sentimentality

I need an explanation for this Sociology question to help me study.

First, define both types of sentimentality. Next, name and discuss a situation where a researcher would need to invoke conventional sentimentality AND a situation where a researcher would need to invoke unconventional sentimentality

answer it with couple of sentences.
