I am not diagnosed with auditory processing disorder (never been tested so make of this what you will), but I have trouble looking someone in the eye while they are talking because then I lose track of what they are saying. I glance at them so they know that I am listening or paying attention, but if I look at them too long, my mind wanders and I sometimes find myself watching their face move or watching their eyes instead of really hearing what they are saying or thinking about how to show that I am listening. In high school and college, my eyes would hurt or burn because it was like I was going to cry. And back then it was also because I didn't know how to do it with people I wasn't very, very familiar with or very comfortable with. I didn't know how to be comfortable with it. And more often than not it was like I got an over-powering load of information from it. I only recently learned that other people can't tell if you aren't looking them in the eye directly, that they can't tell if you are looking at their nose or their eyebrow or a spot on their forehead. I used to have problems even looking at someone's face sometimes, especially if I was nervous or really, really liked them. People have always mentioned how little I look at them, but I always thought they just weren't paying attention to me enough because I thought I was looking at them enough.
The not being able to look at someone much and hear what they are saying is way worse with people that are new or rare with me, people who talk fast or who talk loudly or quietly, in loud, stimulating, new/newish, busy environments, and as the conversation goes on with even a familiar person in a very familiar or quiet place, or if the discussion is not on a particular, factual topic. If it is someone I am one-on-one with and am around a lot I don't think so much about looking at them to let them know I am listening because they know how I am. I also find that I picture what people say to me to follow what they are saying, either in pictures and/or in text. I also mis-hear things, like I misunderstand because I hear a syllable/sound/word that wasn't there or don't hear a syllable/sound/word that was there; sometimes this can change the entire meaning of what was said.
So, for me, it is more to do with sensory stuff nowadays, like an auditory processing issue. I am finding that a lot of my problems are made more obvious and harder to cope with under sensory strain or distraction. And I have difficulty splitting my senses and attention. I can do it sometimes, but not in the "everyday" sense.
