Wait, what is an SD?

Have you ever noticed that some things in life seem to reliably lead to positive outcomes while others don't? Maybe you've noticed that studying for an exam tends to result in a good grade or that putting in extra effort at work can lead to a promotion or raise. These are examples of discriminative stimuli, or SDs, at work in your life.

Put simply, an SD is a cue or signal that predicts reinforcement or a positive outcome. In other words, when you encounter an SD, you know that if you engage in a certain behavior or response, you are likely to be rewarded in some way.

Think of it like a traffic light - when you see the green light, you know that it's safe to proceed and that you'll make it to your destination. The green light is the SD in this scenario, and the reinforcement is reaching your destination safely and on time.

In the world of psychology and behavior analysis, SDs are a crucial component of learning and behavior change. By identifying the SDs that are associated with positive outcomes, we can create environments that promote and reinforce desired behaviors. This can be especially helpful when working with individuals who have behavioral challenges or learning needs.

For example, a teacher might use an SD, like a picture of a book, to signal to a student that it's time to start reading. If the student responds by picking up the book and starting to read, they are likely to be reinforced with praise or a good grade. Over time, the student will come to associate the picture of the book with the positive outcome of reinforcement, making it more likely that they will engage in the desired behavior in the future.

So, the next time you find yourself engaging in a behavior that reliably leads to an increase in that behavior (and hopefully) a positive outcome, remember that you're responding to an SD. By identifying and utilizing these cues in our lives and in our interactions with others, we can promote positive behaviors and create environments that support learning and growth.

In ABA terms: a discriminative stimulus (SD) is a stimulus that predicts reinforcement. It is traditionally written with an uppercase S followed by an uppercase D and is written as an exponent to the S. We have modeled our logo after this foundational element of behavior analysis. It also is a shout-out to our founder Dr. Shelby Dorsey whose initials just happen to be SD.'s logo also includes three data points trending upward in hopes of continuing the upward trend of our endeavors.
