What does the letter B represent in an AB design?
A-B. An AB design is a two-part or phase design composed of a baseline ("A" phase) with no changes and a treatment or intervention ("B") phase. If there is a change then the treatment may be said to have had an effect. However, it is subject to many possible competing hypotheses, making strong conclusions difficult.
What are the 5 experimental designs used in ABA?
Six primary design types are discussed: the pre-experimental (or AB) design, the withdrawal (or ABA/ABAB) design, the multiple-baseline/multiple-probe design, the changing-criterion design, the multiple-treatment design, and the alternating treatments and adapted alternating treatments designs (see Table 2).
What is a baseline phase?
Definition. A phase of the psychophysiological assessment involving collection of initial data to help design treatment targets and assess progress over time.
Which of the following represents a primary concern with the Bab design?
Which of the following represents a primary concern with the B-A-B design? The lack of initial baseline makes it difficult to assess effectiveness.
What is a multiple treatment design?
Multi-element/alternating treatments design. -Two or more treatments are rapidly alternated; predetermined changes in conditions. -Differences in responding are a function of the stimulus/context. -Similar to the multiple reinforcement schedule used in basic research.
What are the 7 dimensions of ABA?
It is important that an individual's treatment plan has goals following these 7 dimensions: 1) Generality, 2) Effective, 3) Technological, 4) Applied, 5) Conceptually Systematic, 6) Analytic, 7) Behavioral.
How many phases are in an ABAB design?
In the ABAB design the two demonstartions are the first and second time the phase changes from baseline to treatment and in the multiple-baseline design it is after the first participants/behavior/setting and then again for the second particpant/behavior/setting.
What is baseline in therapy?
In psychological research a baseline is a measurement of the variable of interest at the beginning of treatment or a study that is used to compare to later measurements in order to judge the effectiveness of the treatment or conditions.
What is alternating treatment 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 the reversal phase of an ABAB study?
An ABAB reversal involves two conditions wherein 'A' is a baseline or no-intervention (or no manipulation) condition and 'B' is an intervention condition. Observations of a specified length (e.g., 15 min) are first conducted under the baseline condition.
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 are the advantages of an ABAB design?
The main advantage of the ABAB model is that it ends “on a positive note” with the intervention in place instead of with its withdrawal. Another advantage is that the ABAB design psychology experiment has an additional piece of experimental control with the reintroduction of the intervention at the end of the study.
