1. The reversal design is a continuous measure of behavior in a particular setting. The sequences of phases include the initial base (A), intervention (B), and thirdly, the return to baseline (A). The A-B-A-B has a stronger demonstration and is powerful in depicting a functional relationship between behavior and environmental manipulation. B-A-B reversal design is appropriate with dangerous behaviors and involves ethics that are geared towards withholding effective treatment. The ‘'Operation and Logic of reversal Design'' involves verification, prediction, and replication of behavior.
2. The variations of the A-B-A-B design include repeated reversals, multiple treatment reversal designs, NCR reversal techniques, DRO reversal technique, DRI and DRA reversal techniques. The repeated reversals include replications that demonstrate functional relations that are more convincing. The ‘'Multiple Treatment Reversal designs'' is used in comparing effects of experimental conditions with each or other. The NCR technique demonstrates how contingent reinforcement occurs. The DRO delivers reinforcement after a behavior that is not targeted. The DRI delivers reinforcement after a behavior that conforms to the target behavior and finally the DRA targets an alternative behavior.
Delegate your assignment to our experts and they will do the rest.
3. A sequence effect is a condition where certain variables affect a behavior influence performance in the subsequent studies. The major threat caused by sequence effect is that they can expose an individual to multiple conditions hence leading to a confounding result.
4. The behaviors that might be appropriate for the reversal design include those that demonstrate functional relationship while those that cannot apply in these criteria include the type of behavior that depicts irreversibility. Most behaviors in the reversal design have continuity or some form of repetition while the behaviors that do not fall in this category lack the continuity. Examples of behaviors in this design include the tendency of the child to cry or the act of eating junk food. On the other hand, behaviors that can fit here include failing to perform a duty such as doing homework.
5. The disadvantages of the reversible designs include its irreversible nature. Secondly, it is marked with numerous social and educational challenges. Thirdly, it is also affected by social problems. The social concerns might require the full support of everyone involved in the treatment. The educational problems can mean that the reversal phase turns out to be extremely short. Ethical concerns might, in turn, make it difficult especially when dealing with harmful situations.
6. The alternating treatment designs are appropriate in comparing two or more forms of treatments. It attempts to answer questions about whether one form of treatment is better than the other. Examples of the alternating treatment designs include alternating treatments that lack baseline, alternating treatments that follow baseline, and thirdly baseline that followed alternating treatments attached to a final treatment phase.
7. Assessing experimental control is an important step in behavior analysis. The alternating treatment design can be used to assess behavior by comparing two treatment interventions for the behavior. Supposing an individual has a behavior of getting moody while another has a behavior crying, two treatment interventions can be run on the individuals and then determine the success of each depending on the result it will have. The success of an intervention will be determined by the speed at which it takes to bring the desired effects.
8. In the alternating treatment behaviors that lack a baseline, the presentation of the treatments is random to the subjects on different days and sessions. The data in the pre-invention baseline are not collected. When the baseline is followed by alternating treatments data is first collected before treatments are presented. The data also provide additional information concerning changes beginning from pre-treatment to treatment. In the final phase, the best and the most effective treatment is established during the study.
