Quasi-emotions?

What are ‘quasi-emotions’? Are they lesser forms of ‘natural’ emotions, or different from emotions all together? What would such a thing look like? How do they manifest themselves? How does one experience them? The entire idea of 'quasi-emotions' sounds quite confusing and unnecessary to me. I think emotions are what emotions are, and that you can't have a different 'type' of emotion. If that is what 'quasi-emotions' are, different types of regular emotions, then I simply cannot believe that they exist. A person is either feeling something or they are not. There is no in-between there. However, I will concede that emotions can be measured as if on a scale. There can be and if fact there are various degrees of emotion that can be felt differently by various individuals. For instance, if you take a look at the general emotion of 'anger', you will clearly find varying degrees of it. Being annoyed, irritated, frustrated, mad, angry, irate, furious, etc. So, if the term 'quasi-emotions' means simply a lesser degree of an emotion, such as being annoyed rather then furious, then that seems to make perfect sense. And yet, if you look up the word 'quasi', you are very likely to find a definition like 'partly', 'almost' or 'seemingly'. But can you 'almost' have an emotion? Or 'seemingly' have one? How can you 'partly' feel sad, or angry, or happy, or scared? That doesn't make sense at all. If the author does in fact mean a less intense form of an emotion by the term 'quasi-emotion', then why not say simply that? Because certainly the term 'quasi' by itself means no such thing.
