Welcome! I'm a professor teaching Introduction to Psychology (and a few other classes) at St. Charles Community College. I'm interested in the biological basis for behavior, in particular the role of the κ-opioid system in regulating the mood-effects of chronic stress in animal models.

  • Society attacks early, when the individual is helpless.
    • Walden Two (1948), p. 95
  • The strengthening of behavior which results from reinforcement is appropriately called "conditioning". In operant conditioning we "strengthen" an operant in the sense of making a response more probable or, in actual fact, more frequent.
    • Science and Human Behavior (1953).
  • Let men be happy, informed, skillful, well behaved, and productive.
    • Freedom and the control of men (1955/1956). American Scholar, 25(1), 47-65.
  • Education is what survives when what has been learned has been forgotten.
  • The real question is not whether machines think but whether men do. The mystery which surrounds a thinking machine already surrounds a thinking man.
    • Contingencies of Reinforcement: A Theoretical Analysis (1969)
  • We admire people to the extent that we cannot explain what they do, and the word "admire" then means "marvel at."
    • Beyond Freedom and Dignity (1972)
  • A person who has been punished is not thereby simply less inclined to behave in a given way; at best, he learns how to avoid punishment.
    • Beyond Freedom and Dignity (1972)
