Stefanie is a speech pathologist working with Emily, who is struggling with initial sounds of words. Stefanie has decided to test the effects of an audio recorded modeling strategy with Emily. She first records the number of errors in naturally occurring speech for a three minute period, four days in a row. Next, while alternately collecting data in the form of errors per three minute period of naturally occurring speech, she introduces audio recorded modeling for twelve therapy sessions. Stefanie then collects errors per minutes of speech for four days after the intervention. Which of the following is the most critical drawback of the design Stefanie has selected?
◦ No baseline data were collected
◦ Ethics of treatment reversal
◦ Withdrawal of treatment condition
◦ Selection of experimental participant
