The worst performance rule (WPR) describes the phenomenon that individuals' slowest responses in a task are often more predictive of their intelligence than their fastest or average responses. To explain this phenomenon, it was previously suggested that occasional lapses of attention during task completion might be associated with particularly…

Few individuals--whether scholars or laypersons--think that the words "smart" or "intelligent" suffice to characterize a person's intellectual strengths. In this article, the author reviews a set of terms commonly used to characterize intellectual strengths and then introduces the concept of "synthesizing"--an…

Recent studies in psychology emphasize the pivotal roles of adopting a growth mindset to enhance students' motivation and employing effective memory strategies to improve memory performance. This study evaluated the impact of a metacognitive intervention that combined the promotion of a growth mindset with the teaching of efficient learning…

Many areas of psychology assume that performance on tasks of interest is stable through time. Here, using time-sensitive modeling of working memory task performance, we show not only was this assumption incorrect, but that certain components of the performance trajectory (e.g., final task performance; rate of change) were independently predictive…

Collective intelligence (CI) is said to manifest in a group's domain general mental ability. It can be measured across a battery of group IQ tests and statistically reduced to a latent factor called the "c-factor." Advocates have found the c-factor predicts group performance better than individual IQ. We test this claim by meta-analyzing…

The expert performance theory by Ericsson et al. which maintains that deliberate practice can account for most of the variance in expertise studies is often posed as a strong scientific framework for research on giftedness. The current study explored relationships between performance, deliberate practice and mindset beliefs about intelligence and…

There are national differences in scientific activity that are not well accounted for by economic and intellectual factors alone. We examine the novel hypothesis that androgen levels may also play a role. Androgens are often referred to as male hormones, but are present in both men and women, and have been linked to performance in other domains,…

We review the musical conservatory as a model for educators to learn how to enhance admissions, instruction, and assessment in liberal arts collegiate settings. Although conservatories serve primarily students wishing to enter musical careers of various kinds, the model on which they are based can, in many ways, serve any student and any school.…

Manipulative artefacts are considered useful scaffolds of arithmetic during early years education, but their use is considered less important as children get older. Yet adult arithmetic performance often recruits artefacts to improve accuracy and efficiency, and so the same benefits should accrue to children beyond early years. We propose that…

This article considers how professional knowledge should be assessed. It is maintained that the assessment of professional know-how raises distinctive issues from the assessment of know-how more generally. Intellectualist arguments which suggest that someone's giving an account of how to "F" should suffice for attributing to them…

This article describes the themes found in the past 25 years of creativity research. Computational methods and network analysis were used to map keyword theme development across ~1,400 documents and ~5,000 unique keywords from 1990 (the first year keywords are available in Web of Science) to 2015. Data were retrieved from Web of Science using the…

Although algebra is a prerequisite for higher mathematics, few studies have examined the mathematical and cognitive capabilities that contribute to the development of algebra word problems solving skills. We examined changes in these relations from second to ninth grades. Using a cross-sequential design that spanned 4 years, children from 3…

A meta-analysis was performed to examine differences in IQ profiles between individuals with Asperger's disorder (AspD) and high-functioning autism (HFA). Fifty-two studies were included for this study. The results showed that (a) individuals with AspD had significantly higher full-scale IQ, verbal IQ (VIQ), and performance IQ (PIQ) than did…

Match-to-sample is a timed task in which a subject is presented with a visual stimulus (the probe) and must select a match to that stimulus (the target) from among an array of distractors. These tasks are frequently employed as tests of basic cognitive abilities and demonstrate consistent correlations with measures of intelligence. In the current…

Physical education has long suffered low status within educational institutions, due to the assumption that practical knowledge or 'knowing how' is somehow set apart from cognitive development and anti-intellectual. This dualistic conception of mind and body is challenged using Ryle's conceptual account of 'intelligent…
