Comedy star Chris Rock has revealed he was recently diagnosed with nonverbal learning disorder, which causes difficulty in interpreting nonverbal cues. While persons with this neurological condition are often highly verbal and intelligent, they might be unable to read subtle intuitive cues such as facial expressions and body language. The comedian said that he can often take things too literally and suffer from all-or-nothing thinking, a common symptom of his condition. "Any time someone would respond to me in a negative way, I'd think, 'Whatever, they're responding to something that has to do with who they think I am,' " Rock said. "Now, I'm realizing it was me. A lot of it was me."
