Reversal Design Variations
Multi-Element Design
Multi-Element Variations
100
The Reversal Design requires 3 phases within the design. They are...
1. initial baseline
2. intervention
3. return to baseline
100
Repeated Reversal Design is when
when the independent variable is withdrawn and reintroduced once again (A-B-A-B-A-B).
100
The purpose of the multi-element design is
used to compare the effects of 2 or more treatments.
100
Which variation is the primarily used for FA's
Single Phase Multi-Element
200
In an ABAB design the second intervention phase represents what...
the replication of effect has been achieved and functional relation is demonstrated
200
This variation is when the intervention occurs prior to the baseline condition
B-A-B-(A) Design
200
Alternating treatment designs works by
having a rapid alternation of 2 or more distinct treatments (independent variables) while their effects on the target behavior (dependent variable) are measured.
200
What is a Two-Phase Multi-Element Design
300
What is irreversibility
the level of behavior observes in an earlier phases cannot be reproduced even though the experimental conditions are the same as the earlier phase
300
This design is used to compare the effects of two or more experimental conditions to baseline and/or to one another
Multiple Treatment Reversal Design
300
1 advantage is:
Treatment withdrawal not required
Allows rapid comparison
Minimizes irreversibility problem
Minimizes sequence effects
Accommodates unstable data
Reveals generalization of effects
Intervention can begin immediately
300
This is an example of:
Three Phase Multi-Element Design
400
True or False: A-B-A design ends with the treatment condition in place
False - ABAB
400
NCR Reversal Design is when
the behavior change is the result of contingent reinforcement, not simply the presentation of or contact with the stimulus event
400
True or False: When the data paths for two treatments show an overlap with each other and either stable levels or opposing trends, a clear demonstration of experimental control has been made.
False - you want NO overlap
400
This Design is when participants choose between two or more concurrently available treatments
Concurrent Chain (Or Scheduled Chain) Design
500
What is the main ethical concern with implementing Withdrawal Designs?
Serious ethical concern when reversal design used for SIB or aggressive behaviors.
It may be determined that withdrawing an intervention that shows improvement to a person’s health or safety would be unethical.
500
This design is when the control condition consists of delivering reinforcement immediately following the subject's performance of any behavior other than the target behavior.
DRO Reversal Design
500
True or False: A distinct stimulus (like a sign, verbal instruction, different colored worksheets associated with each treatment) can aid in the subject’s discriminating the treatment condition.
True
500
In a single phase design, this type of condition provides valuable information on any differences in responding under the intervention treatment(s) and not treatment
No Treatment Condition (alone condition in FA)
