The condition of hydrocephalus (HCP) and its secondary sequelae have been well documented. Previous reports have documented the impact of an enlarging ventricular system on the developing brain and neuropsychological consequences in HCP children. Furthermore, most children with shunted HCP have been reported to demonstrate poorer non-verbal intelligence quotient (IQ) scores relative to verbal I...

The Wechsler Adult Intelligence Scale was administered serially to 40 severely head-injured adults, and the results compared with a matched group of 40 non-injured men. The scores on the verbal subtests showed less initial impairment and were faster to recover to the level of the comparison group than were the non-verbal subtest scores. Verbal IQ of the head-injury group approached that of the ...

BACKGROUND Impairments in executive functioning (EF) and intelligence quotient (IQ) are frequently observed in children with attention deficit hyperactivity disorder (ADHD). The aim of this paper was twofold: first, to examine whether both domains are viable endophenotypic candidates for ADHD and second to investigate whether deficits in both domains tend to co-segregate within families. METH...

We administered a semantic verbal fluency (SVF) task to two groups of children (age range from 5 to 8): 47 diagnosed with Autism Spectrum Disorder (ASD Group) and 53 with typical development (Comparison Group), matched on gender, chronological age, and non-verbal IQ. Four specific indexes were calculated from the SVF task, reflecting the different underlying cognitive strategies used: clusterin...

OBJECTIVES Few studies have prospectively investigated associations of child cognitive ability and behavioural difficulties with later eating attitudes. We investigated associations of intelligence quotient (IQ), academic performance and behavioural difficulties at 6.5 years with eating attitudes five years later. METHODS We conducted an observational cohort study nested within the Promotion ...

We studied the age-related differences in inspection time and multiple cognitive domains in a group of monozygotic (MZ) and dizygotic (DZ) twins aged 7 to 17 years. Data from 111 twin pairs and 19 singleton siblings were included. We found clear agerelated trends towards more efficient visual information processing in older participants. There were substantial correlations between inspection ti...

This study examined the utility of word recognition scores for estimating actual Verbal IQ scores obtained from 1-5 years earlier. Participants were 271 persons remaining normal and 24 initially normal persons who developed cognitive impairment over longitudinal follow-up. A previously published regression equation based on education and the American modification of the National Adult Reading T...

BACKGROUND The literature is mixed as to the relationship between intelligence quotient (IQ) and Posttraumatic Stress Disorder (PTSD) symptomatology in adult populations. Even less is known about the relationship in children who have been traumatized. METHODS Fifty-nine children and adolescents (mean age = 10.6) with a history of interpersonal violence were evaluated with respect to PTSD symp...

INTRODUCTION Although cognitive impairments in adults with Noonan syndrome seem to be limited to a low-average intelligence and slower processing speed, studies in children with Noonan syndrome have demonstrated more extensive cognitive problems. These include deficits in language skills, memory, attention, and executive functioning. This longitudinal study is the first to investigate intellect...

Predicting Student Performance in Verbal Math Problems Based on Cognitive, Metacognitive, and Affective Factors F. Karimi, Ph.D. A.R. Moraadi, Ph.D. P. Kadivar, Ph.D. R. Kormi Noori, Ph.D. To determine the predictive role of metacognitive, cognitive, and affective factors in solving verbal math problems, a cluster sample of 450 junior high school  students was given ...
