The document discusses different aspects of timeout as a behavior modification technique. It defines timeout as removing a child from reinforcing stimuli when they display undesirable behavior. The history section notes that the concept was first invented and used by Arthur Staats in the 1960s. There are three main types of timeout: non-exclusionary (child remains in class but can't participate), exclusion (removed to another part of the room), and isolation (removed to another room). Effective timeout involves giving warnings, having a set place and duration (usually 1 minute per year of age), using a timer, and allowing the child to redeem themselves after.
