Data and Graphing
When graphing, the Y-axis is the:
Ordinate (Vertical)
Several toys are placed around the room, and the client is allowed to interact freely with them. The RBT measures how long the client interacts with each toy.
What type of preference assessment is this?
Free-operant preference assessment.
An RBT says, “Touch your nose.” The client does not respond, so the RBT points to the client's nose. The client responds correctly. What type of prompt was used?
Gestural prompt
During ABC data collection, an RBT records: “Teacher says, ‘Time to clean up’ → client throws materials → teacher tells client to take a break.” Which part is the consequence?
The teacher tells the client to take a break.
How long must records be stored?
7 Years
A behavior must occur for the entire 1-minute interval for the RBT to mark the interval as an occurrence. What measurement is this?
Whole-interval recording.
A BCBA interviews a caregiver about when a client's problem behavior occurs and what typically happens afterward. What type of assessment is this?
Indirect assessment.
A client correctly identifies a picture and immediately receives praise and access to a preferred toy. What follows the behavior?
Reinforcement.
Two clients engage in completely different behaviors: one screams and another drops to the floor. Both behaviors consistently result in adults giving them attention. What do the behaviors potentially have in common?
Their function may be attention, even though their forms are different.
If an RBT is arrested, they must report it to the BACB within:
30 Days
Client A engages in 10 instances of aggression during a 2-hour session. Client B engages in 8 instances during a 30-minute session. Which client has the higher rate of aggression?
Answer: Client B.
Client A = 5 per hour
Client B = 16 per hour
An RBT records whether problem behavior occurs during specific time blocks throughout the day to identify patterns in when the behavior is most likely to occur.
What assessment tool might be useful?
A scatterplot.
During initial teaching, the RBT provides reinforcement after every correct response. What schedule is being used?
Continuous reinforcement (FR 1).
An RBT reinforces a client for appropriately requesting a break while withholding reinforcement following whining. What procedure is being used?
Differential Reinforcement of Alternative Behavior (DRA).
An RBT has been working full-time providing behavior-analytic services for a month and wants to ensure they are meeting the BACB supervision requirements. What is the minimum percentage of supervision required per month?
5%
A client responds correctly on 18 out of 20 opportunities. What percentage of opportunities were correct?
Answer: 90%.
A client repeatedly engages in hand-flapping even when no one is nearby and no obvious social consequence follows. What function might be considered?
Automatic reinforcement.
The RBT completes all steps of putting on a jacket except the final step. The client performs the final step and receives reinforcement. Once mastered, the RBT teaches the client the second-to-last step. What procedure is this?
Backward chaining.
A behavior initially increases dramatically after reinforcement is discontinued. The RBT correctly follows the behavior plan. What phenomenon may be occurring?
An extinction burst.
On the last day of the month, a grateful parent hands an RBT a $50 gift card to a local coffee shop as a thank-you for their hard work with their child. What should the RBT do according to ethical guidelines?
politely decline and explain
A graph shows aggression decreasing from 20 occurrences per session to 15, then 10, then 5. What is the overall trend?
Decreasing/downward trend.
Instead of observing every instance of a client's completed homework, the RBT counts the number of completed assignments after the session.
What measurement method could this represent?
Permanent-product recording.
If the RBT checks the handwashing routine weeks later to determine whether the client still performs it independently, what is being assessed?
Maintenance.
“First finish your worksheet, then you can play the video game.” What behavioral principle is being used?
Premack principle
Always protect a client's confidentiality and privacy is :
Client Dignity
