Single-subject experimental designs typically involve multiple treatment phases to demonstrate change due to the independent variable. Additionally, these designs involve collection of data over time, making them longitudinal in nature rather than cross-sectional. While they may involve collection of data points before and after interventions, this is not the defining feature of these designs. Finally, single-subject experimental designs typically do not produce findings that can be easily generalized to other individuals or situations, as they are based on the unique characteristics of the individual participant and the specific intervention being studied.
