How you react when faced with written errors can be related to your personality type,according to one study. Researchers at the University of Michigan found that people who get annoyed by errors tend to be introverted(内向的) or have "less agreeable" personalities than those who more easily more that kind of mistakes. 'This is the first study to show that the personalities of listener/readers have an effect on the interpretation of language, " said lead researcher, University of Michigan professor of linguistics and psychology Julie Boland."In this experiment, we examined the social judgments that readers made about the writers." In the study, 83 participants were shown emails written by passible housemates.Some had no errors, while others had either typos ("aslo" instead of 'also") or grammar mistakes ("your" instead of "you're"). The participants were asked to rate the writers in terms of their perceived intelligence, friendliness, trustworthiness and other qualities. Then the participants were asked if they noticed any spelling or grammar mistakes and,if so, how much they were bothered by them. Finally, they were asked to complete the Big Five Personality index (BFI), a 44-question survey that rated them on a scale of extroversion(外向性),agreeability,conscientiousness (being careful to do your work properly),neuroticism(神经) and openness .All the people in the study generally rated the writers with mistakes less favorably than those with perfect letters. Beyond that, they discovered a few key personality traits that seemed to influence how much a few carelessly swapped letters or more serious grammar offenses throw a person's whole world out of order. It turns out that extroverts are more likely to ignore typos and grammatical mistakes than introverts. Also people with "less agreeable" personalities are more sensitive to mistakes than those people who are very agreeable. The researchers say this is "perhaps because less agreeable people are less tolerant of deviations(偏离) from convention."' In other words, bad-tempered people have a harder time than easy-going people dealing with people who break the rules. Both highly conscientious and less open participants were sensitive to typos, but they didn't care all that much about grammar.And,perhaps surprisingly, how neurotic someone was didnt affect how they reacted to grammar and spelling mistakes. So if you have a friend who is constantly pointing out your errors on social media, take comfort in the fact that he is likely a fool, And if it's you who obey every grammar law, then chalk it up to being an introvert .1.
