Precision versus capacity of working memory in schizophrenic and healthy individuals

In this study, participants viewed a briefly-presented array of colored squares. After a delay, the location of one square was cued and participants clicked on a color wheel to indicate the color they recalled at that location. Responses were assumed to fall into two categories: (a) trials where the cued color was stored, so responses were distributed (with some variability) around the correct color, and (b) those where the cued color was not stored, so responses were scattered randomly around the color wheel.
