We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day.…

Theories of working memory often disagree on the relationships between processing and storage, particularly on how heavily they rely on an attention-based limited resource. Some posit separation and specialization of resources resulting in minimal interference to memory when completing an ongoing processing task, while others argue for a greater…

Sequences of auditory objects such as one-syllable words or brief sounds disrupt serial recall of visually presented targets even when the auditory objects are completely irrelevant for the task at hand. The "token set size effect" is a label for the claim that disruption increases only when moving from a 1-token distractor sequence…

Bilingual children exhibit enhanced working memory (WM) skill relative to monolingual children, which could have implications for early mathematics development. Competency in mathematics is supported by conceptual and procedural mathematical knowledge, and numerical knowledge is in turn supported by underlying cognitive processes such as WM.…

Autism spectrum disorder is characterized by difficulties with social communication, with a preponderance in males. Evidence supports a relationship between metacognitive executive functions (e.g. planning, working memory) and social communication in autism spectrum disorder, yet relationships with specific metacognitive executive functions and…

The present study analyzed the relationship between domain-general abilities and fraction knowledge in fifth grade, and investigated the mediating role of division competence in that relationship. Children (n = 175) were assessed in fourth grade on domain-general abilities (selective attention, working memory, fluid intelligence) and on division…

Purpose: The purpose of this study was to delineate differences between children with specific language impairment (SLI), typical age-matched (TAM) children, and typical younger (TY) children in learning and mastering an undisclosed artificial morphological rule (AMR) through exposure and usage. Method: Twenty-six participants (eight 10-year-old…

Prospective memory (PM) performance suffers when individuals collaborate, consistent with findings of "collaborative inhibition" in episodic recall. However, prior research indicates strong individual differences, such that some collaborative groups are more effective than others. To identify successful and unsuccessful collaborative…

L1 and L2 writers attend to different aspects of the formulation subprocess of writing. L2 writers devote more time and attention to low-level aspects such as grammar correction and spelling (Barbier 1998; Fagan and Hayden 1988; Whalen and Ménard 1995), leading to better spelling performances than L1 writers (Gunnarsson-Largy 2013). In…

The present study aimed at developing a second language pragmatic aptitude test. To do so, the relevant literature was consulted, different components contributing to pragmatics aptitude were identified and tabulated and test items were developed for each component. The outcome was a test comprising four sections, i.e. memory for pragmatic rule…

Purpose: The purpose of the current study was to investigate the relationship between orthographic learning and language, reading, and cognitive skills in 9-year-old children who are deaf or hard of hearing (DHH) and to compare their performance to age-matched typically hearing (TH) controls. Method: Eighteen children diagnosed with…

In accord with classic schema theory, people are susceptible to forming false memories that align with stored schema representations (Brewer & Treyens, 1981). Furthermore, clinicians schematize mental disorders as causal networks of features (de Kwaadsteniet, Hagmayer, Krol, & Witteman, 2010; Kim & Ahn, 2002). We asked whether one…

The Adult Reading History Questionnaire (ARHQ; Lefly & Pennington, 2000) is a widely used measure of self-reported reading difficulties. We explored the factor structure underlying this questionnaire using both exploratory and confirmatory factor analysis. A six-factor solution emerged, with childhood reading ability, current reading attitude,…

Based on cognitive load theory, this paper reports on two experiments investigating the variability effect that occurs when learners' exposure to highly variable tasks results in superior test performance. It was hypothesised that the effect was more likely to occur using high rather than low levels of guidance and testing more knowledgeable than…

Although many interventions have generated immediate positive effects on mathematics achievement, these effects often diminish over time, leading to the important question of what causes fadeout and persistence of intervention effects. This study investigates how children's forgetting contributes to fadeout and how transfer contributes to the…
