Well I think daydreaming (non-fear related) plus a mix of fear in social situations could potentially cause blocks more than just fear alone. Because in both situations, the PWS is disengaged from the social situation, which isn’t helpful for our speaking process in its entirety. It’s kinda like it may be difficult for a person to be romantic, dance, or be or silly if they are deep in thought about something they can’t relate or that doesn’t feed energy into these things.
