Summary
Training can improve multisensory integration, the process of combining sensory information. While task-specific feedback training shows promise, its generalizability requires further study, with exercise-based interventions also emerging as a potential avenue.
Area of Science:
- Cognitive Neuroscience
- Perception Psychology
Background:
- Multisensory integration, crucial for daily activities, declines with age and is impaired in neurodevelopmental conditions like dyslexia and autism.
- The potential for training to enhance multisensory perception remains an active area of research, particularly for improving cognitive function in affected individuals.
Approach:
- A systematic review was conducted, analyzing 27 studies selected from 1521 identified across major scientific databases.
- Study quality was rigorously assessed using established tools like MINORS and Cochrane Risk of Bias tool 2.0.
Key Points:
- Considerable evidence supports that in-task feedback training, utilizing psychophysics protocols, effectively improves multisensory task performance.
- The generalizability of such training to broader multisensory integration tasks yielded inconclusive results, with mixed findings across studies.
- Exercise-based training presents promising preliminary findings, suggesting physical activity protocols as a viable future direction for enhancing multisensory integration.
Conclusions:
- Multisensory perception can be trained, particularly through task-specific feedback methods.
- Future research should explore the efficacy of training protocols in clinical populations and individuals with impaired multisensory integration.
- Investigating exercise-based interventions warrants further attention as a potential non-pharmacological approach to improve multisensory processing.

3.2K
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...

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...

01:31What is a Sensory System?
95.4K
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.
