Q. What role does emotion have in the life of someone with autism? I just find the whole disorder of autism hard to understand because I'm a really emotional person. I'm especially interested in how people with mild autism or Asperger's can function fine but then when it comes to feeling empathy they have such trouble. I guess my question is how such people experience emotion--are these people actually unable to care about others? My intention is not to sound ignorant, I'm genuinely curious.
A. I have Asperger's syndrome. People with autism spectrum disorders do have feelings and emotions. Many of us lack empathy, but that doesn't mean we don't care about others. For example when someone is really excited about something nice in their life, we may not get excited too. It's not that we don't care, it's just that we don't experience other people's emotions with them. I can be happy for them while not really understanding or feeling the excitement involved. We don't know exactly what the other person feels like and therefore we can hardly share in feeling those emotions with them. We also don't always express our emotions or we don't do it the same way as others.
