1.4 Purpose of Single-Subject Research

Single-subject research is usually conducted with one participant at a time, and we measure that participant’s behavior under different conditions. This way, we can evaluate if – and how much – an intervention changes that individual’s behavior. Here are some examples of questions we can try to answer using single-subject research.

Purpose of Single-Subject Research:

Does an INTERVENTION cause a change in BEHAVIOR?

Will single-subject research determine if my roommate will make dinner more often based on the purpose of washing the dishes?
Conducting a single-subject research to determine if providing the student with books that match her reading level will serve the purpose of increasing her engagement in free reading.
