dyssemia
n. difficulty in receiving or sending nonverbal cues. More specifically, people with dyssemia have trouble interpreting (decoding) or producing (encoding) interpersonal information in the form of facial, postural, gestural, and paralinguistic expressions. For example, a person with dyssemia might fail to recognize the wide eyes of someone who is fearful. This nonverbal processing deficit is associated with a variety of social difficulties, including problems forming and maintaining friendships, conflict with others, and isolation or rejection. Innate or acquired damage to the amygdala or other limbic system structures is the most common contributing factor. See also Emory Dyssemia Index.
