Assertion: Adaptive behaviour refers to a person’s capacity to be dependent and deal effectively with one’s environment.

Reasoning: Deficits in adaptive behaviour is one of the three feature which is required to be present in a person to regard him/her as intellectually disabled.

The Assertion is false, but the Reasoning is true.

The American Association on Mental Deficiency (AAMD) views intellectual disability as “significantly sub-average general intellectual functioning existing concurrently with deficits in adaptive behaviour and manifested during the developmental period”. This definition points to three basic features. First, in order to be judged as intellectually disabled, a person must show significantly sub-average intellectual functioning. Persons having IQs below 70 are judged to have sub-average intelligence. The second relates to deficits in adaptive behaviour. Adaptive behaviour refers to a person’s capacity to be independent and deal effectively with one’s environment. The third feature is that the deficits must be observed during the developmental period, that is between 0 and 18 years of age.
