Which category is defined by significant limitations in intellectual functioning and adaptive behavior?

• A. Autism Spectrum Disorder
• B. Speech or Language Impairments
• C. Hearing Impairments
• D. Intellectual Disabilities

Answer: (D)

Significant limitations in intellectual functioning and adaptive behavior describe Intellectual Disabilities. Intellectual functioning covers reasoning, problem solving, learning, and overall thinking abilities. Adaptive behavior refers to the practical and social skills needed for daily life, including communication, daily living activities, social interaction, and independently managing tasks like safety, money, and time. For this category, these limitations must appear during the developmental period, typically before age 18, and they affect performance across multiple settings such as home and school. This framework helps distinguish Intellectual Disabilities from other categories that may involve one area of difficulty but not the combined, long‑lasting impact on thinking and everyday functioning. For example, Autism Spectrum Disorder centers on social communication challenges and restricted behaviors, while hearing impairments affect sensory input and speech or language impairments focus on communication without necessarily involving broad adaptive limitations.
