Final answer:
Anger is often considered a secondary emotion that can be a valid form of communication signaling a need for change, and it can be brought about by primary emotions like fear or frustration.
Step-by-step explanation:
When addressing the question of whether anger is a primary or secondary emotion, and how it functions, it is essential to recognize that anger is often considered a secondary emotion, as it can be brought about by other emotions such as frustration or fear. It's not always an inappropriate emotional response; instead, it can serve as a form of communication signaling that the person feels something in their situation needs to change. These aspects align with the theories of emotion that reflect a combination of physiological arousal, psychological appraisal, and subjective experiences.
Considering the information provided and the understanding of the nature of emotions, the correct answer to the question is Option A, which includes (a) Anger is a secondary emotion, not a primary emotion, (c) Anger is communication that the person feels something needs to change, and (d) Anger is often brought about by other emotions, such as frustration or fear. This answer corresponds with the concept that anger is typically a secondary emotional response to primary emotions like fear or frustration and is often a signal for a needed change.
The James-Lange theory, Cannon-Bard theory, and Two-Factor theory each offer different perspectives on the interplay between physiological responses and emotional experiences, suggesting that emotions are complex and multifaceted.
