Carney Landis’s Traumatic ‘Facial Expressions’ Experiment

We look at the ‘universal facial expressions’ experiment, which was carried out in the 1900s, when the concept of ethics was not discussed in experiments as much as it is today, and which left psychological traces on participants that are hard to erase.

From the past to the present, there are countless tryIt is debated within which frameworks it can be considered ethical or not. When we look at the reasons for these discussions, we look at the animals and humans in the experiments. unethical The issue of whether or not they are treated in this way draws attention.

We have seen many experiments in which these very sensitive issues were ignored. But 1924 in the year Carney Landis The experiment at the center of our content, by .

Briefly, what was this experiment?

Psychologist born in 1897 Carney Landisa specific reaction elicited by each emotion in the ‘Universal Facial Expressions’ experiment, namely face expression He wanted to know if

If all subjects are happy the same common facial expression If he had, this experiment would have succeeded. The same fearIt also applies to different situations such as surprise.

Landis, who was a graduate student at the University of Minnesota at the time of the experiment, included 25 people in the experiment.

Of these, 12 are male, 12 are female, and the remaining 1 is under the supervision of the University of Minnesota psychology department. 13 year old was a child.

In the first phase of the experiment, which will become chaotic, lines were drawn on the faces of the participants.

Some of the participants

certain facial expressions over the muscles These coinciding lines would make it easier to monitor the reactions to be given.

And the first phase of the experiment began

At this stage, the participants performed actions that would reveal the desired emotion. Ammonia Smelling is an example of this. Other than that it’s like lying simple There are things too. Stimuli like this were used in the first phase of the experiment.

While performing these actions, participants photos and their reactions were recorded.

We would like to say the experiment is over here, but the results did not satisfy Landis.

Therefore, the second phase of the experiment was started. Here, the subjects pornographic images are displayed. The part that spoils the taste here is that the participants had previously informed not having been.

When that’s not enough in their skin Photos of people with problems were shown to the participants. without any censorship and the vast majority uncomfortable These images, which will be

The participants, who did not understand where he had fallen, were shocked when Landis detonated a gun in the same room:

Landis also did this to people, when they are shocked He aimed to see if they had a common facial expression.

The effect of these successive events on the participants has already been felt by this point. permanent has even happened. It is clear that being a psychologist in the 20th century brings great freedom. But to be a tester is probably in these times the last thing to ask for.

Do you think it’s over? Unfortunately no

At another stage, Landis blindfolds the participants and puts their hands together. into the bucket He wants them to dive. In this hive there are many live frog exists.

The goal is to find what is hidden inside the box. Meanwhile, of course disgust reaction of the situation is observed.

Stop now…

Inside the hive—out of the frogs— cables Participants who found that these wires experienced a significant, if not severe, pain from these wires. with electric current faced.

We came to the darkest part

Still not satisfied with the results Landisgave the participants a knife in one hand and a live mouse in the other hand and shook the mouse’s head. cut them off wanted.

At this point, of course, the interrogations flared up even more. Already up to this point, Landis, who had received countless curses and different reactions from the participants, took the knife and mouse from their hands when he realized that they would not do this. he did it himself.

Participants 2 out of 3 He had carried out this order. The rest had to watch Landis do it.

What results do you think you had after this experiment, which did not leave mental health in the participants?

to the fact that there are no fixed and common facial expressions elicited by certain emotions. If only We say that it had not been reached in this way. With this experiment, it is underlined that certain facial expressions do not directly represent emotions when viewed backwards. drawn.

Someone who is into frogs might love to touch them. Likewise, pornographic images (although their sudden appearance may surprise people) will disturb such a No rules.

So all the torture suffered by the participants, just ‘it wasn’t like that‘ was to say

Child participant

And those who are already facing certain psychological problems 13 year old The child has also passed through these stages.

As a result, both the mental health of the users were disregarded and unethical animals were treated. Landis is remembered for this gruesome experiment, although he was later mentioned in different and important studies that did not involve any rodent.

There is an important point that the experiment indirectly proves.
