Scenario: John, a 19-year-old with intellectual disability, works at Starbucks as a cashier.
Issue: John takes too long to respond to customers (longest response time was 12 seconds).
Goal: Reduce the time between customer's statement (SD) and John's response.
Focused Dimension: Latency, which is the time between a stimulus (SD) and the response.
Question 2: Establishing Contingencies
Scenario: Thanksgiving meal. John's mom insists he must eat green beans to have pumpkin pie.
Establishment: A contingency is being set, as seen in the "if-then" statement (if no green beans, then no pie).
Not a Punisher or Antecedent: It's a consequence setup.
Question 3: Replacement Behaviors
Concept: Removing a problem behavior requires replacing it with behavior serving the same function.
Term: Fair Pair Rule - when reducing a behavior, target another for increase.
Question 4: Dimension of Behavior Analysis
Scenario: Sally conducts parent training with non-technical language, adhering to ABA principles.
Dimension: Conceptually Systematic - following ABA principles in a non-technical manner.
Question 5: Advantage of Multiple Baseline Design
Research Design: Useful for observing changes across settings, participants, or behaviors.
Advantage: Establish experimental control without reversing the intervention.
Question 6: Measurement Procedure for a Waiter
Scenario: Measuring time between taking consecutive orders.
Best Measure: Inter-response Time (IRT) - time between responses.
Question 7: Explaining Changes in Joe's Behavior
Scenario: Joe's reinforcement schedule changes from FR4 to VR3.
Explanation: Ratio Strain - due to less frequent reinforcement.
Question 8: Reducing Maladaptive Behaviors
Scenario: Zach's behaviors occur consistently regardless of setting.
Best Approach: Reinforce absence of problem behaviors (DRO - Differential Reinforcement of Other behavior).
Question 9: Direct Instruction Classroom
Teaching Method: Direct instruction is characterized by fast-paced teaching and grouping based on skills.
Description: Frequent assessment and grouping based on those assessments.
Question 10: Verbal Operant Identification
Scenario: Dan reacts to a football play by yelling.
Verbal Operant: Tact - it's evoked by a nonverbal SD (the play observed on the field).
Note:
Study Tips: For BCBA exams, focus on understanding concepts thoroughly, reading all answer choices, and being aware of what evokes and reinforces verbal operants.
