[U5Q] A BCBA is teaching their client how to use the toilet. She collects baseline data and determines that the potential for accidents is high. She then implements an intervention that requires the client to wear underwear instead of the diaper the client currently wears. After the BCBA puts the intervention in place, the frequency of accidents begins to decrease.  Once the client consistently uses the toilet properly and accidents are rare, the BCBA implements a differential reinforcement for alternative behavior (DRA) procedure. The frequency of accidents initially remains low but begins to increase (trend back up) after a few sessions of DRA. Which confound is most likely influencing these results?

[U5Q] Femma is a BCBA looking to increase the on-task behaviors of one of her clients. Femma uses an alternating treatment design to compare two different interventions of 5-minute and 3-minute fixed time (FT) schedules. Femma fails to randomize the order of the interventions and always follows the FT5 with the FT3. The FT3 seems to produce higher rates of on-task behaviors. Which confound is most likely to influence these results? 

[U6Q] Terry, a BCBA, is monitoring the amount of time he spends exercising. He reviews his baseline data before he implements a plan to increase the amount of time he spends exercising. Which type of analysis is Terry conducting?

[U5Q] At a vocational rehabilitation center, Samantha analyzes two different types of instruction: (a) rapidly alternating picture prompts and (b) delayed prompting across work tasks, to determine which one is most effective. She then assesses the latency to begin the task for each type of instruction. Which experimental design is Samantha using?

[U5Q] Mario is working with his client to help increase his daily living skills. After completing tasks, the client enjoys listening to music at a high volume. Mario wants to examine if music is more effective as a reinforcer when it is played at either 80, 90, or 100 decibels. Which analysis would be the best for Mario to use?

[U5Q] Joelle is conducting a functional analysis to determine the maintaining variables for her client’s eye-gouging behavior. Joelle ensures that she does not run all of the test and control conditions following her client’s mid-morning snack time by randomly assessing her client 30 minutes before or 30 minutes after snack time. What should Joelle consider when using a multielement design?
