Biography

I am director of the DU Motivation, Affect, & Cognition (MAC) Lab, investigating the mechanisms by which motivation and affect influence human cognition and behavior. How we feel and what we want play a critical role in driving our thoughts, actions, and memories; our lab aims to characterize the psychological and neural processes that underlie these relationships.

With a specific focus on cognitive control -- flexible maintenance, updating, and inhibition functions enabling controlled performance -- and episodic memory -- detail-rich, long-term memory representations of specific events, we investigate the impact of motivational contexts on cognitive processes supporting adaptive human behavior.

The MAC Lab uses a combination of behavioral paradigms, psychophysiology (including facial EMG and pupillometry), functional neuroimaging (fMRI), and video analysis of behavior in naturalistic environments to investigate these effects.

Specific topics within our research program include:

  • how motivated cognitive control and learning might differ depending on goal state (for example, approach vs. avoidance)
  • how motivation might be comprised of dissociable components (i.e., affective experience and goal drive) making separate contributions to goal-directed behavior
  • motivated cognition in laboratory versus naturalistic environments
  • the role of timing and individual differences in modulating these relationships

This research has important implications for understanding motivation, affect and cognition in healthy individuals as well as in psychopathology, where these processes are often disrupted.
