Have you ever walked into a room and immediately felt comfortable or, conversely, felt uneasy for no apparent reason? This instinctive response is part of what's called "neuroception." Neuroception is a term coined by Dr. Stephen Porges that describes how our brain and nervous system unconsciously scan our environment to assess whether we are safe, in danger, or facing a life-threatening situation. This process is crucial because it helps us decide how to react, even before we're fully aware of what's happening.
For people with autism, neuroception can work a bit differently. Many autistic individuals have heightened sensitivity to sensory experiences, such as bright lights, loud sounds, or crowded spaces. Because of this heightened sensitivity, their nervous system might misinterpret these benign environments as dangerous or threatening, leading to feelings of anxiety or discomfort. This is why you might notice some autistic people avoiding certain places or situations—they are simply responding to what their body perceives as a threat. This reaction is sometimes linked to a phenomenon called "hostile attribution bias," where individuals are more likely to interpret ambiguous situations as having hostile intent.
