Organism is black box: shun references to internal states (emotions, thoughts, focus only on observable behaviors (the facts) Classical conditioning: focus on associations linked to : Involuntary behaviors (e. g. reflexes: key reserarcher: pavlov. A stimulus (ucs) automatically triggers an involuntary response (ucr). During conditioning: a neutral stimulus (ns) is presented with the ucs, comes to automatically trigger a conditioned response (cr, the ns becomes a conditioned stimulus (cs) All we need to know in order to describe and explain behavior is this: actions followed by outcomes are likely to recur, and actions followed by bad outcomes are less likely to recur. Increasing a behavior by removing an aversive stimulus when a behavior occurs. Punishment: decreasing a behavior by administering an aversive stimulus following a behavior, or by removing a positive stimulus. Extinction: decreasing a behavior by not rewarding it.
