CS US Conditioned response? Environment Change in internal environment to account for drug Disrupted equilibrium Drug Drug tolerance Take more drug Drug + Environment New environment??

Learning & Behavior Analysis • Simple Learning (aka Non-associative learning) • Classical Conditioning • (aka Pavlovian conditioning) • Operant Conditioning
3. Operant Conditioning B.F. Skinner Ivan Pavlov
3. Operant Conditioning • Thorndike’s Law of Effect • responses followed by satisfying consequences becomemore probable • responses followed by dissatisfying consequences becomeless probable
3. Operant Conditioning Operant Any behavior that has an observable impact on (operates on) the environment
3. Operant Conditioning Operant chamber Also know as a Skinner Box
3. Operant Conditioning Reinforcement and Punishment A stimulus that increases the probability that a behavior will recur A stimulus that decreases the probability that a behavior will recur NOT shock
Increase the likelihood that a behavior will be repeated 3. Operant Conditioning Positive and Negative Reinforcement “Good Doggy!”
Increase the likelihood that a behavior will be repeated 3. Operant Conditioning Positive and Negative Reinforcement Take the clothes pin off his tail
Decrease the likelihood that a behavior will be repeated 3. Operant Conditioning Positive and Negative Punishment “Bad doggy!”
Decrease the likelihood that a behavior will be repeated 3. Operant Conditioning Positive and Negative Punishment
Sent to your room without dessert for your bad attitude • (negative punishment) • $50 for helping the elderly woman cross the street • (positive reinforcement) • Standing on one foot to avoid being shocked • (negative reinforcement--escape) • Punched in the nose for insulting someone • (positive punishment) • Ignored for teasing • (negative punishment) • No internet for missing curfew • (negative punishment) • A week off for getting an A on your Intro Psych Exam! • (negative reinforcement??)
3. Operant Conditioning Extinction
3. Operant Conditioning Partial Reinforcement Rat 1: Gets reinforced every time Rat 2: Gets reinforced half the time
3. Operant Conditioning Partial Reinforcement Rat 1: Gets reinforced every time Rat 2: Gets reinforced half the time Which rat is more likely to stop running down the alley?
