Number of items stored in WM (K ± standard error of the mean) from experiment 1. (A) The mean number of items stored for each condition, (B) the filtering cost. 3:0 = 3 targets, 0 distractors; 3:2 = 3 targets, 2 distractors; 5:0 = 5 targets, 0 distractors. K was lower in PSZ compared with HCS for all 3 trial types (P < .001) and did not decline significantly between the 3:0 and the 3:2 conditions for either group (P’s > .13). PSZ and HCS did not differ in K DIFF (P = .12) or K RATIO (P = .21). HCS = healthy control subject; PSZ = people with schizophrenia; WM = working memory.
