![]() ![]() Over the past 40 years, numerous studies have investigated how human perceptual systems coordinate this varied input to create a unified description of reality. People's interpretation of the world depends on information delivered through multiple senses. Evidently, the perceptual system automatically and obligatorily abstracts temporal structure from its visual form and represents this structure using an auditory code, resulting in the experience of “hearing visual rhythms.” Incongruent auditory information significantly disrupted task performance, particularly when presented during encoding by contrast, varying the nature of the rhythm-depicting visual changes had minimal impact on performance. We assessed temporal representations by measuring the extent to which both task-irrelevant auditory information and task-irrelevant visual information interfered with rhythm discrimination. In three experiments, observers judged whether the changes in two successive visual sequences followed the same or different rhythms. Specifically, we investigated whether visually portrayed temporal structure receives automatic, obligatory encoding in the auditory domain. We asked whether this sensory specialization results in cross-modal encoding of unisensory input into the task-appropriate modality. When the senses deliver conflicting information, vision dominates spatial processing, and audition dominates temporal processing. ![]()
