Why some people just can't seem to pay attention

Researchers found that individuals with alcoholism exhibited prolonged reaction times and distraction in response to unexpected stimuli. Early onset of heavy drinking during adolescence was also linked to increased distractibility. The study suggests a determinable neurophysiological basis for distractibility in alcoholics.
