Definition:
Psychomotor retardation is a visible slowing of physical activity such as movement and speech having a mental, not organic, cause. It is often a characteristic of clinical depression or bipolar depression.

Examples may include slow talking or long pauses before beginning to talk, taking a long time to cross a room or slow chewing of food and waiting longer than usual between bites.
