This study analyzes the impact on earnings of human-capital obsolescence, human-capital deterioration, unstructured on-the-job learning, and structured on-the-job learning. The study defines these four concepts, discusses their determinants, and analyzes the market mechanics by which each influences earning rates. A model is developed and adapted…

The 30 papers in the area of educational statistics that were presented at the 1972 AERA Conference are reviewed. The papers are categorized into five broad areas of interest: (1) theory of univariate analysis, (2) nonparametric methods, (3) regression-prediction theory, (4) multivariable methods, and (5) factor analysis. A list of the papers…

The sign test is perhaps the simplest nonparametric procedure comparable to the commonly used parametric t-test. This test is easily applied which makes it useful preliminary analysis and for the analysis of data of passing interest. A large variety of its applications to education research, usually not found in the standard textbooks, is included…

In this study, two hypotheses were tested: (1) Self-report data are unrelated to behavior change; (2) Exposure to competent models of open and helpful behavior increases this skill performance in an encounter group. Two encounter groups were conducted with 18 college students who had the incentive to become more open, honest, and helpful. One…

One approach to the problem of analyzing classroom interaction by use of a Markoff chain is presented. The two sections of the paper present (1) a discusion of Hoel's test of order of a Markoff chain, and a Likelihood Ratio Criterion (LRC) for a two-dependent Markoff chain is given, and (2) a discussion of possible adjustments of Darwin's LRC with…

A semantic differential processing system was designed to economically facilitate the collection and analyses of large amounts of data. The collection form was designed on an optical scanning form which may be overprinted with random orderings of concepts, scales, and scale polarities. A FORTRAN program "unscrambles" the scale responses.…

A project was conducted to develop a series of studies that will enable one to measure attitudes with reasonable accuracy. Nine stages of project activity were identified: design optical scanning form; write computer program to analyze data; determine adjective pairs; factor scales on elementary pupils; factor scales on high school students and…

A description is given of a general method for studying partitions. The main focus is with the analysis of relationships among several different partitions of the same items for the explorations as well as confirmation of structural relationships. A partition is defined as a set of mutually exclusive clusters of items; however, this paper deals…

The Rasch model and other latent trait models encounter some difficulty when faced with an appreciable amount of missing data or omitting behavior. The present note assumes that some reasonable missing data model has been formulated which does not involve the parameters associated with the latent ability of interest. A maximum likelihood function…

THE AIM OF THIS STUDY WAS TO DEVELOP, DEMONSTRATE, AND EVALUATE THE FEASIBILITY OF A PARTICULAR MODEL FOR A STUDENT ACCOUNTING SYSTEM AT THE UNIVERSITY OF TEXAS, INCORPORATING PREVIOUSLY COLLECTED INFORMATION PLUS ADDITIONAL QUESTIONNAIRE DATA FROM STUDENTS. A CENTRAL DATA BANK WAS ESTABLISHED TO INCLUDE (1) THE ACADEMIC RECORD OF THE STUDENT…

The purpose of the present study was to directly assess the strength and stability of acoustically mediated word associations under conditions which should maximize their occurrence. (Author)

The present study reports data obtained from chronic schizophrenic patients which relate formal categories of language behavior to performance on the Stroop Color-Word Interference Test--a task of verbal encoding under distracting and nondistracting conditions. (Editor)

To test a theory that selective attention to threatening stimuli induces paranoia, an attempt was made to manipulate attention to threatening and nonthreatening statements among college students and examine the effects on three indices of paranoia. (Editor)

The purpose of this study was to investigate the relationships among nine relatively independent factors of attitude toward quantitative concepts and measures of quantitative and verbal aptitudes. (Author)

In the present study the relationships between the amount of freedom given the learner in choosing a learning task and his subsequent performance and persistence on that task were investigated. (Author)
