Fig. 8. Comparing simultaneous and sequential presentation when all items are displayed at different locations.

When each object in a sequence was presented at a different spatial location, memory across all items in the sequence (black line) was, on average, less precise than when the same number of objects were presented simultaneously (red line). Precision for the last item in a sequence (blue dash-dotted line) is no different than for an item in an array of the same set size. Note that, for both simultaneous and sequential presentation, precision values are similar to those in Fig. 3. Error bars are SEM.
