Week 1
During the first week, I started my summer lab study with my professor. We met on Monday, June 24th in Harvard Medical School to talk about what we are going to do for the four-week session. He was so nice that he answered every question from me such as what my research topic could be. After the meeting, I received the paper that I was going to study from my teacher.
在第一周，我开始了我的夏季实验室的研究与我的老师。我们于6月24日星期一在哈佛医学院会面，讨论我们将在为期四周的会议上做些什么。他太好了，他回答了我的每一个问题，比如我的研究课题。会后，我收到了我要从老师那里学习的论文。
The paper is about decision-making in the adolescent brain. I spent the next few hours on studying this paper as well as doing my homework from my university and I really enjoy the time! The difficulty of reading this paper is a little hard for me since there were several professional words that I wasn’t familiar with. Therefore, when I read the paper, I also made many notes which enabled me to better organize the information as well as extract questions.
本文是关于青少年大脑中的决策问题。我花了一些时间学习这篇论文，同时也做我的大学作业，我真的很享受时间。读这篇论文的难度对我来说有点难，因为有几个我不熟悉的专业词汇。因此，当我读论文的时候，我也做了很多笔记，使我能够更好地组织信息和提取问题。
To illustrate, I found that ventromedial prefrontal cortex and ventral striatum played significant roles in controlling people’s impulsivity & inhibitory, learning & prediction errors as well as emotion on decisions. Then several questions came to my mind. According to the paper, the previous study claimed that for people between 11- 31, in average, with the increase of their age, the impulsive choice will decrease due to the activity of the left vmPFC and ventral striatum. I’d like to figure out how about those who are over 30 years old? In addition, recent research indicated that adolescents tend to express more risk behaviors than people from other age groups. Thus, suppose an adolescence avoided risk behavior, is that mean this person will behave much more “mature” than the peers? There are inconsistent outcomes in adolescence behavior studies, so I also believe much further study should be developed. Finally, Why the uncommon activity in ventromedial prefrontal cortex and ventral striatum happened during adolescence? Does dopamine influence the brain activity or there’s other hormones should be responsible? Except for the topic, I notice that there’s an interesting phenomenon from the paper that why young adults (between 17-21) show less peer effect than both adolescents and adults? What’s the factor that causes this specific age group is impacted less by peer effect? I’m interested in looking into this question. Due to the schedule limitation, I prefer to conduct survey questions for three age groups: adolescents, young adults and use simple random sample/convenience sample. I’m going to review previous research to complete my study plan in two days as well. For the next week, I will discuss with the teacher about this and start collecting samples. I’m very looking forward to the future studies!
为了说明，我发现腹内侧前额叶皮层和腹侧纹状体在控制人们的冲动性和抑制性、学习和预测错误以及情绪上起着重要的作用。然后我想到了几个问题。根据该文献，先前的研究表明，对于年龄在11岁到31岁之间的人来说，随着年龄的增长，冲动的选择会由于左侧VMPFC和腹侧纹状体的活动而降低。我想知道30岁以上的人怎么办？此外，最近的研究表明，青少年倾向于表达比其他年龄组的人更危险的行为。因此，假设青少年避免冒险行为，这是否意味着这个人的行为会比同龄人更成熟？青少年行为研究的结果不一致，我认为还需要进一步研究。最后，为什么在青春期前腹内侧前额叶皮层和腹侧纹状体发生了罕见的活动？多巴胺是否影响大脑活动或其他激素应该负责？除了这个话题之外，我注意到有一个有趣的现象，为什么年轻的成年人（17-21岁）的同伴效应比青少年和成年人都要少？是什么因素导致这个特定年龄组受同伴效应影响较小？我对这个问题感兴趣。由于时间表的限制，我更喜欢对三个年龄组进行调查问卷：青少年，年轻人，并使用简单的随机抽样/便利样本。我将回顾以前的研究，在两天内完成我的学习计划。下周，我将和老师讨论这个问题，开始收集样品。我非常期待未来的学习！
Week 2
Another tough week will be over. During this week, I also learned a lot that not only from my study, but also from the things I experienced these days.
