Some models of problem solving involve identifying a [[goal]] and then a sequence of subgoals towards achieving this goal. Andersson, who introduced the [[ACT-R]] model of cognition, modelled this collection of goals and subgoals as a [[Stack (abstract data type)|goal stack]] in which the mind contains a stack of goals and subgoals to be completed, and a single task being carried out at any time.<ref name=":1">{{Cite book |last=Robertson |first=S.

Knowledge of how to solve one problem can be applied to another problem, in a process known as [[Knowledge transfer|transfer]].{{r|:1|page=56}}
