5.3 Stimulus Control in Applied Settings
3 min read•august 7, 2024
Stimulus control in applied settings is all about using prompts, techniques, and environmental cues to shape behavior. It's like training a puppy, but for humans. You start with lots of guidance and gradually reduce it as the learner gets better.
This topic builds on the idea that our behavior is influenced by the stimuli around us. By manipulating these stimuli, we can encourage desired behaviors and discourage unwanted ones. It's a powerful tool for teachers, therapists, and anyone looking to change behavior.

1 of 3
- Prompts are supplementary stimuli used to increase the likelihood of a desired response
- Include verbal instructions, modeling, physical guidance, or gestures
- Fading is the gradual removal of prompts over time as the learner becomes more independent
- Ensures the learner does not become overly dependent on the prompts
- Allows the learner to respond correctly to the natural stimulus without additional assistance
Errorless Learning and Transfer of Stimulus Control
- is a teaching approach that minimizes the occurrence of incorrect responses during the learning process
- Involves providing high levels of and support initially to ensure success
- Reduces the likelihood of the learner practicing and reinforcing incorrect responses
- occurs when the learner's response shifts from being controlled by the prompt to being controlled by the natural stimulus
- Achieved through the systematic fading of prompts
- Ensures the learner can respond correctly to the natural stimulus in the absence of prompts
Antecedent Strategies
Antecedent Control and Stimulus Shaping
- involves manipulating the environment or stimuli that precede a behavior to influence its occurrence
- Includes presenting or removing certain stimuli to increase or decrease the likelihood of a specific response
- Examples: providing clear instructions, arranging materials, or adjusting the physical environment
- is the gradual modification of a stimulus to guide the learner's response toward the desired behavior
- Involves presenting stimuli that progressively resemble the target stimulus
- Helps the learner generalize their response to a broader range of stimuli
Environmental Modification and Contextual Cues
- involves altering the physical or social environment to promote desired behaviors and minimize problem behaviors
- Includes rearranging furniture, adjusting lighting, or providing visual supports (visual schedules, labels)
- Helps create a conducive learning environment and reduces distractions
- are stimuli present in the environment that signal the appropriateness of a particular behavior
- Serve as reminders or prompts for the learner to engage in the desired response
- Examples: using a specific mat for circle time, wearing an apron for cooking activities
Behavioral Chaining and Reinforcement
Behavioral Chaining
- is a teaching strategy that breaks down a complex skill into smaller, manageable steps
- Involves teaching each step of the chain separately and then linking them together
- Includes forward chaining (teaching steps in order from first to last) and backward chaining (teaching steps in reverse order)
- Allows the learner to master each component of the skill before combining them into a complete sequence
- Helps reduce frustration and increases the likelihood of success
- Examples: teaching handwashing (turning on the water, applying soap, rubbing hands, rinsing, drying) or making a sandwich (gathering ingredients, assembling the sandwich, cutting it, putting it on a plate)
Differential Reinforcement
- is a behavior modification technique that involves reinforcing desired behaviors while withholding for undesired behaviors
- Includes (DRA), incompatible behavior (DRI), and other behavior (DRO)
- Helps increase the occurrence of appropriate behaviors and decrease the occurrence of problem behaviors
- DRA reinforces a specific alternative behavior that serves the same function as the problem behavior
- Example: reinforcing a child for asking for a break instead of engaging in disruptive behavior to escape a task
- DRI reinforces a behavior that is physically incompatible with the problem behavior
- Example: reinforcing a child for sitting with hands in lap instead of engaging in hand flapping
- DRO reinforces the absence of the problem behavior during a specified time interval
- Example: reinforcing a child for not engaging in self-injurious behavior for a 5-minute period
Key Terms to Review (14)
Antecedent Control: Antecedent control refers to strategies used to manipulate environmental events or stimuli that occur before a behavior to increase the likelihood of a desired behavior and decrease unwanted behaviors. This approach focuses on modifying the situation or context that triggers certain behaviors, making it easier for individuals to engage in appropriate responses. By altering antecedents, practitioners aim to create conditions conducive to positive behavioral outcomes.
Behavioral Chaining: Behavioral chaining is a technique used in behavior analysis that involves linking together a series of individual behaviors to form a more complex behavior or skill. This process builds on the principle of reinforcement, where each step is reinforced to encourage the learner to complete the entire sequence. It emphasizes the importance of clear cues and prompts for each component of the behavior chain, making it particularly effective in teaching new skills in applied settings.
