Two studies investigated whether children's television programs that were produced to decrease racial prejudice had the intended positive effect on young children. Study 1 measured 60 White 5- and 6-year-old children's attitudes toward Asian, Black, and White stimuli prior to, and immediately following, a brief, one-time anti-prejudice television program. No significant change was observed. Study 2 assessed the attitudes of 30 White 3-6-year-old children toward Asian, Black, Hispanic, and White stimuli at the beginning and end of a 3-week intervention period. During the intervention period children watched a pro-diversity television program four times. Plot and anti-prejudice message comprehension was assessed at three time-points during the testing period. Participants improved on plot and message comprehension over time, but no change in ideas about race was evidenced (children indicated a strong pro-White bias at both pre- and post-test). Possible reasons for, and implications of, this lack of change are discussed.
