0.1 Behavioral view of learning  (Page 9/10)

Comparing operant conditioning and classical conditioning: Operant conditioning is made more complicated, but also more realistic, by many of the same concepts as used in classical conditioning. In most cases, however, the additional concepts have slightly different meanings in each model of learning. Since this circumstance can make the terms confusing, let me explain the differences for three major concepts used in both models—extinction, generalization, and discrimination. Then I will comment on two additional concepts—schedules of reinforcement and cues—that are sometimes also used in talking about both forms of conditioning, but that are important primarily for understanding operant conditioning.

In both classical and operant conditioning, extinction refers to the disappearance of “something”. In operant conditioning, what disappears is the operant behavior because of a lack of reinforcement. A student who stops receiving gold stars or compliments for prolific reading of library books, for example, may extinguish (i.e. decrease or stop) book-reading behavior. (The student may also experience spontaneous recovery , which means the previously extinguished behavior reappears.) In classical conditioning, on the other hand, what disappears is association between the conditioned stimulus (the CS) and the conditioned response (CR). If you stop smiling at a student, then the student may extinguish her association between you and her pleasurable response to your smile, or between your classroom and the student’s pleasurable response to your smile.

In both forms of conditioning, generalization means that something “extra” gets conditioned if it is somehow similar to “something”. In operant conditioning, the extra conditioning is to behaviors similar to the original operant . If getting gold stars results in my reading more library books, then I may generalize this behavior to other similar activities, such as reading the newspaper, even if the activity is not reinforced directly. In classical conditioning, however, the extra conditioning refers to stimuli similar to the original conditioned stimulus. If I am a student and I respond happily to my teacher’s smiles, then I may find myself responding happily to other people (like my other teachers) to some extent, even if they do not smile at me. Generalization is a lot like the concept of transfer that I discussed early in this chapter, in that it is about extending prior learning to new situations or contexts. From the perspective of operant conditioning, though, what is being extended (or “transferred” or generalized) is a behavior, not knowledge or skill.
