Cross-sectional and incremental age effects on cognitive processes that underlie individual differences in components of working memory (WM; phonological loop, visual-spatial sketchpad, executive processing) and mathematical problem-solving accuracy were examined in elementary school children. A battery of tests was administered that assessed…

In hypertext learning, comparative research is mostly dedicated to differences in text-hypertext information retrieval and processing and to optimization of nonlinear information retrieval. Most of these investigations are conducted within the context of applied research. The theoretical background of information acquisition from linear and…

Results of longitudinal studies suggest that the stability of preferences varies across individuals, although it is unclear what variables account for these differences. We extended this work by conducting periodic assessments of preference for leisure activities over 3 to 6 months with 10 adults with developmental disabilities. Although previous…

This article describes the response of 483 teacher trainees when asked their motivation for undertaking teacher training. There was no predetermined agenda, and the open responses were analysed into six distinct categories covering 93 per cent of responses. These included career-related reasons such as wanting a rewarding and challenging career or…

Metacognition is an important construct for the understanding of mental retardation and the design of educational treatment for this population. However, assessment procedures used for the testing of metacognition do not seem appropriate for these subjects. This article presents an interactive assessment procedure that uses a game-like task.…

Although educational leaders may be optimistic about initiating change, lasting reforms are rare. The group polarization literature, although dated, provides an important explanation for a very current problem. The theory holds that when there are differences of opinion to begin with, a counter-conformity effect works among members of groups.…

This paper is the first to systematically document the relationship between individual teacher performance incentives and student achievement using United States data. We combine data from the National Education Longitudinal Survey on schools, students, and their families with our own survey conducted in 2000 regarding the use of teacher…

Background: The aim of the present study was twofold: 1) to determine whether phonological skills measured in deaf prereaders predict their later phonological and reading skills after one year of reading instruction as is the case for hearing children; 2) to examine whether the age of exposure to a fully specified phonological input such as Cued…

Little is known about the effects of social context or "place" factors (e.g., characteristics of local populations) on African Americans' perceptions and experiences of racism. Using data from 42,445 U.S. black women collected during the 1997 follow-up wave of the Black Women's Health Study, we investigated the association between neighborhood…

This study analyzed the production of voice onset time (VOT) for /p, t, k/ in Japanese and English by English-speaking children (n = 15) in a Japanese immersion program. The immersion children produced Japanese voiceless stops with significantly longer VOT values than the monolingual Japanese children and the immersion teachers, but they produced…

This study represents further work into the area of what specific processes determine whether a sibling relationship will be positive or negative. Specifically addressed was the influence of each child's personality or temperament in shaping the quality and type of sibling relationship. Significant attention was paid to analyzing sibling…

Games have long been used as instructional tools, but actual research examining that concept has been sparse. Increased sophistication and lower cost in hardware and software for personal computers has created a budding movement to incorporate computer games into learning environments. This paper discusses criteria for selecting an instructional…

This study sought to examine why peer interaction can facilitate learning, with the hypothesis that collaborative learning provides a social context that is conducive to the generating of explanations (an activity positively associated with learning). Individualistic and collaborative learning contexts were compared for 96 college students (19…

With few exceptions, the development of adult intelligence assessment instruments has proceeded along the lines of the Binet-Simon tests for children, stressing psychological assessment over the evaluation of what an individual knows. These tests, developed over 90 years ago, were quite effective in predicting school success, but were much less…

The consciousness of dizygotic twins in their communication of actions and events as seen in the visual cliff pictures published by E. J. Gibson and R. D. Walk (1960) was studied in Sweden. In the process of communication, many different state spaces are generated. The methodology demonstrates that ecological and biophysical properties of language…
