Summary
This study shows that people adjust their breathing rate to match a virtual avatar, demonstrating visuo-respiratory conflict resolution. This finding has implications for understanding body perception and potential clinical applications.
Area of Science:
- Neuroscience
- Psychology
- Virtual Reality
Background:
- Interoception plays a key role in body perception and the sense of self.
- Virtual reality (VR) is used to study body ownership illusion (BOI), but research on interoception and BOI is limited.
- Existing BOI research primarily focuses on exteroceptive senses, neglecting interoceptive influences.
Purpose of the Study:
- To investigate the resolution of visuo-interoceptive (visuo-respiratory) conflicts.
- To determine if participants adjust their respiration rate (RR) in response to a virtual avatar's breathing.
- To explore the role of interoception in body perception within a VR environment.
Main Methods:
- A within-subjects experimental design was employed using a VR system connected to a respiration monitor.
- Participants observed a virtual avatar breathing in sync with their own RR, followed by conditions where the avatar's breathing rate changed.
- Changes in participants' RR were measured as the dependent variable, analyzed via linear regression slopes.
Main Results:
- Participants significantly adjusted their RR in response to visuo-respiratory conflicts, with changes in the predicted direction.
- Average RR decreased by 0.48 breaths/minute and increased by 0.64 breaths/minute in the respective conditions.
- The observed changes in RR were statistically significant, indicating effective conflict resolution.
Conclusions:
- The study demonstrates visuo-respiratory conflict resolution, where individuals synchronize their breathing with a virtual avatar.
- Even small changes in RR, like 1 breath/minute, were observed, suggesting clinical significance.
- Findings suggest interoception is crucial for body perception and may have applied significance in therapeutic interventions.

64.3K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

01:27Air-entraining Agents
262
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Overview of the Respiratory System and Energy Production
Energy production in the human body is primarily fueled by oxidation, a process where food molecules are burned by combining with oxygen to produce carbon dioxide and water. This vital metabolic process sustains life, and is supported intricately by the respiratory system.

375
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Cellular respiration is a fundamental metabolic process that enables organisms to generate energy from organic molecules. One of its central pathways is the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle, which plays a crucial role in energy production and biosynthetic processes.Conversion of Pyruvate to Acetyl-CoAThe pyruvate generated from glycolysis undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, producing acetyl-CoA, one molecule of NADH, and one...
