Manipulating Racial Diversity in Group Interaction Studies

My social psychology research lab is interested in the ways in which group composition affects the information processing and cognitive performance of individual group members.  More precisely, we're examining some of the ways in which racial diversity affects individual members of a group.  Right now we're running studies examining how people process information differently depending on whether they're placed in a racially homogeneous or heterogeneous group which is about to interact. 

Running group studies like these is practically difficult and methodologically messy.  Eventually, we'd like to manipulate group composition in a more controlled way, by using a web camera interface to convince participants that they are either part of a homogeneous or heterogeneous group.  In other words, we want to be able to convince individuals that they will be interacting via web camera with either diverse or non-diverse groups to see how these expectations influence them.  Specifically, we'd hope to sit an individual participant at a computer terminal with a web camera.  The participant would then see the web camera images of several other "participants" on the screen, which would actually be prerecorded video.  Everyone in the "group," including the actual participant in our lab, would go around and give a quick hello, but the other "hellos" would be prerecorded.  Then the participant would be given some information to read to prepare for a later group discussion that would never happen.  The webcameras, ideally, would stay on so that if the participant looked up from his/her reading, s/he would see all the other group members also reading their background materials.

In sum, the idea is for us to be able to manipulate an individual participant's perceptions of how diverse his/her group will be through a web camera interface.  At this stage of the research project, the group would not actually interact nor have a conversation.
