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.
Conducting single-subject research by spraying your cat with water when she scratches the couch serves the purpose of reducing her scratching behavior.

I agree that interventions can produce meaningful changes in behavior, but their effectiveness is not determined by the intervention alone. The relationship between the person implementing the intervention and the individual receiving it can play a significant role in how well it works. When there is trust and familiarity the individual may be more willing to accept feedback, comply with expectations, or remain motivated to engage in the behavior process.

I agree, Intervention helps behavior by introducing structured strategies that encourage positive actions and reduce problematic ones. Over time, consistent intervention can lead to lasting behavioral change by reinforcing desirable patterns.

I learned that single-subject research helps us see whether an intervention actually changes a person’s behavior. By observing one person over time ,it becomes easier to understand if the intervention is making a difference .

Subject motivation is a much larger factor than I would have thought. I have attempted to design some interventions for different behavioural change at work and if subjects are not motivated to change their behaviour, it will not happen.

the behavioral changes that are at play are designed for intervention but also the subjects don’t have motivation for changing their behavior until it comes about. But when theirs change it will help the persons behavior

I believe that intervention does cause a change in behavior depending on what types of reinforcements and circumstances are used to help the person improve the behavior.

Intervention can have a big impact on behavior. I also think it is important to consider the individual person because what works for one person may not work for another. Motivation and positive reinforcement can make an intervention much more effective.

I believe that if an intervention is identified and implemented with fidelity, while taking into account a desired reinforcer, it can truly make a difference. I do agree with the posts before about the relationship factor of the person providing the intervention as well. It does make a difference if rapport is established with the student.

I believe an intervention can impact or change behavior; however, it must be implemented with fidelity and be well thought out to make a change.
