A magnet metaphor for problem-solving. In novices, many cognitive resources are highly attracted to problems. Such knowledge is often poorly organized and sensitized, leading to working memory overload. In experts, much naive knowledge has been appropriately sensitized to context (demagnetized) so that it is not attracted to problems but may be used in other contexts.
