Document Summary
Research dilemma - want high ext and int validities. Due to inverse relationship, cannot have both be high. For some experiments, threats to ext validity are more severe than threats to int validity. E. g. , you want your results on video game violence to be generalizable. = creation of experimental conditions that simulate the natural environment being examined. E. g. , car and flight simulators simulate what it"s like to be operating the vehicle. E. g. , virtual reality closest simulation of visual environments. Mundane - superficial simulation of environment that you are studying. Experimental - tries to immerse participants in the simulation so they start to act naturally. Was so realistic that the experiment had to be stopped early due to the psychological trauma experienced by the prisoners". E. g. , used to study racism, gender stereotyping, employee conflict/cooperation. Experiment is conducted in a setting that is participant perceives as natural.
