How hunger affects what we see

We happened: When we're hungry, anything that put us in front is desirable, sometimes even when it comes to dishes that normally would not choose. Or, when we want food, it's easier than a glance out the window of a restaurant we notice what's on the table of diners. This is a scientific reason for being: the hunger affects the perception of anything that is related to food, even of words.

The results of a new research showed how hunger affects what we see. Researchers tested two groups. One of them had lunch and the other had not eaten in four hours. Participants then had to look at words on the computer, at a rate that prevents us from reading them, but that it allows the brain to consciousness of them. A quarter of the words was related to food, and the rest were neutral words. After observing a total of 80 words, subjects were again shown, now calm, that word and one additional word. For example, if shown the first word was "bread" in the second part of the experiment were shown the words "bread" and "glove". Then they were asked what word was originally taught them at high speed. hungry participants performed better and acknowledged they had seen the words related to food, and said these words looked even brighter than neutral words . highly desirable stimuli appear more likely than other types of information to be noticed by our consciousness, the study published in the journal Psychological Science . According to the researchers, this could probably be an important skill of evolution that has prevailed in our nervous systems.
