Unit VI - Learning Flashcards
What is learning?
the process of acquiring through experience new and relatively ENDURING information or behaviors
What are some ways we learn?
COCO
Classical conditioning
Operant conditioning
Cognitive learning
Observational learning
Classical conditioning
learn to expect & prepare for SIGNIFICANT events (pain or food)
associate 2 STIMULI
ANTICIPATE events
Operant conditioning
learn to REPEAT acts that bring rewards/ AVOID acts with unwanted results
associate RESPONSE & CONSEQUENCE
Observational learning
learn by OBSERVING events & people
Cognitive learning
learn things we have neither EXPERIENCED/OBSERVED
Associative learning
Learning to ASSOCIATE an event with another
May be 2 STIMULI or RESPONSE & CONSEQUENCE
positive/negative
How do positive associations factor in learning?
Connect positive events when they occur in sequence
Positive association example
Hang out with new group of classmates for lunch- positive time
Next lunch- associate them with fun/positivity
How do negative associations factor in learning?
Connect negative events when they occur in sequence
Negative association example
Put hand on stove-> get burned
Next time-associate stove with pain
What are the two types of associative learning?
Classical
Operant
How do associations lead to habits?
Learned associations also feed our habitual behaviors.
Eating popcorn at movie theater
How do associations lead to habituation
1 -Sea slug-disturbed by squirt of water Continual squirt--> habituation 2- Slug- shock after squirt Protective response increases Associate squirt with shock
What is habituation?
repeated stimulation produces waning responsiveness.
Habituation v. Sensory adaptation
1- type of LEARNING/ permanent- reduced response due to REPEATED exposure
2-PERCEPTUAL phenomenon- brain STOPS recognizing CONSTANT stimulus
What is a stimulus?
any event or situation that evokes a response
What is a response?
the behavior that follows the stimulus
How is classical conditioning defined?
type of associative learning that involves learned INVOLUNTARY responses.
Involuntary response example
salivation, blinking, sweating, cringing, reactions to strong emotions
How does classical conditioning occur?
STIMULUS 1 - lightning STIMULUS 2 - thunder RESPONSE - startled reaction associate thunder with lightning REPETITION STIMULUS - lightning RESPONSE - startled reaction
How is operant conditioning defined?
associate a response (our VOLUNTARY behavior) and its consequence
Operant behaviors
behavior that operates
on the environment,
producing
consequences
How does operant conditioning occur?
RESPONSE : BEING POLITE
CONSEQUENCE : TREAT
Voluntary REPETITION
behavior STRENGTHENED
Respondent behaviors
behavior that occurs
as an automatic
response to
some stimulus
Do classical and operant conditioning work together?
YES
Cattle ranch
CLASSICAL- cows associate beep with arrival of food
OPERANT- hustling to food trough associated with pleasure of eating
What is behaviorism’s view of learning?
Psychology’s “goal is the prediction and control of behavior
Who was Ivan Pavlov?
Influenced Watson
Both believed the basic laws of learning were the same for all animals
What did Ivan Pavlov contribute to the field of psychology?
spent two decades studying dogs’ digestive system and earned
the Nobel Prize.
experimented with classical conditioning
Pavlov’s dog experiment
Before conditioning
Unconditioned STIMULUS: food in mouth
Unconditioned RESPONSE: salivation
Neutral STIMULUS: tone from bell
NO RESPONSE
Pavlov’s dog experiment
During conditioning
NS (bell) + US (food in mouth)
UR: salivation
REPETITION
Pavlov’s dog experiment
After conditioning
Conditioned STIMULUS: tone from bell
Conditioned RESPONSE:
salivation
What is acquisition?
in CLASSICAL- initial stage-link NS and US- NS trigger conditioned response
in OPERANT- strengthening of reinforced response/ decreasing of punished response
Can onion breath be attractive?
It can be conditioned to be
How does classical conditioning support reproduction?
Conditioning helps an animal survive and reproduce—by RESPONDING to CUES that help it gain food, avoid dangers, locate mates, and produce offspring
What is higher-order conditioning?
procedure in classical conditioning in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus
Higher-order conditioning example
Animal learned tone predicts food
Learn light predicts tone
Therefore, respond to light
How does extinction occur?
when an unconditioned stimulus (US) does not follow a conditioned
stimulus (CS)
What is spontaneous recovery?
the reappearance, after a pause, of an extinguished conditioned response
Extinct occurs ______ spontaneous recovery
before
What is is generalization?
tendency, once a response has been conditioned,
for stimuli similar to the conditioned stimulus to elicit similar responses
Generalization example
Salivate to tone
Playing note on flute may cause salivation
How did Pavlov demonstrate generalization?
