Stimulus salience refers to the prominence of a stimulus that can influence stimulus control and may depend on sensory capabilities.

• A. True
• B. False
• C. It is solely determined by frequency
• D. It has no effect on learning

Answer: (A)

Stimulus salience is about how noticeable or prominent a stimulus is to the organism, and that noticeability shapes stimulus control during learning. When a stimulus is more salient, it stands out and is more effectively associated with reinforcement, leading to faster and stronger learning and stronger control of behavior by that cue. Salience depends on sensory capabilities—what a learner can detect and discriminate. For instance, a bright light or a loud tone tends to be more salient than dimmer or softer stimuli, especially for someone with intact sensory perception. This greater salience makes the cue more influential in guiding responses and in forming clear discriminations.

Saying salience is solely determined by frequency isn’t accurate, because frequency alone doesn’t capture how noticeable a stimulus is. And claiming it has no effect on learning goes against evidence showing that more salient stimuli usually produce quicker acquisition and more robust stimulus control. So the statement is true.
