Fig. 3. Effect of the number of items on memory in sequential and in simultaneous presentation.

Average precision (across all items) decreased with increasing number of items presented in a sequence (black line), or simultaneously (red line). Note that the last object in a sequence (blue dash-dotted line) was remembered with similar precision to an item in an array of the same number of simultaneously presented objects. There was no significant difference for one item in “sequential” compared to “simultaneous” conditions. Error bars are SEM.
