Many things in our daily life have emotional significance for us. For example, if a pair of wool socks is the last thing Grandma knits before she dies, it has emotional value. The same applies to words. A stranger's name has no emotional value at first, but if you develop a romantic relationship with him or her, the same name suddenly has a positive connotation. Recently, researchers at the University of Gottingen in Germany studied how the brain handles these positive or negative stimuli. The results were published in the Journal of Neuropsychology. In the

study, scientists at the George Elias Miller Institute of Psychology at the University of Gottingen analyzed how people associate neutral symbols, words and expressions with emotional meaning. Within a few hours, participants learned these connections through systematic rewards and punishments. For example, if they always receive money when they see a neutral word, then the word gets a positive association. However, if they always lose money when they see a word, it will lead to the word being associated with negative associations. Studies have shown that people learn positive associations much faster than neutral or negative associations, meaning that positive things are quickly associated with a word or a person's face (as their recent study in the Journal Neuroimage shows). Researchers also used electroencephalogram (EEG) to study how the brain processes various stimuli. The results show that the brain usually determines whether an image or word is positive or negative after 200 to 300 milliseconds. Dr Louisa Kulke, the lead author of the study, said: "Loss-related words cause specific neurological responses in the visual cortex after 100 milliseconds." "So the brain instantly recognizes what a newly learned word means to us, especially when it means negative."

In addition, whether the word corresponds to real objects (such as chairs or trees) or whether it is a fictional word (such as Napo or foti) that does not exist in language also seems to have an impact. Therefore, the existing semantics of a word seem to play a role in the emotions we associate with it. < p > < p > Compilation: Max < / P > < p > Reviewing: alone < / P > < p > Compilation: Nanxi < / P >
