Exam 5 Flashcards
Learning
A relatively permanent change in behavior and knowledge that occurs as a result of prior experience
Behaviorism
Explained solely in terms of directly observable events
Avoids organism’s unobservable mental state
Only interested in Stimulus-Response
Association Learning
People learn by making connections or bonds
Classical Conditioning
Making an association between two stimuli (by pairing them) such that one stimulus comes to elicit a response that originally was elicited by the other stimulus
Ivan Pavlov
Russian Physiologist by training
Found dogs salivated or drooled when no food was present
Basic Terminology of Classical Conditioning: Neutral Stimulus: NS
A stimulus that does not naturally elicit a (the desired) response in an organism
Wished trigger
Basic Terminology of Classical Conditioning: Unconditioned Stimulus: UCS
Not learned stimulus
A stimulus that elicits a reflexive or innate response (the UCR) without prior learning (conditioning)
Natural trigger
Basic Terminology of Classical Conditioning: Unconditioned Response: UCR
Unlearned (not learned) response
A reflexive or innate response that is elicited by a stimulus (the UCS) without prior learning
Natural response to natural trigger
Basic Terminology of Classical Conditioning: Conditioned Stimulus: CS
A previously neutral stimulus that, through association with a UCS, comes to elicit a conditioned response similar to the original UCR
Learned trigger
Basic Terminology of Classical Conditioning: Conditioned Response: CR
A response elicited by a conditioned stimulus
Learned response to learned trigger
Additional Terminology of Classical Conditioning: Acquisition
The period during which a response is being learned
Measured in trials
CC: Acquisition: Trial
Every time the NS and UCS are presented together
CC: Acquisition: Temporal Pairings
The interval pairing of the NS-UCS also affects conditioning (the way in which you present the NS and UCS and how much time elapses between presentation)
Forward, Simultaneous, Backward
Forward Classical Conditioning/Forward Temporal Pairing
NS comes before the UCS
Best one (makes learning easier)
Short Delay
Trace
Short Delay - Forward Classical Conditioning
You present the NS, wait a fraction of a second or so, and then while the NS is still present, you present the UCS (delayed presentation of the UCS but the NS is still present when it is presented)
Trace - Forward Classical Conditioning
Your present the NS and then remove it, you wait a fraction of a second or so and then present the UCS (delayed presentation of the UCS while the NS is no longer present)
Simultaneous Conditioning/Simultaneous Temporal Pairing
Presenting the NS and the UCS at the same time
Backward Conditioning/Backward Temporal Pairing
Presenting the UCS before the NS
Not very effective
Classical Conditioning is the strongest when…
There are repeated pairings of NS and UCS
The inter-stimulus interval is short
Inter-Stimulus Interval
The time between NS and UCS
Extinction
A process in which the CS is presented repeatedly in the absence of the UCS, causing the CR to weaken and eventually disappear (the CR will go away)
Spontaneous Recovery
The reappearance of a previously extinguished CR after a rest period and without new learning trials (have to acknowledge that the CR is no longer linked to the CS)
Stimulus Generalization
Any stimuli similar to the initial CS will elicit a CR
Ex. Salivation may be elicited by a bell or a piano tone
Stimulus Discrimination
A CR occurs in the presence of one stimulus but not in the present of others (other stimuli) (makes a distinction between the stimuli)
Ex. Salivation may not be elicited by a whistle
Higher-Order Conditioning
Occurs when a neutral stimulus becomes a CS after being paired with an establish CS (not an UCS)
First order: UCS and UCS, Second order: CS and CR
Produces a CR that is weaker and extinguishes more rapidly than the original CR
Classical Conditioning Applications
Ex. Acquiring fears
Ex. Overcoming fears/phobias
John Watson
Founder of Behaviorism
Little Albert
Watson: Little Albert
Conditioned to fear a white rat
Rat started as a neutral stimulus
Loud noise was the unconditioned stimulus
Fear of the white rat was the unconditioned response
Rat became conditioned response to the conditioned stimulus of the rat
Mary Cover Jones
Deconditioning (idea: you can’t be anxious and relaxed at the same time)
Peter: Pairing the white rat with ice cream
Therapies for Treating Fears/Phobias:
Exposure therapy
Systematic Desensitization
Exposure therapy
Extinction
Systematic Desensitization
Based on Mary Cover Jones’ deconditioning
Helping you relax in the presence of something that makes you anxious
Anxiety hierarchy
Operant Conditioning
Making an association between response and consequence(s) (Behavior is controlled by its consequences)
Important Figures of Operant Conditioning:
E.L. Thorndike
B.F. Skinner
Important Figures of Classical Conditioning:
John Watson
Mary Cover Jones
E.L. Thorndike
Law of Effect:
A response followed by a satisfying consequence (reward/positive consequence) is strengthened and more likely to be repeated
A response followed by an annoying consequence (negative) is weakened and less likely to be repeated
