Computerized assessment of sustained attention: interactive effects of task demand, noise, and anxiety.

abstract：:The standardization sample from the WMS-III (weighted N = 1250) (The Psychological Corporation, 1997; Tulsky & Ledbetter, 2000), which varied in age from 16 to 89, was used to determine whether storage of verbal and spatial information was affected by normal aging. A previous study with the same sample using an analys...
