My 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).

The methods I use to address these questions include: behavioural measures, eye tracking, and fMRI.
