=== Visual bar cue ===
A small variation in Sperling's partial report procedure which yielded similar results was the use of a visual bar marker instead of an auditory tone as the retrieval cue. In this modification, participants were presented with a visual display of 2 rows of 8 letters for 50 ms.  The probe was a visual bar placed above or below a letter's position simultaneously with array offset.  Participants had an average accuracy of 65% when asked to recall the designated letter.<ref name ="Averbach"/>
