Judgment and decision-making: brain activity indicates there is more than meets the eye

People make immediate judgments about images they are shown, which could impact on their decisions, even before their brains have had time to consciously process the information, a study of brainwaves led by The University Of Melbourne has found.

Published today in PLOS ONE, the study is the first in the world to show that it is possible to predict abstract judgments from brain waves, even though people were not conscious of making such judgments. The study also increases our understanding of impulsive behaviours and how to regulate it.
