Basic Phenomena

Extinction

• Elimination or weakening of a learned, conditioned response by removal of the unconditioned stimulus when the conditioned stimulus is present

Spontaneous Recovery

• Re-emergence of an extinguished conditioned response after a rest period

Basic Phenomena

• disinhibition

• the sudden recovery of a response during

an extinction procedure when a novel

stimulus is introduced.

Generalization & Discrimination

• Generalization
  • The tendency to respond to a stimulus that is similar to the conditioned stimulus

Watson & Little Albert

• Albert conditioned to fear a white laboratory rat - Each time he reached for the rat, Watson made a loud clanging noise right behind Albert
• Albert’s fear generalized to anything white and furry - Including rabbits and Santa Claus

Extensions to Classical

Conditioning

• Higher-Order Conditioning
  • A stimulus associated with one CS can also become a CS - First-order conditioning - Second-order conditioning

Limitations to Classical

Conditioning

• compound stimulus
