Educators are required to use evidence-based practices to support student development of academic skills. Results from single-case experimental designs are well suited for this purpose and may be more flexible for applied use than group-based designs. However, educators also require information about which interventions work for whom and under…

Results from single-case experimental designs are well suited for this purpose and may be more flexible for applied use than group-based designs.

This study aimed to investigate the extent to which WM measured in kindergarten predicts WM measured in second grade (stability of individual WM progress) and the extent to which WM measured at kindergarten predicts academic performance at second grade (N = 94). The results showed that WM skills significantly increase during the time span from…

The present study aims to examine the relationship between developmental language deficit and children's creative ability. For this purpose, we compared the performance of preschool children with Specific Language Impairment (SLI) on general and mathematic creativity tests with that of typically developing children. The findings demonstrated that…

Intellectual abilities are consistently found to be associated to child functioning. To date, however, it is unclear how varying intellectual profiles relate to differential aspects of child functioning. We screened 513 fifth-grade children on their intellectual abilities and selected three groups of gifted children, scoring in the top 10%:…

A common belief in police officers is that guilty suspects' statements are less consistent than innocent suspects'. This could leave guilty suspects more vulnerable to missing inconsistencies externally induced into their alibis. Source monitoring and cognitive load approaches suggest that untruthfulness rather than guilt should predict proneness…

The Cattell-Horn-Carroll (CHC) model presently serves as a blueprint for both test development and a taxonomy for clinical interpretation of modern tests of cognitive ability. Accordingly, the trend among test publishers has been toward creating tests that provide users with an ever-increasing array of scores that comport with CHC. However, an…

Background: Mental capacity assessments currently rely on subjective opinion. Researchers have yet to explore the association between key cognitive functions of rational decision making and mental capacity classifications for people with intellectual disabilities. Method: Sixty-three adults completed the Montreal Cognitive Assessment, which…

Gender difference on spatial visualization has been considered an important factor that impacts the gender gap in academic performance in STEM-related disciplines. The purpose of this meta-analysis was to examine the gender difference on spatial visualization between STEM and non-STEM undergraduate majors. Twenty effect sizes representing STEM…

Human languages typically employ a variety of spatial metaphors for time (e.g., "I'm looking forward to the weekend"). The metaphorical grounding of time in space is also evident in gesture. The gestures that are performed when talking about time bolster the view that people sometimes think about regions of time as if they were locations…

In two experiments, one hundred and sixty-two 6- to 8-year-olds were asked to reason counterfactually about events with different causal structures. All events involved overdetermined outcomes in which two different causal events led to the same outcome. In Experiment 1, children heard stories with either an ambiguous causal relation between…

When the Differential Ability Scales--Second Edition (DAS-II) was developed, the instrument's content, structure, and theoretical orientation were amended. Despite these changes, the "Technical Handbook" did not report results from exploratory factor analytic investigations, and confirmatory factor analyses were implemented using…

Conversations about 'fixed' or innate ability in relation to schools and education have generally considered - though not exclusively so - the psychological and sociological basis of ability, the practicalities and policy formulations. In this article, the author considers the emergent politics of ability and the culture war on social media which…

Background: While delays in cognitive development are detectable during early development in Down syndrome, the neuropsychological and biomedical underpinnings of cognitive skill acquisition in this population remain poorly understood. Method: To explore this issue, 38 infants with Down syndrome [mean chronological age = 9.65 months; SD = 3.64]…

Netrin-1 was initially characterized as an axon guidance molecule that is essential for normal embryonic neural development; however, many types of neurons continue to express netrin-1 in the postnatal and adult mammalian brain. Netrin-1 and the netrin receptor DCC are both enriched at synapses. In the adult hippocampus, activity-dependent…
