Ch. 8 and 9: Learning And Memory Flashcards
Learning
Relatively permanent change in behavior due to experience
Adaptability
Capacity to learn new behaviors so we can change with our circumstance
Associative learning
Learning that events occur together
Conditioning
Learning associations
Classical conditioning
Association of 2 stimuli to anticipate something
Operant conditioning
Association of our behavior with someone/something else’s response to it
Seeks positive results or the removal of negative ones
Behaviorism
View that psych
- Should be an objective science that
- Studies behavior w/o reference to mental processes
Most agree with 1 but not 2
Unconditioned response
Natural response to unconditioned stimulus (salivation when food is in the mouth)
Unconditioned stimulus
Stimulus that naturally triggers a response
Conditioned response
Learned response to a previously natural stimulus
Conditioned stimulus
Originally irrelevant stimulus that comes to trigger a conditioner response
Acquisition
Associating a neutral stimulus with a natural stimulus so that the neutral stimulus comes to cause a conditioned response
Extinction
Diminishing of a conditioned response when a natural response doesn’t follow a conditioned response
Spontaneous recovery
Reappearance, after a period of time, of an extinguished learned response
Generalization
Tendency, once a response has been learned, for similar stimuli to cause a similar response
Discrimination
Learned ability to distinguish between a learned stimulus and stimuli ha don’t signal a natural response
Expectancy
Awareness of how likely it is that the natural response will occur
Respondent behavior
Occurs as an automatic response to some stimulus
Operant behavior
Operates on the environment, producing consequences
Law of effect
Thorndike’s principle that behaviors followed by favorable consequences become more likely and vice versa
Operant chamber (Skinner box)
Chamber containing a bar or key that an animal can manipulate to obtain a food reinforcer
Shaping
Procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
Successive approximations
Rewards responses that are ever-closer to the final desired behavior and ignore all other responses
Discriminative stimulus
Signals that a response will be reinforced
Reinforcer
Any event that strengthens the behavior it follows
Positive reinforcement
Increasing behaviors by presenting a positive stimuli
Negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli
Takes a way an unwanted stimulus
Primary reinforcer
Innately reinforcing stimulus (such as one that satisfies a biological need)
Conditioned reinforcers (secondary reinforcers)
Stimulus that gains its reinforcing power through its association with a primary reinforcer
Continuous reinforcement
Reinforcing the desired response every time it occurs
Partial (intermittent) reinforcement
Reinforcing a response only part of the time
Results in slower acquisition but creates resistance to extrinction
Fixed-ratio schedule
Reinforcement schedule that reinforcers a response only after a specified number of responses
Variable-ratio schedule
Reinforcement schedule that reinforces a response after an unpredictable number of responses
Fixed-interval schedule
Reinforces a response only after a specified time has elapsed
