Stimulus delta (SΔ) A stimulus in the presence of which a given behavior has not produced reinforcement in the past or produces less reinforcement or lesser value reinforcement than when it occurs in the presence of the SD. 5th Edition Task ListB-10 Define and provide examples of stimulus control. 6th Edition TCOB.12 Identify examples of stimulus control. Related Content Stimulus salience The process of making learning stimuli more prominent to establish stimulus control and skill acquisition.Stimulus control When a learned behavior occurs in the presence of the SD and doesn’t occur in the absence of the SD or in the presence of other stimuli (SΔ).Overshadowing When the presence of a competing or distracting stimulus interferes with the acquisition of a skill/stimulus control of another stimulus.Overselective stimulus control When focusing on a minor feature of a stimulus interferes with stimulus control and prevents the acquisition of new skills.Masking When a stimulus has acquired stimulus control over a specific response, but a competing stimulus is present, blocking stimulus salience, and causing a decrease in the occurrence of the learned…Faulty Stimulus Control When a response occurs in the presence of an irrelevant stimulus as opposed to the relevant, trained stimulus.Discriminative stimulus (SD) A stimulus in the presence of which specific responses have been reinforced in the past and in the absence of which the same responses have not been reinforced in the…Discriminated operant A learned response under the stimulus control of an SD. Due to a history of reinforcement, that response occurs in the presence of that specific SD and not in its…Dana Do's: Discriminating Between Masking and Overshadowing PTB co-founder Dana Meller offers detailed examples to help students better discriminate between two often confusing concepts: masking vs. overshadowing.Dana Do's: Using Stimulus Salience to Increase Studying Effectiveness PTB co-founder Dana Meller discusses the ways in which you can increase your studying effectiveness through stimulus salience. We know that ABA works, and Dana reminds students to utilize basic ABA principles to help themselves prepare for the BCBA® exam.

PTB co-founder Dana Meller breaks it all down to help you discriminate between MOs, SDs, and how they work together.

Here she explains the distinction between Sᵈs and MOs, explores their evocative function, and discusses how they can alter our behavioral repertoire when combined. Through relatable examples, Dana illustrates the importance of understanding the interplay between Sᵈs and MOs in behavior change. Refer to BCBA® Task List (5th ed.)
