A multi-group design is an experimental design that has 3 or more conditions/groups of the same independent variable. This video demonstrates a multi-group experiment that examines how different interethnic ideologies (multiculturalism and color-blind) influence feelings about diversity and actions toward and out-group member. In providing an overview of how a researcher conducts a multi-group experiment, this video shows viewers how to distinguish levels in variables, common types of conditions/groups to use (including placebo and empty-control conditions/groups), the process of conducting the study, the collection of results, and the consideration of their implications.

Social ostracism is defined as being ignored and excluded in the presence of others. This experience is a pervasive and powerful social phenomenon, observed in both animals and humans, throughout all stages of human development, and across all manner of dyadic relationships, cultures, and social groups and institutions. Some have argued that ostracism serves a social regulatory function, which can enhance group cohesion and fitness by removing unwanted elements.1 As such, the feeling of ostracism can serve as a warning to alter one’s behavior, in order to rejoin with the group.2 Research in social psychology has focused extensively on the affective and behavioral consequences of social ostracism. For example, individuals who have been ostracized report feeling depressed, lonely, anxious, frustrated, and helpless,3 and while they may now evaluate the source of their ostracism more negatively, they will also often try to ingratiate themselves to them.2 Furthermore, it has been speculated that the fear of ostracism is ultimately driven by a strong need to belong and to feel included, and serves as a social pressure leading to conformity, compliance, and impression ma
