Final answer:
Echoic memory is the term for the brief sensory memory of auditory stimuli, which can be recalled for about 3-4 seconds when attention is elsewhere, facilitated by the temporal lobe.
Step-by-step explanation:
The term for the momentary sensory memory of auditory stimuli is echoic memory. Echoic memory is part of sensory memory storage, which also includes visual memory (iconic memory). If attention is elsewhere, sounds and words can typically still be recalled for about 3-4 seconds after presentation. This duration allows for the brief retention of auditory information, even when one's focus is not primarily on those auditory signals. This can be observed when we can recall the last few words spoken by someone, even if we were not actively listening. The temporal lobe plays a significant role in processing auditory information and contributing to the formation of long-term memories for these stimuli.
