Possin, Katherine L.; Laluz, Victor R.; Alcantar, Oscar Z.; Miller, Bruce L.; Kramer, Joel H. – Neuropsychologia, 2011
Figure copy is the most common method of visual spatial assessment in dementia evaluations, but performance on this test may be multifactorial. We examined the neuroanatomical substrates of figure copy performance in 46 patients with Alzheimer's disease (AD) and 48 patients with the behavioral variant of Frontotemporal dementia (bvFTD). A group of…

Boles, David B. – Brain and Cognition, 2011
Socioeconomic status (SES), a variable combining income, education, and occupation, is correlated with a variety of social health outcomes including school dropout rates, early parenthood, delinquency, and mental illness. Several studies conducted in the 1970s and 1980s largely failed to report a relationship between SES and hemispheric asymmetry…

Snyder, Kelly A. – Infancy, 2010
The present study used event-related potentials (ERPs) to monitor infant brain activity during the initial encoding of a previously novel visual stimulus, and examined whether ERP measures of encoding predicted infants' subsequent performance on a visual memory task (i.e., the paired-comparison task). A late slow wave component of the ERP measured…

Belmonte, Matthew K.; Gomot, Marie; Baron-Cohen, Simon – Journal of Child Psychology and Psychiatry, 2010
Background: In addition to their more clinically evident abnormalities of social cognition, people with autism spectrum conditions (ASC) manifest perturbations of attention and sensory perception which may offer insights into the underlying neural abnormalities. Similar autistic traits in ASC relatives without a diagnosis suggest a continuity…

Nijman, Henk; Merckelbach, Harald; Cima, Maaike – Journal of Sexual Aggression, 2009
Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence…

Samar, Vincent J.; Parasnis, Ila – Brain and Cognition, 2007
Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. "Brain and Cognition," 49, 170-181; Samar, V. J., & Parasnis, I. (2005).…
