Multisensory processing and learning in cognitive development
Auditory dominance in developing children using EEG
Chasing multi-sensory (Audio / Visual) overshadow and interference turned out to be more evasive than thought. We uncovered some functionality that impacted the end result of our experiments and could explain many of the differences among researcher within and across experimental modalities. The variables that affect results one way or another are summarized below
Multisensory Repeat match in children, an EEG study
At the cognitive development lab, I researched, with Dr. Vladimir Sloutsky, multi-sensory processing in children and dominance effect. We conducted a multi-sensory repeat match experiment in children using Electroencephalography (EEG) brain recording ideal for its excellent temporal resolution and ease of setup and comfort. We found that many normal and developing six year old children, when presented with novel visual stimuli together with an auditory one in an immediate recognition task, tend to miss the visual change completely. Their brain patterns, at least early components, are different.
