Transcript of Disgust

Disgust is the feeling of being repulsed by something.

It is one of the six universal human emotions.

At its most basic level disgust stops you from dying.

What makes you disgusted?
Share a few things that have recently disgusted you.

If you can't think of one, lick the person next to you. If you don't feel disgust you will at least get to observe it.
Where does it come from?
Disgust is the last of the universal emotions that children develop.

It is an emotion which we learn, and it develops from distaste.

Distaste is the reaction that happens when you taste something bitter and want to spit it out.
Therapeutically repulsed...
When someone finds something appealing which they shouldn't it can cause problems.

What disgusts us is learned. We learn to be disgusted by things by associating them with other people being disgusted, or with other things which we find disgusting.
Too much of a good thing
In a healthy amount disgust is beneficial to your life, reducing the likelihood of you catching illnesses.

In unhealthy amounts disgust can stop you from living life, causing you to avoid many things which are not harmful and are necessary to participate fully in society.
Fun Facts!
Remember how disgust is a learned emotion? People with obsessive compulsive disorder have a reduced ability to recognize disgust in other people.
Because they essentially feel disgusted all the time they do not learn to associate the face people pull when disgusted with feeling the emotion.
Aversion Therapy
Aversion therapy takes advantage of this.

The patient is exposed repeatedly to their problematic pleasure and a strong, disgusting smell at the same time.

An association between the two should be made, leading to the patient feeling repulsed by the object of their problematic former pleasure.
How does it feel?
Disgust can cause many things including a drop in blood pressure, shuddering, and reduced sweating.

It can trigger nausea, vomiting, and even fainting.

Mental states may vary from mild negativity to overwhelming revulsion.

There is an urge to get rid of or pull away from the object of disgust.
Empathetic vomit...
Disgust is a contagious emotion. If you see someone feel disgusted, chances are you will feel it too.

Food poisoning has been a significant risk throughout human history. In addition people often eat together.

If you saw someone vomit chances were you had just eaten the same thing they did. Those who were inspired to chunder easily survived best.
A physical reaction...
Disgust causes you to pull away.

You recoil from whatever is causing the feeling, pulling away every part of your body possible.

The screwed up face of disgust serves a practical purpose. It ejects what was in your mouth, and reduces what can get in your nose and eyes.
A disgust reaction to taste is instinctive and definative.

This means that you don't need to learn it, and that you don't need to check with any other senses.

If it tastes disgusting it is disgusting.
Visual disgust is not instinctive but it is definitive.

You have to learn what looks disgusting, but you don't need it to be reinforced by other senses.

If it looks disgusting it is disgusting.
Smell and Sound
Reactions to smell and sound are indefinite and subjective.

They need to be learned, and usually need to be verified by another sense to be certain whether something is disgusting or not.
Rational Emotive Behaviour Therapy holds that what causes us to become upset is not circumstances or events themselves, but our beliefs regarding those circumstances.

This holds particularly true for disgust, as it is a learned emotion.
Problematic beliefs
Correct beliefs about things lead to correct responses.
Believing rotten meat is disgusting prevents you from dying.

Incorrect beliefs lead to incorrect responses.
Believing that doors are disgusting will likely cause you problems.
