Chapter 4:Classical Conditioning:Basic Phenomena and Various Complexities Basic Terms Two Extensions Three Limitations Additional Phenomena
Basic Phenomena acquisition curve
Acquisition • Formation of a learned response to a conditioned stimulus through pairing with an unconditioned stimulus
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 Figure 4.2(p. 131) Hypothetical results illustrating a decline in spontaneous recovery across repeated sessions of extinction.
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
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 • 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
CS+ CS- Discrimination Training
Experimental Neurosis • an experimentally produced disorder in which animals exposed to unpredictable events develop neurotic-like symptoms.
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 • First-order conditioning • Second-order conditioning
Limitations to Classical Conditioning • compound stimulus
Limitations to Classical Conditioning • Overshadowing
Limitations to Classical Conditioning • Blocking
