I want to know the answer to the following question:
What is the name of the theory Plutchik created?
All the background I'm provided with is that "Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation.". Is that enough to answer the question?
