Where is an emotion? Using an emotional spatial cueing task to test for emotional localization following targeted...

The relationship between emotion and attention is vital for adaptation. Trained attention to bodily sensations can heighten emotional awareness, including during "visceroception" (sensing the viscera, principally the heart, lungs and gut), which has been linked to emotion intensity and regulation. However, it is not always clear when bodily attention is adaptive, and useful to maintain, or maladaptive and best inhibited. The current study, part of a wider exploratory project, investigates "localized emotion" in this context. Localized emotion is a novel construct, articulated within the project, and suggested to be manifested within a visceroceptive system: targeted visceroception could result in disinhibited attention to localized emotion. In particular, whilst evidence points to the importance of the gastrointestinal tract for emotion (e.g., gut biome, enteric nervous system), gut sensations are often barely detectable, consistent with an inhibition process. An emotional spatial cueing task was used to test for localized effects within several groups: one trained for 8 weeks to focus on their lower abdomen (gastroception), with another focused on their chest cavity (cardioception), plus a control group. The spatial cueing task involved rapid responding to the detection of bodily feelings following the presentation of an emotional picture. Participants then indicated on a body map where they had detected the feeling, followed by corresponding valence and arousal levels (i.e., core affect) on a self-assessment manikin. Data were analyzed using generalized estimating equations. There was some support for localization in the gastroception group relative to the chest-focused group and controls. Gastroception-related findings included: greater improvement in interoception (interoceptive sensibility), slowed reaction times, a cluster of lower abdominal detections on a body map, changes in core affect, and indications of improved emotion regulation. Attending to the gut may play a key role in improving one's ability to access emotional feeling, with associated implications for emotion regulation.
