TEACHING EXPERIENCE

I taught undergraduate and graduate classes from 1967-2010 among the following courses.

  • Introductory Psychology (Undergraduate)
  • Experimental Psychology (U)
  • History of Psychology (U, Graduate)
  • Biological Foundations of Behavior (U, G)
  • Neuroanatomy for Behavioral Scientists (G)
  • Comparative Psychology (U)
  • Seminar: Physiological Bases of Behavior (G)
  • Seminar: Neural Correlates of Learning (G)
  • Seminar: Evolution of the Brain and Intelligence (U, G)
  • Seminar: Cognitive Processes in Animals (G)
  • Seminar: Evolution of Consciousness (U)
  • Seminar: Comparative Neuroanatomy for Behavioral Scientists (G)

I received the Psi Chi Award for Graduate Teaching (the department’s highest annual award for graduate teaching) in 1985 and 2001.  Given what I taught, 1985 was for Neuroanatomy for Behavioral Scientists and 2001 was for History of Psychology.
