Which of the following is a potential psychological effect of alcohol consumption?

Heightened anxiety and depression risk is a well-documented psychological effect of alcohol consumption. Alcohol is a central nervous system depressant, which means that while it can initially create feelings of euphoria, its use can ultimately lead to negative emotional outcomes. Chronic alcohol consumption is linked to an increased risk of mood disorders, including anxiety and depression. This can be due to both the neurochemical changes that alcohol causes in the brain and the social and personal consequences that arise from excessive drinking.

In contrast, the other options suggest benefits or positive effects that are not consistently supported by research. For instance, while some individuals may feel a temporary improvement in mood or social behavior after drinking, these effects are generally short-lived and can lead to negative long-term consequences, such as impairment in cognitive functions and increased interpersonal issues. It's important to understand that any short-term benefits of alcohol are often overshadowed by its long-term psychological risks, particularly related to heightened anxiety and depression.
