THEORETICAL ASPECTS OF INTELLECTUAL DISABILITY - DEFINITION, CLASSIFICATION

Abstract

The onset of intellectual disability is marked by impairment of all parts that contribute to an individual's intelligence, such as the functions of socialization, knowledge, speech, and motor function. Intellectual disability is also defined, involving significant limitations in both intellectual functioning and adaptive behavior, which cover many daily social, motor, and practical skills. The most commonly accepted definition of intellectual disability is that provided by AAIDD: “Intellectual disability is a disability characterized by significant reductions in both mental functioning and adaptive behavior, covering many daily social and practical skills. This disability originates before the age of 18.”
