According to research on prejudice and self-regulation, which of the following people would likely perform the WORST on a self-regulation task?

A) Al, a highly prejudiced white man who has just been talking with a group of black people
B) Juan, a highly prejudiced Mexican who has just been talking with other Mexicans
C) Richard, a fairly unprejudiced Asian man who has just been talking with a group of Latinos
D) Pierre, a fairly unprejudiced white man who has just been talking with other whites

Research on prejudice and self-regulation suggests that individuals who are highly prejudiced may need to exert more self-control to regulate their behavior and attitudes in socially diverse settings. Al, being highly prejudiced and having just interacted with a group of black people, would likely have expended more cognitive resources to regulate his prejudiced responses, leaving him with fewer resources for subsequent self-regulation tasks, thus performing the worst among the options given.
