| Term | Definition |
|---|---|
| A-B design | A two-phase experimental design consisting of a pre-treatment baseline condition (A) followed by a treatment condition (B) |
| A-B-A-B reversal design | A research design consisting of a baseline and treatment phase followed by withdrawal of treatment (the second baseline) and a second implementation of the treatment |
| Abscissa | X-axis of the graph |
| Alternating-treatments design (ATD) | A research design in which baseline and treatment conditions (or two treatment conditions) are conducted in rapid succession and compared with each other within the same time period |
| Baseline | The label most often given to the no-treatment phase |
| Changing-criterion design | An experimental Design in which an initial baseline phase is followed by a series of treatment phases consisting of successive and gradually changing criteria for reinforcement or punishment |
| Dependent variable (DV) | The target behavior |
| Functional relationship | A relationship between a behavior and an environmental event (or events) in which the occurrence of the behavior is controlled by the occurrence of the environmental event |
| Graph | A visual representation of the occurrence of a behavior over time |
| Independent variable (IV) | Is what the researcher manipulates to produce a change in the target behavior |
| Multiple baseline across setting design | A multiple baseline design in which the treatment variable is applied to the same behavior of the same subject across two or more different settings |
| Multiple-baseline-across-subjects design | A multiple baseline design in which the treatment variable is applied to the same behavior of two or more subjects (or groups) in the same setting |
| Ordinate | Y-axis on a graph |
| Research design | Used to determine whether the treatment was responsible for the observed change in the target behavior and to rule out the possibility that extraneous variables caused the behavior to change |
| Extraneous/Confounding Variables | Any event that the researcher did not plan that may have affected the behavior |
| Replication | Duplication of earlier conditions in an experiment |
| Phase changing lines | Vertical lines separating experimental conditions |
| Phase labels | Descriptions of experimental conditions |
| Frequency plot | Each data-point value is graphed separately |
| Cumulative record | Each data point value is added to the previous value |
| Multiple-baseline-across-behaviors design | A multiple baseline design in which the treatment variable is applied to two or more different behaviors of the same subject in the same setting |
