Study: Visual concentration may leave you temporarily deaf

INDIANAPOLIS (WISH) — A study says visual concentration may leave you temporarily deaf.

According to the Journal of Neuroscience, the brain’s senses of vision and hearing share a limited processing capacity. This sometimes causes the brain to have to choose between them.

One scenario can be when someone is concentrating on their cellphone, they may not hear their friend say their name.

Researchers studied 14 people’s attempt to concentrate on visual tasks while sounds were being made in the background. During the study, the participants monitored their brain activity. They said during the more demanding visual tasks, the brain’s early response of perception was affected.

They said we might not be as good at multitasking as we think.b
