Instrumental, operant, contiguity +contingency Flashcards
instrumental and operant conditioning
classical conditioning
Learning associations between stimuli
Ex. a bell meant food was coming
instrumental conditioning
Learning associations between stimuli, response, and outcome, leads to get directed behavior
Ex. brush teeth, no cavities
thorndike puzzle box
Food restricted cats
Goal: escape and food measured latency to escape
Cats learned association between stimulus and response
Association affected by outcome
Rope in box (S) + pulling rope (R) → escape (o)
law of effect
Response to a stimulus followed by a satisfying event strengthened S-R relationship
Ex. pull rope→ food and escape→ less time to escape
Response to a stimulus followed by an annoying event→ Weekend S-R relationship
Ex. pull rope in the box→ shock→ longer time to escape
discrete trial approach
Response is performed once
Behavior of subject terminates trial
Timing of trial determined by the experimenter
free operant approach
Subject is free to respond at any time
May be repeated many times
Timing of responses determined by subject
skinner box - operant
Skinner box measures operant response rate
Ex: number of lever presses for food
Operant responses
Behavior that “operates” on the environment
magazine training (classical conditioning)
How to produce target response
Step 1: magazine training
Classical conditioning- sound of the magazine (food dispenser) is a CS+, followed by a food US that orients organism
Ex. shaking kat kaviar to get cats attention
shaping (instrumental)
Rewarding successive approximations to target behavior by;
1. Reinforcing closer actions to the correct response
2.Not reinforcing early non target responses (only when rat touches bar they get a treat)
Correct steps are preserved
Ex. the rat still rears up to push the bar
shaping familiar response
Must be a variable response
Opening of the beak to eat
Slowly step up criteria
Can bring about super or miniature responses
With training we can modify consummatory behavior
Deich allan andzeigler
Training beak opening in pigeons
Terminology
A response may produce 1 or 2 outcomes
Appetitive stimulus:
Pleasant outcome (getting paid, food, sunshine)
Aversive stimulus:
Negative outcome (yelling, shock, cold)
contingency
something likely to occur bc of something else
Positive contingency:
Response turns on/causes and outcome
A rat can press the lever to get food
Negative contingency
Response turns off/ inhibits an outcome
A rat can turn off a loud noise by pressing the lever
positive reinforcement
Positive contingency between response and appetitive stimulus
Response turns on a good thing
Outcome
Increased responding
Ex
Dog training
Good grades
Working to get paid
punishment
Positive contingency between response and aversive stimulus (response turns on a bad thing)
Outcome: decreased responding
Ex
Ticket for speeding
Cat goes on table gets sprayed
omission
Negative contingency between a response and an appetitive stimulus
Response removes an appetitive stimulus (response removes smth you like)
Outcome: decreased responding
Ex
Swearing leads to loss of TV
Hit bro phone gets taken away
Autoshaping reversal
negative reinforcemnt
Negative contingency between response and aversive stimulus
Response turns off or avoids a bad thing
Outcome: increased responding
Types
Escape: aversive stimulus present at the time of behavior, stopped by response
Cats do smth to avoid smth aversive
Taking advil to get rid of headache
Avoidance: aversive stimulus schedules to happen but is prevented from happening by response - never experience the aversive stimulus its prevented
Putting sunscreen on if you know your going in the sun
Barton bulle and repp
Differential reinforcement of other behaviors
Subjects- students w autism spectrum disorder
Behaviors
Hand flapping- decrease
Omission training
Other behaviors- increase
Positive reinforcement
You drink 4 locos at a party and find its easier to socialize, so u drink it again next time out
Positive reinforcement
U are deathly afraid of clowns after your catastrophic 5th birthday,every time you see one you run and hide
Negative reinforcement
escape
instrumental conditioning foundation
Response
Response- reinforcer - relation
Reinforcer
response
Behavior performed
Conditioned behavior depends upon the response conditioned
Variable vs stereotyped response
Belongingness of response
Behavioral systems
reinforce any–>
stereotype response
reinforce variability–>
variable response
Page and neuringer
Pigeons peck 2 keys 8 times→ food
Control group: any sequence→ food
Variability group: no repeat→ food
Reinforcing variability encourages creativity
