Seeing Through Each Other's Hearts: Inferring Others' Heart Rate as a Function of Own Heart Rate Perception and...

Area of Science:

• Psychology
• Neuroscience
• Social Cognition

Background:

• Social interactions rely on inferring others' emotional states, often through non-verbal cues.
• Interoception, or sensing the body's internal state, is linked to emotions and may be key to understanding others.

Purpose of the Study:

• To investigate the accuracy of inferring others' cardiac states (heart rate) from visual cues.
• To determine if an individual's own interoceptive abilities influence their capacity to infer others' interoceptive states.

Main Methods:

• Replication of studies on visual discrimination of cardiac states.
• Measurement of participants' cardioception performance and self-reported interoceptive accuracy.
• Analysis of the relationship between self-assessed and actual interoceptive abilities and the ability to infer others' heart rates.

Main Results:

• Participants could discriminate others' resting heart rates by visual observation.
• No direct correlation was found between own interoceptive accuracy and inferring others' heart rates.
• Overestimating one's own interoceptive capacities significantly impaired the ability to infer others' heart rates.

Conclusions:

• Beliefs about one's own interoceptive abilities, particularly overestimation, impact the accuracy of inferring others' interoceptive states.
• Deficient self-awareness of interoception may hinder social-emotional understanding.
