Protecting against mental impasses: Evidence of selective retrieval mitigating the impact of fixation in creative...

A common issue in creative problem solving is the unintended fixation on strongly associated, yet inappropriate solutions. In two experiments, we investigated whether lowering their accessibility by means of selective retrieval can positively affect subsequent problem-solving performance in a Compound Remote Associate test. Misleading associates were strengthened by letting participants memorize them alongside with neutral words. Half of the participants then selectively retrieved the neutral words in a cued recall test, temporarily weakening the activation level of induced fixation. In both experiments, this resulted in less impairment of subsequent performance for fixated CRA problems in early problem-solving stages (0-30 s). Additional results further revealed that participants who had engaged in prior selective retrieval perceived an increased feeling of having had immediate access to target solutions. These findings correspond to the assumption of inhibitory processes being a critical factor in both retrieval-induced forgetting and overcoming fixation in creative problem solving or preventing it from occurring in the first place. Also, they provide important insight into how strongly problem solving success is influenced by fixation.
