Single-subject research involves studying the behavior of individual subjects over time, often with repeated measurements of behavior under different conditions. This design allows for each subject to serve as their own control, which minimizes the effects of individual differences that might come into play if different subjects were used. This also means that researchers can establish a baseline for the subject's behavior before manipulating the independent variable, which makes it easier to assess the impact of the intervention. Single-subject research is particularly useful for answering questions about within-person change or individual differences in responsiveness to a particular type of treatment or intervention. However, it may not be as well-suited for answering questions about group differences or for teasing apart complex interactions between multiple factors.
