Level 4: Even Tougher Thoughts
Let’s step up the cognitive load again. Imagine if now, the numbered thoughts came not as numbers, but as simple arithmetic problems that must be solved. Instead of a thought labelled ‘3’ it arrives as ‘2+1’ or ‘7-4’. These are simple enough but still harder than recognising single digit. This is going to use even more energy from your foreground conscious mind, and your working memory, to solve before you even try to send the thought to its correct destination (based on the result).
