Quizplus · Accepted Answer

The behavior analyst is interested in testing the effectiveness of praise and prompting on different types of signs in sign language. Therefore, the baseline is being measured across different behaviors or signs, making the multiple baseline across behaviors design the most appropriate choice. This design allows for the assessment of the intervention effect across different behaviors, which strengthens the internal validity of the study. The multiple baseline design across participants or settings is not ideal in this case because the focus is on how the intervention affects different signs, rather than how it affects different individuals or settings. The concept of distance does not appear to be relevant to the question.
