This article provides unbiased estimates of the proportion of items in an item domain that an examinee would answer correctly if every item were attempted, when a closed sequential testing procedure is used. (Author)

Uses principles of latent trait theory to derive conditions under which mean differences between groups on an observed variable are in fact indicative of mean differences on an underlying construct. Pays particular attention to the logistic curve as a model for describing the relation between the observed variable and the construct. (Author/CB)

Various person reliability coefficients, including within- and between-occasion consistency measures, were investigated using the test and retest responses of 123 undergraduates on the Basic Personality Inventory (BPI). Results indicate person reliability may be a multidimensional concept, and that certain item consistency measures are confounded…

Examined the P scale of the Eysenck Personality Questionnaire in three samples of normal Canadian and Japanese students who obtained either very high or very low means on the P scale. Psychometric problems were identified in the sample with a low P mean. Recommended that the scale be renamed. (JAC)

In preparation for a conference on learning and individual differences, the invited authors prepared chapters, which were distributed in draft form. Presentations were followed by discussions, which were recorded, and then edited for this volume, so that the discussion transcript follows each paper. The chapters in part 1, General Background and…

The purpose of this paper is to highlight some psychometric cautions that should be observed when seeking to develop short form versions of tests. Several points are made: (1) score reliability is impacted directly by the characteristics of the sample and testing conditions; (2) sampling error has a direct influence on reliability and factor…

With the rise of violent teenage crime, with an alarming number of child soldiers across the globe, and with the continually increasing number of children and adolescents who are victimized by violence and war, an instrument that measures nonviolent tendencies would be very useful. The Teenage Nonviolence Test (TNT) was recently developed and…

This research study was designed to establish the reliability of the Teenage Nonviolence Test (TNT). The consistency and factor structure of the TNT using a sample of 376 adolescents were evaluated. The stability of the TNT was assessed over time by administering the TNT twice with a two week intervening interval to 87 adolescents. The TNT appears…

This study was designed to document the validity of the Teenage Nonviolence Test (TNT). In this study the concurrent validity of the TNT in various ways, the validity of the TNT using known groups, and the discriminant validity of the TNT by evaluating its relationships with other psychological constructs were assessed. The results showed that the…

The Learning Style Inventory (LSI; Kolb, 1976; 1985 ) is a commonly used measure of learning styles based on Kolbs Experiential Learning Model. The psychometric soundness of LSI scores has been critiqued historically. This study reviewed the literature on the LSI and evaluated the psychometric properties of Kolbs original and revised versions of…

The post-World War II rehabilitation of large numbers of psychologically deprived and socially maladjusted teenaged war orphans and/or concentration camp victims in Israel was carried out within normal group structures. (Author)

This paper is devoted to the study of a certain statistic, u, defined on samples from a bivariate population with two variances and correlation p. (Author)

Article is a response to the contention that the inhibition associated with S is nonmonotonic with respect to non-reinforced trails. (Author)
