0 a term used to refer to the brain condition of someone who does not show any of the characteristics associated with autism:
People with allism tend to engage actively in group activities and do not tend to develop their own individualized interests in the same ways that autistic people often can.
The word "allism" is not synonymous with "neurotypical" —allistic people are by definition not autistic, but can be neurodivergent in other ways (e.g. dyslexia).
