Transcript of Carney Landis Facial Expression Experiment

Carney Landis Facial Expression Experiment

Basic Information...
Results
The conclusion enforced that subjects would be willing to act upon something without question. Only 1/3 of the subjects refused to behead the rat but the other 2/3 did it even though they might have been disgusted.
The Rat
This experiment was unethical due to the fact that when students were asked to decapitate a rat most did not know how to perform the act in a humane matter. Also, if subjects refused they were forced to watch the inhumane act done right in front of them by Landis himself.

Information
In 1924, Carney Landis, a psychology graduate at the University of Minnesota developed an experiment to determine whether different emotions create facial expressions specific to that emotion. The aim of this experiment was to see if all people have a common expression when feeling disgust, shock, joy, and so on.

Other Information
As you could see in some of those pictures there were lines on the subjects' faces. This was an example of the black lines that Landis drew on their faces when conducting the experiment to see if all emotions were known as an universal expression. To help him draw these lines he used a basic ruler and marker to make sure the lines were definite.
How did it work?
Landis started by taking a willing participant and began drawing black lines on their face to mark where all their muscles were that helped to show the muscle movement in the persons face when reacting.
The Stimuli
Carney Landis made subjects smell ammonia, watch pornography, and place their hands into buckets of frogs. Then were asked to behead a rat. (the subjects were not aware the rat beheading)
Hypothesis
if faced with different situations to provoke different facial expressions, then the observer will be able to recognize universal facial expressions.
Subjects
Most subjects were graduate students from the University of Minnesota
Independent Variable
The stimuli used on the subjects.
Dependent Variable
Whether or not the subjects reacted to the stimuli. (the facial expressions)
Control Group
Landis did not have a clear control group, it seemed as if he experimented on all of the subjects.
Experimental Group
The graduate students from the University of Minnesota
Unethical
Did not respect the dignity of the subjects
Did not inform the subjects of all the events that may have occurred
Did not respect the rights of animals and did not do the act in a humane manner
Did not check in with subjects to see if they were emotionally stable
Did not inform the subjects that they would be able to leave the study if they felt uncomfortable
Improvements?
Instead of using the physical to see how they would react use prompts to get a reaction from the subject.

Climax of the Experiment
At the climax of the experiment, Landis wanted the subject to then decapitate a rat. If the subject refused he would force them to watch him while he did it himself.
Conclusion
Landis's experiment showed a stunning display of willingness many people had to obey the demands of experimenters and higher placed individuals, no matter how bizarre and strange those demands might be.
