Three groups of patients with dementia of the Alzheimer type (mildly, moderately and severely demented) and two groups of healthy older adults (73 and 82 yr old) were examined on free and cued recall of subject-performed tasks (SPTs) or verbally presented sentences depicting the same verbal information as the SPTs. Results indicated that all groups examined(More)
Young, old, alcohol intoxicated, and sleep deprived subjects studied weakly and strongly related word pairs, and were tested in lexical decision priming and cued recall. Results showed memory deficits for old, alcohol intoxicated, and sleep deprived subjects in cued recall of weakly related pairs. In contrast, there were no differences between these three(More)

The common denominator of these experiments was that contextual or cognitive support had been provided at study and/or test. The(More)
The purpose of this study was to examine whether cholinergic treatment of age-associated memory impairment with Linopirdine (DUP 996), a derivate of phenylindoline, affects explicit memory, implicit memory, and primary memory. We also assessed cognitive decision making in a reaction time test. Explicit memory was assessed by face recognition, word recall(More)
