Continuing to explore studies in emotion in the service of my writing plays and teaching playwriting.

Still reading the book on emotion that I bought from Joscephine.

Here are the basic postulates of the psychoevolutionary theory of emotions from the book:

"Postulate 1: The concept of emotion is applicable to all evolutionary levels and applies to all animals as well as humans.
Postulate 2: Emotions have an evolutionary history and have evolved various forms of expression in different species.
Postulate 3: Emotions serve an adaptive role in helping organisms deal with key survival issues posed by the environment.
Postulate 4: Despite different forms of expression of emotions in different species, there are certain common elements, or prototype patterns, that can be identified.
Postulate 5: There is a small number of basic, primary, or prototype emotions.
Postulate 6: All other emotions are mixed or derivative states; that is, they occur as combinations, mixtures, or compounds of the primary emotions.
Postulate 7: Primary emotions are hypothetical constructs or idealized states whose properties and characteristics can only be inferred from various kinds of evidence.
Postulate 8: Primary emotions can be conceptualized in terms of pairs of polar opposites.
Postulate 9: All emotions vary in their degree of similarity to one another.
Postulate 10. Each emotion can exist in varying degrees of intensity or levels of arousal."
