Final answer:
The student's query displays powerless speech mannerisms, which are indicative of a lack of assertiveness and may affect the perception of the speaker's confidence or authority.
Step-by-step explanation:
The phrases provided by the student demonstrate powerless speech mannerisms. These are characteristics in speech such as hesitations, qualifications, and hedges that can convey uncertainty or deference. In this example, words like “uh” and “I guess”, coupled with the request for an extension and ending with “OK?”, can be interpreted as signs of the speaker lacking power or being less assertive. Powerless speech mannerisms often contrast with more assertive language, which tends to be direct and confident. The text cited also speaks to the phenomenon of language ideologies, which may include beliefs about how certain genders communicate, suggesting that these ideologies can affect perceptions of language use.
