The research program employs learning, pharmacological, and
physiological techniques to investigate the mechanisms underlying
appetitive (e.g., hunger) and aversive (e.g., fear, stress) motivational
Current interests focus on three questions: (1) What physiological events give rise to the internal stimulus consequences of motivational states? (2) How is learning about these internal stimuli involved in the control of behavior? (3) What mechanisms underlie learning about internal cues?
