Interestingly, there is an inverse relationship between working memory and the amount
of sensory input you’re processing at any given time. People with high-functioning
working memories are better able to screen out what’s going on around them. Your
prefrontal cortex determines what you should pay attention to. If you can tune out all
the sensory stimuli around you, and instead focus your attention on the one thing in
your working memory, you’ll be able to remember it.
