| Previous research has suggested a link between violence and
game playing. |
Violent computer games may make people more likely to act aggressively,
a study says.
Previous research has found people who play such games are more likely
to be aggressive but some say this just shows violent people gravitate towards them.
But a team from the University of Missouri-Columbia said their study
which monitored the brain activity of 39 game players suggests a causal
link.
The findings were published on the New Scientist website.
The researchers measured a type of brain activity called the P300
response which reflects the emotional impact of an image.
When shown images of real-life violence, people who played violent
video games were found to have a diminished response.
However, when the same group were shown other disturbing images such as
dead animals or ill children they had a much more natural response.
When the game players were given the opportunity to punish a pretend
opponent those with the greatest reduction in P300 meted out the severest punishments.
Psychologist Bruce Bartholow, the lead researcher of the study which
will be published in full in the Journal of Experimental Social Psychology
later this year, said: "As far as I'm aware, this is the first study to
show that exposure to violent games has effects on the brain that predict
aggressive behaviour.
"People who play a lot of violent video games didn't see them as much
different from neutral.
"They become desensitised. However, their responses are still normal
for the non-violent negative scenes."
The findings will back up what many have argued over recent years with
the growth in games with scenes of graphic violence.

研究表明，玩暴力電腦游戲會(huì)讓人變的更具侵略性。
此前的調(diào)查發(fā)現(xiàn)愛(ài)玩暴力游戲的人侵略性較強(qiáng)，但是有人說(shuō)這只能說(shuō)明具有暴力傾向的人喜歡玩暴力游戲。
密蘇里哥倫比亞大學(xué)的一個(gè)研究小組說(shuō)，他們對(duì)39個(gè)游戲"玩家"的腦部運(yùn)動(dòng)進(jìn)行了監(jiān)控，結(jié)果發(fā)現(xiàn)玩暴力游戲確實(shí)會(huì)導(dǎo)致暴力傾向。
這個(gè)研究結(jié)果公布在《新科學(xué)家》雜志的網(wǎng)頁(yè)上。
研究人員對(duì)一種名為"P300反應(yīng)"的腦部活動(dòng)進(jìn)行了測(cè)量，"P300反應(yīng)"體現(xiàn)了圖像對(duì)人情緒的影響。
當(dāng)把現(xiàn)實(shí)中的暴力畫(huà)面放在暴力游戲玩家面前時(shí)，他們的反應(yīng)不是很強(qiáng)烈。
然而，當(dāng)看到其它的消極畫(huà)面時(shí)，比如，死去的動(dòng)物或生病的孩子，他們的反應(yīng)則比較正常。
但是，當(dāng)一個(gè)虛擬對(duì)手出現(xiàn)，游戲玩家得到懲罰對(duì)手的機(jī)會(huì)時(shí)，P300反應(yīng)最弱的玩家給予了對(duì)手最嚴(yán)厲的懲罰。
這項(xiàng)研究的領(lǐng)頭人心理學(xué)家布魯斯·巴索洛說(shuō)："據(jù)我了解，這項(xiàng)研究首次揭示玩暴力游戲會(huì)對(duì)預(yù)知進(jìn)攻行為的腦部組織產(chǎn)生影響。"研究報(bào)告全文將于今年晚些時(shí)候在《實(shí)驗(yàn)社會(huì)心理學(xué)》雜志上發(fā)表。
"愛(ài)玩視頻暴力游戲的人并不覺(jué)得自己跟其他人有什么不一樣。他們的感覺(jué)變得遲鈍。但是在看到非暴力的消極場(chǎng)景時(shí)，他們的反映還是正常的。"
近年來(lái)，帶有暴力場(chǎng)景的電腦游戲不斷增多，很多人對(duì)此提出異議，而此項(xiàng)研究結(jié)果則將成為這些人的有力支持。
P300是一個(gè)跟獨(dú)特訊息有關(guān)的波形（即在刺激畫(huà)面呈現(xiàn)之后300毫秒時(shí)，大腦所出現(xiàn)的一個(gè)正波。
