In PECS, what does the term "discriminating" refer to?

In the context of the Picture Exchange Communication System (PECS), "discriminating" specifically refers to the ability to distinguish between different communication symbols. This skill is crucial as it enables individuals using PECS to understand and select appropriate images or symbols that convey their desired message. Discrimination is necessary for effective communication, as it allows the individual to make choices from a variety of symbols, thereby enhancing their expressive language skills.

The mastery of discriminating between symbols is often a focus in the initial phases of PECS training, where the user learns to recognize that different symbols represent different items or requests. This understanding leads to more effective communication because the individual can clearly express their needs and preferences.

Other options, while related to communication, do not capture the specific meaning of "discriminating" within the framework of PECS. Recognizing social cues, recalling vocabulary, or choosing between communication methods involve different skill sets and processes that go beyond the basic function of symbol discrimination.
