Fig. 1.

Procedure and results from the study of Leonard et al. (2013). (A) Example of a single trial. Participants were instructed to remember the colors of the target shapes in the first display (either the circles or the rectangles) and report whether a color of target shape changed between the two displays. Shown here is a ‘no change’ trial at memory load 3 when the circles were the to-be-remembered targets. (B) Average CDA amplitude at each memory load for healthy control subjects (HCS) and people with schizophrenia (PSZ), averaged across the time period of interest (i.e., 400–1000 ms after the onset of the first array). Error bars indicate ± 1 S.E. * = p < .05, ** = p< .01. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
