The two-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase. Lastly the three-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase and a final best treatment phase. Applied Behavior Analysis
Applied behavior analysis
Applied behavior analysis is a scientific discipline concerned with applying techniques based upon the principles of learning to change behavior of social significance. Where the same definition is given, and it credits both the source "Baer, Wolf & Risley, 1968" and another source, called "Sulzer-Azaroff & Mayer, 1991". Beth Sulzer-Azaroff is a psychologist at University of Massachusetts Amherst, Department o…

What are the different types of alternating treatments design?
The alternating treatments design has several variations. This includes the single-phase which can be either with or without a no treatment control condition. The two-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase.
What is the difference between two phase and three phase alternating treatments?
The two-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase. Lastly the three-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase and a final best treatment phase. Applied Behavior Analysis (2nd Edition)
Can alternating treatment phases be counterbalanced or randomized?
The alternating treatment phases can be counterbalanced or randomized. In each of these designs the researcher must attend to various features of the data, including mean changes among phases, trend, variability, and autocorrelation in the data.
What is the alternating treatment design in abab?
In the alternating treatment design, following a baseline phase, the treatments are alternated in rapid succession (compared to the ABAB design which has more within phase observations or measurements) allowing a comparison of the treatment to baseline or an alternative treatment over repeated observations (e.g., ABABABABAB and ABCBCBCBC).
What is a alternating treatments design?
The alternating treatment design (ATD) consists of rapid and random or semirandom alteration of two or more conditions such that each has an approximately equal probability of being present during each measurement opportunity.
What is a three phase ATD?
ATD w/ initial baseline & final best treatment phase. Consists of 3 sequential phases: initial baseline phase, scone phase comparing alternating treatments, final phase where only the most effective treatment is administered.
What type of assessment can the alternating treatment design be used for?
It can be used to assess generalization effects. It does not include a return to baseline. It often doesn't include a baseline to begin with.
What are 2 limitations of the alternating treatments design?
limitation of alternating treatment designs: o it is susceptible to multiple treatment interference, o rapid back-and-forth switching of treatments does not reflect the typical manner in which interventions are applied and may be viewed as artificial and undesirable.
What is an ABAB study?
An ABAB research design, also called a withdrawal or reversal design, is used to determine if an intervention is effective in changing the behavior of a participant. The design has four phases denoted by A1, B1, A2, and B2. In each phase, repeated measurements of the participant's behavior are obtained.
Why is ABAB design typically superior to AB design?
Why is an ABAB design superior to an ABA design? The ABAB design is superior to the ABA design because a single reversal is not strong enough for the effectiveness of the treatment. Also the sequence ends with the treatment rather than with people withdrawing from the treatment.
Which of the following describes the phases of a reversal design?
The sequence of phases in reversal design is typically baseline (absence of independent variable), treatment (presence of independent variable, and return to baseline.
What is a multielement design in ABA?
A multielement design is also known as an alternating treatments design, because it measures the effect of multiple treatments delivered one after the other. For instance, two treatments may be compared in order to see which is most efficient in producing the target behavior.
What is a reason that alternating treatments designs may have good internal validity?
The patterns of response vary with the alternating treatment conditions, so there is minimal overlap among data in the conditions and if one treatment is consistently associated with an improved level of responding, then the design demonstrates good experimental control.
How many reversals are there in an ABAB design?
1 Reversal1 Reversal or ABAB design.
How is experimental control demonstrated in ABAB design?
Experimental control is demonstrated by the repeated changes in the dependent variable with each successive introduction of the independent variable. It protects against the inability of AB - type designs to demonstrate unequivocal control by the independent variable by showing the effects at different times.
