a) Proportion correct on No Distractor trials (red) versus Distractor trials (blue) for controls (CTRL), schizophrenia probands (PSZ), and relatives of PSZ (REL); CTRL and REL showed a markedly greater advantage in performance on Distractor trials than PSZ. b) Response reaction times to Probes at Previous Target positions, Previous Distractor positions, and Elsewhere for CTRL, PSZ and REL; CTRL and REL showed decreased reaction times to probes in Previous Distractor positions as well as Previous Target positions, whereas PSZ showed decreased reaction times only to probes in the position of a Previous Target stimulus. *p < .05, **p < .01, ***p < .001.
