What is parallel processing?
When you are able to consider multiples aspects of something at once. When you look at an apple, you don’t identify it as red followed by round followed by shiny. You would identify all of those things at once.
In psychology, parallel processing is the ability of the brain to simultaneously process incoming stimuli of differing quality. Parallel processing is a part of vision in that the brain divides what it sees into four components: color, motion, shape, and depth.
