To assess the effects of timed/untimed testing conditions on intelligence scores, high school students were assigned to an intelligence test under either conditions and subsequently to a battery of eight reaction time tests. Results showed that subjects scores were related to the speed with which they processed information. (JAZ)

This study investigates the nature and the factor structure of infant intelligence. The Bayley Mental Scale items were administered. According to the analysis, intelligence at any age is a set of separate mental abilities at each age, and there are a variety of paths through which mental development occurs. (JAZ)

This study introduces a measure of introspectiveness for adolescents aged 12-18 and investigates its association with several aspects of adolescent development. Results from three studies suggest that adolescent introspectiveness may originate in past family interaction, may affect current health and activity patterns, and may shape future…

Since early research had shown that a total score on 27 Piagetian tasks was very highly correlated with a Wechsler and achievement composite, a study investigated the possibility of shortening the Piagetian test by means of classical analysis methodology. (HOD)

Suggests a method of integrating user performance and attitudes toward the computer system into quality control procedures (QCP) and describes an application of user attitudes to the QPC in a class of novice computer users receiving instruction in BASIC programing language via formal classroom lecture with computer assisted instruction tutorials.…

Utilizing 11 years of University of Saskatchewan circulation transactions, it is shown that P. M. Morse's Markov model of book use fits approximately 99 percent of data for whole collection and for three subject areas; contrary to his assumptions, one of the model's parameters is time dependent. Thirteen references are included. (EJS)

Medical students' performance on simulated patient practical examinations were compared to faculty ratings of the surgical clerks and awards of honor ratings. Faculty ratings were correlated with objective measures of the criteria on the exams. The performance of honor, versus non-honor students was higher on the practical exam. (Author/GDC)

Results suggest that, without competing motivational forces, students high in communication apprehension (CA) spend less time talking than do students in low CA. (PD)

College students (n=491) were sampled to determine the extent to which attitudes toward mathematics can be viewed as reflections of other personality characteristics, as opposed to manifestations of a single underlying attitude toward mathematics. (Author/PN)

Correlations between the achievement test scores of 2,000 entering freshmen in 1977 and measures of college performance were similar to those reported for tests of the college entrance type. These results provide support for the predictive validity of the Iowa Tests of Basic Skills and the Iowa Tests of Educational Development achievement test…

Describes a study which analyzed problem solvers' error detection processes by instructing subjects to think aloud when solving statistical problems. Effects of evaluative episodes on error detection, detection of different error types, error detection processes per se, and relationship of error detection behavior to problem-solving proficiency…

Investigated whether an association exists between quietness in children and rejection of these children by their peers. Collected data from 1,529 children in grades three through 12. Found a strong tendency on the part of children to reject shy or quiet peers. (PD)

The relationship between psychometric intelligence and rapid acoustic information processing was explored in two experiments using college students. Group differences occurred in threshold interstimulus intervals required for recognition and in speed. Results were interpreted as indicating better information processing efficiency (higher…

The hierarchical and radex models of ability organization are shown to be parallel. Both suggest a complexity continuum for cognitive performance tasks which, in the radex model, corresponds to the general-to-specific dimension in factor analyses. The bases for this continuum indicate its importance for theories of intelligence. (Author/RD)

Longitudinal data collected on English adolescents were used to determine the extent to which socialization processes in the family were related to the cognitive and affective behavior of the adolescents. (Author)
