Emeritus Professor



Professor Emeritage, Department of Psychology (Behavioral Neuroscience), College of Liberal Arts and Sciences



Ph.D., Harvard University, 1969

Research Interests

How do we learn? How do we forget? What motivates us? How do we understand anomalies of motivation, such as tobacco addiction? How do we maintain attention, and why is it hard for some people, such as those diagnosed with ADHD, to do so? How do we perceive the passage of time? How do we discount delayed or probabilistic goods? What is information, and how do we use it? What is a scientific explanation; what must it include, what must it omit? How may we undergird scientific inference with better techniques than NHST? In general, how do we find a resonance between models and data; and how do we tune our theories to amplify that resonance?

Research Interests

Latest interests:  Why do we discount the future hyperbolically?

Why is tobacco addictive, but nicotine not? 

What are adjunctive behaviors?

Is all cognition embodied?

What is Attention Deficit / Hyperactivity Disorder?
