The experimental model used human participants, typically split into groups and exposed to different experiences, to gauge the effect of independent variables. Much of the research was conducted at colleges and universities and for a very long time the participant pool consisted almost exclusively of white males. In an integrated format, discuss advantages and disadvantages of using this restricted participant pool. Be sure to support your opinion with specific examples and reference issues related to validity and reliability, as well as ethical concerns.
