This research investigates the influence of color-filtered lighting in relation to biophilic design, specifically within the preschool learning environment where design elements impact early childhood development. Among various architectural design components, research underscores the pivotal role of lighting in affecting children's pleasantness…

Anxiety in Children can develop into pervasive disorders in adulthood if not treated. Research shows dysfunctional Executive Function (EF) and anxiety are both shown to have a negative impact on math achievement in children and adolescents (Trezise & Reeve, 2018; Kalaycioglu, 2015; Owens, Stevenson, Hadwin & Norgate, 2012). Chung, Weyandt,…

Previous research on 4-6-year-olds' interpretations of adjunct control has observed non-adult-like behavior for sentences like "John called Mary before running to the store." Several studies have aimed to identify a grammatical source of children's errors. This study tests the predictions of grammatical and extragrammatical accounts by…

Numerous studies suggest that by elementary school, children have implicit and explicit gender stereotypes about the toys, activities, roles, and abilities associated with boys vs. girls. Furthermore, these stereotypes have been shown to affect children's goals and behaviors, leading them to pursue activities that are associated with their own…

Thirty to 80% of children with autism spectrum disorder also have symptoms of attention-deficit hyperactivity disorder. Many children with autism spectrum disorder and attention-deficit hyperactivity disorder experience difficulties carrying out goal-directed behaviors, particularly when it comes to inhibiting responses. The aim of this study was…

Inhibitory control has been widely studied in association with social and academic adjustment. However, prior studies have generally overlooked the potential heterotypic continuity of inhibitory control and how this could affect assessment and understanding of its development. In the present study, we systematically considered heterotypic…

The Dimensional Change Card Sort (DCCS) task is a widely used measure of preschoolers' executive function. We combined data for 3,290 3-year-olds from 37 unique studies reporting 130 experimental conditions. Using raw pass/fail counts, we computed the pass rates and chi-squared value for each against chance (50/50) performance. We grouped data…

Purpose: This study compared attention control and flexibility in school-age children who stutter (CWS) and children who do not stutter (CWNS) based on their performance on a behavioral task and parent report. We used a classic attention-shifting paradigm that included manipulations of task goals and timing to test effects of varying demands for…

Understanding the role of negative emotionality in the development of executive functioning (EF) and language skills can help identify developmental windows that may provide promising opportunities for intervention. In addition, because EF and language skills are, in part, genetically influenced, intergenerational transmission patterns are…

Widening achievement gaps between homeless and highly mobile (HHM) youth and their peers highlight the need for research to understand effects of risk and adversity on development to promote resilience and positive adaptation. Youth living under the poverty line experience more risk and adversity, leading to difficulty in multiple domains…

Adults with autism spectrum disorders (ASD) have shown deficits in switching between rules governing their behaviour, as have high-functioning children with ASD. However, there are few studies of flexibility in lower-functioning children with ASD. The current study investigated this phenomenon with a group of low-functioning children with ASD…

Developmental intergroup theory would predict that children develop fewer or weaker stereotypes about toys that have less distinguishable gender attributes than those that are clearly associated with a gender. The purpose of this study was to investigate the role of neutral and ambiguous toys in 31 three- to five-year-old children's play behaviour…

Basic research with pigeons on behavioral momentum suggests that differential reinforcement of alternative behavior (DRA) can increase the resistance of target behavior to change. This finding suggests that clinical applications of DRA may inadvertently increase the persistence of target behavior even as it decreases its frequency. We conducted…

Over the past 30 years researchers have learned a great deal about the development of object processing in infancy. In contrast, little is understood about the neural mechanisms that underlie this capacity, in large part because there are few techniques available to measure brain functioning in human infants. The present research examined the…

In this study, we investigated the relationships between rapid naming of letters, digits and colours, and reading ability and executive function. We gave fifty-six grade three and four children rapid automatised naming tasks using letters and digits as stimuli, executive function measures including the Stroop task, a working memory task and the…
