Is the type of auditory memory comparing two sounds over time called echoic memory or if not, what type of memory is that? I read that echoic memory lasts 2-5 seconds. But I'm not sure if that is the same thing as comparing adjacent sounds in time. Can anyone clarify this?
Using http://en.wikipedia.org/wiki/Echoic_memory as my guide, I would say that echoic memory refers to something that has less detail and longer duration than the kind of memory involved with hearing subtle differences near the threshold of hearing.
Fun fact: the visual sensory store lasts only about 1 second.
