation, submitted to the Graduate School of the University of California at Los Angeles.

An overall rationale for the early identification of strengths and possible developmental weaknesses in school beginners is presented in Part I, with the research-based areas of assessment of tests for auditory analysis skills, conceptual skills and language skills. The general purposes of diagnostic assessment and a model of a behavioral…

An analysis of scatter among the Tests of Cognitive Ability for the Woodcock-Johnson Psycho-Educational Battery was conducted on scores of 3,566 grade 1 through 12 students from the standardization sample. Large mean high subtest-low subtest differences were noted for each grade level and compared to Wechsler Intelligence Scale for…
