Define the activation-synthesis theory and the information-processing theory. How might you design an experiment to test whether the information-processing theory is correct? What might be the main difficulty with conducting an experiment?

Please consider all questions in the answer, they are connected. Take as much time as needed to process what is asked. There is no need for a complex explanation, just give an exact answer to the given questions, but keep in mind they need to be based on what is asked, not anything lazy. Thank you :)
