This study examined the effects of traumatic brain injury (TBI) on Wechsler Memory Scale-III (WMS-III) performance. Since poor effort potentially contaminates results, effort was explicitly assessed and controlled using two well-validated cognitive validity indicators, the Portland Digit Recognition Test (PDRT) and Reliable Digit Span (RDS).

During hypoosmotic stress, membrane vesicles enriched in acetylcholine receptors become more permeable to external tracer molecules. When vesicles are immersed in 3 volumes of water containing 22Na+, 50-70% of 22Na+ equilibration is attained within 90 s. On the other hand, the uptake of 22 Na+ is greatly diminished only 6-10 s after an osmotic shock, and(More)
The current study assessed performance validity on the Stroop Color and Word Test (Stroop) in mild traumatic brain injury (TBI) using criterion-groups validation. The sample consisted of 77 patients with a reported history of mild TBI. Data from 42 moderate-severe TBI and 75 non-head-injured patients with other clinical diagnoses were also examined. TBI(More)
