We investigated for the first time the genetic and environmental aetiology behind scientific achievement in primary school children, with a special focus on possible aetiological differences for boys and girls. For a representative community sample of 2,602 twin pairs assessed at age nine years, scientific achievement in school was rated by…

Developmental dyslexia was investigated within a well-understood and fully specified computational model of reading aloud: the dual route cascaded model (DRC [Coltheart, M., Rastle, K., Perry, C., Langdon, R., & Ziegler, J.C. (2001). DRC: A dual route cascaded model of visual word recognition and reading aloud. Psychological Review, 108,…

International comparisons in educational achievement and economic performance have spurred studies on the East Asian learner. In this context the cultural perspective on the Chinese learner has gained currency. This paper examines how the interaction of cultural, social and structural forces shape the changing patterns of diversity among Chinese…

Higher education settings in the United States typically include several types of writing assessments. Since tests determining students' placement into writing courses are often high-stakes, it is imperative for those who make placement decisions to be knowledgeable of the different types of learners entering higher education in order to make…

This study aimed to evaluate the impact of individual differences in working memory capacity on number transcoding. A recently proposed model, ADAPT (a developmental asemantic procedural transcoding model), accounts for the development of number transcoding from verbal form to Arabic form by two mechanisms: the learning of new production rules…

The literature on participant roles in bullying lacks empirical studies that seek to explain what differentiates defenders from outsiders (or passive bystanders). The present study tested a conceptual model in which two personal characteristics of early adolescent students (empathy and perceived social self-efficacy) were considered as possible…

Three experiments examined the effects of interactive visualizations and spatial abilities on a task requiring participants to infer and draw cross sections of a three-dimensional (3D) object. The experiments manipulated whether participants could interactively control a virtual 3D visualization of the object while performing the task, and…

The purpose of the present study was to explore Dutch spelling development throughout the elementary grades. Two issues were considered (a) dimensional structure over time, and (b) rate of change. Whether the rate of change differs depending on gender, ethnicity, or word reading skill was examined in particular. A pseudolongitudinal dataset with…

We extend prior research on involvement in employee development activity by including prominent individual difference constructs that have been previously ignored in this area of research. These include two important personality characteristics (conscientiousness and openness to experience), mental ability and goal orientation constructs. We…

English is a language, which is spoken by numerous people across the world. It has acquired a prominent place in meeting the communicational needs of the people. Grammar is a set of rules that helps the people to use the language better. In schools, the teachers of English are considered as the most important factor in making the study of English…

This paper examines whether teachers in schools serving students from high-poverty backgrounds are as effective as teachers in schools with more advantaged students. The question is important. Teachers are recognized as the most important school factor affecting student achievement, and the achievement gap between disadvantaged students and their…

This study focuses on the effects of situated learning on students' knowledge acquisition by investigating the influence of individual differences in such learning. Seventy-nine graduates were recruited from an educational department and were assigned to situated learning and traditional learning based on a randomized block design. Results…

This study is the first to examine the latent structure of individual differences reflected in the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1985), a commonly used and well-validated measure designed to assess an adult's current state of mind regarding childhood experiences with caregivers. P. E. Meehl's (1995)…

A psychological construct, such as personality, is an abstraction that is not directly seen but inferred through observed regularities in cognitive, affective, and behavioral responses in various settings. Two assumptions give meaning to the idea of construct validity. First, constructs represent real phenomena that exist apart from the potential…

In 2 experiments, participants completed both an attentional control battery (OSPAN, antisaccade, and Stroop tasks) and a modified semantic priming task. The priming task measured relatedness proportion (RP) effects within subjects, with the color of the prime indicating the probability that the to-be-named target would be related. In Experiment…
