We report an "Aha!" experience which differs from conventional Aha's studied over a century in psychological science. The Aha we introduce is driven by touch instead of the visual and verbal modalities widely studied to date. It can occur when gripping a baseball, with a simple input that the red seam on the ball has a direction. Aided by a symmetry analysis and subsequent survey over literature, we show how our mental and physical representation of a baseball can change suddenly by the seam direction and unravel the factors that make the tactile sense into a joyful-and-insightful sensation. Our study sets a new category of Aha driven by touch, opens a new path to investigate the role of touch in our cognition process, reveals the seam direction as a new degree of freedom in baseball aerodynamics and pitching mechanics, and deepens the insights into throwing a baseball from our fingertips.
我们报告了一种“啊哈！”体验，它不同于心理学界一个多世纪以来所研究的传统“啊哈！”体验。我们所介绍的“啊哈！”体验是由触觉驱动的，而非迄今为止广泛研究的视觉和语言模式。它可能发生在握住棒球时，仅仅是因为球上的红色缝线有一个方向这一简单信息。借助对称性分析以及随后的文献调研，我们展示了我们对棒球的心理和身体表征是如何因缝线方向而突然改变的，并揭示了那些将触觉转化为愉悦且富有洞察力的感觉的因素。我们的研究设定了一种由触觉驱动的新类型的“啊哈！”体验，开辟了一条研究触觉在我们认知过程中作用的新途径，揭示了缝线方向是棒球空气动力学和投球力学中的一个新自由度，并加深了我们对从指尖投出棒球的理解。
