Kimura's theory of hemispheric specialization, known as the "Dominance Principle," suggests that in situations where different sounds from the two ears are competing for access to the same cortical auditory circuits, the contralateral connections take precedence. This means that the cortical areas in the opposite hemisphere of the stimulated ear will become more active and dominate the processing of the auditory signal. This principle has been supported by various studies, including dichotic listening experiments where participants are presented with different sounds in each ear simultaneously.
