Which behavioral cue indicates a change in judgment due to alcohol consumption?

The behavioral cue that indicates a change in judgment due to alcohol consumption is often linked to increased talkativeness. When individuals consume alcohol, it can cause them to feel more relaxed and sociable, leading to behavior changes, such as speaking more freely or engaging in conversation more than they typically would when sober. This increased sociability is often a reflection of impaired judgment, where individuals may become less aware of social cues or the appropriateness of their communication in various contexts.

While the other options may be associated with the effects of alcohol, they are not as directly indicative of changes in judgment. Slowed reaction time can show physical impairment but does not necessarily reflect how an individual’s decision-making ability is affected. Drowsiness is more related to lethargy than to judgment, and glassiness of the eyes is a physical sign that may suggest intoxication but does not provide insight into the person’s judgment or decision-making processes. Thus, increased talkativeness serves as a clear behavioral indicator of altered judgment due to alcohol consumption.
