Abstract: Improving problem solving requires understanding what difficulties people have when they approach novel problems. Some of the known difficulties include identifying and understanding the operators (Kotovsky & Simon, 1990) or having implicit but wrong constraints on move selection (Richard, Poitrenaud, & Tijus, 1993), memory load imposed by the task or external circumstances (Kotovsky, Hayes, & Simon, 1985), whether the rules agree with real-world knowledge (Griggs & Cox, 1983; Kotovsky & Simon, 1990), difficulties in planning ahead (Atwood, Masson, & Polson, 1980; Atwood & Polson, 1976; Delaney, Ericsson, & Knowles, 2004), failures to sufficiently reflect on move selection (Davies, 2000), and heuristic biases that may lead problem solvers to select the wrong move at any given time (e.g., Atwood et al., 1980; Atwood & Polson, 1976).
