Which of the following is NOT a typical symptom of mania?

A quiet demeanor is not characteristic of mania. Individuals experiencing a manic episode typically exhibit heightened energy levels and increased activity, leading to symptoms such as a decreased need for sleep, irritability, and impulsivity. Instead of being quiet, those in a manic state often display excessive talkativeness and a propensity to engage in various activities. Therefore, a quiet demeanor stands out as inconsistent with the typical behaviors associated with mania.
