Neurocognitive functioning will be assessed at baseline (study entry), after cognitive training (6 months), and at 12 month follow-up, using the MATRICS Consensus Cognitive Battery (MCCB). The investigators will assess the following six constructs identified by MATRICS as separable, fundamental dimensions of cognitive impairment in schizophrenia, with a likely sensitivity to intervention \[26\]: 1) Speed of Processing, 2) Attention/Vigilance, 3) Working Memory, 4) Verbal Learning and Memory, 5) Visual Learning and Memory, and 6) Reasoning and Problem Solving (executive functioning). The investigators will also administer the delayed memory trials of HVLT and BVMT, Trails B, and D-KEFS Color-Word Interference Test \[27\], and will make one modification to the MCCB in utilizing BACS Tower of London \[28\] in place of NAB Mazes.
