List and define the three different types of Differential Reinforcement procedures-
Differential Reinforcement of Alternative Behavior (DRA):
Put any undesirable competing behaviors on extinction. Reinforce desirable, tb/Alternative behaviors.
Differential Reinforcement of Low Rates of Behavior (DRL): Goal is to Decrease problem behavior, NOT Extinguish Two Methods- Full session & Spaced responding:
- Full session: tell the client before session/time frame that the bx is limited to x amount of times (raising your hand in class, games of xbox played) and give them a means to keep track of bx occurrences such as a check list. Give them a sheet which has 4 boxes and as the behavior occurs, they are to check a box.
- Spaced-Responding: Have set minimum time that is to elapse between each occurrence of bx. Monitor through stopwatch/phone.
Differential Reinforcement of Other Behavior (DRO): Reinforcer is contingent on the absence of the problem behavior. Meaning the SR is not delivered after the pb (extinction). Reinforcer is delivered after x amount of time passes w/o occurrence of pb.
- Time interval between bx should gradually increase.
- Not to be confused with reinforcement of any other bx
- Another name is Differential Reinforcement of 0 Rates of bx.
What are the Steps of implementing DRA?
- Define the Desirable bx.
- Define the Undesirable bx.
- Identify the Reinforcer.
What are the Steps/key factors of implementing DRO?
- Identify the Reinforcer for the Problem Behavior
- Identify the Reinforcer to use in the DRO procedure
- Choose the initial DRO Time Interval
- Eliminate the Reinforcer for the pb and Deliver the SR for the Absence of the pb.
- RESET the interval if the pb occurs
- Gradually increase the interval length
What are the two ways to Determine Reinforcers to use in a DRA intervention?
First - conduct an FBA to determine the SR maintaining the problem bx, your substitute SR will be based on this. 1) Verbal Preference Assessment: Ask the person or someone close what items activities are preferred. 2) Item or Activity Preference Assessment
List the three types of Preference Assessments & how each are conducted.
Singe-stimulus: Each item presented one at a time, calculate & graph % of times each item chosen. Paired-stimulus Preference Assessment: Two items presented. Calculate & graph % times each item chosen. Multiple-stimulus without replacement preference assessment: Record which item is chosen, remove chosen item, present remaining items. Graph Hierarchy
Why are reinforcer assessments conducted?
To validate preference assessment outcome. Process: - Determine operant response. - Conduct BL - Conduct SR phase where SR contingent upon each occurrence of operant response.
Describe DRA for problem behavior maintained by attention.
Provide attention on an FR1 for desirable bx - No longer deliver attention (SR) for undesirable bx.
Describe DRA for problem bx maintained by tangibles.
Provide preferred tangible immediately on FR1 for desirable bx. - No longer deliver tangible (SR) for undesirable bx.
Describe DRA for problem bx maintained by escape.
Provide escape (break) immediately FR1 style for desirable bx. - No longer deliver/allow escape for/when undesirable bx occurs.
What is the appropriate course of action as Differential Reinforcement procedure starts to become effective?
After desirable continuously occurs & undesirable decreases, thin the schedule of SR (intermittently delivered) to promote maintenance.
What is functional communication training(FCT)?
Desirable bx is a COMMUNICATIVE response to gain access to SR - “Play with me” - “Can I have __?” - Signing for desired Sr
List several examples of communicative responses (FCT) that can be used depending on the person’s abilities.
- Asking for ____ - Signing for ___ - Using picture card - Using communication device
How is the initial DRO interval determined?
Through an FBA - determine WTF SR is so that SR may be replace with preferred SR for preferred bx.
If problem bx occurs during DRO, what should the change agent do?
Restart the timer.
What is the difference between Full-Session DRL & Spaced-Responding DRL?
Full-session: SR delivered if fewer than a specified number of responses occur during a period of time = full-session
Spaced-responding: SR delivered contingent on a predetermined amount of time between responses.
Explain the DRO procedure steps. Give an example.
Identify PB. Identify SR maintaining PB bx. Come up with SR that will promote preferred bx. Perform FBA to confirm new SR’s effectiveness. Plan delivery of SR contingent on less than amount of time that passes, on average, between each PB. E.g.- Johnny keeps feeding the dog at the dinner table. Functional SR is attention- replace SR with games at the table(i spy). Because Johnny seems to feed the dog about every 5 minutes, deliver SR about every 3 minutes, gradually increasing as Johnny’s table manners improve.
Explain the DRL procedure process.
First determine if DRL is appropriate- want to decrease rate of bx but eliminate it. Determine full-session vs spaced-responding. If timing of bx, how quickly, not how often/overall rate, is important, then Spaced-responding most appropriate. Full-session Eg- Aaron keeps checking his phone for the score of the chiefs game during church. Tell Aaron he can only check 3 times. Give him a notecard with 3 empty boxes. Spaced-responding Eg- Tanya eats sweets frequently throughout the day. Limit her to just 1 sweet every 3 hours. Set a timer to go off every 3 hours.
List 3 ways antecedents can be manipulated to increase desired bx.
1) Present Sd or cues that have stimulus control over desired bx (make desired bx more likely) 2) Arrange EO such that consequences of desirable bx more reinforcing. 3) Decrease response effort for desirable bx
List 3 ways antecedents can be manipulated to decrease PB bx.
1) Remove Sd/cues for undesirable bx 2) Arrange AO to decrease the value of reinforcer for undesirable bx. 3) Increase response effort for undesirable bx.
