This research explores the relationship between multiculturalism, diversity, and altruistic behaviors. The researchers hypothesized that individuals with more accepting attitudes toward multiculturalismwould be more comfortable with diversity and manifest more altruistic behavior compared to those with less acceptingattitudes toward multiculturalism. In addition, the researchers also hypothesized that individuals primed with multicultural images would be more likely to be comfortable with diversity and showmore altruistic behavior than those primed with American images. Multiple 2x2 ANOVA tests were utilized to study the effects ofmulticultural attitudes and cultural priming on comfort with diversity and altruistic behavior. No significant main effect of the priming strategies was found; however, attitudes toward multiculturalismdid have a significant effect on all three of the dependent variables, such that participants that scored high on multicultural acceptance were more accepting of diversity and more likely todonate both time and money to a person in need.
