The aim of the study was to investigate the developmental trajectory of error monitoring. For this purpose, children (age 7-8), young adolescents (age 13-14) and adults (age 23-24) performed a Go/No-Go task and were compared on overt reaction time (RT) performance and on event-related potentials (ERPs), thought to reflect error detection…

Dotted Moon is a useful and important resource to complement the range of options available to those teaching and learning Moon. Observation of a variety of Moon readers (including those at early stages of literacy as well as more advanced readers) showed that all participants were able to decode dotted Moon characters and engage in educational…

The study compared the productions of 35 articulation impaired children (ages 3 to 10) obtained by picture elicited single word and connected speech sampling methods. Productions were compared on the basis of both the number and type of errors made under the two testing conditions. (Author/PHR)

This study investigated the influence of peer support and leading or misleading questions on reports of a neutral event by 48 children (ages 5 to 10). Younger children made significantly more errors in response to directly misleading questions than to indirectly misleading questions. Peer support did not influence children's prompted recall…

Certain phonological error patterns have been judged to be "unusual" or "idiosyncratic", posing a number of theoretical and clinical problems. This paper reconsiders an especially challenging case of an unusual error pattern documented by Leonard and Brown (1984). T (age 3;8) replaced all word-final consonants (except for labial stops) with [s]…

Background: Problems with subject-verb agreement and phonological (processing) skills have been reported to occur in children with specific language impairment (SLI) and in those with developmental dyslexia, but only a few studies have compared such problems in these two groups. Previous studies have claimed a causal relationship between…

A total of 1,018 signs in one deaf child's naturalistic interaction with her deaf mother, between the ages of 19 and 24 months were analyzed. This study summarizes regular modification processes in the phonology of the child sign's handshape, location, movement, and prosody. First, changes to signs were explained by the notion of phonological…

Perspective-taking, or the ability to demonstrate awareness of informational states in oneself and in others, has been of recent interest in behavioral psychology. This is, in part, a result of a modern behavioral approach to human language and cognition known as Relational Frame Theory, which views perspective-taking as generalized operant…

Tests the effects of stimulus variability on overgeneralization and overdiscrimination errors in children and adults. The subjects (n=64), adults and five-, seven-, and nine-year-old children, participated in a visual discrimination task. (CM)

Investigated the relative effects of developmental level and domain-specific knowledge on 4- to 9-year-olds' ability to identify and make similarity decisions about objects based on haptic or tactile information. Found that older children explored models more exhaustively, found more differentiating features, and made fewer errors than younger…

When 16 parents' and 13 nonparents' conversations with children were examined for evidence of adults' differential responses to children's syntactic, phonological, and semantic errors, results indicated that adults tended to respond differentially to children's language mistakes, with parents showing greater sensitivity than non-parents.

A test of handwriting legibility and 6 perceptual-motor tests were completed by 66 children ages 7-12. Among handwriting error patterns, execution was associated with visual-motor skill and sensory discrimination, aiming with visual-motor and fine-motor skills. The visual-spatial factor had no significant association with perceptual-motor…

Four experiments examined links and differences between children's copying line diagrams and drawing solid objects. Findings suggest that emphasis on order of line copying improves copying performance because line-to-line matching is an important element of the skill, whereas this does not aid drawing of the solid object, in which focus is…

This study investigated the development of the many-to-one counting strategy in 4- year-old children. In the first experiment, 52 children participated. Their development with respect to two kinds of tasks, a hidden-items task and a needed-items task, was studied over four sessions. Children (n = 28) who accurately used the many-to-one strategy in…

Grammatical measures that distinguish language differences from language disorders in bilingual children are scarce. This study examined English past tense morphology in sequential bilingual Spanish/English-speaking children, age 7;0-9;0 (years;months). Twelve bilingual children with language impairment (LI) or history of LI and 15 typically…
