Stimulus control is like a bossy traffic light for our behavior. Just like how a traffic light tells cars when to stop and go, stimulus control tells us when to do certain things based on cues or signals in our environment. These cues can be anything from a smell, a sound, a sight, or even a thought. For example, when you hear your alarm clock in the morning, it's like a cue that tells you to wake up. So, stimulus control is all about how these cues influence and control what we do.
