the superiority of visual memory over auditory memory

[orwaldtan]

Dear all,
I am wondering about a concept related to human memory. I am doing an investigation regarding the superiority of
visual memory over auditory memory.What could be a proper explanation in terms of BIOLOGICAL PRINCIPLES? In this case, maybe neurophysiology mechanisms, like maybe visual cortex from where visual memory is retrieved is activated more?.
Is there any useful website links(journals) or book(s) regarding this?

Thank you for your help and time.

Any recommendation is greatly appreciated.

What makes you think it IS superior? Some people's memory is primarily visual, others auditory, some may focus on even other senses. I'm not sure what "superior" actually means - depending on that, olfactory memory might be superior...
