This article reports the findings of a 3 year research project which investigated disciplinary variation in student writing. Within an Open University course in the history of science, students from an arts background were found to achieve significantly higher grades than those from a science background. Textual and interview data suggest that…

Elementary school children, some of whom were nonnative speakers of English, learned to add and subtract integers in a discovery-based multimedia game either with or without verbal guidance in English or optionally in Spanish (Groups G--verbal guidance and No-G--no verbal guidance, respectively). Group G members chose to listen to verbal…

To what extent does the wording and syntactic form of people's writing reflect their personalities? Using a bottom-up stratified corpus comparison, rather than the top-down content analysis techniques that have been used before, we examine a corpus of e-mail messages elicited from individuals of known personality, as measured by the Eysenck…

Research suggests that children with specific language impairment (SLI) have processing limitations; however, the mechanisms involved have not been well defined or investigated in a theory-guided manner. The theory of constructive operators was used as a framework to explore processes underlying limited processing capacity in children with SLI.…

Four components of a comprehensive, responsive parenting style ("Responsiveness to Signals, Maintaining Attentional Focus, Rich Language, and Warmth") have been previously identified [Landry, S. H., Smith, K. E., & Swank, P. R. (in press). Responsive parenting: Establishing early foundations for social, communication and independent problem…

Cluster analytic methods were used to create 4 theorized ethnic identity statuses (achieved, foreclosed, moratorium, and diffused) among 940 African American adolescents (13-17 years old), college students (18-23 years old), and adults (27-78 years old). Evidence for the existence of 4 identity statuses was found across the 3 age groups. The…

Stuttering has been considered a heritable disorder since the 1930s. There have been different models of transmission that have been proposed most involving a polygenic component with or without a major locus. In spite of these models, the characteristics being transmitted are not known. This study used two different tasks--a tapping task that is…

The term "gifted" implies a permanent superiority. However, the majority of children who score in the top few percentiles on ability and achievement tests in 1 grade do not retain their status for more than a year or 2. The tendency of those with high scores on one occasion to obtain somewhat lower scores on a later occasion is one…

We consider human performance on an optimal stopping problem where people are presented with a list of numbers independently chosen from a uniform distribution. People are told how many numbers are in the list, and how they were chosen. People are then shown the numbers one at a time, and are instructed to choose the maximum, subject to the…

How do singers approach teaching and learning in the context of performance studies in higher education? And how is their approach distinct from that taken by instrumentalists in the same context? This paper focuses largely on verbal dialogue recorded in 67 instrumental and vocal lessons, in the music department of a UK university. It examines the…

Regardless of individual differences at kindergarten entry, schools have a mission to promote reading achievement for all students. Within-class ability grouping is an instructional strategy that has received attention for its potential benefits to students. The authors assessed the effects of within-class ability grouping on kindergarten reading…

Children's social networks often include close family members, extended family members, and friends, but little is known about interindividual differences in the patterning of support from these sources. In this study, we used person-oriented analyses to differentiate patterns of support for children undergoing the transition to adolescence.…

In a short-term longitudinal study of 432 first-grade children, we examined whether gender interacted with contextual differences (school-level poverty) and individual differences at school entry (behavioral problems, emotional problems, and social competence) to predict changes in peer physical and relational victimization and receipt of…

Individual differences in temperament and personality influence children's development of self-regulation, social relationships, and adaptation within varied contexts. For young children with disabilities and/or family poverty, early school experiences provide both significant challenges and opportunities. In this study, teachers rated the…

This study investigated correlates of domain-general and domain-specific components of creativity. 158 college students completed a questionnaire that assessed their motivational and personality traits (i.e., intrinsic and extrinsic motivation, creative personality, and originality in word association) as well as intellectual abilities (SAT verbal…
