This study attempted to determine whether children with the combined subtype of attention-deficit/hyperactivity disorder (ADHD) have impairments in cognitive functioning and motor skills. The specific effect of the comorbidity of learning disabilities (LD) was also investigated. A battery of cognitive tests was administered to 26 children with a…

This study explored the effects of a reciprocal teaching intervention designed to enhance the lecture comprehension skills of college students. Forty low-verbal ability students and 40 high-verbal ability students (as measured by SAT scores) were chosen for the study and randomly assigned to experimental or control groups. The experimental groups…

Explains the motivation impairment effect (MIE) hypothesis, in which deceivers who are highly motivated to succeed suffer detrimental effects on nonverbal performance yet facilitate effects on verbal performance for less motivated deceivers. Challenges this hypothesis by proposing motivation enhances verbal and nonverbal performance irrespective…

Some psychometric models are presented that belong to the larger class of latent response models (LRMs). Following general discussion of LRMs, a method for obtaining maximum likelihood and some maximum "a posteriori" estimates of the parameters of LRMs is presented and applied to the conjunctive Rasch model. (SLD)

Accurate diagnosis of psychotic disorders may be very difficult in youth with intellectual disabilities. The authors reviewed the assessment, treatment and follow-up of 21 youths with ID referred because of early onset of psychotic symptoms. Just over one half of the patients had a diagnosis of schizophrenia or schizo-affective disorder. One third…

From the cognitive model of multimedia learning proposed by [Schnotz, W., & Barnett, M. (2003). Construction and interference in learning from multiple representation. "Learning and Instruction, 13", 141-156], two hypotheses regarding the learning of spatial arrangements of objects were derived: the integration hypothesis and the multiple source…

This study examined the construct validity of antisocial personality disorder (ASPD) diagnosed in adolescence. Boys and girls were grouped by history of DSM-III-R conduct disorder (CD) and ASPD: Controls (n = 340) had neither diagnosis; CD Only (n = 77) had CD by age 17 but no ASPD through age 20; Adolescent ASPD (n = 64) had ASPD by age 17. The…

This study examined age-related changes in narrative speech of 79 adults aged 40-91 who told stories from their pictorial representations. Quantity, information content and cohesion of narratives were analysed using a detailed transcription and codification system. We carried out a LISREL analysis to study relationships between narrative…

This study explored the structure of verbal and visuospatial short-term and working memory in children between ages 4 and 11 years. Multiple tasks measuring 4 different memory components were used to capture the cognitive processes underlying working memory. Confirmatory factor analyses indicated that the processing component of working memory…

This longitudinal study examined a comprehensive set of predictors of preschool language performance in a sample of children of adolescent mothers. Six domains of risk (low maternal verbal ability, intergenerational risk, contextual risk, relational risk, home environmental risk, and child characteristics) for poor preschool language development,…

The study with 60 autistic children (between 3 and 9-years-old) found that children with high-verbal imitation skill did equally well in any of four different modes of language training presentation while those with low-verbal imitation skill did less well in all modes and poorest in the speech-alone condition. (Author/DB)

The present study examined whether ADHD children exhibit low verbal IQ (VIQ) and distinguishable test profile on the Verbal comprehension (VC) and Freedom from distractibility (FFD) factors, and whether gender influences their verbal abilities. At the Laboratory of Neuropsychology of the Department of Special Education, University of Thessaly,…

The study evaluated narrative production in seven severe to profoundly hearing impaired adolescents in an attempt to determine whether syntactic prowess would predict which subjects would be more adept at narrative production, in terms of the story grammar conventions used, and the cohesive devices used when narrating a story to a naive listener.…

Language sample data from normal subjects (ages 40-79) were collected to determine how normal aging might affect performance on a picture description task, routinely used for assessment of aphasic individuals. Only an increase in the number of paraphasias and a decrease in communication efficiency correlated with increased age. (DB)

Classical research operations in the cognitive sciences concern categorizations as well as classifications, and have been strongly influenced by nomological approaches. As a consequence, information processing has been explained with reference to syntactic-semantic models. Because of an absence of structural implications, personal interpretations…
