Reinforcement, Punishment, Avoidance Learning, and Escape Learning HOW TO APPLY THESE IN AN EDUCATIONAL ENVIRONMENT Common Problems of the Classroom Student attendance is down. Students don’t participate in class - they don’t raise their hands when asked a question. Student constantly talks out of turn. Students won’t quiet down once class starts. Students have a tendency to continue to talk to each other once class starts. Common Problems of the Classroom What other problems can you come up with? List Goals for Today Learn how to define, recognize, and apply terms to classroom situations: Positive Reinforcement Negative Reinforcement Punishment Avoidance Learning Escape Learning Try and Define Positive – Negative – Reinforce – Punish – Positive Reinforcement The word positive in positive reinforcement DOES NOT refer to the pleasantness of the stimulus. It means a stimulus is added or applied to the situation. Any stimulus that works to increase the frequency of a behavior it follows is a positive reinforcer, even if it does not seem like it should be rewarding. http://www.intropsych.com/ch05_conditioning/positive_reinforcement.html Positive Reinforcement Simplified: Behavior = Increase (Arrow Up) (plus sign) something to Increase (Arrow Up) Behavior What you are adding (not equal sign) Pleasant As long as it increases behavior Positive Reinforcement Additional examples will go here Students can also supply Negative Reinforcement Occurs when a behavior is reinforced by removal of a stimulus. The word negative DOES NOT mean unpleasant It means a stimulus is removed or subtracted from the situation as a form of reinforcement. http://www.intropsych.com/ch05_conditioning/negative_reinforcement.html Negative Reinforcement Simplified: Behavior = Decrease (Arrow Down) (- sign) something to Increase (Arrow Down) Behavior What you are adding (not equal sign) Unpleasant As long as it decreases behavior Negative Reinforcement Additional examples will go here Students can also supply Positive vs. Negative Reinforcement Reinforcement is used to INCREASE a behavior Positive Reinforcement Negative Reinforcement +++++++++++++++++++ -- - - - - - - - - - - - - - - - - - - - - - - - - - - Adding Something Removing Something candy, stickers, treat, certificate, lunch, extra credit no homework, exemption from test Insert example that is not necessarily positive but increases behavior Insert example that is not necessarily positive but increases behavior Punishment Punishment occurs when a stimulus is applied and has the effect of making a behavior less frequent. Sometimes this is called positive punishment. Positive in this context means a stimulus is added. http://www.intropsych.com/ch05_conditioning/punishment.html Punishment Simplified: Behavior = Decrease (Arrow Down) (+ or -) something to Decrease (Arrow Down) Behavior What you are adding (not equal sign) Pleasant As long as it decreases behavior Reinforcement vs. Punishment Reinforcement Punishment INCREASES Behavior DECREASES Behavior Examples similar to compare and contrast Examples similar to compare and contrast Back to the Classroom Problem: Student attendance is down. A professor has a policy of exempting students from the final exam if they maintain perfect attendance during the quarter. His students’ attendance increases dramatically. What/Why:The exemption from the final exam is an example of negative reinforcement because something is taken away that increases the behavior (attendance). Back to the Classroom Problem: Student attendance is down. A professor has gives extra credit if they maintain perfect attendance during the quarter. His students’ attendance increases dramatically. What/Why:The extra credit is an example of positive reinforcement because something is added to increase the behavior (attendance). Back to the Classroom Problem: Student attendance is down. A professor has gives additional assignments to those who miss his classes. His students’ attendance increases dramatically. What/Why:The additional assignments are examples of punishment because something is added to decrease the behavior (missing class). Back to the Classroom Problem: Student attendance is down. A professor has gives takes participation points off to those who miss his classes. His students’ attendance increases dramatically. What/Why:The removal of participation points is an example of punishment because something is removed to decrease the behavior (missing class). Try and Define Escape – Avoid – Escape Learning Occurs when the animal learns to perform an operant to terminate an ongoing, aversive stimulus. It is a "get me out of here" or "shut this off" reaction, aimed at escape from pain or annoyance. The behavior that produces escape is negatively reinforced (reinforced by the elimination of the unpleasant stimulus) http://www.intropsych.com/ch05_conditioning/avoidance_and_escape_learning.html Escape Learning Additional examples will go here Students can also supply Avoidance Learning Escape conditioning is converted into avoidance conditioning by giving a signal before the aversive stimulus starts. If the animal receives a cue or signal that an aversive stimulus is coming, then after one or two occurrences of the punishing stimulus the cue will trigger an avoidance behavior. This kind of learning occurs quickly and is very durable. http://www.intropsych.com/ch05_conditioning/avoidance_and_escape_learning.html Avoidance Learning Additional examples will go here Students can also supply Reaching Avoidance Learning Punishment or Reinforcement? >>>>> Escape Learning >>>>>>>>>>Avoidance Learning
