What psychological effect do depressants typically have?

Depressants are substances that typically slow down the central nervous system, leading to a variety of psychological effects. The correct response highlights that depressants primarily enhance relaxation and decrease overall activity. This effect contributes to a calming sensation, which is often sought after in stressful situations or to alleviate anxiety. By reducing the level of arousal and mental fatigue, depressants can help individuals feel more at ease and less agitated.

While other options may suggest effects commonly associated with stimulants, such as increased alertness or hyperactivity, they do not accurately reflect the nature of depressants. Additionally, the notion that depressants improve cognitive function is inaccurate, as their primary role is to slow mental processes rather than enhance them. Understanding these effects is crucial for recognizing how different substances can influence behavior and physiology.
