By the term emotional state, in simple words, we understand how a person feels at a given moment. From the point of view of a more precise description within the framework of this project, the emotional state of a given person at any moment is described by a biochemical quantity, which we call the emotional vector. A vector means that this quantity has a number of components - an emotional state consists of a number of negative and positive emotions:
E = (en1, en2, ....ep1, ep2)
where enx are negative components of emotion and epx are positive components of emotion.
An example of the negative components of an emotion can be, for example, en1 = stress - represented by the concentration of stress hormones, or en2 = fear represented by the activity of a nervous structure called the amygdala. In any case, we consider the individual components of the emotional vector to be objectively measurable biochemical quantities.
In this approximation, the individual components are already simple (scalar) values that take on positive values between zero and enmax.