Conditioned salivation to stimulation of thigh
Closer a stimulated spot was to thigh, stronger salivation
What is discrimination?
the learned ability to distinguish between a conditioned stimulus and similar stimuli that
do not signal an unconditioned stimulus
Discrimination example
Food(US) after bell(CS) but not tuning fork
Dog learn to discriminate between sounds and only drool(CR) to bell
Why does Pavlov’s work remain so important?
significant psychological phenomena can be studied OBJECTIVELY
classical conditioning is a BASIC form of learning
that applies to ALL species.
What have been some applications of Pavlov’s work to human health and well-being?
former drug users- CRAVING when in drug-using context
people struggling with weight- CONDITIONED to eat food keeping them in poor health
Taste accompanies drug influence immune response, taste PRODUCE response by itself
How did Watson apply Pavlov’s principles to learned fears?
human emotions and behaviors, though biologically influenced, are mainly a bundle of CONDITIONED responses.
Little Albert experiment
Watson & Rayner caused Albert to associate loud sounds with rats
Albert scared of rats after REPETITION
Generalized fear to dog, rabbit, sealskin coat
Classical conditioning is __________ (________) behavior, while operant conditioning is __________
(_______) behavior.
involuntary
respondent
voluntary
operant
Who was B.F. Skinner?
behaviorism’s most influential and controversial figure
His work elaborated
on the law of effect.
What did Thorndike do?
used a fish reward
to ENTICE cats to find their way out of a puzzle box through a series of maneuvers.
What is the law of effect?
behaviors followed by FAVORABLE consequences
become MORE likely behaviors followed by UNFAVORABLE
consequences become LESS likely
What did Skinner design?
Operant chamber or Skinner box
What is an operant chamber?
contains BAR /KEY an animal can MANIPULATE to obtain food/water reinforcer
recorded RATE of bar pressing/key pecking
How does a Skinner box operate
inside box, rat presses bar for food
outside box, measuring devices record accumulated response
What does the Skinner box allow researchers to investigate?
Animals act out concept of reinforcement
Reinforcement
any event that strengthens
(increases the frequency of) a preceding response
People reinforcement examples
praise
attention
paycheck
Rate reinforcement example
Food
water
Are all reinforcers created equal
NO
Reinforcing to one animal may not be to another
What makes a reinforcer a reinforcer?
A reinforcer increases the likelihood that the behavior will increase
How is behavior shaped through operant conditioning?
SHAPING -operant conditioning procedure in which REINFORCEMENT guides behavior toward closer and closer approximations of desired behavior
How would Skinner shape a rat’s behavior to press a bar to get food?
OBSERVE initial behavior
LURE rat with food towards bar
REQUIRE rat to` actually touch bar to get food
What is a discriminative stimulus?
a stimulus that elicits a response after
association with reinforcement
Discrinative stimulus example
training pigeon to peck at green circle (DS) but not a red one
research on discriminative stimulus training in animals.
Dogs- sniff out landmines/locate ppl
Pigeons- identify new object (ppl, cars, chairs,etc.) /distinguish between Back & Stravinsky
What is positive reinforcement?
Increasing behaviors by presenting POSITIVE reinforcement
any stimulus PRESENTED after a response STRENGTHENS the response
What is negative reinforcement?
increasing behaviors by stopping
or reducing AVERSIVE stimuli
Any stimulus when REMOVED after a response STRENGTHENS the response
Positive reinforcement example
Studying hard to receive an A
Arriving at work on time to receive praise/ pay raise from boss
Negative reinforcement
Taking aspirin to reduce headache
Hitting snooze button to shut off alarm
Negative reinforcement is ___ punishment
NOT
Provides relief
What are primary reinforcers?
innately reinforcing stimuli such as those that satisfy a biological need
What are conditioned/secondary reinforcer?
stimuli that gain their reinforcing power through their learned association with a primary reinforcer
Primary reinforcers examples
Food, pain relief
Conditioned reinforcers examples
Money, good grades, pleasant tone of voice
How does the immediacy of the reinforcement impact behavior?
Some animals will need immediate (within 30 seconds for instance) reinforcement in order to tie the reinforcement to the behavior.
Humans respond to delay ______________ as a point of maturity
