What does a psychologist usually mean when she says a particular experimental result is significant?

In science (and possibly in psychology as well), "significant" has a special meaning, which is that two things appear to be correlated more than one would expect from random chance.
If, for example, we have a lot of lab rats, and we play Justin Bieber at half of them and Frank Sinatra at the other half, and all the Bieber rats turn out to be homosexual and none of the Sinatra rats do, that's significant. If we only have a few rats, or if some of the Bieber rats and some of the Sinatra rats are homosexual, then maybe it's significant and maybe it's not; there are mathematical tests you can do to say with varying levels of confidence "Justin Bieber turns rats homosexual."
