Behavior reduction strategies “when implemented immediately after a target behavior, reduce the future probability of the target behavior recurring.” Zirpoli & Melloy, 2001
Is there really a problem? • 5 questions should be considered before a decision is made to eliminate or modify a behavior • Is the behavior causing physical harm to the student or others? • Is the behavior disruptive to the student’s learning or the learning of others? • Does the behavior appear to be triggering additional problem behaviors or emotional reactions in the student or others? • Is the behavior causing the student to be socially excluded? • Is the behavior related to a medical condition?
Chapter 8 • Arranging consequences to decrease behavior • Strategies of differential reinforcement • Removal of desirable stimuli • Presentation of aversive stimuli
Aversives in the educational setting • Aversive is an unpleasant consequence • intervention as action by the teacher to decrease inappropriate behavior • restriction as the degree of regulation to control the use of an intervention (Tobin & Sugai, 1993) • Tobin and Sugai conducted a survey to determine attitudes of educators about various aversive interventions.
Rankings from questionnaire • mild electric shock • exposure to ammonia • wearing a negative sign • hits and slaps • tastes of hot sauce • paddling • tastes of lemon juice • cloth restraints • wearing an eye screen • exposure to water mist
Differential reinforcement • Differential reinforcement is defined as the process of reinforcing an appropriate behavior in the presence of one stimulus, and simultaneously, not reinforcing an inappropriate behavior in the presence of another stimulus.
Level 1 - Differential reinforcement • Differential reinforcement of low rates of behavior - DRL • Differential reinforcement of other behaviors - DRO • Differential reinforcement of incompatible behavior - DRI • Differential reinforcement of alternative behaviors - DRA
DRA • Definition- reinforcing a behavior that is an alternative to the targeted behavior (dissimilar but not incompatible). • How- when the student displays the inappropriate behavior the teacher redirects the student to the chosen alternative behavior. • When- every time the inappropriate behavior is displayed. • Note: sometimes DRA is used in conjunction with a mild punisher if the student continues to exhibit the inappropriate behavior.
DRL • DRL: reinforcement schedule used to decrease rate of inappropriate behavior • Full Session: must meet criteria for whole session • Interval Session: must meet criteria when session broken into smaller intervals. Intervals lengthened as behavior decreases. • How: 1. Record baseline • 2. Space criteria • 3. Decide what feedback to give students • Advantage: reduce behavior, progressive • Disadvantage: slow process, not appropriate for violent behavior.
DRO Involves reinforcement for the non-occurrence of the target behavior. • Specified period of time - full-session DRO - time period divided into smaller intervals • Permanent product data -e.g. smiley face on paper without doodlesFACTORS • “pure” DRO-reinforcement no matter what other behaviors are expressed • behavior vacuum-need to identify appropriate behavior to replace target behavior • reinforcer needs to be more motivating than the one currently maintaining the inappropriate behaviorGuidelines • initial DRO interval based on data • smaller increased to longer
DRIDifferential reinforcement of incompatible behavior • DRI increases behavior that excludes the occurrence of the target behavior. • Both behaviors cannot occur simultaneously • Example: Reinforce someone for staying awake instead of sleeping with positive comments and scheduling physical activity during the typical sleep period. • FBA should be performed in order to find the causes of the underlying behavior • The student should be able to perform the replacement behavior. • Start with a CRF schedule and fade over time.
Differential reinforcement of behavior • I need 4 groups of experts: • DRL • DRO • DRI • DRA
DR intervention steps • Select the target behavior to be changed • Select the positive behavior to the target behavior. • Select the appropriate differential strategy (DRO,DRI, DRL, DRA) • Determine the reinforcers to be used in the intervention • Determine criteria for success • Implement the intervention • Evaluate the results of the intervention
Extinction • The discontinuation or withholding of the reinforcer of a behavior that has previously been reinforced is called extinction. This process is also known as systematic ignoring. • Guidelines: when the target behavior is exhibited, remain impassive; give no indication that you are aware of the behavior. Continue whatever activity you are presently doing; if the behavior persists, turn your back and walk away.
Reprimands Another form of punishment is the reprimand. Reprimands are useful when a child is engaging in behavior that necessitates immediate action because it is potentially harmful to self, others or property. A reprimand should include a statement of an appropriate alternative to the inappropriate behavior.
Guidelines for reprimands • Be specific, tell the child exactly what inappropriate behavior is being reprimanded. • Reprimand the behavior, not the child. • Reprimand immediately. • Be firm in voice and physical demeanor. • If danger of harm, remove child. • If necessary back up the reprimand with the loss of privileges • Encourage child to behave appropriately and include a statement of the appropriate behavior in the reprimand. • Be calm. • When it is over, do not keep reminding the child of past inappropriate behavior, avoid embarrassing in the presence of others, Use nonverbal reprimands - shake your head no, point your finger, frown,etc. • Always observe the child’s reaction to the reprimand to determine if it is an aversive.
Reprimands • Do these fit guidelines? • http://www.youtube.com/watch?v=2Yb7AWs7IuY • http://www.youtube.com/watch?v=ipOnrefStYU
Loss of privileges • Loss of privileges is a negative behavior management intervention though its results may be positive. • (response cost) • When this is applied - a portion of the child’s present or future positive reinforcers are taken away following the exhibition of the target behavior.
