>It is a biological reality and is built through any experience Those two things don't comport with one another. You seem confused. Working memory is indeed a biological reality. You don't "build" working memory. Each Individual has their own fixed capacity for short-term working memory rooted in biology. According to "The Neuroscience of Intelligence", on the weight of evidence higher intelligence comes down to larger brain volume combined with shorter pathways within and between brain networks. It's not hard to imagine the effect those two things have on working memory. What I was saying is that this innate capacity for working memory is the basis for a positive feedback loop where the cognitively rich get cognitively richer. One's working memory isn't changed by learning things, rather the more things one has learned, the less work one has to do to learn additional / related things.
