In a study published in the journal Psychophysiology, the authors claim to provide the first empirical evidence that viscero-sensory feedback from an internal organ is associated with decision-making processes.Participants with accurate vs. poor perception of their heart activity were compared with regard to their performance in the Iowa Gambling Task.
During this task, participants have to choose between four card decks:
- Decks A and B yield high gains and high losses, and if played continuously, result in net loss
- Decks C and D yield small gains and also small losses, but result in net profit if they are selected continuously
Participants have to learn to avoid the net loss options in favor of the net gain options.
In this study, participants with good cardiac perception chose significantly more of the net gain and fewer of the net loss options.
These findings may provide evidence of the role of visceral feedback in decision-making processes in complex situations.
