Research Interests
I am interested in the cognitive and
neural bases of working memory, a system that briefly stores and processes
information on line; this mechanism seems to lie at the heart of higher
mental processes. Recently, I have been focusing on the "executive
processes" associated with working memory, particularly (1) the process
of selectively attending to relevant information in memory while inhibiting
irrelevant information, and (2) the process of switching attention from one
mental representation or process to another.
Much of the research involves the
neuroimaging of normal young participants, but some of the research on
attentional processes involves studies with special populations, including
normal older participants, patients with Alzheimer's Disease (AD), and
depressed people. Another fundamental mechanism of interest is our ability to
categorize novel objects as instances of familiar categories. This mechanism
is central to all aspects of cognition. Again, some of the research involves
special populations, including AD patients, frontal patients, and amnesiac
patients.
