PSYB45H3 Chapter Notes - Chapter 22: Internal Validity, Developmental Disability, Normative Social Influence
Document Summary
Doing behavioural modification research: dependent variable: the measure of behavior, a study or experiment is said to have internal validity if it convincingly demonstrated that the. Hence, this research design is also called an abab design. It has also been called a withdrawal design because the treatment is withdrawn during the second baseline phase. In addition, if the procedure is used with only one individual, we can conclude only that the treatment was internally valid with that individual. We must be cautious in extrapolating the results to other individuals. A multiple-baseline-across-situations design: a multiple-baseline-across-situations design involves establishing baselines for a behavior of an individual across two or more situations concurrently followed by the introduction of the treatment to the behavior sequentially across those situations. Other potential limitations are that the behavior might occur in only one situation, or there might not be sufficient observers to gather the necessary data.
