# Continuity correction for Pearson and McNemar's chi-square test

I think this is a rather basic question, but I just realize that I don't quite understand the term continuity correction.

I use R and found the same syntax correct=TRUE for both chisq.test and mcnemar.test. Are they referring to different continuity correction method?

I have heard of the yate's continuity for pearson chi-square test is not very popular now as it may "over-adjust" the result, then how about that for McNemar's chi-square test?

Thanks.
