Positive Reinforcement
Example: Giving a sticker after cleaning up toys, cleaning up happens more often
Negative Reinforcement
Example: Ending a hard task when the person asks for a break, asking for a break happens more often
How to Design Reinforcement Procedures:
How to Evaluate if it’s Working
Differential Reinforcement
Use reinforcement to increase the behaviors we want and reduce the ones we don’t want, by being specific about what gets rewarded
DRA - Differential Reinforcement of Alternative Behavior
Example: Reward asking for help instead of throwing materials
DRI - Differential Reinforcement of Incompatible Behavior
Example: Reinforce sitting in a chair (can’t walk away and sit at the same time)
DRO - Differential Reinforcement of Other Behavior
Example: Give a break if the student goes 5 minutes without yelling
DRL - Differential Reinforcement of Low Rates of Behavior
Example: Praise when the student only interrupts twice in 10 mins instead of five times in 10 mins
DRH - Differential Reinforcement of High Rates of Behavior
DRD - Differential Reinforcement of Diminished Rates of Behavior
Example: Reinforce when a client screams 3 times instead of the previous time which was 5 times
With Extinction
Example: Ignore whining but reward calm requests
Without Extinction
Example: Still respond to a tantrum, but heavily reward calm asking
How to Design It:
How to Evaluate It:
Noncontingent Reinforcement (Time-Based Reinforcement)
Types of Time-Based Schedules:
Fixed-Time (FT)
Example: Every 2 minutes, give a high-five or let them play with a toy
Variable-Time (VT)
Example: On average every 3 minutes, sometimes 2, sometimes 4
Conditioned Reinforcer
Example: A token becomes valuable because it means “you’ll get a prize soon”
How to Establish Conditioned Reinforcers:
Example: Give a token, then immediately
give candy
How to Evaluate It:
Motivating Operation (MO)
Example: If a child is thirsty, juice becomes more powerful as a reward
Discriminative Stimulus (SD)
Example:
* A teacher says “Clean up” and gives a sticker for cleaning
