Scientists discover brain's anti-distraction system
Date:4/18/2014

enior author. "There are individual differences in the ability to deal with distraction. New electronic products are designed to grab attention. Suppressing such signals takes effort, and sometimes people can't seem to do it.

"Moreover, disorders associated with attention deficits, such as ADHD and schizophrenia, may turn out to be due to difficulties in suppressing irrelevant objects rather than difficulty selecting relevant ones."

The researchers are now turning their attention to understanding how we deal with distraction. They're looking at when and why we can't suppress potentially distracting objects, whether some of us are better at doing so and why that is the case.

"There's evidence that attentional abilities decline with age and that women are better than men at certain visual attentional tasks," says Gaspar, the study's first author.

The study was based on three experiments in which 47 students performed an attention-demanding visual search task. Their mean age was 21. The researchers studied their neural processes related to attention, distraction and suppression by recording electrical brain signals from sensors embedded in a cap they wore.
