Purpose: This study investigated the relationship between hearing loss and memory and attention when nonverbal, visually presented cognitive tests are used. Method: Hearing loss (pure-tone audiometry) and IQ were measured in 30 participants with mild to severe hearing loss. Participants performed cognitive tests of pattern recognition memory,…

It was hypothesized that there are significant differences in intellectual patterns between black and white populations which can be demonstrated on the Wechsler Adult Intelligence Scale (WAIS). A one-way analysis of variance was performed on the subjects' scores on the WAIS subtests and the Verbal, Peformance and Full Scale IQ using the ethnic…

Sex differences in variability in the national norms of the Differential Aptitude Tests, Preliminary Scholastic Aptitude Test/Scholastic Aptitude Test, Wechsler Adult Intelligence Scales, and California Achievement Tests were examined. Compared to females, males were consistently more variable in quantitative reasoning, spatial visualization,…

School psychologists' perceptions of how reading disabilities (RD) should be operationalized were examined and compared to those of journal editorial board members in the learning disabilities field (Speece & Shekitka, 2002). Participants were practicing school psychologists drawn from the membership directory of the National Association of School…

Individual differences in reading and cognitive processing among a sample of generally poor readers were studied in order to answer two major questions: Do they have a specific cognitive style that favors global-simultaneous strategies and a weak sequential strategy? If they do not have a distinct cognitive style or strategy, but are merely poor…

This report summarizes the work conducted for the Artificial Intelligence Measurement System (AIMS) Project which was undertaken as an exploration of methodology to consider how the effects of artificial intelligence systems could be compared to human performance. The research covered four areas of inquiry: (1) natural language processing and…

Children were tested on the WPPSI and Stanford-Binet and after three years they were tested on the WISC. Results indicate that the WISC scores were significantly higher than the two other tests. The results of the various subtests of the three tests are compared and discussed. (SE)

The increasing automation of many occupations leads to jobs that involve understanding and monitoring the operation of complex computer systems. One case is PATRIOT, an air defense surface-to-air missile system deployed by the U.S. Army. Radar information is processed and presented to the operators in highly abstract form. The system identifies…

Arguing that goal knowledge is as important to intelligent machine activity as it is to human activity, and that it also must be well understood and explicitly represented in an instructional system if that system is to be successful in fostering learning, this report presents an architecture for intelligent tutors that explicitly represents…

Procedural semantics models have diminished the distinction between data structures and procedures in computer simulations of human intelligence. This development has theoretical consequences for models of cognition. One type of procedural semantics model, called schema theory, is presented, and a variety of cognitive processes are explained in…

INTELLECTUAL, EDUCATIONAL, NEUROLOGICAL, PHYSIOLOGICAL, PSYCHOLOGICAL, AND SOCIOLOGICAL FACTORS IN VARIOUS PATTERNS OF INTERRELATIONSHIPS INFLUENCE THE THINKING PROCESS. INDIVIDUALS DIFFER IN THE CONCEPTS THEY HOLD AND IN THEIR USE OF THESE CONCEPTS BECAUSE OF VARIATIONS IN INTELLIGENCE AND BACKGROUND OF EXPERIENCE. THE RANGE AND LEVEL OF CONCEPTS…

THE EXAMINATION WAS CONDUCTED TO DETERMINE IF A CHILD'S ABILITY TO CREATE (COGNITIVE ORIGINALITY) IS INDEPENDENTLY ASSOCIATED WITH HIS GENERAL LEVEL OF INTELLIGENCE. ONCE THIS PROVED TO BE THE CASE THE INVESTIGATORS THEN PURSUED THE STUDY OF PSYCHOLOGICAL CORRELATES THAT DISTINGUISH INDIVIDUAL DIFFERENCES ON THE CREATIVITY AND INTELLIGENCE…

EARLY FORMS OF NUMERICAL REASONING WERE INVESTIGATED BY EXAMINING THE ROLE OF A SET OF VARIABLES IN THE DEVELOPMENT OF CONSERVATION OF NUMBER. CONSERVATION OF NUMBER WAS DEFINED AS THE RECOGNITION THAT THE NUMBER OF OBJECTS CONSTITUTES AN AGGREGATE WHICH IS NOT CHANGED MERELY BY REARRANGING THEM. EXPERIMENT ONE WAS CONDUCTED WITH CHILDREN FROM…
