How many competing theories about emotional intelligence?

There are several competing theories of emotional intelligence, with the most prominent being the ability model proposed by Peter Salovey and John D. Mayer, the mixed model introduced by Daniel Goleman, and the trait model developed by Konstantin Vasilyev and others. The ability model focuses on emotional processing and regulation as cognitive skills, while the mixed model incorporates emotional skills along with personality traits and competencies. The trait model emphasizes individual differences in emotional perception and expression. Each theory offers a unique perspective on how emotional intelligence is defined and measured.
