How do verbal and nonverbal communication difficulties affect people with autism? 

Author: Beatrice Holloway, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

Understanding verbal and nonverbal communication in autism is crucial to recognising how differently people may express themselves. These challenges can impact everything from everyday conversations to forming deeper relationships. For many, verbal and nonverbal communication in autism involves a unique set of hurdles that can often go unnoticed by others.

Verbal differences might include delays in spoken language, limited vocabulary, or trouble with tone and volume. On the nonverbal side, interpreting or using body language like facial expressions, gestures, or eye contact can be confusing or even uncomfortable. Combined, these can make social interaction feel unpredictable or overwhelming. But these challenges don’t mean a lack of understanding or intelligence, they often reflect a different way of connecting with the world.

Signs of Communication Differences

These common signs offer insight into how communication may look and feel for someone on the spectrum:

Difficulty Reading Nonverbal Cues

A person may not recognise when someone is joking, annoyed, or expecting a response based on their facial expression or posture.

Limited or Literal Speech

Speech may be direct and concise, sometimes missing social subtleties like sarcasm, filler words, or unwritten conversational rules.

Unusual Use of Gesture or Eye Contact

An individual might avoid eye contact or not use gestures to emphasise points, which can be misread as disinterest or rudeness.

These differences deserve understanding, not correction.
