Why Focusing on a Visual Task Will Make Us Deaf to Our Surroundings

Concentrating attention on a visual task can render you momentarily ‘deaf’ to sounds at normal levels, reports a new UCL study funded by the Wellcome Trust.

The study, published in the Journal of Neuroscience, suggests that the senses of hearing and vision share a limited neural resource. Brain scans from 13 volunteers found that when they were engaged in a demanding visual task, the brain response to sound was significantly reduced. Examination of people’s ability to detect sounds during the visual demanding task also showed a higher rate of failures to detect sounds, even though the sounds were clearly audible and people did detect them when the visual task was easy… Read More>>
