It’s not too hard to see why working memory could be so important. Working memory boils down to ‘how much stuff you can think about at the same time’. I magine a poor programmer who has suffered brain damage and has only enough working memory for 1 definition at a time. How could he write anything? To write a correct program, he needs to know simultaneously 2 things - what a variable, say, contains, and what is valid input for a program. But unfortunately, our programmer can know that the variable foo contains a string with the input, or he can know that the function processInput uses a string, but he can’t remember these 2 things simultaneously! He will deadlock forever, unsure either what to do with this foo, or unsure what exactly processInput was supposed to work on. .... "
