Differential Reinforcement

Differential Reinforcement

Rachel, Scott, Mary, Bri

What is Differential Reinforcement (DR) 

• DR is an intervention that reinforces one type of behavior while putting all other responses on extinction.

• Differential reinforcement uses positive reductive procedures to reduce or eliminate interfering behavior (e.g., tantrums, aggression, self-injury, stereotypes).

Multiple Choice

Which of the following behaviors would not improve with the use of DR?

• Hitting a student

• Getting up from a seat

• Performing poorly on a math test.

• Inappropriate sensory seeking (ie. rubbing hair off head)

How does it relate to my classroom?

• General Education and Special Education classrooms:

• Gen ed/Sped classrooms all have behaviors that we as educators wish to replace.

• DR can be used in all types of classrooms and with all types of students.

Terms to know:

• Interfering Behavior

• Alternate Behavior

Procedures

• DRO-Main goal is to eliminate the interfering behavior

• DRL- Main goal is to reduce the interfering behavior

• DRI- Main goal is to substitute the interfering behavior

• DRA- Main goal is to substitute the interfering behavior

Scheduling:

• Fixed-ratio

• DRO

• DRA

Multiple Choice

Ms. Lexi is focusing on reducing the number of times Bentley goes to the water fountain during a class period. Ms. Lexi collected baseline data and it shows that Bentley gets a drink an average of 11 times per 30-minute class period.

• DRI

• DRO

• DRL

How do we implement it?

• Identify the interfering behavior.

• Collect data on the behavior.

• Determine the function of the behavior.

• Teach the alternate behavior.

• Collect data on alternate behavior.

• Reinforce when appropriate per procedure type.

• Re-evaluate after a set time frame to determine if it is working.
