Sylvain-Roy, Stephanie; Bherer, Louis; Belleville, Sylvie – Brain and Cognition, 2010
Temporal preparation was assessed in 15 Alzheimer's disease (AD) patients, 20 persons with mild cognitive impairment (MCI) and 28 healthy older adults. Participants completed a simple reaction time task in which the preparatory interval duration varied randomly within two blocks (short versus long temporal window). Results indicated that AD and…

Use of the Hayling Task to Measure Inhibition of Prepotent Responses in Normal Aging and Alzheimer's Disease
Peer reviewed Peer reviewed
Direct linkDirect link
Belleville, Sylvie; Rouleau, Nancie; Van der Linden, Martial – Brain and Cognition, 2006
This study measures the effect of Alzheimer's disease (AD) and normal aging on the inhibition of prepotent responses. AD patients, normal aged controls, and young subjects were tested with the Hayling task, which measures the ability to inhibit a semantically constrained response, and with the Stroop procedure. AD patients showed a severe deficit…
