Learning
z refers to an enduring change in the way an organism responds based on its experience
distinct from drug effects, fatigue or illness
z three assumptions of learning theories
responses are learned rather than innate
learning is adaptive
our experiments can uncover the laws of learning
Classical Conditioning
z Pavlov noted that reflexive salivation
in dogs could be elicited by stimuli
associated with feeding
z Reflex is response that is reliably
elicited by a stimulus
Food elicits salivation
Air puff elicits eye blink
z Reflexive stimulus and response are
unconditioned
z Neutral stimulus is referred to as the
conditioned stimulus (CS)
z CS is paired with the UCS over many
trials
z Which eventually comes to elicit a conditioned response
CR Æ resembles the UCR
Acquisition and Extinction
z Acquisition of classical conditioning
z repeated pairings of CS and UCS
z Extinction refers to the weakening of conditioning evident when the CS is presented
repeatedly without the UCS
z Spontaneous Recovery: refers to the reemergence of a previously extinguished CR
Stimulus Generalization and Discrimination
z Stimulus Generalization occurs when an organism that has learned a response to a
specific stimulus responds in the same way to new stimuli that are similar to the original
