Interoception research 40 years later - Revisiting James Pennebaker's critique

Area of Science:

• Psychology
• Neuroscience
• Physiology

Background:

• Critique of five implicit assumptions in interoception research published 40 years ago.
• Assumptions concerned behavioral relevance of autonomic measures, generalization of interoceptive abilities, exclusion of external stimuli, and conscious access to visceral activity.

Purpose of the Study:

• Revisit and evaluate the continued relevance of these historical assumptions for contemporary interoception research.
• Provide inspiration and challenge for the field of interoception.

Main Methods:

• Literature review and critical analysis of interoception research.
• Examination of Pennebaker's expanded model of symptom perception.
• Integration of insights from neuroimaging techniques.

Main Results:

• The five assumptions remain relevant, offering challenges and directions for current research.
• Pennebaker's model highlights the role of cognitive biases, personality, and external stimuli in symptom perception.
• Neuroimaging methods offer new avenues for understanding interoception and mind-body interactions.

Conclusions:

• Interoception research has evolved significantly, addressing earlier critiques.
• Integrating cognitive, personality, and contextual factors is crucial for understanding interoception.
• Brain imaging advances provide novel perspectives on the neural basis of interoception and its connection to behavior and clinical practice.
