What it studies
Developmental disabilities research studies conditions that begin in the developmental period and affect everyday functioning. AAIDD describes intellectual disability as one of several conditions known collectively as developmental disabilities, defined by significant limitations in both intellectual functioning and adaptive behavior, with onset before age 22.
History and people
AAIDD says it was founded in 1876 and calls itself the oldest and largest interdisciplinary membership organization in the field. The Association of University Centers on Disabilities says Congress established the Intellectual and Developmental Disabilities Research Centers in 1963. The sources opened here do not document the history of psychological research on developmental disabilities specifically, or the association's earlier names.
People and documented roles
The sources checked for this profile name no individual contributors.
The sources opened are organizational pages and name no individual contributors. They do not document early researchers, women scholars, or contributors outside the United States, so no people are listed rather than guessing.
Dated milestones
- 1876Society or organization formed. Year.AAIDD says it was founded in 1876; its earlier names are not covered by the sources opened (a society milestone, not the start of the field). [2]
- 1963Institution built. Year.Congress establishes the Intellectual and Developmental Disabilities Research Centers, according to AUCD; NICHD materials say only 'since their inception in the 1960s'. [3]
Methods
AAIDD's definition pairs intellectual functioning with adaptive behavior, which it describes as conceptual, social and practical skills learned and performed in everyday life. The National Institute of Child Health and Human Development describes center work using genomics and other omics, neuroimaging, model organism and cellular models, and complex cognitive and behavioral phenotyping intended to encourage clinical translational research.
Training and applications
In the United States, the Association of University Centers on Disabilities lists a network of 15 research centers funded through core grants from the National Institute of Child Health and Human Development. AAIDD describes its work as promoting progressive policies, sound research, effective practices and universal human rights. The sources opened here do not describe training routes or credentials, and this guide states none.
Boundaries and limits
Developmental disabilities is a broad category, and AAIDD stresses that additional factors must be taken into account when assessing intellectual disability, so a category does not describe an individual's strengths and needs. The sources opened here come from a disability association and from research centers focused on biology and behavior, so the specific role of psychology is not established. The institutions described are United States organizations.
Evidence behind the claims
AAIDD defines intellectual disability by significant limitations in both intellectual functioning and adaptive behavior, with onset before age 22.
AAIDD describes adaptive behavior as the conceptual, social and practical skills that are learned and performed by people in their everyday lives.
AAIDD says intellectual disability is one of several conditions known collectively as developmental disabilities, and stresses that additional factors must be taken into account when assessing intellectual disability.
AAIDD says it was founded in 1876.
AAIDD calls itself the oldest and largest interdisciplinary membership organization in the field and says it promotes progressive policies, sound research, effective practices and universal human rights for people with intellectual and developmental disabilities.
AUCD says Congress established the Intellectual and Developmental Disabilities Research Centers in 1963 as centers of excellence for research on intellectual and developmental disabilities.
AUCD lists 15 IDDRCs in its network, funded by the National Institute of Child Health and Human Development through P50 core grants.
NICHD council materials describe IDDRC research resources including genomic and other omics analyses, neuroimaging, model organism and cellular models, and complex cognitive and behavioral phenotyping intended to encourage clinical translational research.
