Tests of measurement invariance are essential to determining whether individual scores or group averages are comparable across populations. While international comparisons of mean IQ scores are common, tests of measurement invariance for intelligence test batteries (necessary for comparisons to be empirically supported) are rare. In this study,…

We used two simple unsupervised machine learning techniques to identify differential trajectories of change in children who undergo intensive working memory (WM) training. We used self-organizing maps (SOMs)--a type of simple artificial neural network--to represent multivariate cognitive training data, and then tested whether the way tasks are…

The purpose of this research study was to examine the overall effect of adaptive learning systems deployed using artificial intelligence technology across a range of relevant variables (e.g., duration, student level, etc.). Following a systematic procedure, this meta-analysis examined literature from 18 academic databases and identified N = 45…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

Background: Multiple perspectives on cognitive development, including Cattell's Investment Theory (1963, 1987), suggest that fluid reasoning (Gf) is foundational to the development of academic knowledge and skills. Yet little is known of the role that Gf may play in reading achievement, particularly in comparison with a larger literature…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

The Vygotskian preschool education program (VPEP) is built around mediation in the context of preschool age-specific activities such as sociodramatic play, constructive play, listening and retelling fairy tales, playing with dollhouses, motor activities, and some others. We used the VPEP as part of the daily curriculum in two pre-K classes at PS…

There is little evidence regarding the benefits of early center-based care attendance (before three years old) for child development and most studies have focused on developed countries. Addressing this gap, this study examines the relationship between center-based care attendance during toddler years and children's cognitive outcomes. Research…

In this study, it was designed to examine the multiple intelligence levels, cognitive, physical and affective levels of the faculty students studying at Hatay Mustafa Kemal University. The population of the study was composed of students studying at Hatay Mustafa Kemal University in 2018-2019 academic year. The sample included 1142 students (Male…

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…

Play is a powerful influence on children's learning and parents can provide opportunities to learn specific content by scaffolding children's play. Parent-child synchrony (i.e., harmony, reciprocity and responsiveness in interactions) is a component of parent-child interactions that is not well characterized in studies of play. We tested whether…

The goal of this study was to investigate reliable cognitive change in epilepsy by developing computational procedures to determine reliable change index scores (RCIs) for the Dutch Wechsler Intelligence Scales for Children. First, RCIs were calculated based on stability coefficients from a reference sample. Then, these RCIs were applied to a…

Criticisms advanced by Felice and Giugliano (2011) of the thesis that IQs in Italy are higher in the north than in the south are answered and new data confirming the thesis are given from the PISA 2009 study and for math and reading abilities in the recent INVALSI study. New genetic data are given showing higher frequency of blond hair the…

Cognitive impairment is common among children born very preterm (VPT), yet little is known about how this risk changes over time. To examine this issue, a regional cohort of 110 VPT (= 32 weeks gestation) and 113 full-term (FT) born children was prospectively assessed at ages 4, 6, 9, and 12 years using the Wechsler Preschool and Primary Scale of…

Do children who go on to develop dyslexia show normal verbal and nonverbal development before reading onset? According to the aptitude-achievement discrepancy model, dyslexia is defined as a discrepancy between intelligence and reading achievement. One of the underlying assumptions is that the general cognitive development of children who fail to…