另一个艰难的一周即将结束。在这一周里，我学到了很多东西，不仅来自于我的学习，也来自于我所经历的事情。这些天。
For the second week, I started collecting the sample for discovering the relationship between peer influence and self-decision making among young adults. I use questionnaires for collecting data and the questionnaire includes some background information such as age, gender, culture as well as the questions for identifying participants’ preference to self-decision and peers. Although only 40 samples should be included in the study, I experienced a really, really hard time on sample collecting.
第二周，我开始收集样本来发现同伴影响和自我决策之间的关系。在年轻人中。我用问卷调查收集数据，问卷包括一些背景信息，如年龄，性别、文化以及识别参与者对自我决策和同龄人偏好的问题。虽然只有40个样本应该包括在研究中，我经历了一个非常，非常困难的时间收集样品。
The temperature was too high in Boston from Monday and Wednesday. Every person in the street walked in a hurried pace and I couldn’t bear to stop them to do the questionnaire. Wednesday was the Independence Day, so no students would go to school. Therefore, although I got the printing paper of the questionnaires from my professor on Monday, I chose to write the introduction part of the study. I was very busy on Thursday and Friday because I went to Harvard, MIT, Boston College, Berklee College of Music, Northeastern University, Boston Public Library and Boston University for collecting the data, but the efficiency on collecting the samples was still slow. Harvard and MIT are both good places to study because normally, people expected that the students there must have great abilities in self-decision making. However, unfortunately, there were only a few students there when I arrived. There were only some visitors in the campus, so I got very few samples in these two universities. In the other universities, there were more students. Nevertheless, there were some students who I couldn’t interrupt: those who walked and chatted with their friends and the student sit in the café but wore the headset. Also, I always feel really nervous when I talk to people I’m not familiar with. I was pleased with the progress that I became much braver during these days although this was still a hard thing to me. Learning from the textbook is essential, but stepping forward from life is also a significant part, isn’t it?
从星期一到星期三，波士顿的气温太高了。街上的每个人都走得很匆忙，我不能。忍受他们做问卷调查。星期三是独立日，所以没有学生会去上学。因此，虽然星期一，我收到了我的教授的问卷，我选择写这篇文章的部分。星期四和星期五我很忙，因为我去了哈佛大学，麻省理工学院，波士顿学院，伯克利音乐学院，东北部。波士顿大学、波士顿公共图书馆和波士顿大学收集数据，但采集样品的效率仍然很低。哈佛和麻省理工都是学习的好地方，因为人们通常认为那里的学生必须有很强的能力。自我决策。然而，不幸的是，当我到达时，那里只有几个学生。校园里只有一些游客，所以我得到了这两所大学的样本很少。在其他大学里，有更多的学生。尽管如此，还是有一些学生无法中断：那些和朋友一起散步聊天的学生和学生坐在咖啡馆里，戴着耳机。而且，我总是感觉当我和我不熟悉的人交谈时，我真的很紧张。我很高兴在这些日子里我变得更加勇敢。虽然这对我来说仍然是一件很难的事情。从教科书中学习是必要的，但从生活中走出来也是重要的一部分。不是吗？
Finally, another good idea came to my mind was that since there are many young adults (most are college students) in my apartment, I decided to ask these people to do the questionnaires. It was exciting that these people were so nice, and it didn’t take much time on finishing the rest questionnaires.
最后，我想到另一个好主意，因为在我的公寓里有很多年轻的成年人（大多数是大学生）。决定请这些人做问卷调查。令人兴奋的是，这些人都很好，而且花的时间不多。完成其余的问卷调查。
For the next few days, I’m going to analyse the data and find out whether there’s any point that is interesting to study. Hope everything will go well!
在接下来的几天里，我将分析数据，找出是否有任何有趣的研究点。希望一切会好起来的！
Week 3
First, sorry for writing the report late this week. I just finished my draft of my paper on Friday. The third week of this summer lab study was also very busy and meaningful for me. During the first three days, I figured out that my research hypothesis should be that in young adults, there would be observed differences in the relationship between self-decision making and peer influence, depending on their field of study or gender. I recorded the data of the 93 samples by calculating the mean scores of their answers in the questionnaires into the Excel. Later, except the introduction of the paper, I wrote the method part of this study to record the participants, apparatus and materials, and the procedure of my sample collecting.
