This final report reviews the main theoretical and empirical developments concerning components of individual differences in human intelligence. The report is divided into three main sections. The first briefly reviews alternative approaches to understanding the nature of intelligence. The second provides the proposed componential metatheory, a…

There are two general methods of cross-validation: empirical estimation, and formula estimation. In choosing a specific cross-validation procedure, one should consider both costs (e.g., inefficient use of available data in estimating regression parameters) and benefits (e.g., accuracy in estimating population cross-validity). Empirical…

The degree to which human intelligence can be improved by psychological and educational means will depend largely upon the level of analysis accepted as representing intelligence. Training and structured learning can enhance achievement in the form of knowledge and skills. Traditional Intelligence Tests (IQ) are fairly broad samples of…

As test standards and research literature in general indicate, definitions of test bias and item bias vary considerably, as do the results of existing methods of identifying biased items. The situation is further complicated by issues of content, context, construct, and criterion. In achievement tests, for example, content validity may impose…

The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

THE OBJECTIVES OF THIS STUDY WERE TO PROVIDE NORMS FOR NEGRO CHILDREN IN THE SOUTHEASTERN UNITED STATES ON THE THIRD REVISION OF THE STANFORD-BINET INTELLIGENCE SCALE. SUBJECTS WERE DRAWN FROM THREE COUNTY SCHOOL SYSTEMS IN EACH OF THE STATES OF ALABAMA, GEORGIA, FLORIDA, SOUTH CAROLINA, AND TENNESSEE. EXAMINERS WERE TRAINED FOR UNIFORMITY OF…

RESEARCH WAS CONDUCTED TO FOCUS ON AN EXAMINATION OF SEVERAL ASPECTS OF THE CREATIVE PROCESS AS WELL AS ON THE DEVELOPMENT OF A TEST OF CREATIVE THINKING. THE SPECIFIC OBJECTIVES WERE (1) TO CONSTRUCT A TEST WHICH WILL MEASURE CREATIVITY AT THE HIGH SCHOOL LEVEL, (2) TO IDENTIFY THE VARIABLES THAT ARE EFFECTIVE IN INFLUENCING THE CREATIVE PROCESS,…

Certain modifications of a conventional test are proposed which force the item difficulty level to adjust automatically to the ability level of the examinee. The modified test is called a flexilevel test. Although different examinees take different sets of items, the scoring method provides comparable scores for all. Furthermore, the test is…

Twenty-six children ranging in age from 6 to 12 years whose tested IQ's were over 160 were tested on three Piagetian tasks of advanced concrete operations and two tests of formal operations. All children passed all concrete operations problems, but only four of the oldest boys passed the formal operations tasks. Findings are discussed in terms of…

As part of a continuing research program to improve screening of enlisted men, this study was undertaken to compare a variety of computer-simulated conventional and branching tests and to extend the theoretical analysis of branching techniques. The degree of coordination between test scores and underlying ability is used to compare conventional…

This bibliography is a list of theoretical and empirical studies of the Rasch One Parameter Logistic Measurement Model. A total of 96 entries are included. (KM)

The stability of various item discrimination indices when a particular item assumes membership within different sets of items was investigated. Results suggest that when item discrimination is used as a significant factor in determing which items from several forms will be selected for inclusion in a test, the actual items selected are less a…

A critical examination is made of standardized social studies achievement tests from a psychometric and reading perspective. Five major issues are identified that detract from the meaningful interpretation of student performance on standardized social studies tests. The issues discussed are (1) the reading dependency of social studies items, (2)…

Using ordering theory, a boolean algebraic measurement model in which item response patterns are viewed as atoms in a boolean algebra with as many generators as there are items being considered, a hierarchy-generative procedure is developed. This procedure relates to the determination of prerequisite relationships between pairs of items. An…
