BACB BCABA Exam - Topic 6 Question 116 Discussion

Three boys with autism, ages 7--10 years old, served as participants in a study. During baseline, staff used response blocking when five instances of aggression or head-banging occurred within 10 seconds, until attempts ceased for 1 minute. During baseline and treatment, each occurrence of aggression and head-banging was recorded daily and converted to the number of responses per hour. Treatment comprised a differential reinforcement of incompatible behavior (DRI) schedule coupled with response blocking after every head-banging or aggression. The staff initially applied the treatment to head-banging, while continuing to take a baseline on aggression.After noting treatment effects on head-banging, the staff then applied the treatment to aggression.In this scenario, how was direct replication shown?
D) The intervention was implemented in a staggered fashion across target behaviors after the initial baseline.
A) Baseline and intervention conditions were included.
B) A baseline condition was implemented.
C) A changing criterion design was used wherein the criterion for reinforcement was gradually changed over time.

Three boys with autism, ages 7--10 years old, served as participants in a study. During baseline, staff used response blocking when five instances of aggression or head-banging occurred within 10 seconds, until attempts ceased for 1 minute. During baseline and treatment, each occurrence of aggression and head-banging was recorded daily and converted to the number of responses per hour. Treatment comprised a differential reinforcement of incompatible behavior (DRI) schedule coupled with response blocking after every head-banging or aggression. The staff initially applied the treatment to head-banging, while continuing to take a baseline on aggression.

After noting treatment effects on head-banging, the staff then applied the treatment to aggression.

In this scenario, how was direct replication shown?

Sounds a bit too simple, but I guess it works!

Wait, are we sure it’s not just the baseline that matters?

Definitely option D, they applied the treatment to different behaviors over time.

I think direct replication is shown by the staggered intervention.

I recall that direct replication can also involve applying the same treatment to different behaviors, which sounds like what D is saying.

I’m a bit lost on this one. I thought direct replication was just about having a baseline and intervention, so maybe A?

I’m not entirely sure, but I think the staggered implementation of the intervention across behaviors shows direct replication. It seems like a similar practice question we did.

I remember that direct replication involves repeating the same procedures to see if the results are consistent. I think it might relate to option D.

Direct replication is shown by the fact that the intervention was applied to both head-banging and aggression, with the staff first implementing it for head-banging and then applying it to aggression. This staggered implementation is a key feature of direct replication.

I'm a bit confused about the different design elements mentioned. I'll need to carefully re-read the question and think through the options to determine which one best represents direct replication.

Okay, let me think this through. I know a baseline condition was implemented, and the intervention was applied in a staggered fashion across the target behaviors. That sounds like the right approach.

Hmm, this seems like a pretty straightforward question. The key is to identify the design elements that demonstrate direct replication.

The staggered implementation of the intervention across target behaviors seems to be the key to direct replication here. Makes sense to me.
