Document Summary
Green = people: multifactorial designs has two or more independent variables. Chapter 7: complex research designs: effects of each independent variable on the dependent variable can be isolated and tested, allows the researcher to isolate and test interaction effects of the independent variables on the dependent variable. Multifactorial designs: studies done by paul ekman and other researchers (strack, martin, and stepper, shown that emotions can be covertly induced and reliably manipulated by specific facial muscle contractions. Interaction effects of one level of the independent variable depend on the particular level of the other independent variable: influence of emotional expression differed on whether the eyes of the faces gazed directly or were averted. In a multifactorial experiment that uses a within-subjects allocation, each participant is measured after receiving each level of each of the independent variables: mixed-factorial design has both between-subjects and within-subjects independent variables.
