Classical views suggest that experienced affect is related to a specific bodily response, whereas recent perspectives challenge this view postulating that similar affective experiences rather evoke different physiological responses. To further advance this debate in the field, we used representational similarity analysis to investigate the correspondence between subjective affect (arousal and valence ratings) and physiological reactions (skin conductance response [SCR], startle blink response, heart rate, and corrugator activity) across various emotion induction contexts (picture viewing task, sound listening task, and imagery task). Significant similarities were exclusively observed between SCR and arousal in the picture viewing task. However, none of the other physiological measures showed a significant relation with valence and arousal ratings in any of the tasks. These findings are discussed within the framework of the Populations hypothesis, suggesting that physiological responses do not depend on the experienced affect but are directly associated with the context in which they are evoked.
经典观点认为，经验性情感与特定的身体反应有关，而最近的观点则对这一观点提出了挑战，认为相似的情感体验会引起不同的生理反应。为了在该领域进一步推进这一辩论，我们使用表示相似性分析来研究主观情感（唤醒和效价评分）与生理反应（皮肤电导反应 [SCR]、惊跳眨眼反应、心率和皱眉肌活动）在各种情感诱导情境（图片观看任务、声音聆听任务和意象任务）之间的对应关系。仅在图片观看任务中观察到 SCR 和唤醒之间存在显著相似性。然而，在任何任务中，其他生理测量都没有显示与效价和唤醒评分有显著关系。这些发现是在群体假设的框架内讨论的，该假设表明生理反应不依赖于所经历的情感，而是直接与引起它们的情境相关。
