DEVELOPMENTAL DISABILITIES

The three main forms of monism are physicalism, which holds that the mind consists of matter organized in a particular way; idealism, which holds that only thought truly exists and matter is merely an illusion; and neutral monism, which holds that both mind and matter are aspects of a distinct essence that is itself identical to neither of them.Disability has often been described as a physiological deficit. Current concepts of disability, however, are based on social models, which describe disability in terms of functional limitations experienced by a person because of environmental and social barriers.
