A study recently published in eNeuro specifies that processing specific factual information provokes more robust activity in the brain compared to indefinite or unclear information.
Modal language such as "might" and "may" allows humans to guess the possibilities in both the actual world and the fictitious ones.
For example, when reading a story, the brain is adding new information to a model of developing situation. However, not all information is sure.
Neuroscience reported that "Tulling et al. used magnetoencephalography to compare" the manner of processing of "factual and modal language in short narratives."
Factual and Modal Sentences
Factual sentences comprised the verb "do," and modal sentences are composed of the verbs "may," "might," or "must."
Meanwhile, factual sentences prompted stronger activity in the brain compared to modal sentences within 200 milliseconds of the target verb that appears.
This then proposes that the brain was adding the factual but not unsure information to its model of the given situation.
However, the place of the increased activity varied, possibly because of perspective. Updating the depiction of the beliefs of a story character increased activity in "right temporoparietal areas" while updating an individual's own increased activity in frontal medial parts.
These research findings proposed that the human brain comprises a strong, perspective-regulated neural depiction of factual information, not to mention more indefinable cortical indications that reflect the calculation of possibilities.
Studying Contrast Through Language
According to the study, a guarantee of human thought is the ability to think not just about the actual or real world, but about alternative ways too, and this world could be.
The study authors said, one way of studying such a contrast is through language. Language comprises grammatical devices for conveying possibilities and necessities like the words "must" or "might."
With the devices also known as "modal expression," actual against possible contrast can be studied in a highly-controlled manner.
Factual expressions, on the other hand, update a discourse model's here-and-now. For example, the statement, "There's a snake under the table," is factual. Meanwhile, the sentence, "There might be a snake under the table," is its modal version.
Magnetoencephalography or 'MEG' Use
The study authors used the MEG or magnetoencephalography to examine if the process of discourse updating, as well as the modal displacement, detach or distance the brain.
Essentially, factual or modal expressions were inserted in short narratives, and through two investigations, factual utterances increased the gauged activity over modal statements.
Nevertheless, such a localization of the increase seemed to rely on perspective: gesturing localization in temporoparietal locations rose when updating the illustration of someone else's opinions and perceptions. At the same time, frontal medial areas appear sensitive to updating the beliefs of an individual.
As indicated in the study, the modal displacement's presence did not elevate the signal strength of the MEG in any of the investigators' analyses.
In all, the study determines possible neural signatures of the process by which facts are getting to humans' mental depiction of the world.
Typically, one is easily able to find the difference between mere possibility, although there is a little knowledge about the neural mechanisms that enable him to do so.
As a result, the study found that the brain is responding differently to expressions about "here-and-now" compared with expressions that deliver possibilities.
Meaning, a person's brains separate factual information from the hypothetical one, bringing interesting new questions on the depiction of probabilities in discourse comprehension.
