In the partial report method of Sperling's study of sensory memory, the participants were to report
A) one of three lines of letters as indicated by the sound of a tone immediately presented after the letters had disappeared.
B) only one or two of the letters in the cued line.
C) the first letter of each line only.
D) the middle letter of each line.
Answer: A
Rationale: In the partial report condition devised by Sperling, researchers flash a set of letters on the screen, but the display is followed immediately by a tone that is randomly chosen to be low, medium, or high. After hearing the tone, participants are to report the corresponding line—bottom, middle, or top. Under these conditions, participants still report only three or four of the letters, but they can report them from any randomly selected line.
