research focuses on age differences in attentional control and how these
differences influence subsequent memory performance. I am particularly
interested in how older adults' lessened ability to inhibit irrelevant
distraction, from both the environment and internally generated thoughts, may
lead them to form broad associations across events occurring in close spatial
and temporal contiguity. Older adults, and others with compromised inhibitory
abilities, may have a broader sense of "the now", in that boundaries between
distinct events may become more blurred as a result of poor inhibitory
control. While these broad associations may typically lead to interference at
retrieval and thus, poorer memory performance, I am particularly interested
in situations in which older adults' broader associative knowledge may give
them an advantage over younger adults (e.g., during creative problem solving).
methods I use to address these questions include: behavioural measures, eye
tracking, and fMRI.
