The model proposed by Atkinson and Shriffin that describes memory as a mechanism that involves processing information through a series of stages including short term and long term memory
What is sensory memory

What does persistence of vision refer to
The continued perception of light for a fraction of a second after the original light stimulus had been extinguished
What is the “whole report method”?
