High level reading comprehension is a process that results in a reader's semantic interpretation of a text, or mental model of that text, referred to as the "reader's situation model." Individual differences in readers' verbal working memory resources, as measured by reading span tasks (RST), and operation span tasks (OST), have shown to…

Research Findings: Marginal food security is less studied relative to food insecurity but may also have adverse effects on family outcomes. The present study examined whether parental stress mediated the relationship between marginal food security (MFS) and preschool-aged children's observed self-regulation at three early education centers located…

Reading comprehension ability relies heavily on executive function skills which can be improved with selective interventions. Cognitively engaging physical activity promotes executive function acquisition and may be helpful to improving reading ability. However, unfamiliar and potentially stressful interventions may be counterproductive to these…

This dissertation study aimed to explore whether and how individual differences in verbal and visuospatial working memory capacity and executive functions influence elementary students' mathematics fact mastery and mathematics anxiety as they engage in learning using ReflexTM, a game-based, visuospatial rich adaptive learning platform for…

Longitudinal growth modeling was utilized to examine adaptive behavior over eight years across the three time points (i.e., ages 2-10). Seventy-six parents completed the Vineland Adaptive Behavior Scales interviews of adaptive behavior. Child participants completed standardized developmental testing and an executive function task in toddlerhood…

Background: Verbal fluency tasks are included in a broad range of aphasia assessments. It is well documented that people with aphasia (PWA) produce fewer items in these tasks. Successful performance on verbal fluency relies on the integrity of both linguistic and executive control abilities. It remains unclear if limited output in aphasia is…

Background: Executive function (EF) plays a critical role in academic outcomes in typically developing children, but the contribution of EF to academic performance in Down syndrome (DS) is less well understood. This study evaluated differences in early academic foundations between primary school aged children with DS and non-verbal mental-age…

Purpose: The purpose of this study was to evaluate whether preschoolers with primary language impairment (PLI) show deficits in executive function (EF) compared with their peers with typical development (TD) when inhibition, updating, and mental-set shifting are examined using both linguistically based and visually based tasks. Method: Twenty-two…

In South Africa, many learners with autism spectrum disorder (ASD) attend mainstream and private schools. This study explores the influence of executive function (EF) challenges experienced by one learner with ASD on his behavioural adaptation in an inclusive school environment. An interpretive case study approach was followed to help understand…

This study investigated the extent to which individual differences in working memory (WM) mediate the effects of captions with or without textual enhancement on attentional allocation and L2 grammatical development, and whether L2 development is influenced by WM memory in the absence of captions. We employed a pretest-posttest-delayed posttest…

Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

We investigated whether preschoolers' social-emotional competencies predict their peer relationships and academic achievements during grade one. Measures of cool and hot executive functions, theory of mind, social-problem-solving, and peer acceptance were administered to a sample of 48 preschoolers (M = 77.91 months). Academic achievement and peer…

A growing number of autistic students enter the school system, many with the capabilities of doing grade-level work. For these students, there seems to be a lack of focus on executive functioning, self-regulation, daily living skills (DLS), and self-determination. The Independence Curriculum (IC) is a set of units addressing identified areas of…

Objectives: The aim of the study is to distinguish between perceptuomotor and cognitive inflexibility as the source of set-switching difficulties in children with autism spectrum disorder (ASD). Methods: Seventeen adolescents with ASD and 17 neurotypical controls were presented with a computerized sequencing game using colored shapes. The sequence…

This study investigated the construct of paired associate learning (PAL) and its associations with Chinese word writing in kindergarten children. A total of 188 Chinese children (95 boys, mean age = 5.65 years; SD = 0.34) from [Xi'an], Mainland China in the third year of kindergarten participated in this study. Children were assessed on measures…
