and control the use of knowledge and language often pathologize other humans because of their particular intellectual, physical, and genetic characteristics. However, even deeply rooted and accepted truths can be challenged. New social constructions are born as those who have been objectified by dominant ways of seeing and knowing speak back and challenge so-called truths that do not actually reflect their own ways of seeing themselves—often experienced as violations to their dignity and equal respect. This is certainly the case as women, ethnoracial, and sexual minorities challenge dominant gendered, sexist, racialized, and heteronormative labels and categories. Similarly, people with intellectual and developmental disabilities, and their advocates, increasingly challenge the idea that intellectual and developmental disabilities are by definition “deficits” or “impairments,” and instead some are beginning to call for recognition of “cognitive diversity.” Around the world, people with intellectual and developmental disabilities and their families are calling for an end to poverty and exclusion, for a right to live in communities outside of institutional care, for full inclusion in quality education, and for the right to have their legal capacity and decisions over their own lives respected, including the right to vote, to marry, and to control their own bodies and their own property (Inclusion Interna-
bodies and their own property (Inclusion International, 2006, 2009, 2012, 2014). In this respect, legitimate knowledge about disabilities emerges from the diverse voices of people with disabilities themselves rather than from others talking about them. These and other views may seem to compete with one another, and indeed many do, but each represents its own “truth” about how disabilities are understood. Together, these views aid understanding that intellectual or developmental disability is not a fixed and absolute fact or feature of a person. It is a human-made lens shaped through culture, law, and political struggles throughout history (Carlson, 2010). The starting point is to recognize, as critical theorists in this area have done since the latter part of the 20th century, that intellectual or developmental disability—or one of its predecessor categories such as mental retardation, mental deficiency, or

Determinations of incompetency to manage one’s estate or person were made by jury trials at inquisitions called for the purpose. These determinations were the purview of the courts and juries exclusively, but they acted on the royal prerogative— the parens patriae power (Neugebauer, 1996). As Foucault (1965) argued, it was from the 14th century on that reason and rationality became the defining feature of what it meant to be a person, and culture, science, and public policy since that time rests largely on this assumption. Development of statutory law during this period suggests that what reason comes to mean is constructed in tandem with the legal
during this period suggests that what reason comes to mean is constructed in tandem with the legal articulation of lunacy and idiocy. State obligations to people with a disability were consolidated in England with the passage of the Poor Law in 1601 (Hirst & Michael, 2003; King, 2000; Rushton, 1988). This statute established a distinction between the “worthy” and the “unworthy” poor and was later adopted in many of England’s colonies. Adults with disabilities considered unable to work were, by this law, deemed worthy and entitled to state provision. The law contributed to a marginalized economic and social status for people with disabilities that still continues. By linking disability and inability to work, the law and its ensuing amendments institutionalized the idea that people with disabilities did not fit into the labor market, an assumption that still drives much employmentrelated policy. In addition, by considering people with disabilities as “worthy poor,” the state promised slightly better provision than for the “unworthy” poor—those who were deemed able-minded and able-bodied but unwilling to work. However, the cost of obtaining richer provision was the adoption of disability as a legally sanctioned charity status, one that people with disabilities are still trying

38 committal to institutions. The growing medical profession was called upon to play this regulatory role and, over the 18th and 19th centuries, the powers to determine competence shifted from juries of inquisition under the courts to physicians. By the end of the 18th century, the Royal College of Physicians in England was responsible for the licensing of “madhouses.” By mid-19th century, resident physicians were required in madhouses of more than 100 people. In the same period, the Association of Medical Officers of Hospitals for the Insane was established, and the organization published a diagnostic manual that included such categories as “mania,” “melancholy,” “monomania,” “dementia,” “moral insanity,” “idiocy,” “imbecility,” “general paralysis,” and “epilepsy” (Weistubb, 1990). The manual is one of the precursors of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (American Psychiatric Association, 2013), widely used to “diagnose” intel-
precursors of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (American Psychiatric Association, 2013), widely used to “diagnose” intellectual, developmental, and other disabilities. The idea that disability was not a status that was conferred, but was in fact an individual deficit, gained strength in the early 20th century when Binet and Simon developed the first intelligence test to identify children in France who were not progressing in school. The test was adapted and, increasingly over the 20th century, became the most common instrument for diagnosing “feeble-mindedness,” “mental deficiency,” and “mental retardation.” Standardized intelligence tests were developed for different age ranges and normal deviations were constructed as a means of identifying as subnormal those who fell below the range considered to be normal. Developmental tests were later designed to measure how closely individuals met “developmental” targets at each age. The discrepancy in measures on language, motor, and behavioral development assisted in defining various categories of what is

These various strands in the evolution of the law and science of disability converged with research and public policy in disability generally.

Changing Perspectives “norms” of development, but these norms remain just that—statistical constructions. Deviations from the norms do not signify “abnormal” development; they merely represent statistical deviations from a presumed norm. In this view, if children, youth, or adults do not proceed developmentally through a set of common functions, developmental stages, or critical developmental periods, then they are to be considered abnormal or to have deviations in physical, emotional, or skill development. This assumption, which has served to frame much of the practice in education, developmental psychology, and social science research, is increasingly being called into question (Amundson, 2000; Skrtic, 1991). It has been suggested that rather than being scientific and objective, the concept of functional normality reflects the beliefs, preferences, and cultural expectations of a majority of the members of society. As Amundson suggested, if what it means to be normal is indeed a product of the culture, then the yardsticks for measuring normalcy lack universal and scientific validity, and “disadvantages experienced by people assessed as abnormal derive not from biology, but from implicit social judgments about the acceptability of certain kinds of biological variation” (p. 33). The definition of normal becomes arbitrary, relative, and specific to the historical context in which it
at a population level, trends in development can be found across children and subgroups of children. Mackelprang and Salsgiver (1999) pointed to some of the intellectual foundations of a broader view of developmental theory that begin to address the cultural biases of predominant approaches based on normalcy. This work stresses that the focus in developmental theory must be shifted from measuring the gap between age and expected developmental achievements and measuring the standard deviations of that gap to focusing on the conditions that enable children and adults with disabilities to carry out “developmental tasks” that are culturally shared and defined.

