In this commentary, I reflect from a neurocognitive perspective on the four chapters on natural number development included in this section. These chapters show that the development of seemingly basic number processing is much more complex than is often portrayed in neurocognitive research. The chapters collectively illustrate that children's…

School systems across the country are transitioning from paper-based testing (PBT) to computer-based testing (CBT). As this technological shift occurs, more research is necessary to understand the practical and performance implications of administering CBTs. Currently, there is a paucity of research using CBTs to examine working memory (WM)…

Mathematical discussions in which students compare alternative solutions to a problem can be powerful modes for students to engage and refine their misconceptions into conceptual understanding, as well as to develop understanding of the mathematics underlying common algorithms. At the same time, these discussions are challenging to lead…

Recent research on fractions has broadened and deepened theories of numerical development. Learning about fractions requires children to recognize that many properties of whole numbers are not true of numbers in general and also to recognize that the one property that unites all real numbers is that they possess magnitudes that can be ordered on…

Aim: The present study investigated the effects of varying the cognitive demands of a memory task (a suprapostural task) while recording postural motion on two groups of children, one diagnosed with developmental coordination disorder (DCD) and an age-matched group of typically developing children. Method: Two groups, each comprising 38 child…

The focus of this paper is on the assessment of the two main processes that children must acquire at the single word reading level: word recognition (lexical) and decoding (nonlexical) skills. Guided by the framework of the dual route model, this study aimed to (1) investigate the impact of item characteristics on test performance, and (2)…

The Assessment of Children's Hand Skills (ACHS) is a new assessment tool that utilizes a naturalistic observational method to capture children's real-life hand skill performance when engaging in various types of activities. The ACHS also intends to be used with both typically developing children and those presenting with disabilities. The purpose…

This study examined how 6-9 year-old English-speaking children and adults establish anaphoric dependencies during auditory sentence comprehension. Using eye-movement monitoring during listening and a corresponding sentence-picture judgment task, we investigated both the ultimate interpretation and the online processing of reflexives in comparison…

In this study, students' use of a new educational Web portal was evaluated with particular emphasis on searching and browsing strategies. The effects and implications of a federated search system are also discussed. Fifty-four students, ranging from 5th to 12th grade, were given five tasks to complete using the SchoolRooms interface. The tasks…

Purpose: This pilot study examined the extent and nature of associations in the linguistic complexity used by child and clinician within conversational interactions. Method: Correlation analyses focused on semantic and morphosyntactic language sample measures from an experienced speech-language clinician and 29 children with language impairment.…

Three studies compared 98 children with spina bifida myelomeningocele (SBM)--a disorder associated with high rates of math disability and spatial deficits--to 94 typically developing children on multidigit subtraction and cognitive addition tasks. Children with SBM were classified into those with reading decoding and math disability, only math…

This article presents a nontechnical explanation of Rasch model logit estimates of pediatric functional ability, an illustration of two alternative transformations of logit estimates of functional ability, and a pragmatic solution to the problem of obtaining a functional ability estimate for a zero or perfect performance score.

Children (ages 5, 7, and 9 years) and young adults completed two visual attention tasks that required them to make a forced choice identification response to a target shape presented in the center of a computer screen. In the first task (high correlation condition) each target was flanked with the same distracters on 80% of the trials (valid…

Three experiments from the late 1970s concerning second language communication strategies are studied for evidence supporting their classification as either avoidance or achievement strategies. The experiments had as subjects native English-speaking children in a French immersion program, adult second language learners of English who were native…
