“…In both cases, the focus is upon associative processes among verbal stimuli, the focus of interest in the present study and others (e.g., Haarmann, George, Smaliy, & Dien, 2012;Storm & Koppel, 2012). Because solutions to RAT problems are susceptible to competitive interference effects, it has been possible to block or interfere with RAT problem solving performance by priming inappropriate (nonsolution) associates, resulting in fixation effects (e.g., Dodds, Smith, & Ward, 2002;Kohn & Smith, 2009;Smith & Blankenship, 1991;Vul & Pashler, 2007). In the present set of experiments, we again took advantage of the verbal and associative nature of the RAT problems to examine the effects of hints in the form of semantic associates of solution words on impasse resolution in RAT problem solving; does spreading activation from such hints cause incubation effects?…”
