East Asians seem more modest, but psychological research shows that they are just as proud and confident as they are from other cultures. A research team recruited 40 volunteers to participate in the research, half of them from East Asian countries, and the rest From Western countries. They showed a lot of positive and negative words to these volunteers and asked them which adjectives are suitable for them. As a result, no matter what cultural background the volunteers have, they tend to use more positive adjectives Describe yourself and think that some of the more negative characteristics are not suitable for you. Researchers believe that this shows that people who participate in the test have the same motivation to beautify themselves regardless of their cultural background. Which of the following, if true, would most weaken the argument:. ['East Asians are used to negatively evaluating themselves, while Westerners often overstate their abilities.', 'When volunteers are asked to describe themselves in positive words, their responses are the same.', 'East Asians are only a cultural convention, they have the same self-esteem as Westerners.', 'Research finds that volunteers have similar brain waves regardless of their cultural background.']
