Compare and contrast convergence theory and contagion theory.

Convergence theory argues that the group is not the source of negative,irrational behaviour.Instead,negative,irrational behaviour is located in the person.Contagion theory applies social psychological principles to understand why people behave differently when they are in groups than when they are alone.Convergence theory does not view people as passive beings who cannot control themselves,as contagion theory suggests.Rather,convergence theory asserts that the actions of the group are an expression of its members' own desires for types of behaviours they are willing to seek out.
