Final answer:
Basic emotions are innate and hardwired into our biology, supported by universal facial expressions studied by researchers such as Paul Ekman and the amygdala's role in the biological basis of emotion. The correct answer is intense.
Step-by-step explanation:
Basic emotions are those that are innate. This means that they are hardwired into our biology and are not learned through experience. Basic emotions, such as happiness, surprise, sadness, fear, disgust, contempt, and anger, are associated with distinct facial expressions which are recognized universally, as studied by researchers like Paul Ekman. Fritz et al. (2009) researched the universal recognition of basic emotions in music, illustrating how inherent these emotions are in our experiences.
Furthermore, the biological basis of emotions, especially fear and anxiety, is strongly related to the amygdala's role within the limbic system, demonstrating how our emotional responses are tied to our brain's structure and function, as noted by Amygdala researchers like Blackford & Pine, and the works of LeDoux and Zajonc on emotion processing emphasize the innate nature of certain emotional responses.
