Purpose: The toddler years are a critical period for language development and growth. We investigated how event-related potentials (ERPs) to repeated and novel nonwords are associated with clinical assessments of language in young children. In addition, nonword repetition (NWR) was used to measure phonological working memory to determine the…

Two broad theories of visual working memory (VWM) storage have emerged from current research, a discrete slot-based theory and a continuous resource theory. However, neither the discrete slot-based theory or continuous resource theory clearly stipulates how the mental commodity for VWM (discrete slot or continuous resource) is allocated.…

Elementary school students often lack a conceptual understanding of linear measurement, which is revealed by their poor performance when the object to be measured is not aligned with the start of the ruler. Instead of correctly counting the units that correspond to the object (e.g., inches or centimeters), children often use 1 of 2 incorrect…

The development of visual expertise is accompanied by enhanced visual object recognition memory within an expert domain. We aimed to understand the relationship between expertise and memory by modeling cognitive mechanisms. Participants with a measured range of birding expertise were recruited and tested on memory for birds (expert domain) and…

This article reconsiders Case's theory of central conceptual structures (CCS), examining the relation between working memory and the acquisition of quantitative CCS. The lead hypothesis is that the development of working memory capacity shapes the development of quantitative concepts (whole and rational numbers). Study I, with 779 children from…

Research suggests that a central difficulty in dyslexia may be impaired rapid temporal processing. Good temporal processing is also needed for musical perception, which relies on the ability to detect rapid changes. Our study is the first to measure the perception of adults with and without dyslexia on all three dimensions of music (rhythm, pitch,…

Successful reading demands the ability to combine visual-phonological information into a single representation and is associated with an efficient short-term memory. Reading disability may consequently involve an impaired working memory binding of visual and phonological information. The present study proposes two span tasks for assessing…

Elementary schoolchildren's working memory performance (WMP) fluctuates from moment to moment and day to day, yet the underlying mechanisms are not well understood. In the present study, affective states were investigated as predictors of these fluctuations. Interindividual differences in the intraindividual affect--WMP associations were expected,…

Purpose: The current study adopts a systematic approach to the examination of working memory components in pediatric cochlear implant (CI) users by separately assessing contributions of encoding, storage, and retrieval. Method: Forty-nine long-term CI users and 56 typically hearing controls completed forward and backward span tasks with 3 stimulus…

A semantic diagram tool is proposed in this study in order to structure collaborative problem solving (CPS) based on cognitive load theory (CLT). To investigate its effects on transaction cost and the deepening of user understandings, a comparative quasi-experiment was designed and conducted with 49 participants from a university in East China.…

The purpose of this study was to examine the role of executive function (EF) skills (i.e., working memory, cognitive flexibility, and inhibition) in supporting the development of reading fluency in elementary school students with dyslexia. Participants were 47 students (i.e., second to sixth grade) attending a private school in the Mid-South…

How people learn to read is an interesting question which has been investigated by many studies with various approaches. Some recent studies have related learning to read with domain-general abilities and have found a positive relationship between statistical learning and learning to read, as well as between procedural learning and learning to…

This study focuses on the assessment of working memory and linguistic skills in 21 Italian-Russian speaking bilingual children who were born in Italy and inherited Russian from their parents. Their performance was compared to that of 21 monolingual Russian-speaking and 21 monolingual Italian-speaking peers. For the assessment of the two languages…

Similarity is a topic in Geometry which investigates similar elements of a plane. This topic has a high complexity that generates cognitive load in working memory. A deep understanding of the concept is needed to solve similarity problems. Based on cognitive load theory, learning by goal-free problems is suggested since it can minimize cognitive…

Background: Phonological awareness (PA) skills and working memory (WM) are universally regarded as crucial precursors to skilled reading. The orthography of the language being read influences the ease with which a child learns to read. Research has been undertaken on reading in languages with an opaque orthography. Research on the role of PA and…
