Maybe the ten hours of studying have caused extreme pressure to my brain, or maybe having three exams in one day impedes on my ability to think critically, but I've stared at this sentence in my Developmental Psych book for an hour now, and I must be missing something:

In an observational study of blind children enrolled in preschools with sighted agemates, the blind children were less likely to initiate contact with peers and teachers.

I have no idea how this could be true. Oh, perhaps because the children can't see their peers and teachers!!!
