Several studies have revealed the importance of executive functioning processes for school learning. However, research examining which specific executive functions (EFs) can influence written expression is scarce. This work aimed at i) analyzing the relationship between different EF tasks and different writing tasks (writing a narrative text vs. writing an expository text) and ii) studying whic...

The current study addresses gaps in our understanding of the relationship between creative cognition, intelligence (IQ), and executive functioning (EF). Undergraduate students completed an IQ test, verbal figural divergent thinking (DT) tests, a self-assessment EF, across four sessions. Participant data (N = 199) were analyzed using linear regression PROCESS moderation models. Results demonstra...

Forty three children aged 6 to 16 years with a documented history of idiopathic infantile hypercalcaemia were assessed on a variety of cognitive and behavioural measures. No relation was found between the age at which hypercalcaemia was diagnosed and subsequent full scale intelligence quotients (IQ) and reading or spelling abilities. Verbal IQ was, however, significantly higher than performance...

Volumetric measures of the brain and ventricles were derived from CT films and related to intellectual variables from the Wechsler Adult Intelligence Scale (WAIS). Subjects were patients referred for neurological examination for headache or somatic complaints, sometimes accompanied by anxiety or dysphoric affect (N = 41), for whom a comprehensive neurological work-up revealed no evidence of abn...

Principal axis factor analyses of the Rorschach Comprehensive System (CS) in a clinical sample of 152 adolescents yielded three clearly defined factors: Synthesized Complexity (defined by Zf, DQ+, and F%), Productivity (defined by R, D, and Dd), and Form Quality (defined by X+%, F+%, and X-%). Variables on the Synthesized Complexity and Form Quality factors were generally correlated with Wechsl...

gender ratio between cases and controls was unequal, albeit non-significantly so, this could not account for the marked differences observed in IQ scores. On the one hand, the difference between the two groups was around one standard deviation, which is much more than the commonly observed difference of 0 to 1 points between genders (Hedges & Nowell, 1995). This was the case both for verbal (di...

Adults with schizophrenia present cognitive impairments, as do individuals at ultra-high risk for the disorder, youth with relatives with schizophrenia spectrum disorders, and children with antecedents of schizophrenia. The present study aimed to determine if impairments in childhood differed depending on the definition of risk and/or on the degree of relatedness to an affected individual, and ...

Intellectual asymmetry with superiority of verbal skills to spatial skills frequently characterises patients with schizophrenia, but it is unclear whether this pattern also reflects genetic susceptibility to the disorder. We examined the association of a continuous measure of genetic liability to schizophrenia with Verbal-Spatial Contrast IQ (an index of intellectual asymmetry) in 108 first-deg...

BACKGROUND Happiness and higher intelligent quotient (IQ) are independently related to positive health outcomes. However, there are inconsistent reports about the relationship between IQ and happiness. The aim was to examine the association between IQ and happiness and whether it is mediated by social and clinical factors. Method The authors analysed data from the 2007 Adult Psychiatric Morbidi...

AIMS The aim of this study was to determine neuropsychological performance in apparently cognitively, mentally, and physically healthy abstinent alcohol-dependent subjects compared with control subjects who were recruited for a number of different neuroimaging studies. METHODS All subjects completed a battery of neuropsychological tests as part of the neuroimaging protocol. RESULTS The grou...
