Vocabulary performance of short-term and long-term schizophrenics.

"The following three measures of vocabulary performance varying in sensitivity were obtained from groups of short-term schizophrenics, long-term schizophrenics, and normals equated for art and education: gesticulation (nonverbal), conventional vocabulary achievement, and level of verbal communication. No differences were found between the short-term schizophrenics and the normals of any of the measures. The long-term schizophrenics were significantly lower than normals and short-term schizophrenics on all of the measures. The decrement on gesticulation for the long-term schizophrenics was significantly less than that for the other measures." (PsycINFO Database Record (c) 2010 APA, all rights reserved)
