Sperling's partial report procedure involved briefly flashing a matrix of 12 letters to participants and then immediately sounding a tone to cue them to report a specific row of letters. The participants were able to accurately report about 3-4 letters from the cued row, indicating that they had perceived and encoded most of the letters in the display. By extrapolating from the number of letters typically reported and the total number of letters in the display, Sperling estimated that participants initially saw and encoded about 82% of the letters before the image faded from sensory memory. Therefore, the best choice is D) 82.
