Note: The proportions of hits and correct rejections from STM that were correctly endorsed as “old” at LTM (i.e., LTM hits) are shown. The proportions of STM hits endorsed as “old” at LTM for which exact location was correct are shown. Standard deviations are in parentheses. Reaction times are in milliseconds and assessed from the response prompt. Pr is the corrected recognition measure (hit-false alarms) as defined in Snodgrass and Corwin (1988).
