Various researchers have undertaken efforts to examine the psychological effects of Internet use. Some research employs studying brain functions in Internet users. Some studies assert that these changes are harmful, while others argue that asserted changes are beneficial. ==Assertions== American writer Nicholas Carr asserts that Internet use reduces the deep thinking that leads to true creativity. He also says that hyperlinks and overstimulation means that the brain must give most of its attention to short-term decisions. Carr also states that the vast availability of information on the World Wide Web overwhelms the brain and hurts long-term memory. He says that the availability of stimuli leads to a very large cognitive load, which makes it difficult to remember anything. Computer scientist Ramesh Sitaraman has asserted that Internet users are impatient and are likely to get more impatient with time. In a large-scale research study〔 that completed in 2012 involving millions of users watching videos on the Internet, Krishnan and Sitaraman show that users start to abandon online videos if they do not start playing within two seconds. In addition, users with faster Internet connections (such as FTTH) showed less patience and abandoned videos at a faster rate than users with slower Internet connections. Many commentators have since argued that these results provide a glimpse into the future: as Internet services become faster and provide more instant gratification, people become less patient〔(The Patience Deficit ), by Nicholas Carr, Dec 2013.〕 and less able to delay gratification and work towards longer-term rewards. Psychologist Steven Pinker, however, argues that people have control over what they do, and that research and reasoning never came naturally to people. He says that "experience does not revamp the basic information-processing capacities of the brain" and asserts that the Internet is actually making people smarter. Psychologist Andre De Castro from York College NY says that social networks are the true downfall for people who use the Internet. In his research paper he describes how social networks allow people to draw on their "mirror image." This causes a disturbing psychological effect, which can confuse people on their true identities. De Castro also discusses how time-consuming social networks can become for the common student. He also discusses the anxiety that constantly checking your phone can bring to the average human, and suggests that social networks are more addictive than drugs and can have a severe psychological impact in the long run of constant Internet use. He believes people go through phases and being a social network junkie is a common phase people eventually will find themselves out of. He states "It can take years to break through the social network addiction." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Psychological effects of Internet use」の詳細全文を読む スポンサード リンク
