London, June 21 (Inditop.com) A recent study shows that we use two separate processes to determine the subtle differences between true and false in our daily lives as opposed to previous views that true and false statements are both processed in the left inferior frontal cortex.
According to researchers from the Universities of Lisbon and Vita-Salute, Milan, determining whether a statement is true involves memory and deciding whether one is false relies on reasoning and problem-solving processes.
In the study, participants were asked to read simple sentences which consisted of a concept-feature pair (for example, ‘the plane lands’) and to decide whether the sentence was true or false.
The current study reveals that false statements activated the right fronto-polar cortex in areas that have been previously related to reasoning tasks.
True statements involved the left inferior parietal cortex and the caudate nucleus.
The study was published in the June issue of Cortex.
