In this SE question about "What causes emotions?", there are two answers, one which discusses the distinction between basic emotion theorists (Ekman) and constructionists (Russell, Watson), and the other which discusses a set of theories of emotions which seem to have no relation with the theories of the first answer (James-Lange-Theory, Cannon-Bard-Theory, Schachter-Singer-Theory).
How are related basic/constructionist theories of emotions and James-Lange-Theory/Cannon-Bard-Theory/... of emotions?
And also the conceptors of the James-Lange-Theory, Cannon-Bard-Theory, Schachter-Singer-Theory seem to be born a long time ago, so I wonder if the theories are outdated.
