Key result
A multivariate dimensional approach in 51 participants showed that autonomic and subjective emotional responses could be adequately described in a two-dimensional affective space.
Why the study?
Experimental studies provide little evidence of coherence between subjective and autonomic responses during emotional states, largely due to univariate approaches or limited multivariate analyses evaluating them separately.
Observational (n=51)
The study demonstrates that while there is some coherence between autonomic and subjective emotional responses, there is also substantial autonomic structure that does not covary with subjective experience.

Highlights independent autonomic structure beyond subjective emotion; extends affective models but leaves clinical translation open.
A central tenet of many theories of emotion is that emotional states are accompanied by distinct patterns of autonomic activity. However, experimental studies of coherence between subjective and autonomic responses during emotional states provide little evidence of coherence. Crucially, previous studies investigating coherence have either adopted univariate approaches or made limited use of multivariate analytic approaches by investigating subjective and autonomic responses separately. The current study addressed this question using a multivariate dimensional approach to build a common autonomic-subjective affective space incorporating subjective responses and three different autonomic signals (heart rate, skin conductance response, and pupil diameter), measured during an emotion-inducing task, in 51 participants. Results showed that autonomic and subjective responses could be adequately described in a two-dimensional affective space. The first dimension included contributions from subjective and autonomic responses, indicating coherence, while contributions to the second dimension were almost exclusively of autonomic covariance. Thus, while there was a degree of coherence between autonomic and subjective emotional responses, there was substantial structure in autonomic responses that did not covary with subjective emotional experience. This study, therefore, contributes new insights into the relationship between subjective and autonomic emotional responses, and provides a framework for future multimodal emotion research, enabling both hypothesis- and data-driven testing.
