Brain’s ‘Visual Dictionary’ Allows Speedy Reading
A recent study has highlighted that human brains are capable of recognizing words which have been read by us some times back in our life. The findings of the study have been published in the annual meeting of the Society for Neuroscience in Washington held on 14th of November.
While commenting upon the findings of the study, Laurie Glezer study leader, “One camp of neuroscientists believes that we access both the phonology and the visual perception of a word as we read it, and that the area or areas of the brain that do one, also do the other”.
According to the scientists, the word that we read gets stored in the “visual dictionary” of our brain. As the word gets stored in the brain, when we read the word again then it allows us to recall it. This is for the very first time when a study has highlighted ability of brain retaining a word in the so-called visual dictionary.
As part of the study, the researchers asked participants to read out few words while there activity of their brain was measured under functional magnetic resonance imaging (fMRI) machine. The fMRI machine is used to measure the blood flow in the brain.
During the study, the participants were asked to read out words which sounded alike. It was found that while articulating the similar sounding words, two different neurons were activated. It means that the two words have been stored in two different areas of brain which helps them in differentiating between different words.
The researchers concluded the study saying that the visual plays greater role in storing words which sounds alike. They also denied the previous belief that sounds of words help people in recognizing and recalling words. It is the visual effects which play the main role in recognizing previously read word.
