Punding

Punding is compulsive performance of repetitive, mechanical tasks, such as assembling and disassembling, collecting, or sorting objects. It can also apply to digital objects, such as computer files and data. The term was originally coined to describe complex, prolonged, purposeless (unproductive), and stereotyped behaviour in phenmetrazine and chronic amphetamine users, by Swedish forensic psychiatrist G. Rylander, in 1968.[1] It was later described in Parkinson's disease,[2][3] but mainly in cases of patients being treated with dopaminergic drugs.[4] It has also been described in methamphetamine and cocaine users, as well as in some patients with gambling addictions, and hypersexuality.[5]

For example, punding may consist of activities such as collecting pebbles and lining them up as perfectly as possible; disassembling and reassembling wristwatches; or conducting extended monologues devoid of context.[6]

People engaging in punding find immersion in such activities comforting, even when it serves no purpose, and generally find it very frustrating to be diverted from them. They are not generally aware that there is a compulsive element, but will continue even when they have good reason to stop. Rylander describes a burglar who started punding and could not stop, even though he was suffering from an increasing apprehension of being caught.[7] Interrupting can lead to various responses, including anger or rage, sometimes to the point of violence.[8]
