Select the name of the experimental tactic described: this design is widely used in applied behavior analysis due to its ability to expose variables for what they are – strong and reliable or weak and unstable. the behavior analyst is able to turn on and off the behavior of interest through repeated applications of the independent

ABAB design

Explanation:

This method used in the field of research on Behavior Modification consists of four phases:

1. Phase A: Stable patient.

2. Phase B: Introduction of treatment.

3. Second Phase A: Withdrawal of treatment before consolidation.

4. Second Phase B: Reintroduction of treatment

This allows to verify the reliability of the change produced by the treatment. If it produces a new behavior change, we would have more evidence that the cause of the change is treatment.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
