Which of the following is NOT a type of language impairment?

The correct choice indicates that excessive language disorders are not recognized as a formal type of language impairment. In the field of language disorders, there are specific categories that have been identified through research and clinical practice, such as phonological disorders, expressive language disorders, and mixed receptive-expressive language disorders.

Phonological disorders involve difficulty with the sound system of the language, affecting a person's ability to produce and discriminate between sounds. Expressive language disorders focus on challenges in the ability to convey thoughts and ideas verbally. Mixed receptive-expressive language disorders encompass difficulties in both understanding and using spoken language effectively.

In contrast, the term "excessive language disorders" lacks a clear definition within established frameworks of language impairment and does not align with recognized categories in the literature. This distinction helps to clarify why excessive language disorders are not considered a type of language impairment.
