Integrating cognitive and emotion paradigms to address the paradox of aging.

Thirty years ago, the subfields of emotion and cognition operated relatively independently and the associated science reflected the tacit view that they were distinct constructs. Today, questions about the integration of cognition and emotion are among the most interesting questions in the field. I offer a personal view of the key changes that fuelled this shift over time and describe research from my group that unfolded in parallel and led to the identification of the positivity effect.
