No, I don't catch yawns. My mother pointed it out to me. I can watch all the yawning videos on YouTube and I get nothing (animals and people).
It's an empathy thing -- social empathy based on nonverbal cues and the automatic recognition of such. A good portion of people with an ASD don't "catch" them. There's studies on it.
AS here.
For example:
Quote:
Different from spontaneous yawning, contagious yawning seems to be impaired in autistic children. Indeed, typically developing children yawned more watching or hearing others yawn than both HFA children (only one of them yawned observing others yawn) and LFA children (none of them yawned either observing or hearing others yawn). This result does not depend either on the differences of spontaneous yawning among the three groups or the differences of spontaneous yawn distribution during the daytime.
