The document discusses several approaches and models of disability: 1) The social model of disability sees disability as caused by social and environmental barriers rather than individual limitations. It believes society disables people by not providing equal opportunities. 2) The medical model views disability as caused by physical or mental limitations of an individual. Treatment focuses on the individual's impairment. 3) The right-based model sees disabled people as human beings with equal rights to live in society. 4) The charity model sees disability as circumstances requiring sympathy and special provisions to meet needs.
