Scientists claim to have discovered why some people like to spend their nights at wild parties while others prefer to stay in with a cup of tea.



The brains of introverts and extroverts differ in the way they respond to experiences, according to a new study.



The research revealed that extroverts like instant gratification while introverts tend to be distressed by excessive stimulation.

People who are extroverts tend to focus their attention on people’s faces while those who are more introverted tend to pay more attention to smaller details - which could explain why they do not like overly stimulating situations.



Live Science reported that Yu Fu and Richard Depue at Cornell University, in New York, U.S., studied a group of students to find a mixture of introverts and extroverts.



They then gave the volunteers Ritalin, a drug used to treat ADHD, which encourages the brain to produce the feel-good chemical dopamine.

The volunteers were then asked to watch a video while the researchers studied how the footage was linked to dopamine release in their brains.



They did this by studying the behaviour of the participants, including their demeanour and how quickly they could tap their fingers. .

This revealed that extroverts experience rushes of dopamine as a result of their environment while introverts do not

As a result, the researchers concluded that introverts have fundamental differences in the way their brains work.



‘The findings help link the personality trait of extraversion to a particular set of processes in the nervous system,’ psychologist Charles Carver told Live Science.
