The majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981)…

The article presents the feature sampling signal detection (FS-SDT) model, an extension of the multivariate signal detection (SDT) model. The FS-SDT model assumes that, because of attentional shifts, different subsets of features are sampled for different presentations of the same multidimensional stimulus. Contrary to the SDT model, the FS-SDT…

The Yudofsky scale is considered to be one of the best scales for measuring aggressive behavior developed to date. One of the chief shortcomings of the scale, however, is appropriate methods for scoring it in ways that make the resulting scores well-suited for data analyses. The basic scoring problem with the Yudofsky scale is that the scale is…

General intelligence ("g") is one of the most important, and least understood, phenomena in psychometric psychology. Yet "g" is an issue that is largely ignored in cognitive studies of aptitude. In the current paper, an attempt is made to bridge the gap between psychometric data and cognitive theory, using two major performance…

Psychometric issues confronted when implementing a system of item response theory (IRT) tools for test development at the Educational Testing Service (ETS) are discussed. These issues include selecting and assessing the appropriateness of IRT models, choosing methods of IRT scaling for item pools, considering test scoring strategies, and applying…

In efforts to clarify ambiguity in the scoring directions for part of the WISC, 100 children were given the test which was scored by two sets of criteria. Four sets of data were analyzed, with significant discrepancies apparent only between Verbal-Performance correlations secured by Wechsler in his standardization of the WISC and those secured in…

A discussion of models of intellectual development and their application to education identifies the two major groups of such models and examines recent attempts to combine them. The two types of theories are described as the psychometric models, which see intellectual growth as the incremental amassing and associating of discrete ideas, and the…

QUESTION-STUDY AS A METHOD FOR INTERPRETING AND MEASURING PROBLEM-SOLVING BEHAVIOR WAS STUDIED. DATA WERE OBTAINED FROM A PREVIOUS STUDY (ED 003 005) AND ANALYZED. ANALYSES WERE PERFORMED TO DETERMINE WHETHER QUESTIONS WERE MORE USEFUL FOR ASSESSING PROBLEM-SOLVING BEHAVIOR THAN ANALYSIS OF SOLUTIONS. TECHNIQUES, FORMULAE, AND RESULTS PERTINENT TO…

This report tells of the procedures and results of a psychophysical study of 28 3.8-year-old-boys from the Harlem Training Center. In spite of an experimental situation that was something of an ordeal, some meaningful data was generated. The main area investigated in this study was the evoked-response indices of temporal processing, that is, the…

The 25-item Teaching Anxiety Scale (TCHAS(1)-29) is provided, together with the Teaching Anxiety Scale (TCHAS(1,2)-25) Item-Pair Directory, showing the correlation between item numbers in the two equivalent forms of the scale. (For related document, see TM 002 928, 930). (DB)

Omitted items cannot properly be treated as wrong when estimating ability and item parameters. A convenient method for utilizing the information provided by omissions is presented. Some theoretical and considerable empirical justification is adduced for the estimates obtained by both old and new methods. (Author)

This annotated bibliography enables researchers who are using Raven's Progressive Matrices or the Mill Hill Vocabulary Scales to become familiar with other work that used these tests. The bibliography derives from Raven's own collection of sources, updated to the end of 1971. The major division of material is by tests rather than subject areas;…

A reanalysis of Shaycroft's matrix of intercorrelations of 10 test variables plus 4 random variables is discussed. Three different procedures were used in the reanalysis: (1) Image Component Analysis, (2) Uniqueness Rescaling Factor Analysis, and (3) Alpha Factor Analysis. The results of these analyses are presented in tables. It is concluded from…

Monte Carlo procedures are used to develop stress distributions using Kruskal's second stress formula. These distributions can be used in multidimensional scaling procedures to determine whether a set of data has other than random structure. (Author/JKS)
