Autism is described as:

• A. A disorder that appears in childhood and is marked by deficient communication, social interaction, and understanding of others' states of mind.
• B. Usually occurs before age 3.
• C. A hearing impairment that affects language processing.
• D. An unrelated learning disability.

Answer: (A)

Autism is a neurodevelopmental condition that typically appears in childhood. Its defining features are persistent difficulties in communication and social interaction, along with challenges in understanding others’ mental states (often described as theory of mind deficits). This combination distinguishes autism from conditions like hearing impairments, which affect language processing due to sensory loss, or unrelated learning disabilities. So, describing autism as a disorder that emerges in childhood with deficits in communication, social interaction, and understanding others’ minds best captures its core pattern.
