Describe the basic research methods employed in the proactive interference (PI)

Describe the basic research methods employed in the proactive interference (PI) research: the independent variable (IV), dependent variable (DV), experimental groups, and control group. Discuss the outcome of the study and how this supports the hypothesis that failure in recall is not due solely to passage of time (decay theory). Finally, provide a few thoughts about how Piaget’s concept of schema (from Lecture Series 5) factors into participant performance in the PI research.
