Figure 2.

Frequency distribution (in %) of the schizophrenia (blackened bars) and control (unblackened bars) groups, according to their standardized scores on the disease-related canonical neuropsychological variate. The canonical variate represents the linear combination of neuropsychological scores that best discriminates among diagnostic groups; the measures contributing uniquely to the discrimination are (in order of magnitude) verbal episodic memory, visual episodic memory, motor speed, spatial working memory, divided attention, and choice reaction time. For statistical information, see table 3.
