What is 'punding'?

• A. Feeling the sensation of bugs crawling underneath one's skin
• B. Being unable to go to sleep
• C. Experiencing withdrawal symptoms after long-term, high-dose amphetamine abuse
• D. Engaging in a specific activity compulsively and repetitively, repeatedly

Answer: (D)

Punding is a repetitive, compulsive, non-goal-directed pattern of behavior. People engage in a specific task over and over for long periods, often focusing on mechanical details or arranging objects, with little or no practical purpose beyond the act itself. This phenomenon is frequently observed in individuals with heavy, long-term stimulant use, such as amphetamines, where dopamine-related brain circuits can drive these stereotyped, aimless actions.

It isn’t the sensation of bugs crawling under the skin—that describes formication or paresthesia. It isn’t about not being able to sleep, which would be insomnia. It isn’t a withdrawal symptom after stopping long-term amphetamine use. The defining idea here is the compulsive, repetitive engagement in a single activity that serves no meaningful external goal.
