This paper introduces a computational framework to measure cardiac interoceptive sensitivity by analyzing heart rate variability and finds it is weak in healthy individuals but varies significantly across participants.

The paper investigates body-wandering during rest, finding it linked to negative affect, autonomic arousal, and reduced social thoughts, while correlating with lower ADHD and depression symptoms.

This paper introduces an automated method to measure respiratory interoception and metacognition using a computer-controlled apparatus.

The paper introduces a psychophysical task to measure cardiac interoceptive beliefs and finds they are biased, less precise, and linked to poorer metacognitive insight.

This study investigates how stimulus valence and arousal affect memory performance and metamemory, finding that negative valence reduces memory and confidence, and influences cardiac activity during recognition.

This study shows that suppressing negative memories affects cardiac responses, with efficient suppression leading to long-term inhibition of cardiac deceleration and ineffective suppression increasing cardiac response.
