Comparison of Maturity in Auditory-Visual Multisensory Processes With Sound-Induced Flash Illusion Test in Children and Adults.

Multi-sensory neural pathways of auditory-visual maturation develop before birth in humans. Maturation levels of multi-sensory brain pathways are very different in children in comparison to adults. Auditory sensory neural maturation occurs earlier than visual sensory neural maturation. Auditory-visual multi-sensory processing can assess using objective (event-related potential tests) and subjective (behavioral tests). In this study, we use the sound-induced flash illusion (SIFI) test as a subjective test. The results of the SIFI test show that when the test is complex, the younger children performed not as accurately as the older ones. This difference occurs due to the complexity in the auditory-visual multi-sensory pathway maturation. Therefore, it is necessary to evaluate and analyze the results of different age groups with their normative data.
