I WILL BE STUDYING WITH YOU GUYS FOR MY EXAM! with explanation I am passing first time cause this just gave me an ahaaaa moment ready for my class exam!

[@ABAExamReview]

You got this

[@kathsanchez3335]

Thank you for the explanation. Reversal and withdrawal design are so similar that I can hardly see any differences.

[@ABAExamReview]

My pleasure!

[@TheLifeofStacieJ]

I scored the highest in task list D only because of this video thank you!

[@ABAExamReview]

Nice!

[@analumedeiros4317]

Do u know your score after test?

[@IsachizTreto]

You made it so easy to understand!!!! Thank you

[@ABAExamReview]

My pleasure, happy to help!

[@celtus7]

Thank you this was extraordinarily helpful.

[@ABAExamReview]

Love to hear that

Which single subject design would you recommend if I want to increase healthy food consumption in matching law theory by implementing choice intervention.

I’m a little confused as to how you decide where the data points go for the prediction element of the baseline logic in the graph. I understand it’s at the same level with a similar trend and variability, but how do you know where specifically on the graph that they go and how many points to add? Is it just a general estimation? Thank you for your help! Great video.

[@ABAExamReview]

Hey, great question, there is no precise method for prediction. Prediction is more of a general theory that, if all things were held equal in a steady state, the behavior would more or less continue as is.

[@heeramin1942]

is there a difference between reversal and withdrawal? Or under the 5th edition task list are they now used interchangeably?

[@matteabazala]

According to the Cooper et al. (2019) text, “Some authors use the term withdrawal design to describe experiments based on an A-B-A-B analysis and reserve the term reversal design for studies in which the behavioral focus of the treatment variable is reversed (or switched to another behavior), as in the DRO and DRI/DRA reversal techniques described later in this chapter. However, reversal design, as behavior analysts most often use the term, encompasses both withdrawals and reversals of the independent variable, signifying the investigator’s attempt to demonstrate “behavioral reversibility” (Baer, Wolf, & Risley, 1968; Thompson & Iwata, 2005). Also, withdrawal design is sometimes used to describe an experiment in which the treatment variables are sequentially or partially withdrawn after their effects have been analyzed in an effort to promote maintenance of the target behavior (Rusch & Kazdin, 1981).”

Thank you! Amazing explanation

[@ABAExamReview]

Glad it was helpful!

[@ravenmendoza]

Could you do a deep dive for BCBA section d?

[@ABAExamReview]

I will make a note of this. We are developing a breakdown of each section. Be on the look out!

[@ravenmendoza]

@@ABAExamReview Is it possible before November 4th? 😅

[@ABAExamReview]

@@ravenmendoza ha, I'll see what I can do

[@ravenmendoza]

[@Gemisnotmyname]

What about ABC design? Where u have A baseline B intervention and C a new intervention?? Is this also a valid single subject design?

[@ABAExamReview]

That type of design is often used as a reversal design where you might introduce your baseline, the two interventions, and then revert back to baseline. You could also use something like that design to compare and then pick the best intervention.
