This test reveals whether you are introversion or extreme

The amount of saliva you produce after placing several drops of lemon juice in your tongue may reveal how much introversion you are.

In the 1960s, psychologist Hans Eysenck and others argued that introversions produce more spit than extroverts because of natural differences in nerve systems, writes ClassLife.

The main idea was that introverts are characterized by a higher quantum response that increases vigilance, muscle tone, and heart rate.

However, extremists have an initial low point for reaction, and for this reason they need more incentive to get to the same point.

The amount of saliva you produce after placing several drops of lemon juice in your tongue may reveal how much introversion you are.

Why do introverts produce more saliva?

It's about a part of your brain called: Reticular reactivating system (RAS), which responds to incentives such as food or social contact.

For example, you control the amount of saliva you produce in response to food.

The lemon juice provides the perfect feeding incentive to prove it. For many of us, the squeeze of fresh lemon juice in your tongue makes your mouth spit, and that is because your RAS is responding to the coming lemon juice.

Scientists believe that introversions have increased activity in their RAS and have thus increased the production of saliva from lemon evidence. And because RAS also reacts to social contacts, introverts react more strongly even when they meet people. By contrast, extrevers demand a much greater incentive to generate an answer. So they usually produce less saliva in response to lemon juice than introversion, but they're more comfortable in social groups.

Take your own test

Try this simple test with friends and family and compare your results.

Keep half of a lemon in your tongue for about 20 seconds. Then without swallowing it, shut up for two seconds. What do you see? Too much spit? Or the usual amount?

Compare Yourself to a Friend

Use cotton balls to erase all the saliva you produce. When you have all cleaned up, put the cotton ball on the scales of your kitchen to measure your weight.

Compare your results with your friends and family and see who weighs more. Introverts produce many salivas in response to lemon juice compared to that produced by extreverts.