Guidelines for loss of privileges • Be sure the child understands the relationship between the target behavior and the privilege to be lost. • Be sure the student childs the punishable behavior and the consequence of exhibiting it. Use natural or logical consequences • Apply the loss of privilege fairly • Avoid warning, nagging or threatening. • Do not debate the punishable behaviors, the rules, or the punishment once these have been established • Do not become emotionally involved. Don’t feel guilty when the child loses a privilege. If the child knows the rules and the consequences of the behavior, then they have chosen to break the rule and suffer the consequence. • Be consistent • Reinforce appropriate behaviors, do not emphasize inappropriate behaviors.
Effectiveness • Reprimand - is increased when paired with nonverbal behavior associated with a verbal command - (pointing a finger) & delivered in close proximity to the individual who is the target of the reprimand. • Loss of privilege - most effective when it is a logical or natural consequence of the inappropriate behavior - late for bus - miss it
Time-out • Time out is the removal of the child from an apparently reinforcing setting to a presumable non-reinforcing setting for a specified and limited period of time. • In other words - time out is time away from positive reinforcement.
Time out has two important factors: • contingent upon the exhibition of the target behavior • discrepancy that is meaningful to the student exists between the time in and time out environments. • Such removal can effectively decrease a target behavior. • Time out has been proven to be more effective than verbal reprimands (Jones, Sloane & Roberts, 1992)
Three types of time out • Observational time out (head down on desk, outer perimeter, removing activity materials, reduction of room illumination) • Exclusion - placing a screen between student and the rest of the class -student remains in the class. • Seclusion - time out room, the student leaves the classroom and goes to an isolated room.
Effectiveness of time out is contingent upon • Characteristics of the individual child • Teachers consistent application of the intervention • Child’s understanding of the rules of time out • Characteristics of the time out area • Duration of time out • Evaluation of the effectiveness of the intervention
Overcorrection • A punishment procedures that required the individual who misbehaves to improve the environmental effects of the misbehavior and/or repeatedly perform the appropriate form of the target behavior in the environment in which the misbehavior was exhibited.
Other terms: Overcorrection • Positive practice, functional movement training, autism reversal, and educative restitution
Overcorrection characteristics • directly related to misbehavior • directly experiences the effort normally required of others to correct the products of the misbehavior • instituted immediately • performs overcorrection act rapidly so that the consequences constitute an inhibitory effort requirements • individual is instructed and manually guided through the required acts - depending on individual
Two types of overcorrection • Positive practice - the individual who exhibits the inappropriate behavior is required to repeat over and over the appropriate target behavior • Restitution - is correcting or setting right whatever in the environment has been disturbed or disrupted by the inappropriate behavior and doing so in a manner that is more corrected than it actually was disturbed or disrupted • example: slamming a door and then opening and closing the door quietly 20 times. • No throwing toys - pick up all the toys
Satiation • Decreasing or eliminating an inappropriate behavior as a result of continued and increased reinforcement of the behavior. • Very common. • “getting too much of a good thing” • variable reinforcement schedules are more resistant to satiation than a continuous or fixed
Punishment • Intervention used to decrease or eliminate an inappropriate behavior. • Two forms • addition of an aversive stimulus as a consequence of behavior • subtraction of something the child perceives as desirable • (punishment by deprivation is generally considered less harmful than the addition of physical or psychological aversive stimuli)
Punishment • Punishment always works. If you try something that does not decrease behavior, you simply have the wrong stimulus. • For example, it is only time out if the behavior decreases. If the student would rather be alone, then it is not working. You can only tell - by looking at the data.
Timeout • The behavior needs to be specified. • Time out should only be used for one or two specified problems. • This limits the amount of time out being used, if overused, it may well lose its effectiveness. • Time out is not a procedure to be used at a whim. It has to be well thought out and part of a written plan for a student. • Everyone needs to understand the rules.
Timeout • The shorter the time spent in timeout, the better, because the targeted behavior may not be happening, but no learning is taking place either. If the student would happen top perform a desirable behavior, it would not be readily reinforced.
Time out • The location has to be safe, well-ventilated, and lighted. The student must be observed at all times. Some way to have eye contact. These qualifications eliminate the bathroom and hall closet. There is nothing more controversial than timeout.
Time out • You have a place that meets the ethical standards. You program has been written and approved. You have given a warning and Jason threw a chair. What do you do? • First, tell him in your firmest and most commanding voice (not yelling)- Jason you throw a chair, go to time out. If Jason doesn’t go, you may have to physically take him. DO NOT touch a student except as a last resort and only if you have enough help to overpower if necessary. Never let the student escape. It is better to let him avoid time out than to let him physically hurt himself or someone else, or escape.
Ethical concerns • There are more obvious ethical concerns when using deceleration procedures than when using acceleration ones. One rule of thumb says - implement deceleration at a ratio of 1:3. This means for every behavior you are trying to decrease, you should be teaching or increasing 3 others. Usually it is best to try a positive approach first, like reinforcing an incompatible. In some places documentation of this is required by law or agency guidelines.
