Final answer:
The study of word order, verb tense, noun case, and pronoun person falls under the field of linguistic structures, especially grammar and syntax, and is key in the context of language acquisition and analysis of language-related cognitive issues.
Step-by-step explanation:
The area concerning issues such as word order, verb tense, noun case, and pronoun person pertains to the study of linguistic structures, specifically grammar and syntax. This field explores how language is constructed to communicate meaning effectively and is a fundamental aspect of language acquisition and usage. Understanding these components is crucial, not only in general communication but also in analyzing language impairments like aphasias, where there might be a V impairment (verb deficit) or N impairment (noun deficit), which can be linked to damage in specific cortical areas of the brain. Language's influence on thought and cognition is also a significant area of research within psychology.