首先，很抱歉这个星期晚些时候写报告。我刚刚完成了星期五论文的草稿。今年夏季实验室研究的第三周我也很忙，很有意义。在最初的三天里，我发现我的研究假设应该是年轻人，在自我决策和同伴影响之间的关系会有所不同，这取决于他们的学习领域。或性别。我将93个样本的数据记录在EXCEL中，将其答案的平均分数计算出来。后来，除了论文的介绍之外，我还写了本研究的一部分来记录参与者、仪器和材料，以及我的样品收集程序。
I met with the professor and TA R on Wednesday for asking the statistic method and how to compare the sample groups. Both of them were so kind that provide great suggestions for me, which enabled me to have clear and straightforward thoughts on the next steps. Therefore, on Thursday and Friday, I finished analysing the data (participants’ ages, college major, the scores of self-decision questionnaire and peer-influence questionnaire) by SPSS. The participants were divided into two group: college major group that contains people from the college of business, college of engineering, and college of liberal art& science and the gender group (males and females). Depend on the graph and the correlation coefficient of each group, I found that my hypothesis was partly corresponding. To illustrate, there were moderate differences between the three major groups: compared to college of liberal art & science, young adults from college of engineering and college of business performed positive relationship on the scores between peer influences and self-decision makings, which meant that people who had more same opinions and belief with the peers, tended to make less strict self-decisions. In addition, there was also a moderate discrepancy in the gender group. According to the result, compared to females, males were less likely to be affected by peer influences when making self-decision. Therefore, depend on what I found after the analysis, I wrote down the result part and made a discussion in my paper, as well. I also pointed out the function, limitation and how the future study could be.
星期三我会见了教授和TA R，询问统计方法以及如何比较样本组。两个他们是如此善良，给我提供了很好的建议，这使我对下一步有清晰和直截了当的想法。因此，在星期四和星期五，我完成了数据分析（参与者的年龄，大学专业，自我决定问卷的分数）。和同伴影响问卷的SPSS。参加者分为两组：大学专业组商学院、工程学院、文理学院和性别组（男性和女性）。依靠图和各组的相关系数，我发现我的假设是部分对应的。为了说明，有三大群体的中等差异：与文科和理科学院相比，来自学院的年轻人工程和商学院在同伴影响和自我决策的得分上表现出积极的关系这意味着那些与同龄人有相同观点和信仰的人倾向于不那么严格的自我决定。此外，在那里在性别群体中也存在中度差异。根据结果，与女性相比，男性受影响的可能性较小。在做出自我决定时受到同伴的影响。因此，根据我在分析后发现的，我写下了结果部分并做出了在我的论文中也是如此。并指出其功能、局限性以及未来的研究方向。
I submitted my paper draft on Friday night, and I have just talked with my TA R. I got valuable advice from Rachel, and now I’m going to revise some part of my paper today and tomorrow. Also, hope I can also enjoy my life and study here in the next, the final week.
我在星期五晚上提交了我的论文稿，我刚刚和我的助教谈过了。我从助教那里得到了宝贵的建议，现在我今天和明天我要修改我的论文的一部分。同时，希望我也能享受我的生活和学习在这里的下一个，最后一周。
Week 4
During the final week, we continued to talk about an overview of these weeks, as well as the prospect of my project. Professor L suggested that I could amplify the samples in order to enhance the external validity of my paper. His also shared with me his personal experience that studied in various institutions.
在最后一周，我们继续谈论这些周的概况，以及我的项目的前景。L教授建议我可以放大样本，以提高我的论文的外部效度。他也和我分享了他的个人经历。在各个院校学习。
I was going to keep on working my project in further step in the next few months. I hope during the rest time, I could keep on progressing even without Professor L’s immediate help.
我打算在接下来的几个月里继续我的项目。我希望在休息的时候，我可以继续进步。即使没有L教授的直接帮助。
To sum, thanks to this valuable experience! Mr.Z provided me great chance to practice myself in Harvard medical school and Professor L guided me for doing the summer study so nicely. The experience in Boston was so unforgettable. Thanks a lot!
总而言之，感谢这宝贵的经验！Z老师为我提供了在哈佛医学院和教授实习的好机会。我很好地指导了我暑假的学习。在波士顿的经历是如此难忘。谢谢！
