According to the self-regulation of prejudiced responses model, "internally" motivated individuals may learn to control their prejudices "more" effectively over time.
The Self-Regulation of Prejudice (SRP) model (e.g., Monteith, 1993; Monteith, Ashburn-Nardo, Voils, & Czopp, 2002) describes in what way the process of regulating one's prejudiced responses may be proficient, principally between people who grasp low-prejudice attitudes.
