Researchers have been studying the differences between cultures and the effects that those cultures have on the brain. It was hypothesized that in Western cultures there is more of an independent self-identification and in Asian cultures there is an interdependent self-identification. Researchers Ying Zhu, Li Zhang, Jin Fan, and Shihui Han put their skills together to come to a conclusion for this hypothesis.
Tests were performed on paid volunteers. Thirteen volunteers were men and women from a Chinese college and the other thirteen were men and women from a Western college. The researchers used fMRIs to measure brain activity of the participants. The participants were asked to judge words shown to them on a screen and describe whether they were accurate descriptions of themselves, their mothers, or others. An example of a word would be the names of the presidents of both countries. They were also asked to judge the font of the words. The results were that the medical prefrontal cortex (MPFC) and the anterior cingulate cortex (ACC) activated more with self than other identification for both parties. However, the MPFC was activated with both mother and self in Chinese subjects and just self in Western subjects. This shows that the MPFC of Chinese individuals represents both the self and the mother, while the MPFC of Western individuals exclusively represents self.
By studying both of these cultures it found that there are varying cultural differences in brain activity with self representation. Asian cultures have more of a group identification while Western cultures have a self identification. Because of the dynamic of Asian cultures there is no mental separation of identity. It is normal in Asian cultures for families to live together continuously. This is almost unheard of in most Western families. It is normal for children to move out when eighteen and not move back in. This helps to forge a self identification in Western individuals.

Reflection:
I chose to include how the research was conducted and how participants were elected. I did not explicitly answer the five critical questions because I believe that if you are reading a summary of information those questions should be able to be answered in the summary. Overall the news article was lacking in information provided in the scholarly article. The news article focused on explaining what cultural neuroscience was and not on the research done to find cultural effects on the brain. The news article was not reliable and did not speak about how volunteers were found and how the experiment was conducted. I learned that journalists write to their audience. The scholarly article would not be easily understood by someone with no background in psychology. The news article explained a small portion of the scholarly article and then explained neuroscience in the way that most people could understand. The scholarly article writers aimed their writing towards other psychologists that could understand their experiments and work. When I was writing this I was trying to break down what I read in the scholarly article and make it easier to read for someone who does not have that much of a background in psychology. Unlike the pop culture article I stayed along the lines of the actual experiment happening in the scholarly article. It was fairly difficult to decide what I wanted to include in my summary of the article. A lot of what I read would not make sense to somebody who has not been doing research in psychology.
