Final answer:
The duration of the auditory sensory register, a part of sensory memory, is approximately 4 to 5 seconds. This temporary storage allows for the processing and interpretation of auditory stimuli before it either fades or moves to short-term memory.
Step-by-step explanation:
The duration of the auditory sensory register, which is a part of sensory memory, is approximately A) 4 to 5 seconds. Sensory memory is the initial, temporary storage for sensory information, and this includes the auditory information that we hear. For example, after hearing a sound, the sensation of that sound persists for a brief moment even after the sound has stopped. This brief persistence allows our brain a short amount of time to process and interpret auditory stimuli before it either fades away or is passed onto short-term memory. According to the Atkinson-Shiffrin model of memory, sensory memory storage lasts up to a couple of seconds. Auditory sensory memory, also known as echoic memory, can last slightly longer, thus the approximately 4 to 5 seconds duration.
