Lecture Notes on RBT Exam: Measurement Section

Introduction

• Lecture by Mauricio from BA Made Easy.
• Focus: Measurement section of the RBT exam.
• Recommended to watch the previous video on exam requirements and study tips before this one.
• This video is a quick review intended for listening as a summary.

A1: Prepare for Data Collection

• Preparation Steps:
  • Ensure all materials are ready (tablet, phone, data sheets).
  • Devices fully charged.
  • Know the target behaviors for the session by reviewing previous data.
  • Be familiar with all procedures for addressing behaviors.
• Priority:
  • Address risky behaviors like elopement first.
  • Have necessary tools like flashcards, reinforcers, counters, timers.

A2: Implement Continuous Measurement Procedures

• Continuous Measurement: Recording every instance of behavior.
• Types:
  • Frequency/Count: Tally every behavior occurrence.
  • Rate: Frequency over time, good for comparing sessions of different lengths.
  • Duration: Time from onset to offset of behavior.
  • Latency: Time from instruction onset to response initiation.
  • Interresponse Time (IRT): Time between successive responses, useful for adjusting response rates.

A3: Implement Discontinuous Measurement Procedures

• Discontinuous Measurement: Sampling instead of recording all behaviors.
• Types:
  • Intervals: Time divided into segments.
  • Whole Interval Recording: Behavior must occur throughout the entire interval.
  • Partial Interval Recording: Behavior occurs at least once during the interval.
  • Momentary Time Sampling: Check if behavior is occurring at specific moments, useful for large groups.

A4: Implement Permanent Product Recording Procedures

• Permanent Product: Tangible outcomes of behavior (e.g., completed assignments, holes in wall).
• Criteria:
  • Product must be solely caused by the behavior being measured.

A5: Enter Data and Update Graphs

• Data Entry Process:
  • Collect data during sessions (Discrete Trial Training).
  • Summarize data in sheets and graphs.
  • Review data for session preparation and monthly overview.

A6: Describe Behavior and Environment in Observable and Measurable Terms

• Operational Definitions:
  • Define behaviors in specific, observable terms.
  • Avoid vague terms like "upset"; specify observable actions.
  • Include clear onset and offset criteria.
• Interobserver Agreement (IOA):
  • Good definition if IOA is over 80% across observers.
