Learning and Consciousness Flashcards
learning
a relatively permanent change in behavior based on experience
allows organisms to adapt
Ivan Pavlov
Russian behavioralist in the early 1900s [operated under a different standard of ethical principles]
when two events become associated together
automatic
involuntary learning
neutral stimulus
doesn’t do anything by itself
word can
sound of tuning fork
red light in pigeon ex
Unconditioned stimulus
squirting water
meat
female pigeon
what the organism naturally, reflexively responds to
what caused response without need for learning
conditioned stimulus
starts out as neutral stimulus because it orginially elicits no response but then it becomes learned after many pairings
what do they respond to that they did not respond to before
can
tuning fork
red light
unconditioned response
natural, unlearned reflexive response to UCS
salivating
flinching
arousal
conditioned response
the new learned response to the conditioned stimulus
salivate to bell
flinch at can
arousal at light
contiguity
PAVLOV PAVLOV PAVLOV PAVLOV two events happen together association same place and same time almost coincidence
Contingency
Rescorla 1960s
one event predicts the other
not just association
most accepted
acquisition
learn a certain behavior
flinch at word can
Cs —> CR
CS leads to CR/ brings out CR
Extinction
no longer doing behavior behavior goes away dissociate the 2 don't flinch at word can any more Murphy's kid and dogs- no longer afraid
Stimulus Discrimination
Knowing different between CS and other stimuli
didn’t flinch at ban/fan
Stimulus Generalization
Flinch at ban/fan
generalized to other stimuli
applied learning to other
Higher order conditioning
2nd order conditioning
salivate to new, never seen stimulus (blue square) when presented with the bell
pair new stimulus with CS (original UCS not a part of it)
difficult to get to the third step because it is so far removed
blocking
learning doesn’t happen
something blocks the learning
first CS blocks or slows learning of a new CS
kitty used to electric can opener noise, harder to learn sound of manual
Taste Aversion
Not all stimuli are netural
taste aversion keeps it from being neutral
most mammals have VERY strong taste aversions
rats and water
spontaneous recovery
behavior spontaneously comes back after going extinct
flinch at the wird can after school
Garcia
the main guy behind taste aversion
1960s
All stimuli are not neutral
Aversion therapy
using negative CR ti break bad habits (bitter nail polish)
anatubuse- drug for alcoholics- get sick while drinking alcohol,
Little Albert
Most babies are not afraid of things but they have the capacity to be NS rat UCS- loud noise UCR- fear CS- rat Cr fear
Conditioned emotional response
phobias and superstitions
stimulus causes conditioned response of an emotion
fear is most common
operant conditioning
learning based on consequences
subjects have more control over their learning (voluntary(
actions(conditioned responses) can be new
based on choices
must wait for behavior to occur naturally and reward given
Ed Thorndike
Earliest instrumental(operant)
Conditioning researcher
Puzzle box- figure out how to get out (cats)
Puzzle box
Ed Thorndike’s box where animals needed to figure out how to get out (cats)
Law of Effect
Behavior depends on its consequences Pleasant consequences- more likely to repeat behaviour not rewarded tends to die out antecedent behavior consequences
B.F. Skinner
ENhanced the work done by Thorndike
Designed SKinner boxes (operant chambers)
used reinforcements= reward for behaviors
Positive Reinforcement
a pleasurable consequence for a desired behavior
seal given fish
Negative Reinforcement
an unpleasant condition is removed when a desired behavior is completed
study to stay on the team
aspirin avoid pain
positive punishment
an undesirable behavior is followed by an unpleasant consequence
pull on leash
an F
Omission Training (negative punishment)
discourages a behavior by taking away something desirable
stay out, lose car
Primary reinforcers
never needed to learn it was a reinforcer food water affection a smile shelter
Secondary reinforcer
learn it is good a reward that needed to be learned sticker gold star grades money clothing
chimp-o-mat experiment
primary reinforcers(food/grapes) work on chimps, do secondary(gold tokens)?
got them to do laundry with grapes then moved to tokens
stole tokens and fought for them
prostitution
Premack Principle
CHimps 1960s
Explain how and why reinforcers work
1) a more liked stimulus can be used to reinforce a less liked one
2) personal preference matters (sam and Pat, Sam hates chocolate, needs crackers and cheese)
Overjustification
=giving reinforcers for behaviors people already do or reinforcing them can lead to problems
criticism of conditioning
criticism of using reinforcers to get people to do things they already like
ALFIE KOHN
can’t be sure behavior will continue/ lose love of the activity
ducks in the park
reading with pizza parties/reading logs
Agonists
Enhance neurotransmitters
Antagonists
Inhibit meurotransmitters
Tolerance
Need more drug for same effect
Physical dependence
Cravings and need for drug
Withdrawal
The painful side effects of stopping drug use
Depressants
Slow nervous system activity
