Identity formation is a key developmental task in adolescence. Although many adolescents in modern societies face issues of identity, there are substantial individual differences in identity exploration and commitment. Little is known about the origins of these individual differences. The current study investigated the genetic and environmental…

Cook argued that the learning of a new language leads to a state of multi-competence, with the learner's mind changing in ways that go beyond the linguistic realm. The present study follows Dewaele's suggestion that multilingualism is linked to both cognitive and psychological changes. It explores one particular under-researched relationship,…

This study conducted comparative assessment of friendship in preschoolers with high-functioning autism spectrum disorder (HFASD, n = 29) versus preschoolers with typical development (n = 30), focusing on interactions with friends versus acquaintances. Groups were matched on SES, verbal/nonverbal MA, IQ, and CA. Multidimensional assessments…

Utilizing latent transition analysis and multidimensional scaling growth analysis, the authors studied the emerging developmental trajectories in word literacy (i.e., word-reading competence) of a group of 1,503 kindergarteners. Specifically, 3 hypotheses with respect to growth patterns in word literacy from kindergarten to Grade 2 were examined:…

This paper explores students' conceptions of good teaching in three different disciplines. Moreover, the aim is to explore the relation between these conceptions and students' approaches to learning by combining qualitative and quantitative methods. A total of 695 students from the Faculties of Behavioural Sciences, Law and Veterinary Medicine…

The kinds of individual differences in perceptions permitted by the weighted euclidean model for multidimensional scaling are more restrictive than those allowed by models developed by Tucker or Carroll. It is shown how problems which occur when using the more general models can be removed. (Author/JKS)

A family of models for the representation and assessment of individual differences for multivariate data called PINDIS (Procrustean Individual Differences Scaling) is presented. PINDIS sheds new light on the interpretability and applicability of a variety of multidimensional scaling models. (Author/JKS)

A numerical taxonomy of evaluation theory and practice is presented, based on responses by 14 leading evaluators to a two-page questionnaire. A multidimensional scaling analysis of results indicated that differences between evaluation theories are more complex and more divisive than are differences in evaluation practice. (TJH)

Demonstrated a set of research techniques that combine multidimensional scaling, a quantitative cognitive procedure, and a cost-outcome analysis to study subgroup behavior of obsessive-compulsives (N=12). Results indicated that obsessive-compulsives are underinclusive in their evaluation of stimuli during judgment task. (LLL)

The degree to which Procrustean Individual Differences Scaling can be extended to related topics such as target analysis is discussed and a Monte Carlo study investigating the fit of the model under various conditions is presented. (JKS)

Investigated dimensions along which self-analytic group sessions vary. Identified three common dimensions: evaluation, potency, and activity. Used dimensions to describe phases of group development and individual differences in the perception of group sessions. (RC)

One of the most neglected aspects of group counseling and group psychotherapy research involves an investigation of the nature and development of the group members' interpersonal perceptions during the life of the group. In this study, an individual differences multidimensional scaling (INDSCAL) approach was used to study this question. (Author)

Twenty-five HIV-negative late adolescents (13 women and 12 men) who had lost a parent to AIDS generated vignettes in which the characters were deciding whether to use a condom (condom scripts). Two clinically trained judges rated the interpersonal tone of the condom scripts on 17 semantic differential scales. Three other clinically trained raters…

Subjects scaled 48 positive and 32 negative assertion vignettes according to similarity of difficulty to determine how people cognitively present complex social situations. Analyses indicated each dimension could be described according to major component(s) that contributed to it and dimensions varied in importance as a function of assertion…

Multicultural research has traditionally involved normative methodology and definitions of individual differences. To further our understanding of multicultural concerns, the authors urge researchers to broaden the repertoire of methods used in these inquiries. First, the authors highlight the differences among normative, idiographic, and…
