Persons with mild cognitive impairment (MCI) do not meet criteria for Alzheimer's disease (AD) but are at high risk for developing the disease. Presence of a memory deficit is a key component in the characterization of MCI. This chapter presents empirical studies that attempt to describe and understand the nature of the memory deficit in MCI with a focus on(More)
This study aimed at characterizing the individual variability in three attentional control functions (shifting, inhibition, and updating), among 75 older and 75 younger adults. It also examined the intellectual and health variables associated with different cognitive profiles. Cluster analyses identified three separate attentional control profiles for both(More)
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 MCI patients(More)
OBJECTIVES This study assessed the effect of aging on 3 attentional control functions (ACFs)--shifting, inhibition, and updating--and on their contribution to working memory (WM) tasks. METHODS Complex WM tasks (the Brown-Peterson procedure, the reading span, and the alpha span) and tasks used to derive composite measures of the ACFs were administered to(More)
