Without sensory memory, which of the following would be likely?
A) Moving objects would appear to be a series of isolated still images.
B) We would have trouble remembering the smell of our grandmother's old house.
C) We could not be conditioned to fear a tone.
D) We could not perform mental arithmetic.
Answer: A
Rationale: If not for iconic sensory memory, our visual experience would probably be similar to that of looking around a room with a strobe light flashing—everything would appear to be a series of isolated and still images. Instead, iconic sensory memory holds images long enough to provide smooth, continuous perceptions. Sensory memory lasts for too short a duration to play a prominent role in the other listed abilities.