What are the variations of DRO? Explain.
Whole-interval DRO - PB must be absent for the ‘Whole Interval’ for SR to be delivered Momentary DRO - PB must be absent at the end of the interval for SR to be delivered (don’t have to watch person entire time)
List ways in which one could decrease the aversiveness of demand contexts in an antecedent intervention for PB maintained by escape.
- Provide potent Sr for correct responding. - Include instruction within context of preferred activities. - Decrease # of demands/duration of demand period. - Use errorless learning/provide help to complete the task.
Define TO. What are the two types?
Loss of access to ALL positive reinforcers for a BRIEF period (1-3 minutes). Non-exclusionary & Exclusionary
What is Non-exclusionary TO? Give a couple examples.
Individual remains in room while being removed from access to positive SR Eg- Time-out Ribbon / “Sit & watch” / TO mat or chair
What is Exclusionary TO? Examples?
Individual is removed from the room (the reinforcing environment) where PB occurred & is taken to another room, which removes ALL sources of positive SR. - Room w/o positive SRs - Principal’s office - Adjacent classroom
Why is it important to determine the function of the PB prior to implementing TO?
To know the best format of TO to apply if TO is even applicable to the Sr maintaining the bx.
What are some essential qualities of TO?
Time-in environment MUST be Positively Reinforcing for TO to be effective. Time-out MUST be free of positive reinforcers TO is NOT appropriate if PB maintained by social negative SRs (escape) TO is NOT appropriate if PB is maintained by automatic positive SR (sensory stimulation) because time alone would provide continuous opportunity to engage i PB bx.
What functions should TO be used for?
Social positive
What functions should TO NOT be used for?
If PB is Socially Negatively reinforced. If PB is reinforced by Automatic Positive stimuli
If a TO room is used, what safety procedures need to be followed?
Room must be safe: - No sharp objects, objects that could be harmful - Well lit - Observation window - No inside lock
Explain the necessary factors that need to be a part of Time-in for it to be effective.
Environment needs to be Socially, Positively reinforcing. Cannot acknowledge person after implementation
What is Response Cost?
Negative Punishment - Removal of a specific AMOUNT of a specific Sr that person already has, contingent on occurrence of PB.
What are the similarities & difference between RC, TO, & EXT?
Similarities - used to decrease problem bx. Differences - - EXT: pb no longer results in SR that previously maintained bx - TO: Person removed from access to ALL reinforcement - RC: Specific amount of one, specific Sr person ALREADY has is removed
Give an example of Immediate Response Cost & Delayed Response Cost.
Immediate - ‘token’ loss or loss of ongoing Sr. Delayed - fines payed later; loss of opportunity to engage in activity; loss of allowance.
What ethical considerations must be accounted for when implementing RC?
Cannot take away personal possessions Depriving someone of meal/food/water
Explain Overcorrection-
What is it?
What different forms of Overcorrection are there?
A procedure with the goal or decreasing ‘aggressive and disruptive behaviors’
- Positive Practice
- Restitution
What is Positive Practice?
Examples-
A type of overcorrection-
Client has to engage in correct form of relevant bx contingent on pb.
- If child yells at another demanding something, child must ask nicely 15x.
- Individual wets his bed, get out of bed & go to bathroom 5x.
- If individual runs around pool, walk around pool 3x
What is Restitution?
Examples-
Contingent on pb, client must correct pb and Restore the environment to a condition better than what existed before pb.
Knock chair over- pickup chair & straighten all chairs
Explain Contingent Exercise-
Form of Positive Punishment.
- Client must engage in some form of physical exercise contingent on an instance of pb.
Explain Guided Compliance-
Form of Positive Punishment.
Contingent on occurrence of pb, client is physically guided through correct form of behavior.
What is Physical Restraint?
Variation?
Positive Punishment Procedure
- Change agent holds immobile the part of the client’s body that is involved in the pb
Variation is Response Blocking-
- Change agent prevents the occurrence of a problem behavior by physically blocking the response.
E.g.- Eating before praying = block mouth.
Key factors & ethics of POS PUN-
Only used as Last Resort. Mostly for most severe & difficult to treat pb.
- Negative Punishment used more often, deemed more acceptable by society.
- Conduct FBA first
- Ensure aversive stimulus acts as Punisher
- ## Person must be fully informed & have given consent
Define Generalization-
Changes in bx occur in all relevant situations or contexts in a person’s life (outside the training context)
What are some ways to Promote Generalization?
- Reinforce occurrences of generalization
- Train skills that contact natural contingencies of SR
- Modify contingencies of SR and PUN in natural environment
- Incorporate variety of relevant stimulus situations in training
- Incorporate common stimuli
- Teach range of functionally equivalent responses
- Provide cues in natural environment
- Incorporate self-generated mediators of generalization
Provide two examples of how you could provide cues in the natural environment to promote generalization.
Hand washing sign above sink. Click-it or ticket signs.
Describe how you could use self-generalized mediators of generalization to promote generalization of learned behaviors.
Memorize & repeat to yourself what it is that you learned. Make index cards reminding you to engage in x behavior & include empty boxes to check of at each occurrence of desired bx.
Identify & describe the four guidelines for achieving a generalized reduction in a PB.
- Perform Functional Assessment to discover SR maintaining bx. - Plan for generalization in advance. - Focus on Functionally Equivalent Alternative bx to replace the problem bx. - Maintain extinction contingencies across situations & across time.
Define Self-management:
Process in which person uses behavioral principles/procedures to change their OWN behavior
