What is an alternating treatment design?
Identify the definition of an alternating-treatments design. An experimental design in which the replications involve presenting the different values of the IV in an alternating sequence under the same general conditions or in the same experimental phase.
What is rapid alternation design?
An experimental design in which two or more conditions are presented in rapidly alternating succession independent of the level of responding. Begins with the application of the treatment condition. Once steady state is achieved the condition is removed.
What are the elements of baseline logic in alternating treatments design?
Elements of Baseline Logic in Alternating Treatments Design Each successive data point for a specific treatment is a basis for Prediction of future responses under that condition, Verification of the prediction from the previous data point, an opportunity for Replication Experimental Control shown in Alternating Treatments Design
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 are alternating treatment designs?
a type of study in which the experimental condition or treatment assigned to the participant changes from session to session or within sessions.
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 is not an advantage of alternating treatments design?
An alternating treatments design should not be used with unstable data. This treatment design is widely used due to its ability to expose variables for being strong and reliable.
What is adaptive alternating treatment design?
The adapted alternating treatments design is a commonly used experimental design in skill acquisition research. This design allows for the evaluation of two or more independent variables on responding to unique target sets. Equating target sets is necessary to ensure a valid comparison of the independent variables.
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.
What is a single subject alternating treatment design?
Alternating treatments design: one strategy for comparing the effects of two treatments in a single subject.
What is another name for simultaneous treatment design?
A simultaneous treatment design has also been called a concurrent schedule design. It involves the concurrent or simultaneous application of two or more treatments in a single case. This contrasts to the alternation of two or more treatments in the alternating treatments design.
What is a limitation of the alternating treatments design quizlet?
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.
How many reversals are there in an ABAB design?
1 Reversal1 Reversal or ABAB design.
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.
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.
What is meant by multi treatment interference in alternating treatment designs?
In experimental designs requiring the administration of more than one treatment to the same subject(s), the effect of one treatment may be influenced by the effect of another treatment (Campbell & Stanley, 1963), a phenomenon known as multiple treatment interference.
How to implement alternating treatment?
To implement an alternating treatments design, begin as usual with a brief baseline, simply to ensure that the client actually needs intervention to eat those foods. You then alternate meals back and forth between the two different treatments that you want to evaluate.
How many alterations are required for ATD?
ATD requires a minimum of two alterations per data series.
What is an ATD?
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. As an example, it was observed during a clinical training case that a student therapist, during many sessions, would alternate between two conditions: leaning away from the client and becoming cold and predictable when he was uncomfortable, and leaning towards the client and becoming warm and open when feeling comfortable. The client would disclose less when the therapist leaned away, and more when he leaned forward. If it were assumed that the therapist had preplanned the within-session alternations, an ATD as shown in Figure 6 would be obtained. The condition present in the example at any given time of measurement is rapidly alternating. No phase exists; however, if the data in each respective treatment condition are examined separately, the relative level and trend of each condition can be compared between the two data series (hence the name between-series designs).
What is Snyder and Shaw's methodology?
Snyder & Shaw (this volume) provide a substantive discussion of the use of single-case experimental designs (also referred to as “small-n designs”) to answer an assortment of questions about sexuality. Nonetheless, we believe that the use of single-case experimental methodology to answer questions regarding childhood sexuality is of sufficient importance to warrant some discussion here.
What is single case design?
Although usually labeled a quasi-experimental time-series design, single-case research designs are described in this article as a separate form of research design (formerly termed single-subject or N = 1 research) that have a long and influential history in psychology and education (e.g., Kratochwill, 1978; Levin et al., 2003) and can serve as an alternative to using large, aggregate group designs ( Shadish and Rindskopf, 2007 ). Single-case research designs bear similarly to time-series design and have often been regarded as quasi-experimental because they usually do not (but could) include randomization in the experiment. In the single-case design, replication is scheduled to help rule out various threats to validity. Single-case designs can involve a single participant or group as the unit but differ from repeated measures and hierarchical linear modeling (HLM) designs because multiple observations are taken over a long period of time within a design structure of replication and/or randomization of the conditions of the experiment.
What is simultaneous treatment?
The same is true for simultaneous-treatment designs; a design that is appropriate for situations where one wishes to evaluate the concurrent or simultaneous application of two or more treatments in a single case. Rapid or random alteration of treatment is not required with simultaneous-treatment design.
When to use ATDs?
ATDs are ideally used with behaviors emitted at a relatively high frequency that correspondingly allows many instances of each alternate intervention to be applied. However, the design may be used with relatively infrequent behaviors if data is collected for a longer period of time.
