All my friends really want a smart phone. A heavy wind of smart phone is everywhere. It is all over the world. When I surf the internet, articles of the smartphone are everywhere. People want to know which one is good, or they write about private experiences. Some people said, “I am an iphone user, this is good and I want to share my experiences with other people”, and they explain details about using the smartphone.
A smartphone’s definition is “a mobile phone that offers more advanced computing ability and connectivity than a contemporary basic feature phone (Wikipedia)”. Smartphones, such as Apple's iPhone is the most well known smartphone until now, and other mobile phones with computer-like capabilities, are rapidly becoming not only commonplace on college campuses but also everywhere. When I watched television, I see many mobile phone commercials; especially the smart phone.
I am from South Korea. Last summer vacation I went back to South Korea. I met my friends, they were using smartphones. Many of my friends were waiting for the iphone 4. It was offered in June in the United States, but South Korea could not decide which month to offer the iphone. So many people made a reservation for the iphone at the time. Also, when I bought my smartphone, I waited over one month in the United States. Smartphone had many commercials in South Korea. In the commercials the actors are the most famous and trendy movie stars or singers. So when we are watching smartphone commercials, we can be known for the most famous stars of the year in South Korea.
Do you think why the smartphones is so rapidly popular? All my friends have a smartphone in the United States and also in South Korea. My country developed the IT industries that make smartphones, like Samsung and LG. The smartphone provides a lot of uses from the internet. There are students using their smartphones for their homework and research papers. I am an art student. I am taking a painting class. I have to show my professor some images. I did not bring my heavy lap top. I have just a smartphone. During art, students are usually working on their works; they are listening to music in class. However, we have no more MP3 players, or ipods. Smartphones are used in the classroom primarily for music. I can download music from the internet on my smartphone.
I am an international student. Almost every international Korean student brings some electronic device in their school. It looks like a little lap top. It is an electronic dictionary. Students who English as a second language usually bring it to not only school but also everywhere. I usually bring my electronic dictionary even when I meet American friends. While I am talking with my American friend, I am sometimes confused and do not understand what they are saying. I find some words and word pronunciations in my dictionary. Now I have a smartphone. When I meet American friends, I am not bringing electronic dictionary anymore. When I drive to unfamiliar places in Dallas, sometimes get lost road. When I first drove in Dallas, many places looked so similar. If I looked for some building and it near Mac Donald’s, Best Buy, and Wall Mart in every place, my feelings were every place looked the same. I did not have a GPS. I felt uneasy, and nervous. But now I have a comfortable feeling while I am driving, and more familiar American roads, and a smartphone has a capacity of GPS. I used the Wi-Fi internet, but it often times is disconnected. I have to pay my bill payment, but my bank is so far from my apartment. I pay my bills by my smartphone. I check my email while waiting in line at the coffee the shop. I read while sitting on the couch without a paper book.
Since the dawn of the smartphone I multitask. Some scientists said the human mind multitasking capabilities are not simply working. That means people while watching some TV program, cannot read email. Because people are trying so hard to listen to two conversations at the same time. Scientists say the human brain is lacking when they suddenly switch between tasks. Since each time you rapidly switch, you break your focus. When you’re attention is divided, your works suffers. When I had free time, I could not put down my smartphone. Many people have those kinds of experiences. We all know that it is tough to put down your smartphone like me. Sometimes even for just a few minutes. When I go to sleep in bed, I usually read some articles, web surf, or go to my Korean Facebook by my smartphone. I think to myself, I have to sleep, I have to wake up early, but I still keep going and going. My smartphone might be more like an addiction. When you are using a smartphone each notification, ring or buzz, your brain squirts out dopamine. “It is a natural dopamine, a natural neurotransmitter released by your brain which activates your pleasure receptors. The substances in drugs that make us feel good work by the very same mechanism (never.com).” The scientists conjecture, when you are using smartphones, you get a tiny shot of dopamine. If you do not get it, you are anxious, and enervate. That is why often times you use and check your phone are. Your brain gets addicted to dopamine. If you’re behaviors like that, you are addicted to your smartphone.
Have you heard of “The Three Day Effect”? “It is a phenomenon observed by some neuroscientists who purposely sequestered themselves from digital media for a week, which meant no cell phones, no Internet and no TV (serendip.brynmawr.edu).” Some people about three days after no interfacing with computers, smartphones, video games, or some other kinds of technology, can feel more relaxed. They did not feel an anxious, and enervate, they can sleep better. My major was industrial design in Korea. I spent most of the time with a computer. I had such a headache; I did not want to use my computer anymore, so I changed majors in the United States. Now, I study drawing and painting. Some scientists state that being disconnected from technology even helps you are more creative.
The indication that smartphone in other studies state that you have to be stressed at all times with continual updates, ringing and notifications. You might be receiving a lot of email that would demand some your attention. So you are checking your smartphone again and again. However, you do not know when you will receive your next email, Facebook or twitter. The stress brings some hormones into your body, such as cortisol. It is an important hormone in the body, It’s Higher and more prolonged level of cortisol in the bloodstream have been shown to have negative effects, such as: Decreased bone density, Decrease in muscle tissue, and Higher blood pressure. “It is the most potent glucocorticoid produced by the human adrenal. It is synthesized from cholesterol and its production is stimulated by pituitary adrenocorticotropic hormone which is regulated by corticotropin releasing factor (aeron.com).” It affects to human body. A lot of stress hormones, such as cortisol, can affect your long term memory. This means if you use your phone a lot, your brain’s memory abilities less you cannot remember.
There are many negative effects of smartphone. Despite many people wanting smart phone. Not just young people but also old people all over the world. It has become trendy for all ages and classes to have the latest technology. It's convenient; they can use internet without a big computer everywhere. People want to get good stuff, such as a nice car, good clothes, and expensive houses. When someone has a trendy new smartphone, it feels like you are wearing designer clothes. Smartphones are going to change history, such as computer or internet did.
