REINFORCEMENT AND FEEDBACK Damon Burton University of Idaho
ABC’S OF BEHAVIOR CONTROL • If antecedentstimuli (A) are present, • AND behavior (B) is emitted, • THEN consequence (C) will occur.
ANTECEDENTS: STIMULUS CONTROL • Discriminative Stimuli – are antecedents that signal likely consequences of particular behaviors in specific situations. • For example, the ability to read and react in sport uses this principle. • Stimulus control – occurs when antecedents are influential in prompting a specific behavior.
RESPONSE CONSEQUENCES • Consequences always involve either the presentation, nonoccurrence or removal of a positive or aversive stimulus. • Teachers and coaches can choose to use either positive control, aversive control or a combination of the 2 to motivate students or athletes.
REINFORCEMENT TERMINOLOGY • What is reinforcement? • What is punishment? • What is extinction? • What is the difference between positive and negative reinforcement? • What is the difference between the 2 types of punishment?
5 BASIC RESPONSE CONSEQUENCES Present Remove Extinction (weakens behavior) Response Cost Punishment (weakens behavior) Positive Stimuli Positive Reinforcement (strengthens behavior) Negative Reinforcement (strengthens behavior) Aversive Stimuli Punishment (suppresses/weakens behavior)
WHAT IS REINFORCEMENT? • Reinforcement – is anything that increases likelihood that a behavior will occur in the future under the same conditions. It may enhance both the quantity and/or quality of a behavior. • For example, telling an athlete “good job” when she masters a new skill. • For example, increasing an athlete’s playing time for their hard work in practice. • What is the most frequently used reinforcer in sport? • What is sport’s most powerful reinforcer?
TYPES OF SPORT REINFORCEMENT • What is the most frequently used reinforcer in sport? • Verbal praise. • What is the most powerful reinforcer in sport? • Playing time.
WHAT IS PUNISHMENT? • Punishment – is the presentation of an aversive stimuli in order to decrease the quantity and/or quality of a behavior. • For example, criticizing an athlete who is not paying attention. • For example, suspending an athlete from the team for 4 games for breaking team rules. • What is the most frequently used punishment in sport? • What is sport’s most powerful punishment?
TYPES OF SPORT PUNISHMENT • What is the most frequently used punishment in sport? • Stern rebuke. • What is the most powerful punishment in sport? • Lack of playing time, suspension or dismissal from team.
EXTINCTION • Extinction – removal of a positive stimulus that has in the past followed certain behavioral results. • For example, when an athlete no longer get attention for being the “team clown,” his showoff behavior will normally decrease.
What is the difference between positive and negative reinforcement?
POSITIVE VERSUS NEGATIVE REINFORCEMENT • Positive reinforcement – present or add positive stimuli in order to increase the likelihood that the behavior, (i.e., quantity, quality or both) will occur under the same conditions. • What would be a good example of positive reinforcement? • Negative reinforcement – remove or take awayan aversive stimuli in order to strengthen a behavior that results in successful avoidance. It could change both the quantity and quality of a behavior. • Give a good example of negative reinforcement.
What is the difference between regular punishment and response cost punishment?
TWO FORMS OF PUNISHMENT • Punishment entails presentation of aversive stimuli with the effect of suppressing the behavior. • For example, making athletes run at 6:00 AM for breaking training rules. • Response Cost Punishment – contingently taking away something valued by the athlete. • For example, cutting athletes playing time for not training hard.
NEGATIVE SIDE EFFECTS OF PUNISHMENT • Punishment promotes fear and can prompt athletes to become motivated by “fear of failure.” • Develops an unpleasant team climate that reduces enjoyment. • Reduces coach’s ability to be a good “role model”. • Inhibits ability to develop good coach-athlete relationships.
WHY AVERSIVE CONTROL COACHES SUCCEED • They communicate caring for players as people so “abuse is not taken personally.” • They recruit talented athletes. • They recruit “thick-skinned” athletes who are less bothered by abuse. • They are skilled teachers and tacticians who can overcome the abuse.
POSITIVE CONTROL COACHES • Like John Wooden, they view mistakes as the “stepping stones to achievement.” • Emphasis is on improving skills rather than “not screwing up.” • Most top coaches and teachers use a very high percentage of positive reinforcement (i.e., 80-90%) and a minimal amount of punishment.
POSITIVE CONTROL COACHES • Foster a positive learning environment in which mistakes are viewed as a valuable part of learning. • Promote positive coach-athlete relationships. • Athletes like coaches more. • Athletes enjoy sport experience more. • Creates high team cohesion. • Athletes perform better.
