What is Stimulus Control In Behavioral Science?

What is Stimulus Control?

Stimulus Control is a key concept in behavioral science referring to the influence that environmental stimuli have on the occurrence of a behavior. It is based on the principle that behavior can be influenced or managed by controlling the presence or absence of certain stimuli.


Stimulus Control involves the conditioning of behavior through association with specific environmental cues or stimuli. This occurs when behaviors are reliably produced in the presence of a specific stimulus, due to the history of reinforcement in the presence of that stimulus.

Key Aspects

  • Discriminative Stimulus

    A discriminative stimulus is a specific type of stimulus that is present when a behavior is reinforced. The organism learns to perform the behavior in the presence of this stimulus because it has been associated with a positive outcome or reward.

  • Behavior-Response Relationship

    Stimulus control highlights the strong relationship between environmental cues and the likelihood of a certain behavior. Behaviors are more likely to occur in situations where they have been reinforced in the past.

  • Environmental Control

    Stimulus control emphasizes the role of the environment in shaping and controlling behavior. By manipulating environmental cues, one can influence the occurrence of a behavior.

Role in Behavioral Science

In behavioral science, stimulus control provides a framework for understanding how behaviors can be influenced by environmental cues. It plays a crucial role in both operant conditioning, where behavior is reinforced or punished, and classical conditioning, where a neutral stimulus becomes associated with a significant stimulus.

Implications for Behavior Change

Understanding stimulus control can be instrumental in facilitating behavior change. It can be used to promote desired behaviors and decrease unwanted behaviors. For instance, in therapy or behavior modification programs, manipulating environmental cues can help encourage desired behaviors (such as studying in a quiet environment) and discourage undesired behaviors (such as eating unhealthy snacks when watching TV).
