Question Answered step-by-step In 1924, University of Minnesota psychologist Carney Landis began… In 1924, University of Minnesota psychologist Carney Landis began an experiment to study common facial expressions. Specifically, he wanted to know if everyone’s expressions of happiness, shock, disgust, etc. appeared the same. To conduct his experiment, Landis recruited a number of student volunteers, then painted the lines of their facial muscles black. He then exposed each participant to various stimuli in order to photograph their reactions. Some such stimuli included pornography, ammonia, touching reptiles, and physically beheading rats. One-third of the participants willingly beheaded the rat when told, despite the fact they did not know how to do such a thing humanely. For those who hesitated upon the direction to kill the rat, Landis decapitated the animal for them. Is this study unethical?  Why or why not?  What could the researchers have done differently?                  Social Science Psychology PSYC 230 Share QuestionEmailCopy link Comments (0)
