Unit 5 Pt 1: Learning And Classical Conditioning Flashcards
Learning
A relatively permanent change in organism’s behavior due to experience (nurture)
Most learning is in the
Associative areas
3 types of learning
Classical conditioning
Operant conditioning
Observational learning
Classical conditioning
Making a connection between a neutral and unconditioned stimulus
Operant conditioning
Making a connection between behavior and consequences
Observational learning
Learning by watching
All living things learn through
Association
Father of behaviorism
John Watson
Behaviorism focused on making psychology
An objective science
Watson focused on
External behavior within specific external situations
What did Watson believe
Nurture was more important than nature
Classical conditioning aka
Pavlovian conditioning
Unconditioned
It is unlearned and comes naturally/reflexively
Unconditioned example
Salivating when presented with food
Conditioned
Learned and response doesn’t come naturally
Conditioned example
Getting up when school bell rings
Response
External behavior like salivating
Stimulus
External thing that may cause a behavior like a bell or food
Stimulus creates
Response
Father of classical conditioning
Ivan Pavlov
Ivan Pavlov
Russian physician/neurophysiologist
Studies digestive enzymes in dogs when accidentally realized importance of associative learning
Classical conditioning
An organism comes to associate stimuli
Like tone and food
Classical conditioning begins
With a reflex which is unconditioned (unlearned)
Unconditioned stimulus
Effective stimulus that unconditionally-automatically and naturally triggers a response
Unconditioned response
Unlearned, naturally occurring automatic response to the conditioned stimulus
Conditioned stimulus
Previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
Conditioned response
Learned response to a previously neutral conditioned stimulus
Acquisition
Initial stage of learning, during which a response is established and gradually strengthened.
Acquisition is when
A previously neutral stimulus causes conditioned response
Extinction
Diminishing of a conditioned response.
Example: the bell no longer makes the dog salivate
How would you make extinction occur?
Stop pairing UCS (food) with CS (bell)
Spontaneous recovery
Referred to reappearance, after a rest period, of an extinguished condition.
Decides to do it again
Generalization
Tendency of a stimuli similar to CS to evoke similar responses
Generalization example
Doesn’t have to be the same tone to make dog’s salivate…they generalize
Generalization and discrimination describe __________, not thoughts
behavior
Discrimination
Ability to distinguish between a CS and other stimuli that don’t signal an UCS.
Discrimination example
Dogs wouldn’t salivate to a whistle since it was too different from the tone
Cute baby Albert case
Every time he got near the white furry rat the experimenters made a scary sound so ever since then he got scared.
He even got scared of rabbits and everything that’s white and furry he got scared
Cute Baby Albert: UCS
The sound
Cute Baby Albert: UCR
Fear from the sound
Cute Baby Albert: neutral stimulus
White rat
Cute Baby Albert: CS
White rat
Cute Baby Albert: CR
Fear of the white rat
Cute Baby Albert: generalization
White rats, fur, white furry things
Higher order conditioning AKA
Second order conditioning
Higher order conditioning
It occurs after organism has already learned a response to a conditioned stimulus
Higher order conditioning:
You pair a new neutral stimulus before the conditioned stimulus which leads to
A new response to the new neutral stimulus which is usually weaker
Criticism of old behaviorist ignore
Cognition
Old school behaviorists ignored cognition
Studies proved that subjects attitudes did mater when attempting to create conditioned response in them
Modern psychologists often add cognitive explanation to
Conditioning
Robert Rescorla Argued that learning during classical conditioning was impacted
by how reliably the CS (tone) PREDICTED the UCS (food)
Rescorla argued that
The reliability of the signal created an EXPECTATION which led to a conditioned response
Expectation: cognitive element
Old school behaviorists ignored biological predisposition:
Taste aversion studies
Showed that an animal’s capacity for conditioning is constrained by biology. Conditioning occurs easier with some stimuli than others.
Garcia’s taste aversion studies with rats
Experiment where rats got exposed to sights, sounds, and tastes and later gave radiation or drugs that made them nauseous and vomit.
Hours later the rats avoided taste of flavor but not sight and sound.
Taste aversion studies violated
Behaviorists principle that any stimulus could serve as CS
Taste aversion studies show that nature prepares
The members of each species to learn those things crucial to their environment
Taste aversion studies are expectations to classical conditioning rules
UCS does not always have to follow CS immediately
Aversion
To avoid something
Real world classical conditioning example of crack cocaine
Users feel craving wen they are near the same people or place where the took drugs. So rehab counselors advice them to leave places and make new friends
Real world classical conditioning example of alcohol
Alcohol with drug that makes you vomit will make you quit drinking
