Prospective memory (PM), the ability to remember to execute an intention in the future, is critical for the performance of everyday tasks important for independence and quality of life. PM failures are associated with negative health, financial, and social outcomes, and are more frequent with increased age and can be even greater for older adults…

A robust finding in cognitive psychology is that training children's spatial abilities is an effective route to improving mathematics performance. Despite this finding, there is limited representation of spatial reasoning in school curricula. To bridge this gap between research and practice, we created the Spatial Reasoning Toolkit (SRT; Gifford…

This study explores the relationship between collaborative dynamics, expressed through observed leadership behaviour, and skills. It is based on the mechanical design activity of six dyads of students (post-secondary vocational training), composed of 11 boys and one girl, who are improving an existing mechanical system. Actions are studied using…

Recent developments in Augmented Reality (AR) headset technologies have allowed for users to see and manipulate the same 3D hologram at the same time, allowing for collaborative, embodied interactions using gestures and actions. Three-dimensional geometry has traditionally been taught largely through 2D projections of 3D figures on pages or…

The rising prevalence of autism spectrum disorder (ASD) necessitates a greater understanding of the academic experience of diagnosed children. The present study investigates several predictors of teacher-reported academic competence among a sample of elementary school children. All children in the sample were referred for an ASD evaluation and…

Much recent research has focused on the relation between spatial skills and mathematical skills, which has resulted in widely reported links between these two skill sets. However, the magnitude of this relation is unclear. Furthermore, it is of interest whether this relation differs in size based on key demographic variables, such as gender and…

One critical objective of high-quality education is to provide citizens literate in science, technology, engineering, and math (STEM) to ensure economic success (as reported by Newcombe (Harnessing spatial thinking to support STEM learning (OECD Education Working Papers, No. 161), OECD Publishing, Paris, 2017). Many studies have found a…

When students receive the same score on a test, does that mean they know the same amount about the topic? The answer to this question is more complex than it may first appear. This paper compares classical and modern test theories in terms of how they estimate student ability. Crucial distinctions between the aims of Rasch Measurement and IRT are…

Socio-emotional abilities have been proposed as an extension to models of intelligence, but earlier measurement approaches have either not fulfilled criteria of ability measurement or have covered only predominantly receptive abilities. We argue that faking ability--the ability to adjust responses on questionnaires to present oneself in a desired…

Theory of Mind (ToM) is the ability understand that other people's mental states may be different from one's own. Psychometric models have shown that individual differences in ToM can largely be attributed to general intelligence ("g") (Coyle et al. 2018). Most psychometric models specify "g" as a reflective latent variable,…

The development of human abilities stems from a complex interplay between genetic predispositions and environmental factors. Numerous studies have compared musicians with non-musicians on measures of musical and non-musical ability, frequently attributing musicians' superior performance to their training. By ignoring preexisting differences,…

Subscore added value analyses assume invariance across test taking populations; however, this assumption may be untenable in practice as differential subdomain relationships may be present among subgroups. The purpose of this simulation study was to understand the conditions associated with subscore added value noninvariance when manipulating: (1)…

The propensity to use a spatial framework to organize other pieces of information is a widespread phenomenon that permeates humans' representation of diverse concepts, including numerical quantities. Developmental studies on numerical cognition have revealed that humans possess a system for abstract quantity representation that is functional at…

Classic studies in cognition have demonstrated that the use of appropriate memory mnemonics can reliably increase recall performance. However, is the facilitative effect of mnemonics consistent across all individuals? As some mnemonics explicitly contain a large visuospatial component, does normal variance in visuospatial aptitudes predict the…

This study investigated the direct and indirect roles of verbal and visuospatial memory in Chinese reading comprehension. One hundred twenty-eight Cantonese-speaking children participated in the study at the end of their 3rd year of kindergarten in Hong Kong. Both verbal and visuospatial memory were found to be significantly associated with…
