Basic Phenomena

acquisition curve


Acquisition l.jpg

Acquisition

  • Formation of a learned response to a conditioned stimulus through pairing with an unconditioned stimulus


Extinction l.jpg

Extinction

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


Spontaneous recovery l.jpg

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 l.jpg

Basic Phenomena

  • disinhibition

    • the sudden recovery of a response during an extinction procedure when a novel stimulus is introduced.


Generalization discrimination l.jpg

Generalization & Discrimination

  • Generalization

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


Generalization discrimination9 l.jpg

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 l.jpg

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 l.jpg

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 conditioning15 l.jpg

Extensions to Classical Conditioning

  • Sensory Preconditioning

    • A stimulus associated with one CS can also become a CS

      • First-order conditioning

      • Second-order conditioning


Limitations to classical conditioning l.jpg

Limitations to Classical Conditioning
