What was a wooden punishment collar used for?

A wooden punishment collar, often referred to as a "punishment yoke" or "wooden collar," was historically used as a form of public humiliation and discipline for wrongdoers, particularly in the context of schools or prisons. It would be placed around a person's neck and secured, rendering them immobile and publicly displaying them for their misdeeds. This method aimed to deter others from similar behavior by showcasing the consequences of misconduct. It was primarily used in earlier centuries before more modern and humane forms of punishment were developed.
