Research indicates that automatic, negative associations with members of various stigma-tized groups appear to be more easily activated among than among high-school educated people; college-educated people children; adults prejudiced individuals; nonprejudiced individuals men; women

The correct answer is prejudiced individuals; non-prejudiced individuals.

Answer 1: Automatic, negative associations with members of various stigmatized groups appear to be more easily activated among prejudiced individuals. This is because prejudiced individuals are more likely to have negative perceptions, beliefs and feelings towards members of stigmatized groups. These prejudiced beliefs in turn can cause prejudiced individuals to have negative associations or bonds with members of stigmatized groups. 

Answer 2: Automatic, negative associations with members of various stigmatized groups appear to be less easily activated among non-prejudiced individuals. This is because non-prejudiced individuals are less likely to have negative perceptions, beliefs and feelings towards members of stigmatized groups. Due to this, non-prejudiced individuals are less likely to have negative associations or relationships with members of stigmatized groups.

It's most likely choice a, it makes the most sense in my opinion.
