Facial Recognition / Prosopagnosia

Hello all,

I seem to have a problem with facial recognition. For example, I might see someone in the street or in a shop who looks like someone I know. So I walk up to them and say hello (overriding my inclination to walk away and not engage with them at all), and then I realise that it isn't the person I thought it was. It's a complete stranger.

On the flipside, I may see someone that I know, the actual real person, but I don't register their face, particularly if I'm seeing them out of context, and I completely blank them.

Has anyone else experienced this? I know that prosopagnosia / face blindness is not uncommon among the autistic population. I have heard other autistic people mention similar stories to the second example - not recognising people you know - but not necessarily the first example, seeing someone who looks 'a bit' like someone you know, and then you either spend a long time wondering if it's them, perhaps watching them from across the street, or you actually go up to them and then discover, when they look at you blankly or speak in a different voice, that it's a total stranger.

This has happened to me a number of times. Normally it's a mildly amusing experience, if a little discombobulating.

Best wishes,

Matt
