Background: This study presents two experiments that investigated whether children with autism were susceptible to the Thatcher illusion. Perception of the Thatcher illusion requires being able to compute second-order configural relations for facial stimuli. Method: In both experiments children with autism were matched for non-verbal and verbal…

Background: The objective of this study is to identify intact and deficient cognitive processes in children with attention deficit hyperactivity disorder (ADHD) and children with high functioning autism (HFA). Method: Three rigorously diagnosed groups of children aged between 6 and 12 years (54 ADHD, 41 HFA, and 41 normal controls) were tested on…

Background: Previous research suggests that the phenotype associated with Asperger's syndrome (AS) includes difficulties in understanding the mental states of others, leading to difficulties in social communication and social relationships. It has also been suggested that the first-degree relatives of those with AS can demonstrate similar…

This study focused on English as L2 in a group of Norwegian dyslexic 12 year olds, compared to an age and gender matched control group. Norwegian school children learn English from the first grades on. The subjects were assessed with a test battery of verbal and written tasks. First, they were given a comprehension task; second, a model sentence…

Austin Independent School District provided full-day prekindergarten to 5,196 4-year-olds in 2008-2009 at 66 schools. Seventy percent or more of students made measureable gains on a test of receptive vocabulary, and average gains showed growth about two times greater than that expected for 4-year-olds after a 7-month period.

In a sample of 92 children aged 6-13 years this study investigates the normal developmental change in the relation between executive functioning (EF) and the core behavioural symptoms associated with attention deficit hyperactivity disorder (ADHD) (hyperactivity/impulsivity and inattention) as well as symptoms often co-occurring with childhood…

This study examined the effect of child temperament, symptom severity, verbal ability and level of functioning on maternal stress in 43 Greek mothers of children and young people with autism spectrum disorder. Symptom severity was assessed by the CARS, level of functioning by the PEP, temperament by the Dimensions of Temperament Scale (DOTS-R) and…

The Arabic Picture Vocabulary Test (APVT) was derived from the Peabody Picture Vocabulary Test in order to provide an estimate of a student's acquired verbal ability in Arabic (Modern Standard Arabic) through his or her aural vocabulary. It is an individually administered norm-referenced power test for students aged 5 to 9 plus years. Each item…

The Internal/External (I/E) Frame of Reference Model and the structure of students' self-concept in various academic subjects were examined using 195 Grade 10 Chinese students in Hong Kong. Results of structural equation analyses supported the following: (1) the distinction between Chinese and English as two independent academic subjects (rather…

The reasoning skills tapped by the analytical measure of the Graduate Record Examinations were studied by examining how performance on its constituent type items relate to alternative criteria. Another objective was to ascertain the extent to which additional information on examinees' analytical skills might be obtained from further analyses of…

The Wechsler Intelligence Scale for Children (WISC) has a long history, dating back to the 1930s, when it was devised specifically for measuring the intelligence of children through verbal and performance subtests. Intelligence quotients (IQs) are developed for verbal and performance skills. The subtests, their factors, indices derived from them,…

The Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet: Fourth Edition (S-B:FE) were administered in counterbalanced order to a sample of 20 middle-class preschool children (11 males and 9 females) attending the Early Childhood Preschool Center located in a suburban area of a large midwestern city. Subjects' mean age was 4…

This paper examines cognitive processing problems associated with attention deficit disorders (ADD) and their relationship to learning disabilities in elementary and secondary students. Children with ADD, medicated (N=20) and unmedicated (N=21), were compared on the Raven test of Progressive Matrices and other tests with children who had been…

The relationship of verbal skills to performance on the National Teacher Examinations Core Battery Test of General Knowledge was examined, using data from the June 1986 national administration. Differences in General Knowledge scores for self-identified Black and White examinees were found and were shown to interact with levels of achievement on…

The present investigation examined the content specificity of math and English anxieties, tested the generality of predictions from the internal/external (I/E) frame of reference model to anxiety responses, and studied sex differences in anxiety responses. Structural equation models, using LISREL, were fit to data from the High School and Beyond…
