Final answer:
Boredom is an example of an unpleasant, low-arousal emotion, unlike delight and contentment, which are pleasant, and anger, which is high-arousal. Emotions are subjective experiences influenced by individual appraisal, expression, and physiological responses.
Step-by-step explanation:
An example of an unpleasant, low-arousal emotion is boredom. Emotions can be categorized by their valence (pleasant or unpleasant) and level of arousal (low or high). While emotions like delight and contentment are pleasant, and anger is a high-arousal emotion, boredom is characterized by being not only unpleasant but also low in arousal, lacking stimulation or interest. Understanding emotions is critical, as they are subjective states that result from a combination of subjective experience, expression, cognitive appraisal, and physiological responses. The study of emotions includes the well-recognized universal emotions which, according to research by Ekman and others, include happiness, sadness, anger, fear, disgust, and surprise, and are expressed similarly across different cultures.
