Examines the relation between social and academic competence of school-age children (N=163) to determine the direction of influence between these two domains across time. Results supported a reciprocal model, indicating that academic achievement directly influenced social competence, and social competence was reciprocally related to academic…

Down syndrome is associated with severe deficits in language and verbal short-term memory, but the causal relationship between these deficits is unclear. The current study therefore investigated the influence of language abilities on verbal short-term memory performance in Down syndrome. Twenty-one individuals with Down syndrome and 29 younger…

The Graduate Record Examination General Test (GRE) is a measure of academic reasoning abilities that is intended to be a power test in which speed of responding plays at most a minor role. To test this assumption, we experimentally administered both the verbal and quantitative sections of the GRE with standard time limits and with 1.5 times the…

Historically, mathematics has been stereotyped as a male domain, and there is considerable evidence to support this belief. In the last 30 years, mathematics education researchers have uncovered a range of factors contributing to the documented achievement and participation differences that favored males and sought to redress them. Mathematics as…

A number of theories of second language L2 acquisition acknowledge a role for explicit L2 knowledge. However, the testing of these theories remains problematic because of the lack of a widely accepted means for measuring L2 explicit knowledge. This article seeks to address this lacuna by examining L2 explicit knowledge from two perspectives.…

Within the last few decades, there have been multidimensional advancements in language assessment. Some of the advancements have been in the direction of developing theoretical models of the construct of language ability, others in the line of measuring that construct, and still some others toward materializing the outcomes of measuring the…

People spontaneously discover new representations during problem solving. Discovery of a mathematical representation is of special interest, because it shows that the underlying structure of the problem has been extracted. In the current study, participants solved gear-system problems as part of a game. Although none of the participants initially…

This study investigated ability-related differences in strategy use and development in the domain of simple arithmetic, in terms of the model of strategic change, using the choice/no-choice method and the chronological-age/ability-level-match design. Twenty-six second-graders with strong mathematical abilities (MA), 25 second-graders with weak MA,…

One-hundred seventy-five students enrolled in either a traditional classroom lecture section of General Psychology or in an online section of the same course were compared on exam performance. When covariates of high school grade point average and SAT composite scores were entered into the analysis, students enrolled in the classroom based lecture…

Using a lexical-decision task performed by Dutch-English bilinguals, the author showed that the recognition of visually presented first language (L1; e.g., touw) and second language (L2; e.g., back) targets is facilitated by L2 and L1 masked primes, respectively, which are pseudohomophones (roap and ruch) of the target's translation equivalent…

Can music in and of itself tell anything about the mind of the person who composes or performs it? This question is of general philosophical interest, but it takes on more than philosophical significance in contexts where there is reason to think that music may be the only significant point of contact between one human being and another. There are…

This study of 4-year-old twins investigated the genetic and environmental origins of comorbidity between language impairment and nonverbal ability by testing the extent to which language impairment in one twin predicted nonverbal ability in the co-twin. Impairment of language ability was defined as scores below the 15th percentile on a general…

Putting prospective teachers through standardized interviews regarding their approach to the job might fulfill a sorting function, but it can prove to be time-consuming on both sides. Online applications, though they can be relatively quick and easy, tend to give a school district too little information about the real-world potential of…

Placement tests are rapidly joining the ranks of high-stakes testing and college freshmen are required to take mathematics placement exams to determine their first mathematics course upon entering college. Unfortunately, these exams tend to place students in a lower-level or remedial course. As a result, additional expenses are incurred, degree…

Giftedness researchers have long debated whether there is empirical evidence to support a distinction between giftedness and attained level of achievement. In this paper we propose a general theoretical framework that establishes scientific criteria for acceptable evidence of superior reproducible performance, which any theory of exceptional…