HOW REINFORCEMENT ENHANCES BEHAVIOR • Find a reinforcer that works for each athlete. • Make reinforcement dependent on performing the desired behavior. • Make sure the athlete specifically understands why the reinforcement is being given.
WHAT IS “SHAPING?” • “Shaping” – is the process of using reinforcement to gradually enhance performance using operant conditioning principles. • Operant conditioning – the process of allowing an animal to operate on its environment until it performs correctly and then reinforce them for it to motivate them to repeat the desired behavior.
“SHAPING” -- HUMAN OPERANT CONDITIONING • Shaping – breaks down a complex skill into a series of manageable parts or goals and systematically uses reinforcement to gradually improve performance. • Each time the first goal is attained, the individual is reward. • Immediate reinforcement. • Reinforced every time.
“SHAPING” -- HUMAN OPERANT CONDITIONING • Shaping is “catching athletes doing something well or at least better.” • Gradually reinforcement is modified to enhance retention. • Delayed reinforcement. • Reinforce every 3, 5, 7, & 9 times. • Once Goal 1 is mastered, then shaping moves on to Step 2 and the process repeats.
REINFORCEMENT SCHEDULES • Continuous schedules – reinforce immediately and every time and they enhance immediate motivation. • Intermittent schedules –reinforcement is delayed and occurs on a schedule such as every 3rd, 5th, 7th, or 9th time in order to enhance long-term motivation and retention.
WHAT TO REINFORCE • Effort. • Learning new material. • Skill improvement. • Mental preparation. • Strategy selection and use. • Reaching goals.
SHAPING PROCESS B 4 3 Shaping – start with Step 1 and work on it until behavior is consistent and then move to Step 2, then Step 3 and finally Step 4. 2 1 A
FOOTBALL SHAPING EXAMPLE • Komaki & Barnett (1977) identified 3 offensive plays that were each broken down into 5 stages judged crucial for overall play execution. • For one play, the 5 stages included: • Quarterback-center exchange. • Quarterback spin and pitch. • Halfback and fullback lead blocks. • Other halfback running correct route. • Quarterback block.
BEHAVIORAL COACHING PROCEDURES • Execute the play and “freeze” on the whistle. • Coach judges correct execution and says “freeze” if incorrect. • Coach describes the incorrect behavior. • Coach models the correct behavior. • Athletes imitate correct behavior and feel good position.
FOOTBALL SHAPING EXAMPLE • The coach knew what to specifically look for and specific feedback was given on the execution of each stage. • During Stage 1, correct execution was monitored before shaping was initiated. • During Stage 2, shaping procedures were used to try to enhance execution.
FOOTBALL SHAPING EXAMPLE • Each time the play was run, the coach checked off which stages of the play were executed successfully. • Reinforcement was given to players for the stages run successfully. • Performance increased significantly for each of the 3 plays following shaping.
FOOTBALL SHAPING EXAMPLE • Play A went from 62% to 82% correct execution. • Play B improved from 54% to 82%. • Play C execution increased from 66% to 80%. • Systematic reinforcement can be a great performance enhancement strategy.
REINFORCEMENT AND INTRINSIC MOTIVATION • Self-Determination Theory – confirms that reinforcement doesn’t have to reduce intrinsic motivation as long as it is given to: • Recognize increased competence. • Greater levels of self-determination. • Contingent rewards promote IM.
MOTIVATIONAL CLIMATE • Shaping creates a mastery-oriented motivational climate than fosters IM, learning and improvement. • Outcome-based rewards promote an ego-oriented motivation climate that prompts overemphasis on winning, fear of failure, underdevelopment and underachievement.
PERFORMANCE FEEDBACK • 75% of John Wooden’s feedback to his team was instructional in nature. • Feedback motivates directly. • Feedback can also: • Focus attention. • Enhance effort. • Promote persistence. • Stimulate use of new task strategies.
BEHAVIORAL COACHING • Teach skills in a way that allows for greater opportunities to use reinforcement. • Emphasis is on systematically making closer and closer approximations of correct technique and form. • Understand correct form and focus on what it feels like.
COACHING EDUCATION • Ron Smith, Frank Smoll and their colleagues developed Coach Education Training (CET) based on observation research of effective coaches using the Coaching Behavior Assessment System (CBAS). • CET is primarily based on teaching coaches to use effective reinforcement, feedback and instructional strategies.
COACHING EDUCATION STUDIES • Trained coaches could learn to provide better instruction, reinforcement and feedback than non-trained coaches. • Athletes playing for trained coaches were more confident, less anxious, more satisfied, enjoyed sport more, and dropped out less than players who played for non-trained coaches. • Low self-esteem kids benefited most playing for trained coaches.
