What is the primary focus of discrimination training?

Discrimination training primarily involves reinforcing a specific response when a particular stimulus is present while not reinforcing that response in the presence of other stimuli. This process helps an individual learn to distinguish between different stimuli and respond appropriately based on the context.

The correct answer focuses on the idea that specific behaviors are reinforced in the presence of one stimulus, which facilitates the learning process of recognizing that behavior is context-dependent. For example, a child might learn to say "please" when requesting a toy from their parent while not engaging in that same behavior when asking a sibling. The goal is to strengthen the correct response in a designated situation while minimizing or extinguishing the response in other contexts that lack the reinforcement, thus highlighting the importance of the environment in shaping behavior.

In this framework, the other options do not align with the principles of discrimination training. Reinforcing a response in the presence of all stimuli or extinguishing behaviors in all situations does not allow for nuanced learning based on context. Reinforcing a response only in the absence of stimuli misrepresents the core objective of discrimination training, which is all about recognizing and responding differently based on specific cues.
