A-B designA two-phase experimental design consisting of a pretreatment baseline condition (A) followed by a treatment condition (B). Show
A-B-A designA three-phase experimental design consisting of an initial baseline phase (A) until steady state responding (or counter-therapeutic trend) is obtained, an intervention phase in which the treatment condition (B) is implemented until the behavior has changed and steady state responding is obtained, and a return to baseline conditions (A) by withdrawing the independent variable to see whether responding “reverses” to levels observed in the initial baseline phase. A-B-A-B designAn experimental design consisting of (1) an initial baseline phase (A) until steady state responding (or counter-therapeutic trend) is obtained, (2) an initial intervention phase in which the treatment variable (B) is implemented until the behavior has changed and steady state responding is obtained, (3) a return to baseline conditions (A) by withdrawing the independent variable to see whether responding “reverses” to levels observed in the initial baseline phase, and (4) a second intervention phase (B) to see whether initial treatment effects are replicated. ABC Recording aka: Anecdotal ObservationA form of direct continuous observation, in which the observer records a descriptive account for all behaviors of interest and antecedents and consequences of that behavior. Abative EffectA decrease in the current frequency of behavior that has been reinforced by some stimulus, object or event, whose reinforcing effectiveness depends on the same motivating operation. Abolishing OperationA motivating operation that decreases the reinforcing effectiveness of a stimulus, object, or event. AccuracyThe extent to which observed values, the data produced by measuring an event, match the true values of an event as it exists in nature. Add-in component analysisA method for conducting a component analysis in which components are assessed individually or in combination before the complete treatment package is presented. The add-in method can identify sufficient components. Sequence and floor or ceiling effects may mask the effects of components added in toward the end of the analysis Adjunctive BehaviorBehavior that occurs as a collateral effect of a schedule of reinforcement. Schedule-induced behavior brought about by schedules of reinforcement, when reinforcement is not likely to be delivered. Affirmation of the ConsequentA three step form of reasoning that begins with a true antecedent-consequent (if- A-then-B) statement and proceeds as follows: (1)If A is true, then B is true; (2) B is found to be true; (3) therefore; A is true. Although other factors could be responsible for the truthfulness of A, a sound experiment affirms several if- A-then-B possibilities, each one reducing the likelihood of factors other than the independent variable being responsible for the observed changes in behavior. Applied Behavior AnalysisThe science in which tactics derived from the principles of behavior are applied to improve socially significant behavior. Experimentation is used to identify the variables for the improvement in behavior
