Yilmaz, Yavuz; Yetkin, Yalçin – Educational Research and Reviews, 2014
The relationship between mean intelligence quotient (IQ), hand preferences and visual memory (VM) were investigated on (N = 612) males and females students trained in different educational programs in viewpoint of laterality. IQ was assessed by cattle's culture Fair intelligence test-A (CCFIT-A). The laterality of the one side of the body was…

Rutherford, M. D.; Troje, Nikolaus F. – Journal of Autism and Developmental Disorders, 2012
Biological motion is easily perceived by neurotypical observers when encoded in point-light displays. Some but not all relevant research shows significant deficits in biological motion perception among those with ASD, especially with respect to emotional displays. We tested adults with and without ASD on the perception of masked biological motion…

Ambery, Fiona Z.; Russell, Ailsa J.; Perry, Katie; Morris, Robin; Murphy, Declan G. M. – Autism: The International Journal of Research & Practice, 2006
There is some consensus in the literature regarding the cognitive profile of people with Asperger syndrome (AS). Findings to date suggest that a proportion of people with AS have higher verbal than performance IQ, a non-verbal learning disability (NVLD) and impairments in some aspects of executive function (EF). However, there are few published…

Buchholz, Judy; McKone, Elinor – Dyslexia, 2004
We examine the visual processing of high-functioning adults with developmental dyslexia (mean Performance IQ=126.5) and current phonological problems. In comparison to an age- and IQ-matched control group, the group with dyslexia showed deficits in two tasks associated with magnocellular/dorsal pathway function. For the "frequency doubling"…

Conners, Frances A.; Rosenquist, Celia J.; Atwell, Julie A.; Klinger, Laura Grofer – Education and Training in Mental Retardation and Developmental Disabilities, 2000
Nine adults with Prader-Willi syndrome (PWS) and nine age- and IQ-matched adults with PWS completed standardized tests of long-term and short-term memory, visual and auditory processing, and reading and mathematics achievement. Contrary to previous findings, long-term memory in PWS subjects was strong relative to IQ and there was no evidence that…

Kavale, Kenneth A.; Forness, Steven R. – Learning Disability Quarterly, 2000
A meta-analysis of 267 studies conducted between 1950-1980 found that auditory and visual perceptual skills can successfully increase the accuracy of predicting reading achievement, but the magnitude of increases in predictive accuracy was contingent upon the combination of variables studied and was significantly reduced if an IQ score was known.…
