BCBA Lecture on Mand Training and Measurement
Presenter
- Heidi Light Giglio
- Board-certified behavior analyst at Brett DiNovi and Associates
Overview
- Focus on the 4th edition BACB task list sections D11: Using mand training
- Additional coverage on A01: Measuring frequency and A02: Measuring rate
Understanding Mands
- From Skinner's 1957 book:
- Mand: Behavior between a listener and a speaker
- Involves antecedent behavior consequence contingency
- Unique verbal operant with antecedent based on motivating operations (establishing/abolishing operations)
- Consequence: Contingent access to stimulus related to the motivating operation
- Form doesn't matter, function does:
- Gestures, spoken words, signs, picture exchanges, button presses, etc.
- Range and Difficulty:
- Varies per individual (e.g., vocal approximation "ba" for "ball")
- Includes single words, utterances, questions (e.g., "Where's my shoe?")
- Directed to different listeners (e.g., peers, parents)
Objectives of Mand Training
- Ensure communication is meaningful and can be reinforced by the community
- Achieve functional control of the motivating operation
- Encourage spontaneous mands (e.g., without visible prompts)
Benefits of Mand Training
- Reinforces speaker-listener relationship
- Serves as replacement behavior for maladaptive behaviors
- Supports functional communication training (e.g., for attention, breaks, sensory input)
Implementing Mand Training
- Preference Assessment
- Forced choice, pair choice, multiple stimulus assessments
- Identify items for engagement and avoidance
- Operational Definitions
- Define unprompted, prompted, and spontaneous mands
- Learner Assessment and Data Collection
- Needs assessment and choose relevant data method
- Expand mand repertoire
- Manding rate proficiency
- Manding sessions: Short sessions or throughout entire session with data collected
Data Collection and Analysis
- Collect frequency data: Unprompted, prompted, and spontaneous mands
- Graphs:
- Percent of mands (unprompted, prompted, spontaneous)
- Rate of mands per minute or hour
Contriving Opportunities for Manding
- Dependence on motivating operations
- Examples:
- Control items to deprive access
- Interrupt chain of responses
- Sample items to assess body language
- Use time delay, prompt fading, and contingent reinforcement
Reinforcement and Prompting
- Use differential reinforcement when responses are prompted
- Examples of reinforcement: Verbal praise and acknowledgment
Conclusion
- Keep an eye out for more educational videos from Brett DiNovi and Associates
- Importance of effective mand training in behavior analysis
These notes cover the main ideas and methodologies discussed during the presentation on mand training and applicable measurement techniques in behavior analysis.
