Alcohol narrows field of vision
April 5, 2018, University of Portsmouth
Alcohol can make a person engrossed in an activity oblivious to what's going on around them, no matter how bizarre or unexpected that might be.
New research led by the University of Portsmouth supports the alcohol myopia theory – that alcohol reduces a person's ability to notice more than what's right in front of them.
Dr. Alistair Harvey, a psychologist at the University and lead author, said: "When engrossed in a particular task, we often miss significant events that occur in plain sight – even those so bizarre that they ought to be obvious. Our research found alcohol makes us even more oblivious to our surroundings when our attention is focused in this way.