40 model—has been advanced by those who find in the WHO and other definitions a “reductionist” tendency—reducing the disability to individual characteristics (Barnes, 1991; Oliver, 1996; Pothier & Devlin, 2006; Rioux, 1996; Rioux, Basser, & Jones, 2011). In a social model, disability arises from the discrimination and disadvantage individuals experience in relation to others because of their particular differences and characteristics. This shift in thinking finds a primary source in feminist and other identity theories of “difference” wherein the challenge is to recognize such differences as gender, race, sexual identity, and disability without assigning social or economic value on the basis of these differences (Carlson, 2010;

The social model, in today’s context, embraces human rights as a key method for society to assume its responsibility to ensure equal treatment and opportunities for all of its citizens (Rioux, Pinto, & Parekh, 2015). This reintroduces the notion of people with disabilities as legal entities described at the beginning of this chapter but stresses equality and citizenship rights in a way that brings into question the status that was first carved out for them under statutes such as De Prerogativa Regis and also questions the forms of institutional and community care that have taken away their basic rights to self-determination, citizenship, and freedom from discrimination in employment. Instead, the social model suggests a reconstruction of the legal, social, and economic status of people with disabilities, starting with recognition that, first and foremost, people are full, rights-bearing citizens.

Changing Perspectives people with disabilities themselves and those who are in personal relationships with them. Frazee (1997) has stressed the importance of creating a “culture” of disability wherein people’s differences, or impairments if they define them as such, can be named, given meaning, celebrated, and thereby transformed into a cultural and personal resource, even while people may experience limitations and
transformed into a cultural and personal resource, even while people may experience limitations and needs for support. The notions of a “social model of disability,” “personal experience of impairment,” and a “culture of disability” may not at first glance provide much hope of liberation to people with more profound intellectual and developmental disabilities, and indeed there has not been nearly as much attention in critical disability studies to the lived realities of this group. Many who are labeled with an intellectual or developmental disability have very challenging needs, are unable to communicate in ways that most others understand, sometimes act in ways that bring alarm to others, and sometimes demand attention from family and support workers. Those who advocate a social rather than biomedical perspective for understanding disability argue that it is most important to bring this perspective to individuals who are in such a situation. It is they whose voices about their own lives and life conditions are least likely to be heard but need to be for an understanding of disability (see Charlton, 1998, 2010; Couser, 1997, 2010). It is they who are most at risk of being devalued in society for their differences, who are defined as furthest from the norm, and who are perceived to be lacking a personal story or narrative that others value. As Eva Kittay—a philosopher who has a daughter with a profound intellectual disability—argued, the differences people with intellectual and developmental disabilities have in relation to others cannot be defined away as “social constructions.” These differences are real.

Closing the gap between exclusion and inclusion will require new roles and partnerships, including actors who for many years advocated for legal change working alongside service providers and people with disabilities themselves. For example, more individualized and person-centered planning, funding, and support services are essential if people with intellectual and developmental disabilities are going to be supported to maximize achievement, contribution, success, and belonging, each person along his or her unique developmental path. However, funding arrangements and service delivery systems in education, residential, employment, and community supports still largely foreclose this possibility because of their emphasis on congregate and often segregated approaches. Systems are beginning to change as individualized and person-directed approaches are tested and increasingly adopted (Kendrick, 2011).

In addition, recognition will be required that people with intellectual and developmental disabilities are not a homogenous group. They are located simultaneously in gendered, racialized, and culturally defined roles and relationships that also structure the limits and possibilities of reform at any point in time and place. For a social and human rights model of disability to take full account of the realities of people with intellectual and developmental disabilities, it must also attend to this more radical perspective on the multiple, sometimes conflictual, and always evolving nature of social identities. This perspective helps people to better understand the double and triple disadvantage some individuals face and also to identify opportunities to build common understanding and solidarity with groups who share forms of social and economic exclusion.

Changing Perspectives and the biomedical consequences and challenges they bring. A social model recognizes a biomedical view as one source of information for understanding disability. However, it changes the vision and purpose of intervention from “fixing,” “impairments,” and “abnormalities” to supporting people to exercise their human rights and thereby become full and val-
and “abnormalities” to supporting people to exercise their human rights and thereby become full and valued members of society. Although the implications of human rights obligations are still to be fully worked out, the vantage point they allow helps to reveal the inequalities in status between people with disabilities and the rest of the population and among people with disabilities themselves. They provide a legitimate ground on which to restructure the institutions and policies that have brought inequality in the past and to consider what entitlements people require in order to fully exercise their citizenship and equality rights. They also demand a restructuring of outmoded approaches to service delivery that still congregate and segregate people on the basis of intellectual and developmental disabilities. As understandings of these inequalities in status inch further and further into public consciousness, it can be hoped that genetic, behavioral, communicational, and intellectual differences will be seen for what they are—signs of diversity, horizons of human possibility, and a
place to nurture support, belonging, and reciprocity.
SUMMARY Intellectual and developmental disability is usually thought of as an intellectual deficit or developmental delay arising from a genetic “deficiency” or other condition, which becomes visible in the early years of life. Stepping back from this assumed definition, it can be seen that disability is, first and foremost, a term applied by some people to others. The term is rooted in legal distinctions that go back hundreds of years to a time when the state first became concerned with distinguishing those considered to have the requisite “reason” to manage property and
