Cognitive Load and Working Memory

The amount of information entering our consciousness at any instant is referred to as our cognitive load. When our cognitive load exceeds the capacity of our working memory, our intellectual abilities take a hit. Information zips into and out of our mind so quickly that we never gain a good mental grip on it. (Which is why you can’t remember what you went to the kitchen to do.) The information vanishes before we’ve had an opportunity to transfer it into our long-term memory and weave it into knowledge. We remember less, and our ability to think critically and conceptually weakens. An overloaded working memory also tends to increase our distractedness. After all, as the neuroscientist Torkel Klingberg has pointed out, “We have to remember what it is we are to concentrate on.” Lose your hold on that and you’ll find “distractions more distracting.”
