Patients with mild Alzheimer's disease (AD) display a greater tendency to endorse unstudied items as "old" on memory tests than healthy older adults. This liberal response bias may result in mistaken beliefs about the completion of common tasks. This research attempted to determine whether it was possible to shift the response bias of mild AD…

A multidimensional item response theory model that accounts for response style factors is presented. The model, a multidimensional extension of Bock's nominal response model, is shown to allow for the study and control of response style effects in ordered rating scale data so as to reduce bias in measurement of the intended trait. In the current…

A cross-sectional non-clinical sample of 1,218 adolescents, aged 10-17 years, completed measures of stress, rumination, and depression to allow tests of the response style theory of S. Nolen-Hoeksema [J Res Adolesc 4:519-534, 1994] in adolescents, in particular whether increasing levels of stress and rumination in early adolescence are predictive…

The distinction between automatic processes and controlled processes is a central organizational theme across areas of psychology. However, this dichotomy conceals important differences among qualitatively different processes that independently contribute to ongoing behavior. The Quadruple process model is a multinomial model that provides…

In this paper I present a class of discrete choice models for ordinal response variables based on a generalization of the stereotype model. The stereotype model can be derived and generalized as a random utility model for ordered alternatives. Random utility models can be specified to account for heteroscedastic and correlated utilities. In the…

The goal of this study is to investigate how features of a rating scale developed for English-speaking populations interact with Spanish-speaking respondents' response styles and functional categories of judgment. A sample of 400 Spanish-speaking students took a translated scale and a scaling task developed to measure response sets and functional…

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…

Glickman, Gray, and Morales (this issue) propose a statistical model for measuring the unobserved latency of stimulus-controlled processes. The model accounts for both speed and accuracy and does so by assuming that participants set an internal deadline. If a stimulus-controlled response is not produced by the deadline, the participant then…

Two experiments were performed to study inductive reasoning as a set of thought processes that operates on the structure, as opposed to the content, of organized memory. The content of the reasoning consisted of inductions concerning the names of mammals, assumed to occupy a Euclidean space of three dimensions (size, ferocity, and humanness) in…

A model is presented that counselors in small groups may use to improve students' test-taking skills and motivation and to enhance students' self-knowledge and decision-making ability through better test interpretation. (Author)

Van Breukelen (this issue) provides an approach to using both response time (RT) and accuracy for (1) measuring latent abilities of participants even when they may trade speed for accuracy, and for (2) providing insight into the psychological processes underlying task performance. In this commentary, I focus on the second of these aims and assess…

This paper describes quantitative tests which show the sophisticated-guessing model to be better than the criterion bias model in its ability to predict the outcome of certain kinds of recognition experiments. (Author/RK)

Investigates the effects of a videotaped model upon children's verbal originality. Among the four experimental groups tested, it was found that the group who viewed the videotaped model had significant increases in both quantity and quality of divergent productions. (Author/DEP)

Longstreth's critique of Jensen's research on the relationship of IQ to individual differences in visual reaction time (RT), measured in the Hick paradigm, is said to have numerous errors of fact and interpretation, some trivial and some of theoretical importance. (Author/LMO)

The stability of a 2-factor model proposed for the Gibb Experimental Test of Testwiseness was studied with 173 undergraduates. Confirmatory factor analysis results indicate that data fit the two-factor model and a simpler one-factor model. The Gibb test could be characterized as tapping a general testwiseness proficiency.
