Emotional arousal refers to the level of activation or intensity of an individual's emotional response to a stimulus. This research area examines how different factors, such as personal experiences, environmental cues, and cognitive processes, can impact an individual's emotional arousal. Researchers may investigate the physiological changes that occur during emotional arousal, such as changes in heart rate or hormone levels, as well as the cognitive processes that influence emotional responses. Understanding emotional arousal can provide insights into how emotions impact behavior, decision-making, and overall well-being.
