Vizi Exam Prep 1. Samar's BCBA wanted a way to describe the damage that their client was doing to themself with the self-injurious behaviors they exhibited. The client was prone to pinching their arms with the thumb and forefinger. The BCBA instructed the behavior therapists to record the pinching as "leaves no mark," "leaves a slight pink mark," "leaves a bright red mark," and "draws blood." The BCBA wanted the therapists to record a measure of what for them? a. Duration b. Topography – Incorrect (my answer) c. Count d. Magnitude - Correct i. Although the descriptions used are slightly different and show magnitude, they describe the same behavior of pinching. The topography of the behavior is pinching. 2. Matthew is a 6th grade student who attends general education classes but has a history of difficulties during transitions to and from school and within the school (e.g., classroom to classroom). Matthew's attendance is inconsistent. Sometimes, they are late to school and at other times they leave early. The BCBA at the school wants to collect data on Matthew's appropriate transitions during the school day. What is the best measurement system to use to collect these data? a. Frequency – incorrect i. Frequency would not give the BCBA an accurate measure because the number of transitions vary from day to day due to Matthew’s attendance. b. Permanent Product c. Percentage – correct i. Because Matthew's number of transitions vary from day to day due to attendance, a percentage of appropriate transitions per day would give the BCBA the most accurate measure. d. Rate
3. Which of the following methods can be used to derive trials to criterion data? a. Whole interval b. Momentary Time Sampling c. Partial Interval d. Latency – Correct! i. The following methods can all be used in order to derive data for trials to criterion: Count, rate, duration, and latency. 4. What type of measurement is occurring when the behavior that a BCBA is measuring is different than the behavior of interest? a. Continuous measurement b. Discontinuous measurement c. Indirect Measurement – correct! i. Indirect measurement involves measuring other behaviors that give you information about the behavior of interest, without measuring the behavior of interest directly. Some examples include: interviews, surveys, report of others. d. Calibration 5. A teacher presents a student with a worksheet of 100 multiplication problems with no restrictions on time to complete it. What would be the best way to report the results of the worksheet? a. Rate b. Percentage – Incorrect i. Although the teacher is likely to calculate the percentage of correct responses, percentages are an indirect measurement of performance. Number of problems completed correctly is a direct measurement. c. Duration d. Number of problems completed correctly – correct i. The teacher needs to know the number of items that the student has correctly completed (not just the number completed). Number of problems completed correctly is a more direct measurement than percentage.
