On the Role of Interoception in Body and Object Perception: A Multisensory-Integration Account

1Department of Psychology, University of Würzburg.
Summary
Embodied perception links body sensations and environmental perception. Integrating internal body signals (interoception) with external sensory data explains how our body influences what we see and vice versa.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Sensory Integration
Background:
- Embodied perception phenomena demonstrate bidirectional influence between body sense and environmental perception.
- Examples include phantom limb sensations and altered time perception of self-movements.
Purpose of the Study:
- To propose a unified mechanistic explanation for embodied perception phenomena.
- To frame these phenomena as instances of multisensory integration.
Main Methods:
- Review and synthesis of existing research on embodied perception.
- Theoretical framework development integrating interoceptive and exteroceptive signals.
Main Results:
- Embodied perception arises from multisensory integration of interoceptive (body) and exteroceptive (environment) signals.
- This integration provides a mechanistic account of how body and environment mutually shape perception.
Conclusions:
- The proposed framework offers a parsimonious explanation for diverse embodied perception effects.
- Challenges traditional views emphasizing body ownership, agency, or action-specific scaling.

01:11Sensory Perception: Organization of the Somatosensory System
4.8K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

570
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

01:15Sensory Modalities
1.5K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:33Somatosensation
38.2K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:26Introduction to Special Senses
6.1K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

01:31What is a Sensory System?
96.0K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.
