In this contribution, I examine several key publications on the physiology of emotions from the 1860s to the 1930s. I focus on physiologists who studied the emotions prior to and following William James’s 1884 Mind article, by critically reflecting on the conceptual and practical origins and constituents of the Cannon–Bard thalamic theory of emotions. I offer a historical corrective to several major assumptions in our histories of the scientific study of emotions.

In this contribution, I interrogate the historical-intellectual narrative that dominates the history of the Schachter–Singer two-factor theory of emotion. In the first part, I propose that a social influence model became generalized to a cognitive view. I argue that Schachter and Singer presented a cognitive theory of emotions in enacting inside the laboratory Schachter’s preceding “social influence” model of emotions and that Schachter’s adoption of a cognitive model of emotion was driven by and was necessary for his previous research on (...) social influence. In the second part, I argue that the Schachter–Singer theory is remarkable not because it introduced a cognitive turn in emotion, but because it presented sympathetic nervous system activation as an essential constitutive element of every emotion.
