Discrimination training focuses on:

Discrimination training is a fundamental concept in behavioral psychology, particularly within the framework of applied behavior analysis. It specifically targets the development of the ability to distinguish between different stimuli and respond appropriately based on those distinctions. This process involves reinforcing behaviors only in the presence of a particular stimulus while not reinforcing them in the presence of other, non-target stimuli.

By focusing on understanding the differences between various stimuli, individuals can learn to respond correctly based on the context, which is critical for developing effective communication and adaptive behaviors. For example, if a child learns to identify and respond differently to a red light versus a green light, they are demonstrating a successful application of discrimination training.

The other options address topics that are not the primary focus of discrimination training. While assessing academic achievements, encouraging peer cooperation, and evaluating emotional responses are all valuable areas of study, they do not pertain specifically to the core goals and methodologies of discrimination training in behavioral contexts. This distinction clarifies why the understanding of differences between multiple stimuli is the correct answer in this context.
