We describe the clinical impact of the RehaCom computerized cognitive training program instituted in the International Neurological Restoration Center for rehabilitation of brain injury patients. Fifty patients admitted from 2008 through 2010 were trained over 60 sessions. Attention and memory functions were assessed with a pre- and post-treatment design, using the Mini-Mental State Examination...

The reliability and factorial validity of the Wechsler Intelligence Scale for Children–Fifth Edition: Canadian (WISC-V) was investigated. The higher-order model preferred by Wechsler (2014b) contained five group factors but lacked discriminant validity. An alternative bifactor model with four group factors and one general factor, akin to the traditional Wechsler model, exhibited the best global...

Apolipoprotein E (APOE) genotype is a possible influence on nonpathological cognitive aging. The authors studied 462 community-dwelling, 79-year-old people born in 1921, whose childhood IQ had been assessed in the Scottish Mental Survey of 1932 (Scottish Council for Research in Education, 1933). Adjusting for sex, childhood IQ, and self-reported illnesses, the authors found that those with an A...

BACKGROUND The neurocognitive functioning of patients with schizophrenia is likely to decline at the early stage of the illness. More evidence is needed to determine whether deficits in certain domains of neurocognition precede the onset of illness and can predict the onset of psychosis. METHODS Subjects were recruited from the SOPRES study in Taiwan. A neuropsychological battery including th...

The Processing Speed Index (PSI) was first introduced on the Wechsler Intelligence Scale, Third Edition (WISC-III; D. Wechsler, 1991), and little is known about its clinical significance. In a referred sample (N 980), children with neurological disorders (ADHD, autism, bipolar disorder, and LD) had mean PSI and Freedom from Distractibility Index (FDI) scores that were below the group mean IQ an...

Purpose: Hemispheric dominance is associated with more activity in one half of the body, which very important presence a relationship between intelligence and brain lateralization. Delayed language development children undergoing cochlear implantation can have deleterious effects on their growth, academic performance, adaptation, social interactions. Regarding this, present study aimed to deter...

A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or general level are Wechsler scales (46.9%), Britis...

We present an end-to-end system for automatically scoring spoken responses to a narrative recall test administered to seniors when screening for cognitive impairment. In Wechsler Logical Memory (WLM) test, a patient listens to a brief narrative, then retells the story once immediately and again after a brief delay. We transcribe the retellings automatically using an ASR system, align the transc...

Executive dysfunction is a common symptom among patients with attention deficit hyperactivity disorder (ADHD) and/ or Mathematical Learning disability (MLD). Current research evidence indicates that anxiety can lead to numerous cognitive deficits. Therefore, by comparing executive functioning in children ADHD/MLD, who have high and low levels of anxiety, the present study examined probable role...
