Definition
The High Probability Request Sequence is a behavioral intervention strategy where a series of high-probability (easy and frequently complied-with) requests are given to a learner, followed by a low-probability (less likely to be complied-with) request. The intent is to build momentum and increase compliance with the more difficult or less preferred task by reinforcing the easy responses with praise or other reinforcers before presenting the difficult request.
Example
A teacher asks a student to complete three easy tasks in quick succession, such as “touch your nose,” “clap your hands,” and “stand up.” After the student complies with these simple requests, the teacher then asks the student to complete a more challenging task, such as “finish your math worksheet.” By building a pattern of compliance, the student is more likely to follow through with the low-probability request.
