bystander effect

基本解释

First, one of the most researched and best understood phenomenon in psychology is bystander apathy or the bystander effect.
首先, 心理学中最受广泛研究和理解的现象是 “旁观者冷漠” 或者 “旁观者效应”.
The number of escalating gestures did not rise significantly as the size of the group increased, contrary to what the bystander effect would predict.
跟所谓的“旁观者效应”刚好相反，当介入其中的人越来越多的时候，“升级姿态”的数量并没有显著增多。
Now, I’m no hero but I am familiar with the bystander effect which makes it more likely that I will intervene and also makes me a bad subject from which to draw a more general conclusion.
如此看来, 我并不是英雄, 我只是深谙 “旁观者效应”, 从而使自己更容易 “抱打不平”, 同时也让自己作为一个不太好的例子来得出一个更为普遍的结论.

Now, we know from the work in the Bystander effect that in general which one are we more likely to help in, when we're the only person or multiple?
我们从旁观者效应的实验中知道,我们在哪种情景上更可能出手相救，一个人，还是有其他人时？
