"We identified that autistic people had a specific difficulty recognizing anger, which we are starting to think may relate to differences in the way autistic and non-autistic people produce these expressions," said Connor Keating, a researcher in the University of Birmingham's School of Psychology and Centre for Human Brain Health. "If this is true, it may not be accurate to talk about autistic people as having an 'impairment' or 'deficit' in recognizing emotion — it's more that autistic and non-autistic faces may be speaking a different language when it comes to conveying emotion." The researchers also discovered that people with a related condition, alexithymia, tend to interpret all types of expressions as more intensely emotional than they actually are.
