Exposure to bright light can be visually aversive. This study explored the association between light aversion and various facets of impulsivity. A total of 1,245 participants completed the UPPS-Impulsive Behavior Scale to assess five facets of impulsivity. Additionally, participants responded to questions regarding their aversion to light (e.g., how aversive do you find bright light?). Spearman's correlation coefficients (rho) revealed that individuals who find light physically aversive, or who experience a negative physical response to exposure (e.g., nausea or headache) triggered by bright indoor light or sunlight, tend to act impulsively under extreme negative and positive affect. Individuals who experience a negative physical response to exposure display greater premeditation, indicating a higher likelihood of considering the potential consequences of their actions. Moreover, these individuals score lower on sensation-seeking, suggesting a reduced inclination to seek out thrilling or novel experiences. These results reveal a complex relationship between light aversion and impulsivity, where those who find light aversive tend to be less impulsive in general, but more impulsive under extreme positive or negative affect.
暴露在强光下在视觉上可能令人厌恶。本研究探讨了对光的厌恶与冲动性的各个方面之间的关联。共有1245名参与者完成了UPPS冲动行为量表，以评估冲动性的五个方面。此外，参与者回答了有关他们对光的厌恶程度的问题（例如，你觉得强光有多令人厌恶？）。斯皮尔曼相关系数（rho）显示，那些觉得光在生理上令人厌恶的人，或者那些在暴露于明亮的室内光或阳光时会产生负面生理反应（如恶心或头痛）的人，在极端消极和积极情绪下往往会冲动行事。对暴露有负面生理反应的人表现出更强的预谋性，这表明他们更有可能考虑自己行为的潜在后果。此外，这些人在寻求刺激方面得分较低，这表明他们寻求刺激或新奇体验的倾向较低。这些结果揭示了对光的厌恶与冲动性之间的复杂关系，即那些觉得光令人厌恶的人总体上往往不那么冲动，但在极端积极或消极情绪下更冲动。
