PSY 419 Learning and Conditioning Quiz 3 Study Guide (Chapters 5-7) Chapter 5 – Instrumental Conditioning: Foundations • What is instrumental behavior? What are the synonyms for “instrumental behavior” and “instrumental conditioning?” • Operant Behavior…response-stimulus behavior..bx that produces a response that alters the probability of that response occurring again in future similar circumstances • Who formulated the law of effect and how did he study it? Describe the law of effect. • Thorndike: Learning is faster and faster after multiple exposition to similar circumstances….cat and box experiment • What are the characteristics of discrete trial procedures? What are the characteristics of free operant procedures? What are the differences? • each trial ends with the removal of the organism from training environment • inst. response is only performed once per trial • maze and thorndike box's are discrete trials • operant? What is an operant? What is the defining characteristic of an • operant response: a class of responses that is defined by the effect that all members of the class have on theenvironment. • What is the definition of shaping? When should one use a shaping procedure? Describe, step by step, how you would use shaping to teach a child who only makes grunting noises to ask for candy by saying “candy.” • special application of + reinforcement • systematically reinforcing successive approximations to a desired instrumental response • What is a reinforcer (appetitive stimulus)? How do we objectively determine whether or not an event, stimulus, object, or condition is a reinforcer? • increases or maintains rate of some response... • What is an aversive stimulus? How do we objectively determine whether or not an event, stimulus, object, or condition is an aversive stimulus? • • Provide a technical definition for positive and negative reinforcement. Be able to identify and provide laboratory and real-life examples of each. How are positive and negative reinforcement different? How are they the same? • Positive: a relation where there is a positive contingency btw the instrumental response and the presentation of a reinforcing stimulus: • negative: the removal of an aversive stimulus tat increases or maintains a certain bx • Provide a technical definition for positive and negative punishment. Be able to identify and provide real-life examples of each. How are positive and negative punishment different? How are they the same? • positive pun: btw the instrumental response and the presentation of an aversive stimulus • negative: the removal of a reinforcer • What is the difference between escape and avoidance behavior? • escape: terminate or reduce • avoid: avoid aversive stimuli • What is omission training (or differential reinforcement of other behavior; DRO)? Describe how you would use omission training to decrease a student’s talking out in class. • + reinforcement can be used to eliminate undesirable. child speaking out of turn example • What is positive contrast? What is negative contrast? • effectiveness of a US is in part dependent on how suprising the appearance of a US is. + = 9.50 -> 12.50…. - is opposite • What happens to the relative efficacy of a reinforcer for a particular response as the delay between the response and the delivery of the reinforcer is increased? • efficacy of the reinforcer is reduced • What is a conditioned reinforcer? Provide a human example. • unconditioned = food water sex… conditioned= something like money • Describe Skinner’s classic superstition experiment. Provide an example of what might be considered superstitious behavior in humans and explain how past occurrences of adventitious reinforcement might have led to the superstitious behavior. • pigeons bxing when reinforcements come no matter what • Describe the experimental procedure used to demonstrate learned helplessness. What is the main outcome of the procedure? • dogs, 3 conditions. one shack, 1 shock but can escape, 1 no shock but can't escape • dogs in the shock and inescapable measure learn to take a shock when escape measures are introduces Chapter 6 – Schedules of Reinforcement and Choice Behavior • Provide the definition of a schedule of reinforcement. What is the difference between continuous and intermittent reinforcement? • Upon what basis are reinforcers delivered on ratio schedules of reinforcement? Know the definitions for fixed- (FR) and variable-ratio (VR) schedules of reinforcement. What patterns of responding are produced by each? Provide a real-life example of behavior maintained on a VR schedule of reinforcement. • What is a cumulative record? Be able to read a cumulative record and determine when responding is occurring rapidly, slowly, or not at all. • Upon what basis are reinforcers delivered on interval schedules of reinforcement? Know the definitions for fixed- (FI) and variable-interval (VI) schedules of reinforcement. What patterns of responding are produced by each? • What is a concurrent schedule of reinforcement? • What is the basic principle of the matching law? What is overmatching? What is undermatching? • matching? What is the difference between molar and molecular accounts of • What is self-control from a behavioral perspective? What is impulsivity from a behavioral perspective? • What is a small but cumulatively significant outcome? Provide a human example. • What is the basic principle of the value discounting function? Chapter 7 – Instrumental Conditioning: Motivational Mechanisms • What is the Premack principle? Using the Premack principle, be able to determine which activities will function as reinforcers for a particular organism at particular times. • What is the response deprivation hypothesis? According to this theory, how is access to a particular activity established as reinforcing? • What are the basic assumptions of behavioral regulation theory? • What is the behavioral bliss point as assumed by behavioral regulation theory? • What is the difference between associative theories of instrumental conditioning and behavioral regulation theories of instrumental conditioning?
