Examined how object shape, taxonomic relatedness, and prior lexical knowledge influenced children's overextensions (e.g., referring to pomegranates as apples). Researchers presented items that disentangled the three factors and used a novel comprehension task where children could indicate negative exemplars. Error patterns differed by task and by…

In this study, African American English (AAE)-speaking children's comprehension of 2 different types of double negative sentences was examined and contrasted with that of a comparison group of Standard American English (SAE)-speaking children. The first type of double negative, negative concord, involves 2 negative elements in a sentence that are…

Configural visual abilities in thirteen children with Williams syndrome (WS) compared to 13 children matched on mental age and 13 children matched on chronological age. Configural abilities were tested through four tasks (1) Silhouette (2) Fragmented (3) Mooney and (4) overlapping figures. In the first three tasks, it was necessary to take into…

We investigated the role of executive and spatial representational processes in impaired performance of block construction tasks by children with Williams syndrome (WS), a rare genetic defect that results in severely impaired spatial cognition. In Experiment 1, we examined performance in two kinds of block construction tasks, Simple Puzzles, in…

Tasks with adult learners have been discussed extensively in the language learning literature whilst studies about children using tasks are less widespread. Children's ability to interact on tasks with each other grows steadily with age. This paper reports on the differences observed in the interactions of 10-year-old children and adult learners.…

Objective: The authors investigated line bisection performance in children with Attention-Deficit/Hyperactivity Disorder (AD/HD) subtypes. Previous research with neurotypical children found a rightward bias with right-hand use and a leftward bias with left-hand use; however, research with AD/HD participants has failed to similarly measure the…

Contrary to empirical reports of inhibitory dysfunction in ADHD, parental reports suggest that when playing computer games, the inhibitory abilities of children with ADHD are unimpaired. This small-scale preliminary investigation into this phenomenon looks at inhibition of an ongoing response and activity exhibited by children with ADHD between 6…

Background: Investigations of the cognitive processes underlying specific language impairment (SLI) have implicated deficits in the storage and processing of phonological information, but to date these abilities have not been studied in the same group of children with SLI. Aims: To examine the extent to which deficits in immediate verbal…

Purpose: Research examining the relationship between spontaneous and imitated productions for phonological analysis has indicated that the inclusion of imitated productions may overestimate children's phonological abilities. Previous research in this area has included only English-speaking children. The purpose of this study was to determine what,…

Performance on an emotional labeling task in response to schematic facial patterns representing five basic emotions without the concurrent presentation of a verbal category was investigated in 40 parents of children with autism and 40 matched controls. "Autism fathers" performed worse than "autism mothers," who performed worse than controls in…

Background: This study investigated whether processing emotionally salient information such as emotional facial expressions influences the performance on a cognitive control task in pediatric anxiety and depression. Methods: The sample included 68 participants between 8 and 16 years of age selected into three diagnostic groups: Anxiety Disorder…

This research investigates the development of analogy, in particular, the study of the development of systematicity in analogy. Systematicity refers to the mapping of systems of mutually constraining relations, such as causal chains or chains of implication. A preference for systematic mappings is a central aspect of analogical processing in…

Piaget's ideas are discussed: that the basic thrust of education is determined by the intellectual development of the child, that the child's intelligence develops in definite stages, and that the goal of the developmental process is to reason in logical terms. (MLW)

This paper investigates the development of interactive communication skills in 170 children aged 7 to 13. Results indicate that the development of interactive communication skills is rather different from the process of language acquisition both in the extended timescale involved and in the considerable variability exhibited by speakers of…
