The use and understanding of self-presentational display rules (SPDRs) was investigated in 21 children with high-functioning autism (FHA), 18 children with Asperger's disorder (AspD) and 20 typically developing (TD) children (all male, aged 4- to 11-years, matched on mental age). Their behaviour was coded during a deception scenario to assess use…

Purpose: To examine perceptual deficits as a potential underlying cause of specific language impairments (SLI). Method: Twenty-one children with SLI (8;7-11;11 [years;months]) and 21 age-matched controls participated in categorical perception tasks using four series of syllables for which perceived syllable-initial voicing varied. Series were…

Working memory is an important theoretical construct among children, and measures of its capacity predict a range of cognitive skills and abilities. Data from 9- and 11-year-old children illustrate how a chronometric analysis of recall can complement and elaborate recall accuracy in advancing our understanding of working memory. A reading span…

Behavioral, neuropsychological, and brain imaging research points to a dedicated system for processing number that is shared across development and across species. This foundational Approximate Number System (ANS) operates over multiple modalities, forming representations of the number of objects, sounds, or events in a scene. This system is…

This study examined developmental trends in object and spatial working memory (WM) using heart rate (HR) to provide an index of covert cognitive processes. Participants in 4 age groups (6-7, 9-10, 11-12, 18-26, n=20 each) performed object and spatial WM tasks, in which each trial was followed by feedback. Spatial WM task performance reached adult…

This study examines the development of children's ability to reason about proportions that involve either discrete entities or continuous amounts. Six-, 8- and 10-year olds were presented with a proportional reasoning task in the context of a game involving probability. Although all age groups failed when proportions involved discrete quantities,…

Objective: Time reproduction is deficient in children with attention-deficit/hyperactivity disorder (ADHD). Whether this deficit is familial and could therefore serve as a candidate endophenotype has not been previously investigated. It is unknown whether timing deficits are also measurable in adolescent children with ADHD and nonaffected…

Much developmental work has been devoted to "scalar implicatures." These are implicitly communicated propositions linked to relatively weak terms (consider how "Some" pragmatically implies "Not all") that are more likely to be carried out by adults than by children. Children tend to retain the linguistically encoded…

This observational study supplements the strong and consistent link found between childhood depression and deficits in interpersonal functioning by examining the relationship between a high versus low score on the Children's Depression Inventory (CDI) and children's emotions when interacting with their best friends. High-CDI and low-CDI target…

Investigated potential influences of general processing capacity and sustained selective attention on the temporal processing of a group of children with specific language impairment and a group of age-matched controls. Results suggest that the SLI children did not evidence a basic temporal processing deficit. (Author/VWL)

The present study was designed to determine whether parents (three mothers and one grandmother) could implement CBI with SP reliably for teaching community skills to their children and the effects of parent-delivered intervention on teaching the community skills. Maintenance and generalization effects of the intervention were also analyzed in the…

Recent data suggest that subthreshold presentation of emotional information is relayed to the amygdala along subcortical pathways. We examined the effect of backward masked neutral and anxious faces on the social decisions of a group of high functioning children with autism ages 7-13 years and matched controls. Participants were asked to select…

Individuals with the rare genetic disorder, Williams syndrome, have an unusual cognitive profile with relatively good language abilities but poor non-verbal and spatial skills. This study explored the interaction between linguistic and spatial functioning in Williams syndrome by investigating individuals' comprehension of spatial language. A group…

Purpose: This study presents a meta-analysis of the difference in nonword repetition performance between children with and without specific language impairment (SLI). The authors investigated variability in the effect sizes (i.e., the magnitude of the difference between children with and without SLI) across studies and its relation to several…

In this article, the authors discuss and examine how to develop time sharing using a dual motor task and its effects. They state that when one is required to perform two tasks at the same time (time sharing), an individual may experience difficulty in expressing one or both of the tasks. This phenomenon, known as interference, has been studied…