Contextual cues: Contextual cues are environmental or situational factors that can influence an individual's behavior, memory, or responses to stimuli. These cues play a crucial role in shaping how we interpret information and how memories are formed, retrieved, and utilized in various situations. Understanding contextual cues helps clarify how specific contexts can evoke different reactions or memories based on the surrounding stimuli.
Differential Reinforcement: Differential reinforcement is a behavior modification strategy that involves reinforcing a specific desired behavior while withholding reinforcement for undesired behaviors. This technique helps to increase the likelihood of the desired behavior being repeated, while decreasing the occurrence of behaviors that are not wanted. It is an essential part of various behavioral approaches and plays a critical role in establishing stimulus control and implementing applied behavior analysis in clinical settings.
Differential Reinforcement of Alternative Behavior: Differential reinforcement of alternative behavior (DRA) is a behavioral strategy that involves reinforcing a desirable alternative behavior while withholding reinforcement for an undesired behavior. This technique helps in modifying behavior by encouraging positive actions instead of merely trying to suppress negative ones. DRA is important as it focuses on teaching appropriate behaviors that can replace inappropriate ones, thereby promoting skill development and enhancing overall learning outcomes.
Differential Reinforcement of Incompatible Behavior: Differential reinforcement of incompatible behavior is a behavioral intervention strategy that involves reinforcing a specific behavior that cannot occur at the same time as an undesirable behavior. By promoting behaviors that are incompatible with the unwanted behavior, this approach effectively reduces the occurrence of that behavior while teaching and strengthening more appropriate alternatives. This strategy emphasizes the importance of using reinforcement to encourage positive behaviors while decreasing problematic ones.
Differential Reinforcement of Other Behavior: Differential reinforcement of other behavior (DRO) is a behavior modification technique used to reduce undesired behaviors by reinforcing the absence of those behaviors for a specified time period. In this approach, reinforcement is provided when the individual engages in alternative behaviors or when they refrain from the undesired behavior, promoting more adaptive responses. This method emphasizes the importance of providing positive reinforcement for other behaviors rather than solely focusing on eliminating unwanted actions.
Environmental Modification: Environmental modification refers to the systematic alteration of the environment to influence behavior through the use of various stimuli. This concept plays a significant role in applied settings where changes in surroundings are designed to promote desired behaviors, enhance learning, or discourage maladaptive behaviors. By manipulating environmental factors, such as lighting, layout, or sensory inputs, practitioners can create conditions that reinforce specific responses or learning outcomes.
Errorless Learning: Errorless learning is a teaching method designed to minimize mistakes during the learning process by providing prompts and cues that guide learners towards the correct response without allowing them to make errors. This approach helps build confidence and enhances retention, as it focuses on reinforcing successful responses rather than correcting mistakes. By preventing errors, this technique can facilitate faster and more efficient learning outcomes.
Fading: Fading is a gradual process used in behavior modification where prompts or cues are systematically removed to encourage the subject to respond independently. This technique helps to shift the control of behavior from external prompts to internal cues, which is essential for developing long-term behavior change. By decreasing reliance on prompts, fading facilitates the establishment of desired behaviors in natural settings.
Prompting: Prompting refers to a technique used in behavior modification that involves providing cues or hints to encourage a desired response or behavior. It plays a crucial role in shaping behavior by helping individuals learn new skills or reinforce existing ones through varying levels of assistance. This concept is foundational in behavioral interventions, particularly when establishing stimulus control, managing reinforcement and punishment, and applying behavior analysis in clinical settings.
Reinforcement: Reinforcement is a fundamental concept in learning that refers to any event or stimulus that increases the likelihood of a behavior being repeated. It plays a crucial role in shaping behaviors by encouraging individuals to repeat actions that lead to positive outcomes, while discouraging those that result in negative outcomes.
Stimulus Shaping: Stimulus shaping is a behavioral technique that involves gradually modifying the characteristics of a stimulus to evoke a desired response. This process allows individuals to learn and adapt by breaking down complex behaviors into simpler steps, reinforcing each step along the way. By systematically altering the stimuli in small increments, this method fosters greater control over behavior and enhances learning outcomes in various applied settings.
Transfer of Stimulus Control: Transfer of stimulus control occurs when a previously established stimulus is replaced by a new stimulus, leading to similar behavior patterns in response to the new stimulus. This process is essential for understanding how individuals learn to respond to different cues in their environment, allowing them to generalize learned behaviors to new situations while still maintaining the effectiveness of those responses. The concept emphasizes the importance of stimuli in guiding behavior and how changes in these stimuli can influence the learning process.
