    "title": "When High WMC Promotes Mental Set: A Model of the Water Jar Task",
    "subtitle": null,
    "abstract": "Differences in working memory capacity (WM C) relate to\nperformance on a variety of problem solving tasks. High WM C is\nbeneficial for solving analytical problems, but can hinder\nperformance on insight problems (DeCaro & Beilock, 2010). One\nsuggested reason for WM C-related differences in problem solving\nperformance is differences in strategy selection, in which high\nWM C individuals tend toward complex algorithmic strategies\n(Engle, 2002). High WM C might increase the likelihood of non-\noptimal performance on Luchins’ (1942) water jar task because high\nWM C solvers tend toward longer solutions, not noticing when\nshorter solutions become available. We present empirical data\nshowing this effect, and a computational model that replicates the\nfindings by choosing among problem solving strategies with\ndifferent WM demands. The high WM C model used a memory-\nintensive strategy, which led to long solutions when shorter ones\nwere available. The low WM C model was unable to use that\nstrategy, and switched to shorter solutions.",
