Positive relationship between working memory drift and distractibility. Linear regression was used to calculate the slope of working memory drift over time for each subject The resulting regression slopes (β values) for each subject were correlated with angular displacement in the distal distractor condition. The black line shows the positive correlation between the two—the more WM drift with increasing delay, the greater the distractor bias—suggesting possible shared mechanisms (Fig. 2E) (Murray et al., 2014). Here we collapsed the analysis across both SCZ and HCS to maximize power given that spatial WM is a continuous measure and a construct highly consistent with a ‘dimensional’ perturbation (Cuthbert and Insel, 2013).
