The present study investigated the functioning of three psychometric models for cognitive diagnosis--the general diagnostic model, the fusion model, and latent class analysis--when applied to large-scale English as a second language listening and reading comprehension assessments. Data used in this study were scored item responses and incidence…

Models of a psychological process can be difficult to discriminate experimentally because it is not easy to determine the values of the critical design variables (e.g., presentation schedule, stimulus structure) that will be most informative in differentiating them. Recent developments in sampling-based search methods in statistics make it…

Background: Immersive virtual worlds are one of a range of different platforms that can be grouped under the concept of mediated environments, i.e. environments that create a metaphorical space in which participants can position themselves and be embodied. Synthesising the literatures concerning the various mediated environment technologies…

Examines ritual from theoretical, clinical, and practical perspectives. Discusses symbolic cognition and its relation to myth and ritual. Abstracts a typology of ritual from phenomenological sources. Gives examples of liberation, transformation, and celebration rituals. Identifies elements commonly employed in ritual activity as guides to ritual…

Defines a sampling taxonomy that shows the differences between and relationships among the bootstrap, the jackknife, and the randomization test. Demonstrates the usefulness of the taxonomy for teaching the goals and purposes of resampling schemes and presents univariate and multivariate examples. (SLD)

One important goal of Swedish educational policies is to integrate all pupils within regular education, irrespective of disability or difficulties in school, and to adjust education to individual needs. The aim of this paper was to explore how schools "socially construct", i.e. identify and support, pupils with special educational needs.…

This paper introduces the mixture general diagnostic model (MGDM), an extension of the general diagnostic model (GDM). The MGDM extension allows one to estimate diagnostic models for multiple known populations as well as discrete unknown, or not directly observed mixtures of populations. The GDM is based on developments that integrate located…

Systematic Treatment Selection (STS) is a form of technical eclectism that develops and plans treatments using empirically founded principles of psychotherapy. It is a model that provides systematic guidelines for the utilization of different psychotherapeutic strategies based on patient qualities and problem characteristics. Historically, it…

The ambiguity disadvantage (slower processing of ambiguous words relative to unambiguous words) has been taken as evidence for a distributed semantic representational system like that embodied in parallel distributed processing (PDP) models. In the present study, we investigated whether semantic ambiguity slows meaning activation, as PDP models…

The educational achievement and attainment of young people in the United States has been a long-standing issue of concern. While analyses of long-term trend data from the National Assessment of Educational Progress (NAEP) show that students in the United States have made gains in reading and mathematics over the past few decades, a sizeable…

This study describes data collected from undergraduate chemistry majors, high school chemistry teachers, and chemistry faculty in an effort to better understand how models and conceptions of scientific inquiry might change through time and experience as the teachers' views move toward those more universally held by practicing scientists. (Contains…

Three studies examined the development of category-based induction using an induction then recognition (ITR) procedure in which participants make category-based predictions about study items and are then given a surprise recognition test that requires discrimination between old and new category members. Exposure duration for study items was either…

As with any test administered across linguistically and culturally diverse groups, evidence suggesting the equivalence of score meaning across countries is needed for valid comparisons. The current study examines the cross-cultural equivalence of score interpretations from the Trends in International Mathematics and Science Study (TIMSS)-1999 from…

The importance of effective healthcare communication between healthcare providers and people needing healthcare is well established. People with communication disabilities are at risk of not being able to communicate effectively with their healthcare providers and this might directly compromise their health, healthcare and their right to…

The remarkable successes of the physical sciences have been built on highly general quantitative laws, which serve as the basis for understanding an enormous variety of specific physical systems. How far is it possible to construct universal principles in the cognitive sciences, in terms of which specific aspects of perception, memory, or decision…
