External Validity

The degree to which the outcomes of research can be applied to different contexts and populations beyond the experimental environment.

Reversal Design

A single-subject experimental design in which behavior is measured to provide a baseline (A), then again after the treatment has been applied (B), then again after the conditions during baseline have been reintroduced (A), and then once again after the treatment is reintroduced (B). Also known as ABAB design.

Single-Subject Experiments

Research studies that focus on the response of a single subject to experimental treatments over time, allowing detailed observation of behavior changes.

Control Group

In experimental research, a group of subjects that does not receive the experimental treatment, used for comparison with the treated group.
