I maybe expecting to perceive less from the left side of others faces (right visual field) so that is what I perceive. But then it would seem that there would not be a documented condition of pseudo neglect 

I still have to make a deliberate attempt to see the left side of faces during conversation but it has become more habitual. Watching interviews and such online I feel I get more micro expressions displayed on the right half of others (left visual field) face than the left. I think I expect to see the right half of others (left visual field)expressing the emotions I need to see to understand them.

The the thing is on purpose though I often do it accidently