B.F. Skinner
Extended many of Thorndike’s ideas
Instruments: Skinner box, mazes
Distinguishes between two types of behavior: Respondent, and Operant
Skinner: Respondent Behavior
Stimulus elicits a response (stimulus, when present, will cause a response)
Focuses on the antecedents of behavior
Behavior seen in classical conditioning
What Pavlov calls an unconditioned response, Skinner calls a respondent behavior
Skinner: Operant Behavior
Stimulus emits a response
The stimulus signals you should respond (but the response is a decision that can be shaped or altered by consequence)
Focuses on the consequences of behavior
Behavior studied in operant conditioning
Basic Terminology of Operant Conditioning: Reinforcement
Increase in behavior
Basic Terminology of Operant Conditioning: Positive Reinforcement
Increase in behavior by giving something pleasant (giving)
Basic Terminology of Operant Conditioning: Negative Reinforcement
Increase in behavior by removing something unpleasant (removing)
Basic Terminology of Operant Conditioning: Reinforcers
The stimulus or event that increases the frequency of a response (stimulus given or removed)
Basic Terminology of Operant Conditioning: Primary Reinforcer(s)
Stimuli that an organism naturally finds reinforcing (things that satisfy a biological need)
Ex. Food and water
Basic Terminology of Operant Conditioning: Secondary Reinforcer(s)
Stimulus that acquires reinforcing properties through their association with a primary reinforcer (or another conditioned reinforcer)
Conditioned/learned
Learned through classical conditioning
Ex. Money and praise (value developed over time - not innate)
Basic Terminology of Operant Conditioning: Positive Reinforcer
The pleasant stimulus that is given
Basic Terminology of Operant Conditioning: Negative Reinforcer
The aversive stimulus that is removed or avoided
Basic Terminology of Operant Conditioning: Punishment
A response is weakened by an outcome that follows it (decrease in behavior)
Basic Terminology of Operant Conditioning: Positive Punishment
Decrease in behavior by giving something unpleasant
Ex. Spanking
Basic Terminology of Operant Conditioning: Negative Punishment
Decrease in behavior by removing something pleasant
Ex. Losing privileges
Basic Principles for Effective Punishment
Consistency
Immediacy
Sufficient
Instructions
Consistency
Should occur after every transgression
Immediacy
Should be swift
Sufficient
Should be enough to deter behavior
Instructions
Should tell why; verbalizations help but are not necessary
Additional Terminology of Operant Conditioning: Acquisition
Time is takes to make the association between response and consequence (Wait for behavior to occur then reinforce it)
Additional Terminology of Operant Conditioning: Extinction
The weakening and eventual disappearance of a response because it is no longer reinforced
Additional Terminology of Operant Conditioning: Spontaneous Recovery
An extinguished response returns without reinforcement (After a delay in presentation of stimulus)
Additional Terminology of Operant Conditioning: Generalization
An operant response occurs to a new antecedent stimulus (or situation that is similar to the original one - stimulus generalization)
Additional Terminology of Operant Conditioning: Discrimination
An operant response will occur to one antecedent stimulus but not to another
Additional Terminology of Operant Conditioning: Discriminative Stimulus
A signal that indicates that responding now/to the stimulus will bring you reinforcement (indicates condition for reinforcement)
Additional Terminology of Operant Conditioning: Premack’s Principle
Reinforcing a less desired behavior with an opportunity to engage in a more desire one (“Grandma’s Rule”: after eating your veggies, you get dessert)
Additional Terminology of Operant Conditioning: Escape Conditioning
Learning to end painful stimuli (painful stimulus is present)
Ex. The dog jumps over a barrier to escape from a painful electric shock
Additional Terminology of Operant Conditioning: Avoidance Conditioning
Responding to a signal to avoid a painful stimulus (painful stimulus is never received)
Ex. The dog hears a signal (discriminative stimulus) which indicates a shockwave is coming (the dog jumps away before the shock is administered)
Operant Conditioning - Acquisition: Shaping
Involves reinforcing successive approximations toward a final response
Operant Conditioning - Acquisition: Schedule of Reinforcement
(Once a behavior is shaped, it must be maintained) Timetable for determining when a behavior should get reinforced
Schedule of Reinforcement: Continuous
Reinforce every correct response (everytime the behavior is engaged in, it is reinforced)
Schedule of Reinforcement: Partial/Intermittent
Reinforce only a fraction of correct responses (only a fraction of the time is the behavior reinforced)
Schedule of Reinforcement: Partial/Intermittent: Fixed Ratio
Reinforce set # of correct responses
Schedule of Reinforcement: Partial/Intermittent: Fixed Interval
Reinforce at set time intervals
Schedule of Reinforcement: Partial/Intermittent: Variable Ratio
Reinforce unpredictable, changing # of correct responses (average responses)
