UNIT 3 CHAP 6 Flashcards
learning
enduring change in the way an organism responds based on experience
Maturation
change resulting from biological development
classic conditioning
neutral stimulus is associated with a natural response
Unconditioned stimulus (UCS)
stimulus that automatically
and naturally triggers a
response (dog biscuit)
unconditioned response (UCR)
unlearned, naturally
occurring automatic
response to the
unconditioned stimulus (drool after biscuit is placed in mouth)
conditioned stimulus (CS)
previously neutral stimulus
that, after association with an
unconditioned stimulus, comes
to trigger a conditioned
response (a bell)
conditioned response (CR)
learned response to a
previously neutral conditioned
stimulus (drools before biscuit is inside mouth)
Garcia effect
If a flavor is followed by an illness
experience, animals will not
consume the flavor in the future
(CS+UCS–>UCR) then (CS–>CR)
stimulus generalization
If a response is
conditioned to one
stimulus, the organism
may also respond to a
similar stimulus
Stimulus discrimination
Occurs when original CS
predicts CR, but similar
stimuli don’t
extinction
CS no longer triggers CR bc CS ceases to predict UCS
Spontaneous recovery
reappearance, after a
rest period, of an
extinguished CR
- temporary small return of CR
-extinction NOT forgetting
classical conditioning (best vs worst)
Best: CS precedes UCS
worst: UCS precedes CS
factors that impact speed of acquisition
- number of pairings
- strength of CS
-timing of UCS and CS
Operant conditioning
type of learning in which behavior (Bx) is strengthened if
followed by reinforcement or diminished if followed by
punishment
Bx–>consequence–>Bx inc or dec
