Researchers presented Elizabeth's right eye with a 10,000-dot pattern for 1 minute.A few seconds later, they presented a slightly different 10,000-dot pattern to her left eye, and asked her to superimpose the two patterns to perceive a three-dimensional object.Elizabeth's ability to do this successfully indicated
A)her iconic memory was abnormally persistent
B)her long-term memory was abnormally three-dimensional
C)her eidetic imagery was typical of most people
D)echoic memory was abnormally transient

Question

Quizplus · Accepted Answer

Elizabeth's ability to superimpose the two patterns and perceive a three-dimensional object after a few seconds suggests that her iconic memory was unusually persistent. Iconic memory is the brief visual sensory memory that stores a detailed image of a visual stimulus for a very short period of time. This ability to retain a detailed image of the pattern in her memory for a few seconds implies her iconic memory had an abnormally long duration.
