Basic Phenomena

acquisition curve

acquisition
Acquisition
  • Formation of a learned response to a conditioned stimulus through pairing with an unconditioned stimulus
extinction
Extinction
  • Elimination or weakening of a learned, conditioned response by removal of the unconditioned stimulus when the conditioned stimulus is present
spontaneous recovery
Spontaneous Recovery
  • Re-emergence of an extinguished conditioned response after a rest period

Basic Phenomena

Figure 4.2(p. 131)

Hypothetical results illustrating a decline in spontaneous recovery

across repeated sessions of extinction.

basic phenomena
Basic Phenomena
  • disinhibition
    • the sudden recovery of a response during an extinction procedure when a novel stimulus is introduced.
generalization discrimination
Generalization & Discrimination
  • Generalization
    • The tendency to respond to a stimulus that is similar to the conditioned stimulus
generalization discrimination9
Generalization & Discrimination
  • Discrimination
    • The ability to distinguish between different stimuli, tendency for a response to be elicited by one stimulus and not another (sometimes similar) stimulus
watson little albert
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

Experimental Neurosis

  • an experimentally produced disorder in which animals exposed to unpredictable events develop neurotic-like symptoms.
extensions to classical conditioning
Extensions to Classical Conditioning
  • Higher-Order Conditioning
    • A stimulus associated with one CS can also become a CS
      • First-order conditioning
      • Second-order conditioning

Extensions to Classical Conditioning
  • Sensory Preconditioning
    • A stimulus associated with one CS can also become a CS
