Suppose that you are conducting a factorial study with variables A and B. Your results reveal an interaction effect. This means that:
A) Variable A is effective in changing performance only if variable B is also effective
B) The way participants' responses to independent variable A depend on what level of independent variable B they experience
C) One of the variables, A or B, can have an effect on performance only if the other does not
D) The effects of variable A and of variable B cancel each other out
