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…

Two procedures for the display of item analysis statistics are described. One procedure allows for investigation of difficulty; the second plots item difficulty against item discrimination. (Author/JKS)

A procedure for estimating the reliability of a factorially complex composite is considered. An application of its use with Scholastic Aptitude Test data is provided. (Author/JKS)

An example of how quantitative research methods and qualitative methods can complement each other in the service of inquiring into classroom learning environments. (Author/MLF)

Assessed the psychometric structure of a neuropsychological test battery in order to assist in understanding the predictive and descriptive components in the diagnosis of organic brain disturbance. The methods chosen were both linear and nonlinear, factor analysis and hierarchical cluster analysis. (Author)

The major thesis of this research is that there are two types of processes underlying verbal performance. First, there are processes based on knowledge. Second, verbal performance requires the exercise of certain information-free, mechanistic processes, i.e., those that are conducted on the physical representation of a symbol (including whatever…

Some forms of interviewing are reviewed briefly, with emphasis on a method of assessing the reliability of interview ratings. Ways for introducing validity and meaning to academic or employment selection procedures that use interview techniques are suggested. (LBH)

Two studies of performance in psychometric tests of mechanical ability are described. The subjects included a total of 70 undergraduates. Results allowed identification of subjects' rules of mechanical reasoning that accounted for variations in performance according to mechanical ability. (TJH)

The relationship between speed of information processing and Intelligence Quotient (IQ) was examined in 62 college students using timed paper-and-pencil substitution tests to measure processing speed. A psychometrically better IQ test showed a strong linear relationship between mean time to code and its correlation with IQ; this relationship was…

Considered techniques to assess self-reported drug use. Evaluated the effects of different response options on the distribution, reliability, and validity of scores on drug-use items. Suggests that more quantitative measures are not necessarily more reliable or valid than less quantitative measures of drug use. (Author/KS)
