Overview • Operant conditioning • Educational applications of operant conditioning principles • Social learning theory • Using computer-assisted instruction in your classroom Copyright © Houghton Mifflin Company 7–2 Operant conditioning • Theorist – B. F. Skinner • Basic assumption – Voluntary responses are strengthened or weakened as a result of their consequences • Original research – Rats in Skinner boxes Copyright © Houghton Mifflin Company 7–3 Operant conditioning concepts • Positive reinforcement – Strengthening (increasing) a behavior by presenting a positive stimulus immediately after the behavior has occurred • Negative reinforcement – Strengthening (increasing) a behavior by removing a negative stimulus immediately after the behavior has occurred Copyright © Houghton Mifflin Company 7–4 Operant conditioning concepts • Presentation punishment (Type I) – Weakening (decreasing) a behavior by presenting an aversive stimulus immediately after the behavior has occurred • Removal punishment (Type II, time-out) – Weakening (decreasing) a behavior by removing a positive stimulus immediately after the behavior has occurred Copyright © Houghton Mifflin Company 7–5 Operant conditioning concepts • Extinction – When a previously reinforced behavior decreases in frequency and eventually ceases altogether because reinforcement is withheld • Spontaneous recovery – When an extinguished behavior reappears without having been reinforced Copyright © Houghton Mifflin Company 7–6 Conditions that define reinforcement, punishment, and extinction Type of + Stimulus Desirable Action + = Result Present Effect on Behavior Strengthen Aversive Remove Strengthen Negative reinforcement Aversive Present Weaken Desirable Remove Weaken Desirable Withhold Weaken Type I (presentation) punishment Type II (removal) punishment Extinction Copyright © Houghton Mifflin Company Positive reinforcement 7–7 Operant conditioning concepts • Generalization – When an individual learns to make a particular response to a particular stimulus and then makes the same or a similar response in a slightly different situation • Discrimination – When an individual learns to notice the unique aspects of seemingly similar situations and thus different ways of responding Copyright © Houghton Mifflin Company 7–8 Operant conditioning concepts • Shaping – Reducing complex behaviors into several more simple behaviors – Reinforcing successive approximations to the complex behavior Copyright © Houghton Mifflin Company 7–9 Schedules of reinforcement • Fixed interval schedule – Reinforcement occurs after a specific amount of time • Variable interval schedule – Reinforcement occurs after a random amount of time Copyright © Houghton Mifflin Company 7–10 Schedules of reinforcement • Fixed ratio schedule – Reinforcement occurs after a specific number of responses • Variable ratio schedule – Reinforcement occurs after a random number of responses Copyright © Houghton Mifflin Company 7–11 Educational applications of operant conditioning principles • Programmed instruction • Computer-assisted instruction (CAI) – Drill-and-practice programs – Simulation programs – Tutorial programs • Integrated learning systems (ILS) Copyright © Houghton Mifflin Company 7–12 Educational applications of operant conditioning principles • Behavior modification – Shaping – Token economies – Contingency contracts – Extinction, time-out, and response cost – Punishment Copyright © Houghton Mifflin Company 7–13 Steps in shaping • • • • Select the target behavior Obtain realistic baseline data Select potential reinforcers Reinforce successive approximations for the target behavior each time they occur • Reinforce the newly established target behavior each time it occurs • Reinforce the target behavior on a variable reinforcement schedule Copyright © Houghton Mifflin Company 7–14 Social learning theory • Theorist – Albert Bandura • Basic assumption – Observation and imitation of a model lead to changes in behavior • Original research – Imitation of aggression by young children Copyright © Houghton Mifflin Company 7–15 Types of observational learning effects • Inhibition – Learn not to do something we already know how to do because a model has refrained from behaving in that way, has been punished for behaving that way, or does something different than we intended • Disinhibition – Learn to exhibit something not approved of because a model has done the same thing without being punished Copyright © Houghton Mifflin Company 7–16 Types of observational learning effects • Facilitation – Prompted to do something that we do not ordinarily do because of insufficient motivation because a model has done the same thing • True observational learning – Learn a new behavior pattern by watching and imitating the performance of someone else Copyright © Houghton Mifflin Company 7–17 Processes in observational learning • Attention – Paying attention to a model’s behavior • Retention – Encoding behavior into memory • Production – Performance of behavior • Motivation – Reinforcement of behavior Copyright © Houghton Mifflin Company 7–18 Motivation and reinforcement • Direct reinforcement – Individual watches a model perform, imitates the behavior, and is reinforced by the model • Vicarious reinforcement – Observer anticipates receiving a reward for behaving in a given way because someone else has been so rewarded Copyright © Houghton Mifflin Company 7–19 Motivation and reinforcement (cont’d) • Self-reinforcement – Individual strives to meet personal standards and does not depend on or care about the reactions of others Copyright © Houghton Mifflin Company 7–20 Factors that affect self-efficacy • • • • Self-assessment of past performance Verbal persuasion from someone else Emotional reaction to task Vicarious experience of others Copyright © Houghton Mifflin Company 7–21 Behaviors affected by self-efficacy • The goals and activities in which a person chooses to engage • The kind of thought processes a person uses • How hard and long a person strives to achieve a goal • The kinds of emotional reactions a person experiences during tasks Copyright © Houghton Mifflin Company 7–22 Research on social learning theory • Effects of modeling on aggression • Effects of modeling on the learning of cognitive skills • Effects of modeling on self-efficacy Copyright © Houghton Mifflin Company 7–23 Major types of CAI programs (Grabe & Grabe, 2001; Neill & Neill, 1993) Type of Program Drill and Practice Tutorial Problems-Solving Programs: Simulations and Games Copyright © Houghton Mifflin Company Purpose Practice knowledge and skills learned earlier to produce fast and accurate responses Teach new information (e.g., facts, definitions, concepts) and skills Teach new information and skills and provide an opportunity to apply what was learned in a meaningful context that would otherwise be unavailable because of cost, physical danger, and time constraints
