Interesting. DD seems to "over-process" information. I have had a few different people tell me she notices details that no one else would ever comment on (like how many spaces the line on a quarter note takes up, or specific patterns in musical pieces), but she is incredibly slow with seeing things that should be obvious, like 2+3=5. One psych told me he thinks DD has slow processing speed because she's not filtering things out and takes in way too much sensory information (in terms of auditory/visual perception at least). I always figured it's related to her ADHD.
