[MidA] During a staff training, the behavior analyst (BA) teaches the task-analyzed skill of conducting a preference assessment. The BA asks for a volunteer to help demonstrate, and a participant, Gavin, raises his hand. The BA asks Gavin to come to the front while she demonstrates the skill. She then asks Gavin to demonstrate the skill while she provides prompts and to practice with feedback in front of the class. After the demonstration, the BA conducts a pretest of each participant’s percent of accurate steps on the skill without additional prompts or practice. Next, she provides training using prompts and practice with feedback, followed by another skill test post-training. The BA noticed that Gavin scored higher than most other participants on his pre-test and post-test. This difference in test performance between Gavin and the other participants is most likely an example of what type of threat to internal validity?
