RESEARCH INTERESTS: I'm an experimental social psychologist. I study social cognition with a focus on temporal contexts. I'm interested in how people's interpretations of change over time influence their cognition, emotion, and behavior.
Here in the Change Lab, we use this lens of time and change to understand problems like:
-
When & why people mismanage enjoyment (e.g., we find that people often fail to realize that the old and boring can be reignited in new contexts—hedonic adaptation isn't as grim as assumed); for a review of this line of research, click here.
-
When & why people mismanage progress (e.g., we find that people often get stuck on declines and fail to see positive turnarounds); for a review of this line of research, click here.
-
When & why people mismanage impressions (e.g., we find that people often fail to consider how their present actions might "age"); for a review of this line of research, click here.
