Identifying perception behaviours in people with profound intellectual and multiple disabilities.

Background: To support people with profound intellectual and multiple disabilities (PIMD), it is essential to understand how they experience their environment. Insight into perception behaviour may provide an entry point for improved understanding.

Materials And Methods: A random sample of a 30-min video registration of five participants with PIMD was used to code behaviours per second based on an ethogram containing 157 different perception behaviours in nine categories.
