Mean localization error increases with more objects to remember.

Abstract

<p>(A) Experiment 1: One to 5 <i>o</i>bjects were simultaneously presented at random locations on the screen for 1–5 seconds (1 second per item displayed). Following a delay of 1 second, the objects reappeared in novel random locations and participants were required to “drag” them using the touch screen to their remembered locations. The original locations of objects are shown here in light grey only for illustrative purposes; participants did not receive any feedback as to their errors. (B) Illustration of the dependant variable: distance between the reported locations and their matching original locations. (C) Mean localization error relative to the number of objects presented in the trial. Error bars denote SEM across participants.</p
