“I may feel it, but my face and voice don’t show it.”
Flat Affect may be caused by different things:
- lack of mirroring, see ASPD
- lack of prosody
- lack of emotion
My Experience
Since I have no Social Salience I receive no signal and there is nothing to mirror. In fact I probably give off strange vibes.
For whatever reason I also have low prosody – I tend to talk in a bit of a monotone and at a constant rate (sometimes fast, sometimes slow, usually the wrong speed). If I pay attention I think I can affect this, e.g. if I am telling a joke (but my jokes often fall flat, so my mileage may vary!).
I have emotions, I am just not expressing them in a way that NT receivers would pick them up.
