Paper delivered in part at the annual meeting of the American Psychological Association in September, 1965.

Based on the premise that the quality of domain-specific knowledge is the main determinant of expertise in that domain, an examination was made of the shift from considering general, domain-independent skills and procedures, in both cognitive psychology and artificial intelligence, to the study of the knowledge base. Empirical findings and…

This paper presents the results of a study which examined heritability ratios for the major ethnic and socioeconomic groups in the Los Angeles Unified School District. Scores on three measures (the Cooperative Primary Reading Test, the Comprehensive Test of Basic Skills, and a composite set of intelligence tests) were compared for twins from…

THE INTELLECTUAL TEST DIFFERENCES BETWEEN NEGRO AND WHITE FIRST- AND FIFTH-GRADERS OF DIFFERENT SOCIAL CLASSES WERE CONSIDERED. THE LORGE-THORNDIKE, LEVEL I, PRIMARY BATTERY WAS USED FOR FIRST GRADERS, AND LEVEL III FOR FIFTH GRADERS. IT WAS CONCLUDED THAT RACE INFLUENCE TENDS TO BECOME MORE MANIFEST AND CRUCIAL AS THE SOCIAL CLASS LEVEL…

THIS BIBLIOGRAPHY LISTS MATERIAL ON VARIOUS ASPECTS OF HUMAN INTELLECT. APPROXIMATELY 50 UNANNOTATED REFERENCES ARE PROVIDED TO DOCUMENTS DATING FROM 1955 TO 1966. BOOKS, REPORTS, JOURNAL MATERIALS, AND SOME UNPUBLISHED TITLES ARE LISTED. SUBJECT AREAS INCLUDED ARE (1) INTELLECTUAL DEVELOPMENT, (2) ABILITY DIFFERENCES BETWEEN INDIVIDUALS, RACES,…

FOUR COMMONLY USED INDIVIDUAL INTELLIGENCE TESTS ARE DESCRIBED. DESCRIPTIONS OF SUBTESTS ARE GIVEN, ALONG WITH EXPLANATION OF WHAT EACH TEST MEASURES. THIS INFORMATION IS PROVIDED TO ASSIST THE TEACHER IN IDENTIFYING SPECIFIC ABILITIES AND WEAKNESSES IN INDIVIDUAL CHILDREN. (JW)

The student sought to identify positive factors which might be used to increase the performance levels of students in vocational classes and to investigate the relationship between motivational characteristics (intrinsic and extrinsic) and individual performance. Subjects included students in typing and shorthand classes and their two instructors.…

This study attempted to determine whether sufficiently strong relationships existed between listening comprehension level and intelligence (as measured by individual tests) for the former to be used as a predictor of the latter. Ten boys and 10 girls randomly selected from each of grades 1, 3, and 5 were given the individually-administered…

The purpose of the study was to investigate the relationship between cognitive style and school learning among fifth-grade children. The findings indicated that cognitive styles are differentially related to school learning outcomes for both boys and girls after verbal and nonverbal intelligence have been taken into consideration. The results…

A large battery of various tests of intelligence, scholastic achievement, and short-term memory was administered to some 2,000 white, black, and Mexican American pupils in grades 4, 5, and 6 in a largely agricultural school district in the central valley of California; the 3 grades were used as separate replications. Factor analysis with oblique…

The purpose of this study was to investigate the correlation between gain on the Stanford-Binet Intelligence Test (S-B) in compensatory prekindergarten programs, and scores on the New York State Pupil Evaluation Program (PEP), Reading Section, over three years later. Four hundred and five subjects showed a correlation of 0.42 for the pre-post S-B…

The effects and interactions of 3 variables on concept learning and retention were investigated: (1) method of stimulus presentation; (2) learning process; and (3) intellectual ability. One hundred and forty-four (144) 4th graders were divided into 4 groups, each of which was further subdivided into high, middle, and low intellectual ability…

The objective of this study was to conduct an intensive investigation of the relationship between Lorge Thorndike IQ subtest and Torrance creativity subtest scores. Ss were 154 twelfth graders. First order partial correlations were about .50 between different sets of creativity subtests with different IQ subtests partialled out. Canonical…

A classification of natal influences is proposed with a model of their operation. Natal influences affect maternal capacity, maternal load, and maternal efficiency. Since maternal load is increased in twin pregnancy, results of twin studies must be generalized with caution. The method of co-twin control is exemplified by examination of a small…
