What term describes the prominence of a stimulus in the environment that can affect stimulus control and may depend on sensory capabilities?

• A. Stimulus salience
• B. Stimulus generalization
• C. Stimulus discrimination
• D. Response prompt

Answer: (A)

Prominence of a stimulus in the environment, or how much it stands out, governs how strongly that stimulus controls behavior. This salience depends on sensory capabilities—if an organism can detect the stimulus well, it becomes highly salient and exerts strong stimulus control; if detection is limited, the stimulus is less salient and has weaker control. This helps explain why certain cues reliably guide responses while others don’t, and why increasing a cue’s intensity, brightness, or novelty can make it more influential. It’s different from stimulus generalization, where similar stimuli elicit similar responses, and from stimulus discrimination, where you learn to respond to one stimulus but not another. A response prompt is an instructional cue added to help produce the correct response, not about how environmental features naturally control behavior.
