Rapid Naming and Phonemic Awareness in Children With or Without Reading Disabilities and/or ADHD.

Employing a large sample of children from Dutch regular elementary schools, this study assessed the contributing and discriminating values of reading disability (RD) and attention-deficit/hyperactivity disorder (ADHD) to two types of phonological processing skills, phonemic awareness (PA) and rapid automatized naming (RAN). A second objective was to investigate whether comorbidity of RD and ADHD should be considered as an additive phenomenon as to RAN and PA. A total of 1,262 children, aged 8 to 13 years, were classified as RD ( n = 121), ADHD ( n = 17), comorbid (RD+ADHD; n = 16), or control ( n = 1,108).

Rapid Naming and Phonemic Awareness in Children With Reading Disabilities and/or Specific Language Impairment: Differentiating Processes?

Purpose: The objective of this study was to assess and compare the predictive values of group membership for rapid automatized naming (RAN) and phonemic awareness (PA) in Dutch school children with and without reading disabilities (RD) or specific language impairment (SLI).

Method: A composite word reading index and a formal SLI diagnosis were used to classify a total of 1,267 children aged 8 to 13 years old either as RD-only (n = 126), SLI-only (n = 21), comorbid (RD+SLI; n = 30), or typically developing (n = 1,090). RAN and PA were assessed with 4 standardized subtests.

The attentional blink in typically developing and reading-disabled children.

This study's research question was whether selective visual attention, and specifically the attentional blink (AB) as operationalized by a dual target rapid serial visual presentation (RSVP) task, can explain individual differences in word reading (WR) and reading-related phonological performances in typically developing children and reading-disabled subgroups. A total of 407 Dutch school children (Grades 3-6) were classified either as typically developing (n = 302) or as belonging to one of three reading-disabled subgroups: reading disabilities only (RD-only, n = 69), both RD and attention problems (RD+ADHD, n = 16), or both RD and a specific language impairment (RD+SLI, n = 20). The RSVP task employed alphanumeric stimuli that were presented in two blocks.

Learning capacity in adolescents with mild intellectual disabilities.

Scores on a learning potential test (the Hessels Analogical Reasoning Test) were examined to assess how to provide a better estimate of the learning capacity of students with mild intellectual disabilities compared to IQ scores. As a criterion, a dynamic test of chemistry learning was used. 46 adolescents from a special education institute participated.

The moderator effect of test anxiety in the relationship between test expectancy and the retention of prose.

The effect of test expectancy and test anxiety on the retention of prose is not yet profoundly examined in an ecologically valid learning context. The influence of test expectancy, test anxiety, and differences in intelligence on the retention of prose was addressed in the hypothesis that test anxiety would act as a moderator between test expectancy and memory retention of prose. Also examined was whether this relation would still be valid if differences in general intelligence were controlled.
