I have come to think as willpower depletion as: "RAM is full. To start new processes that take up cognitive resources, please terminate some of those which are running at the moment before new threads can be started."
It well explains why some people experience willpower depletion and other don't. Those that experience don't release the mental resources but their brain continues analysing the situation to learn from it.
If so, I would be interested in whether this affect has been incorporated into any dieting strategies.
How would you do that? Don't memorize long numbers right before choosing what to eat, doesn't seem very practical advice.
It's encourages grocery lists instead of keeping that information in your head, but that's best practice anyway for commitment reasons if you want to focus on buying healthy food.
How would you do that?
Cognitive load is a fairly general phenomenon, not limited to memorizing long numbers. You can experience cognitive load simply by living a busy life where you are constantly thinking about other things, and not able to be "present".
I was recently reading a blog here, that referenced a paper done in 1999 by Baba Shiv and Alex Fedorikhin (Heart and Mind in Conflict: The Interplay of Affect and Cognition in Consumer Decision Making). In it, volunteers are asked to memorise short or long numbers and then asked to chose a snack as a reward. The snack is either fruit or cake. The actual paper seems to go into a lot of details that are irrelevent to the blog post, but doesn't actually seem to contradict anything the blog post says. The result seems to be that those with a higher cognitive load were far more likely to chose the cake than those who weren't.
I was wondering if anyone has read any further on this line of research? The actual experiment seems to imply that the connection between cognitive load and willpower may be an acute effect - possibly not lasting very long. The choice of snack is made seconds after memorising a number and while actively trying to keep the number in memory for short term recall a few minutes later. There doesn't seem to be anything about the effect on willpower minutes or hours later.
Does anyone know if the effect lasts longer than a few seconds? If so, I would be interested in whether this affect has been incorporated into any dieting strategies.
