Four age levels of the population: 9, 13, 17, and young adult (25-35) were sampled. This publication contains a preface in which Robert H. Carleton reacts to NAEP and presents the NSTA's perspective of the project, a…

The job of Steel Mill Inspector was analyzed in terms of the sequential constraints existing among the job's operations. This measure of environmental variability was related to cognitive complexity--a measure of the individual Inspector's ability to process job-related information. As predicted, satisfaction with the work itself was an inverted…

Nine studies are summarized which investigated the relation between attributes of performance as perceived by the subject and corresponding objective measurements. The attributes studied were: (1) intellectual activity perceived to be involved when dealing with a task (Studies 1 and 2), and (2) perceived difficulty (Studies 4 to 9). Study 3…

Reported is a study of the relationships between scholastic grades of 419 junior and senior high school students and their ability to perform formal operational tasks. A Piagetian Task Instrument (PTI) was constructed to assess the formal thinking ability of the students. Face validity of the instrument was obtained after a literature review.…

The purpose of this study was to prepare a descriptive analysis of the relationship existing between selected Nebraska school administrators and vocational education. Following a review of literature, 51 superintendents and 51 principals from three size categories of schools were randomly selected and personal and professional information was…

As part of an ongoing longitudinal study of early cognitive, affective, and social development in economically disadvantaged children, this investigation assessed the classroom behavior of 500 urban preschool children from Portland, Oregon, St. Louis, Missouri, and Trenton, New Jersey. The majority were black and enrolled in Head Start. Primary…

FACTOR ANALYSIS WAS CONDUCTED ON SEVERAL COGNITIVE ABILITIES IN AN EFFORT TO RELATE THESE ABILITIES TO TASKS OF CONCEPT ATTAINMENT AND INFORMATION PROCESSING. THE ABILITIES UNDER CONSIDERATION WERE DESCRIBED AS GENERAL REASONING, VERBAL COMPREHENSION, INDUCTION, DEDUCTION, SPATIAL SCANNING, PERCEPTUAL SPEED, ROTE MEMORY, AND SPAN MEMORY. ABILITY…

Discusses a study designed to specify the interpersonal communication related determinants of anomia within a close friendship context. (MH)

An in vitro flooding package was used to treat the posttraumatic stress disorder of a 10-year-old girl. Traumatic scenes were identified and stimulus and response imagery cues were presented according to a multiple baseline across traumatic scenes design. Postreatment and follow-up assessment revealed the positive influence of the treatment.…

Examined the relationships among two psychometric measures of nonverbal cognitive ability - The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Psychoeducational Battery-Tests of Cognitive Ability (WJPB-TCA) and a neuropsychological test of abstract reasoning and concept formation (Halstead Category Test) in 25…

Data from the Japanese standardization of the Wechsler Preschool and Primary Scale for Intelligence were used to analyze the structure of abilities of Japanese children in terms of the Burt-Vernon hierarchical model of intelligence. It was suggested that the pattern of cognitive strengths and weaknesses that emerged would help clarify a number of…

Reports on a study into first grade student's interpretations of the equals sign in different contexts. Argues that varying situations affect students' understanding of such arithmetic concepts, including the social interaction patterns in the classroom during arithmetic instruction. (TW)

Use of the term "acceleration" to describe interventions to enhance children's intellectual potential is inappropriate, as the term cannot by justified from the standpoint of mental measurement, mental growth, genetics, or education. Maximizing a child's potential through creation of stimulating environments is recommended rather than…

Borkowski and Krause (1983) concluded that the locus of black-white intelligence differences lies in metaprocesses not elementary cognitive processes. However, some variables were difference scores with unacceptably low reliability. Magnitude comparisons of racial differences give a different picture of results; comparable differences in measures…
