Were sensory memories to last longer than normal,
a. we would need more working memory
b. our senses would not work together
c. we would become overloaded by the amount of incoming information
d. it would ultimately destroy cortical neurons
e. sensory memory would be able to hold more information

C. we would become overloaded by the amount of incoming information

Explanation:

Sensory memory is the retention of information perceived by our 5 senses before it is processed into our short-term memory. It is responsible for providing the visual, auditory, tactile, olfactory and taste stimuli for our memory.

In our brain it represents areas and nerve endings responsible for the sensory organs and has enormous speed. But on the other hand her retention is very short-lived, only until her electrical impulses reach short-term memory, which may later discard them or not.

If sensory memory lasted longer, our brain would not have the ability to exclude unimportant information and we would be overwhelmed with the amount of information we received.
