Fiorello et al. (this issue) asserted that as subtest or factor-score variability increases, the overall ability score becomes a less viable predictor ol achievement--and that this is especially the casefor clinical populations. The present study tested the contention that global IQ scores are invalid predictors of achievement in the presence olsign(licant variahility among constituent factors....

The effect of extracorporeal circulation during open heart surgery on changes in intellectual function was studied in 18 children. A group of patients undergoing such surgery was compared to a control group undergoing cardiac surgery without extracorporeal circulation. The Wechsler Intelligence Scale for Children was used to evaluate the patients. No significant differences were found in either...

Twenty people with suspected intellectual disability took the Reynolds Intellectual Assessment Scales (RIAS; C. R. Reynolds & R. W. Kamphaus, 1998) and the Wechsler Adult Intelligence Scale-3rd Edition (WAIS-III; D. Wechsler, 1997) to see if the 2 IQ tests produced comparable results. A t test showed that the RIAS Composite Intelligence Index scores were significantly higher than WAIS-III Full ...

Wechsler's Deterioration Index (WDI) was developed as an indicator of cognitive impairment in adults but has been applied to children, because neuropsychological deficits have often been hypothesized to account for learning difficulties during the development period. Renamed the Wechsler Developmental Index, this measure has been used to discriminate among groups of children with and without le...

The Wechsler Intelligence Scale for Children--Third Edition (D. Wechsler, 1991; WISC-III) is often used to identify subtest-based cognitive strengths and weaknesses that are subsequently used to generate interventions. Given that intelligence is presumed to be an enduring trait, cognitive strengths and weaknesses identified via subtest analysis should also be stable over time. This was evaluate...

One of the important questions that needs to be considered when evaluating cognitive functioning in older adults is whether the scores on the tests have the same meaning as they do in young and middle-aged adults. While it is generally agreed that crystallized intelligence (Gc) measures such as those derived from vocabulary subtests tend to ‘‘hold’’ well with age, barring neurological complicat...

according to the mother's key roles in bringing up emotional and cognitive abilities of mentally retarded children and respect to positive psychology in recent decades, this research is administered to assess the relation between mother's happiness level with cognitive- executive functions (i.e. attention, working memory, inhibition and planning) and facial emotional recognition ability as two ...
