Both echoic and iconic memories
are part of the sensory memory. Sensory memory refers to an individual’s
ability to retain impression of sensory information for a brief time after the
original stimulus has ceased. It is an automatic response that is considered to

for a duration of 100 milliseconds; while echoic memories are inputs to the
auditory system that can only hold information for about 3-4 seconds.</span>
