Throughout history, disability has been an object of scorn, stigmatisation, rejection, fascination, and also of reflection on the human condition and life in society. The difficulties are necessarily defined in relation to situations and ways of functioning that are most prevalent in society. Many cultures have seen disability as a manifestation of occult powers, punishment, or trials. For some civilisations, however, disability may confer exceptional abilities. A much more recent perspective views disability as the consequence of health problems, and focuses on their impact with the aim of remedying them through therapies and technical aids. In contrast to this medical approach, a social model considers that disability is created by society, as a result of environmental conditions that prevent full participation in society. Addressing the problem must therefore target the barriers to participation, both in the physical organisation of the environment and in ideology and culture. There is now a growing recognition that the complexity of the concept of disability arises from the interaction between the characteristics of a person (not only the components of their health) and those of the society in which they live. This perspective opens up the recognition, understanding and research of shared human experience and individual differences. Technological advances, ethical questions about human enhancement, and cultural changes point to a time when disability will no longer be a defining category-for better or for worse for people with disabilities.Children's risky play-thrilling experiences and developmental benefits
