Autonomic Multichannel Foundations era
Walter Cannon and Philip Bard anchored the autonomic basis of emotion, guiding the 1948–1965 era toward multichannel measurement by linking visceral states to affective experience. Hans Selye's 1950s general adaptation syndrome highlighted coordinated sympathetic activation, shaping interpretation of galvanic skin response, heart rate, and respiration in psychophysiological studies. William Prokasy and colleagues advanced conditioning paradigms and demonstrated that autonomic responses could be conditioned and measured across multiple channels, including galvanic skin response, heart rate, and respiration. Paul Ekman and colleagues extended the repertoire with facial electromyography to parse discrete affective states, helping establish the multimodal framework that shaped later affective psychophysiology.
Neurovisceral Multimodal Integration era
In the Neurovisceral Multimodal Integration era, Antonio Damasio's somatic marker theory showed how interoceptive bodily states shape cognition and emotion. Stephen Porges' Polyvagal Theory modeled autonomic regulation of social behavior and context-sensitive processing that modulates neural engagement. Thayer and Lane's Neurovisceral Integration Model tied heart rate variability to prefrontal–limbic network control of emotion and executive function, reflecting neuromodulatory influence on behavior. More recent work by Lisa Feldman Barrett on predictive interoception and constructed emotion, together with Aston-Jones and Cohen on locus coeruleus–pupil dynamics and adaptive gain, illustrate the multimodal links between brain, autonomic states, and perception.
