Background: Whether the Flynn effect (the increase in the populations' IQ over time) affects the IQ scores of people with learning disability or borderline learning disability remains unclear. The issue is important as the Flynn effect should alter the number of people eligible for health service resources. A comparison of the Wechsler Adult…

This empirical study compared the average ages at which four children with congenital blindness acquired 29 verbal skills with given age norms for sighted children. The results indicated only small developmental delays in the acquisition of verbal skills in the four children, but a high degree of variability in developmental delays within and…

The purpose of this paper is to explore methods to approximate population invariance without conducting multiple linkings for subpopulations. Under the single group or equivalent groups design, no linking needs to be performed for the parallel-linear system linking functions. The unequated raw score information can be used as an approximation. For…

The purpose of the study was to investigate the relationship between foreign language learning and verbal ability in English as measured by the verbal section of the Scholastic Aptitude Test (SAT) Reasoning Test. Comparing foreign language students to nonforeign language students in this study, the effect of taking a foreign language on SAT verbal…

This study uses historical data to explore the consistency of SAT® I: Reasoning Test score conversions and to examine trends in scaled score means. During the period from April 1995 to December 2003, both Verbal (V) and Math (M) means display substantial seasonality, and a slight increasing trend for both is observed. SAT Math means increase more…

This study investigated the verbal and visuospatial processing and storage skills of children with SLI and typically developing children. Fourteen school-age children with SLI, and two groups of typically developing children matched either for age or language abilities, completed measures of processing speed and storage capacity, and a set of…

The paper studies whether visuospatial working memory (VSWM) and, specifically, recall of sequential-spatial information, can be improved by metacognitive training. Twenty-two fourth-grade children were involved in seven sessions of sequential-spatial memory training, while twenty-four children attended lessons given by their teacher. The…

The aim of this study was to establish the nature of the relations between inhibitory control (IC) and false belief understanding (FBU). Twenty-eight children, participating in an experimental condition, were tested on a battery of FBU and IC tasks every four weeks for six phases of testing. A control group of 14 children completed the battery…

A total of 83 children with different special educational needs (SEN) assessments were contrasted with a control group (N = 40) without special needs on measures that aimed to identify potential areas of strengths as well as weaknesses in these SEN groups. Carefully selected groups of dyslexics, dyspraxics, children with specific language…

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n =…

Background: Narratives have been used by a number of researchers to investigate the language of children with specific language impairment (SLI). While a number of explanations for SLI have been proposed, there is now mounting evidence that children with SLI have limited memory resources. Phonological memory has been the focus of the research on…

Objective: Shaken Baby Syndrome (SBS) is now recognized as being the main cause of severe traumatic brain injury in infancy. However, our understanding of the impact of this type of abuse on child development remains sketchy. The main objective of the current study was therefore to shed light on the cognitive dysfunctions that are particular to…

Research Findings: Few rating scales measure social competence in very young Spanish or Catalan children. We aimed to analyze the psychometric characteristics of the California Preschool Social Competence Scale (CPSCS) when applied to a Spanish- and Catalan-speaking population. Children were rated by their respective teachers within 6 months…

The present investigation examined the validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) with the Woodcock-Johnson III Tests of Cognitive Abilities (WJ-III COG) by administering these instruments in counterbalanced order to 60 college students. Results indicated that the mean CTONI NIQ score was not significantly different from…

Verbal overshadowing has been found to disrupt recognition accuracy when hard-to-describe stimuli are used. The current study replicates previous research on verbal overshadowing with younger people and extends this research into an older population to examine the possible link between verbal expertise and verbal overshadowing. It was hypothesized…
