Problem-solving involves both cognitive and physiological changes. Since most prior work has focused on examining the cognitive side of problem-solving, there is more to explore on the physiological side, including skin conductance. The present study examined skin conductance reactivity (SCR) to the moment participants solved three different types of problems: (a) straightforward (basic), (b) analytic processing (analytic questions), and (c) a sudden insight (riddles). The authors predict different responses in SCR between basic, analytic, and riddle conditions, and the level of difficulty in riddles. Moreover, the authors predict that a faster and correct response is related to larger physiological arousal. Thirty-one participants were confronted with problems that were best solved using either sudden insight (riddles) or analytic thinking, as well as a control condition with basic questions. Participants showed the largest SCR amplitudes to the insight condition versus the basic control condition. Furthermore, hard insight problems had greater SCR amplitudes than easy insight problems. These findings suggest that physiological response to problem-solving is dependent on the type of problem and the amount of challenge it poses to an individual.

解决问题的洞察力与身体唤醒有关

解决问题涉及认知和生理变化。由于大多数先前的工作都集中在检查解决问题的认知方面，因此在生理方面还有更多需要探索，包括皮肤电导。本研究检查了参与者解决三种不同类型问题的那一刻的皮肤电导反应性 (SCR)：(a) 直接（基本），(b) 分析处理（分析问题）和 (c) 突然洞察（谜语）。作者预测了 SCR 在基本、分析和谜语条件之间的不同反应，以及谜语的难度级别。此外，作者预测更快和正确的反应与更大的生理唤醒有关。31 名参与者面临的问题最好使用突然的洞察力（谜语）或分析性思维来解决，以及带有基本问题的控制条件。与基本控制条件相比，参与者在洞察条件下表现出最大的 SCR 幅度。此外，硬洞察问题比易洞察问题具有更大的 SCR 幅度。这些发现表明，对解决问题的生理反应取决于问题的类型及其对个人构成的挑战量。
