“…We exclude that it derived from impaired memory of the group of deaf individuals, since the two groups did not differ in their performance for the space-bisection task. The time-bisection difficulty we observed agrees with research that demonstrates the importance of auditory experience for the development of timing processing skills in other sensory channels 44,45 . For example, both estimation of visual temporal durations in the range of seconds 46 and tactile temporal durations in the range of milliseconds 47 are compromised in deaf adults.…”

It is evident that the brain is capable of large-scale reorganization following sensory deprivation, but the extent of such reorganization is to date, not clear. The auditory modality is the most accurate to represent temporal information, and deafness is an ideal clinical condition to study the reorganization of temporal representation when the audio signal is not available. Here we show that hearing, but not deaf individuals, show a strong ERP response to visual stimuli in temporal areas during a time-bisection task. This ERP response appears 50–90 ms after the flash and recalls some aspects of the N1 ERP component usually elicited by auditory stimuli. The same ERP is not evident for a visual space-bisection task, suggesting that the early recruitment of temporal cortex is specific for building a highly resolved temporal representation within the visual modality. These findings provide evidence that the lack of auditory input can interfere with typical development of complex visual temporal representations.

“…First, we release both the model's code and the dataset used for source spatial localization and the ventriloquist effect study. We foster the value of this dataset in conjunction with the model, as stimuli included in the dataset are a former replica of stimuli often used in psychophysics (e.g., [44,45]). All stimuli included in the dataset were manually recorded within a controlled experimental setting, through which reverberation and luminosity were strictly monitored.…”

Our brain constantly combines sensory information in unitary percept to build coherent representations of the environment. Even though this process could appear smooth, integrating sensory inputs from various sensory modalities must overcome several computational issues, such as recoding and statistical inferences problems. Following these assumptions, we developed a neural architecture replicating humans’ ability to use audiovisual spatial representations. We considered the well-known ventriloquist illusion as a benchmark to evaluate its phenomenological plausibility. Our model closely replicated human perceptual behavior, proving a truthful approximation of the brain’s ability to develop audiovisual spatial representations. Considering its ability to model audiovisual performance in a spatial localization task, we release our model in conjunction with the dataset we recorded for its validation. We believe it will be a powerful tool to model and better understand multisensory integration processes in experimental and rehabilitation environments.
