Think of a study that might test each of the following hypotheses. For each, indicate whether you think the independent variable should be a between or within the subjects variable or weather each approach would be reasonable. Explain your decision in each case. 1.

A clinical psychologist thinks that phobias can be cured by repeatedly exposing the person to the feared object and not allowing the person to escape until the person realizes the object is really harmless.
