Influence of delay period on memory precision and response time. (A) Group mean (± SEM) of the standard deviation (precision⁻¹) for subjects' matching responses in a task testing free report from memory of stimulus orientation, as a function of the number of items presented and the delay before the cue to respond. (B) Group median response time for the same conditions, reflecting the combined duration of memory recall and rotation of the dial to the remembered orientation (± within-subject SEM, calculated after excluding variability associated with between-subject differences, as described in Cousineau, 2005).
