Conversely, when the stimulus is absent or when an S-delta is present (a signal that reinforcement is not available), responses are less likely to happen.
Example:
Imagine you’re hungry, and you spot an illuminated “Open” sign at McDonald’s. In this case, the “Open” sign acts as the SD, signaling that reinforcement (getting food) is available. You’re more likely to enter and order food because the SD indicates a potential reward. Now, if there were a “Closed” sign, this would serve as the S-delta, indicating that no food is available. As a result, you’re less likely to enter the restaurant.

The response remains consistent, even though the stimuli may vary slightly.
Example:
Let’s say you’ve taught a child to say “apple” when they see a picture of an apple. After mastering this skill, they start saying “apple” when they see a real apple. Although the stimuli are different (a picture vs. a real apple), the response is the same. This is stimulus generalizationGeneralization refers to the ability of a learner to apply a..., as the child has learned to apply the response to both stimuli.

Response Generalization is different from stimulus generalization. It occurs when a single stimulus elicits various responses. The stimulus remains constant, but the behaviorBehavior refers to any activity or action that living organ... or response changes.
Example:
Consider teaching a child to build a castle with building blocks. Later, when given the same blocks, the child decides to build a house instead. Here, the blocks are the same, but the child’s response has shifted, showing response generalization.

Later, when the teacher reduces the frequencyFrequency or Count is a simple measure of how often a par... of praise, the students continue to respond correctly at the same levelIn Applied Behavior Analysis (ABA), level refers to the valu.... This shows response maintenance because the behavior persists even when reinforcement has been diminished.
Conclusion
Understanding concepts such as Stimulus Discrimination, Stimulus Generalization, Response Generalization, and Response Maintenance is critical in behavior analysis. These principles help explain how behaviors are shaped, adapted, and sustained over time, allowing practitioners to develop more effectiveEffective refers to one of the seven dimensions of Applied... intervention strategies.
