chap 7-8 Flashcards
what is learning?
process of acquiring through new experience new information or behaviors
How do we learn: Associative learning
-certain events that occur together (classical conditioning)
-stimuli that are not controlled are associated
-response becomes automatic (respondent behavior)
How do we learn: consequences
-association between a response and a consequence is learned (operant behavior)
Classical conditioning
-basic learning form
-type of learning in which one learns to link two or more stimuli and anticipate events
-response becomes automatic
operant behavior
-behavior that operates on the environment, producing a consequence
-consequence can be good or bad
Pavlov
-founded classical conditioning
-demonstrate associative learning via salivary conditioning in dogs
watson
-“father of behaviorism”
-believed that theoretical goal of the science of psychology is prediction and control of behavior
conditioning experiment
-unconditioned stimulus (food) produces an unconditioned response (salvitation)
-neutral stimulus (tone) produces no response
-Unconditioned stimulus (food) is presented after the neutral stimulus (tone)
-unconditioned stimulus (food) continues to produce a unconditioned response (salivation)
-Neutral stimulus (now conditioned stimulus: tone) now produces a conditioned response (salivation)
-neutral stimulus becomes the conditioned stimulus
-unconditioned response becomes the conditioned response
neutral stimulus
-stimulus that naturally/automatically triggers an unconditioned response
-elicits no response before conditioning
conditioned response
a learned response to a previously neutral but now conditioned stimulus
conditioned stimulus
originally neutral stimulus that after association with an unconditioned stimulus comes to trigger a conditioned response
unconditioned response
unlearned naturally occurring response to an unconditioned stimulus
unconditioned stimulus
stimulus that naturally/automatically triggers an unconditioned response
Classical conditioning: Acquisition
-when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response
Classical conditioning: higher-order conditioning
-also called second order conditioning
procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second conditioned stimulus
classical conditioning: extinction
-diminishing of a conditioned response
-occurs in classical conditioning when an unconditioned stimulus does not follow a conditioned stimulus
classical conditioning: spontaneous recovery
reappearance of an extinguished conditioned response
Classical conditioning: Generalization
tendency once a response has been conditioned for a stimuli similar to the conditioned stimulus to elicit similar response
ex: scared of all bugs
Classical conditioning: Discrimination
learned ability to distinguish between a conditioned stimulus and other irrelevant stimuli
ex: scared of just bees
operant conditioning
type of learning in which behavior becomes more likely to recur if followed by a reinforcer or less likely if punisher
Law of effect
-Edward L. Thorndike
-behaviors followed by favorable consequences become more likely while unfavorable consequences are more unlikely
-operant conditioning
Operant chamber (skinner box)
-B.F. Skinner
-chamber containing a bar or key that an animal can manipulate to obtain a food or water reinforcer
-attached devices record the animal’s rate of bar pressing
Operant conditioning: reinforcement
any event that strengthens a preceding response; makes a behavior more likely to occur
Operant conditioning: shaping
reinforcers gradually guide behavior toward closer and closer approximations of the desired behavior
Operant conditioning: positive reinforcement
-increases behaviors by presenting positive/pleasurable forces
-any stimulus that, when presented after a response, strengthens the response
- means giving
Operant conditioning: negative response
-increases behaviors by stopping or reducing negative stimuli
-any stimulus that, when removed after a response, strengthens the response
-ex: using exercise to remove stress
-ex: car dinging to put on seatbelt
Operant conditioning: primary
-unlearned, innately reinforcing stimuli
-satisfies biological needs
-ex: hugs, candy
Operant conditioning: conditioned (secondary)
gains power through association with primary reinforcer
-ex: money
Operant conditioning: immediate
occurs immediately after a behavior
Operant conditioning: delayed
involves time delay between desired response and delivery of reward
-wont associate action with punishment/reward
Operant conditioning: reinforcement schedule
a pattern defines how often a desired response will be reinforced
Operant conditioning: continuous reinforcement schedule
reinforces the desired response every time it occurs
Operant conditioning: partial (intermittent reinforcement)
-reinforces a response only part of the time
-results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement
Schedules of Reinforcement: Fixed Ratio
reinforces a response only after a specified number of responses
-very high rate of responding
-extinction happens fast
-immediate effect
-ex: rat gets food every third time it presses the lever
Schedules of Reinforcement: variable ratio
-reinforces a response after an unpredictable number of responses
-random
-extinction takes longer
- gambling, fishing, very hard to extinguish because of unpredictability
-ex: hitting a jackpot sometimes on the slot machine
Schedules of Reinforcement: Fixed Interval
-reinforces a response only after a specified time has elapsed
-rapid responses at end interval
-ex: getting paid weekly no matter how much work is done
Schedules of Reinforcement: Variable Interval
-reinforces a response at unpredictable time intervals
-produces slow and steady responding
-least likely to extinct
-ex: checking phone all day, sometimes getting a text
Operant conditioning: punishment
-admininters an undesirable consequence or withdraws something desirable in an attempt to decrease the frequency of a behavior
Operant conditioning: positive punishment
-administer an aversive stimulus
-presenting a negative consequence after an undesired behavior is exhibited, making the behavior less likely to happen in the future
Operant conditioning: negative punishment
-withdrawing a rewarding stimulus
-taking away something good
4 major drawback of physical punishment
1) punished behavior is suppressed, not forgotten
2) punishment teaches discrimination among situations
3) punishment can teach fear
4) physical punishment may increase aggression by modeling aggression as a way to cope with problems (must be immediate; punish in the moment; punishment needs to match the crime)
Skinner’s Legacy: Applications of Operant Conditioning
-at school: computer and adaptive learning software used in teaching and learning
-in sports: behavioral methods implemented in shaping behavior in athletic performance
-at work: rewards successfully used to increase productivity
-in parenting: basic rules of shaping used in parenting
limits on classical conditioning
-animals and humans seem biologically prepared to learn some associations rather than others
-conditioning is stronger when the conditioned stimulus is ecologically relevant
-genetic predisposition to associate a conditioned stimulus with an unconditioned stimulus that follows predictably and immediately is adaptive
