Learning Flashcards
Pavlov
-classical conditioning
Watson
“Blank state”
-we can take anyone and shape them into anything
Classical conditioning
- passive response
- reflexes
- elicited responses
- reinforcement is irrelevant to learning
Principles of classical conditioning
- stimulus substitution
- associative learning
- acquisition
- extinction
- spontaneous recovery
- second-order conditioning
Associative learning
-type of learning?
- type of classical conditioning
- neural stimulus leads to reflexive behavior
- ie pavlov’s dog
Stimulus substitution
-type of conditioning?
- type of classical conditioning
- stimuli associated and can be substituted
Acquisition
- phase of classical conditioning when CS and US are presented together
- ie dog doesn’t realize that food is coming right away
Extinction
- CS alone
- response drops off bc association isnt there
- learning is still there but it’s not at forefront of brain
Spontaneous recovery
-bursts of remembering
Generalization
-CR observed even when CS is a little different than the one used during acquisition
Discrimmination
The capacity to distinguish between similar but distinct stimuli
Generalization and discrimination
-the more you have of 1, the less you have of the other
Unconditioned stimulus
With example
Naturally produced reaction to stimulus
-ie give dog food
Unconditioned response
With example
Reflexive action from unconditioned stimulus
-ie dog salivates in response to food
Conditioned stimulus
With example
Initially neural and produces no reliable response
-ie ringing a bell for dog with food
Conditioned response
With example
Reaction is the same as UR but is produced by CS
- not as strong as UR
- ie dog salivates with buzzer sound
What occurs in brain when stimulus acquires conditioned properties
- generalizes
- discriminates
- extinguishes
Little Albert experiment results
- performed by Watson
- used pavlov’s theory of associative memory to Albert’s learning of fear
- showed that strong emotions can be learned and generalized
Little Albert experiment
-associated mouse with loud noise
-learned to fear mouse
-translated fear to other animals
-US: loud noise
UR: fearful crying
-CS: white rat
CR: fearful crying from rat
Little Albert experiment exemplifies classical conditioning principles
- stimulus substitution: fur coat, monkey, rabbit
- discrimination: if monkey is ok
- extinguish: mouse without noise is ok after time
2 factor theory of learning
- who discovered theory
- main theory
- Mowrer
- theory of avoidance learning
- classical: learn to avoid
- operative: avoiding results in reward, fear continues
- negative reinforcement: taking away something negative (fear)
- reinforcing avoidance behavior
Delay conditioning
- part of classical conditioning
- CS followed by US
- ie tone (CS) followed by puff of air (US) into eye. Response=eye blink; tone eventually elicits eye blink
- tone is on, puff, both end together
Trace conditioning
- example
- part of brain
- same as delay conditioning except tone goes then pause then puff of air (aware of difference between US and CS)
- ie people on vegetative state may process verbal stimuli
- hippocampus
Biological preparedness
- tendency for learning certain kinds of associations over others
- some behaviors are easy to condition, others are not
- classical conditioning works best with stimuli that are biologically relevant to organism
Conditioned emotional response (CER)
- emotionally charges CR elicited by previously neutral stimulus
- ie food, music, sexual interests
- sexual arousal:
- US: erotic imagery; UR: arousal
- CS: shoes; CS: arousal
Drug tolerance and classical conditioning
- conditioned stimuli before drug intake can illicit response that prepares body for drug
- overdose: taking heroin in different location because body is not prepared for it
