ABA Glossary: 6th Edition TCO Reference D. Experimental Design

Sequence effects

A confounding effect on a subject’s behavior in a given condition that results from the subject’s experience with a previous condition.

Sequence effects Read More

5th Edition Task List

D-5 Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).

6th Edition TCO

D.7 Distinguish among reversal, multiple-baseline, multielement, and changing-criterion designs.

Setting confounds

Any uncontrolled variables in the treatment setting that could impact the outcomes and/or the effectiveness of an intervention and therefore the internal validity of the experiment.

D.3 Identify threats to internal validity (e.g., history, maturation).

Single-subject designs

A type of experimental design in which each subject serves as their own control, and the effects of treatment are compared to the subject’s own baseline data.

D-3 Identify the defining features of single-subject experimental designs (e.g., individuals serve as their own controls, repeated measures, prediction, verification, replication).

D.4 Identify the defining features of single-case experimental designs (e.g., individuals serve as their own controls, repeated measures, prediction, verification, replication).

Steady state responding

A pattern of stable target behavior responding over a period of time.

D.4 Identify the defining features of single-case experimental designs (e.g., individuals serve as their own controls, repeated measures, prediction, verification, replication).

A deliberate process in experimentation where the dependent variable is repeatedly exposed to the independent variable, controlling for and/or eliminating any extraneous influences on the dependent variable and achieving a

D.4 Identify the defining features of single-case experimental designs (e.g., individuals serve as their own controls, repeated measures, prediction, verification, replication).

Subject confounds

Any uncontrolled participant-related variables that may interfere with the outcomes of an intervention and therefore the internal validity of an experiment.

Systematic replication

An experimental replication of a previous study in which the researcher intentionally changes one or more features of a prior experiment.

Treatment package

An intervention plan, typically for behavior reduction, with two or more independent variables interacting simultaneously.

Type I error

When research outcomes result in a false positive, meaning they are interpreted as effective when actually they were not.

D.6 Critique and interpret data from single-case experimental designs.

Type II error

When research outcomes result in a false negative, meaning they are interpreted as ineffective when actually they were effective.

D.6 Critique and interpret data from single-case experimental designs.

Verification

Demonstrating that the independent variable alone is responsible for the effect on the dependent variable by removing the independent variable and observing the dependent variable return to baseline levels.

Warm-up effects

Refers to when initial response rates in baseline are weaker due to a subject needing to get warmed up.
