Introverts and extroverts have very different personalities. According to a new study they also have different ways to process rewarding experiences. The new study was published in the Frontiers in Human Neuroscience journal. It showed that extroverts are more likely to connect feeling good with where they are at the time of having the feeling.
There are so many differences between introverts and extroverts, but how their brains process things is still an area of study that requires much more research. Researchers have found that extroverts want instant gratification and rewards while introverts tend to be overwhelmed when they are presented with too much stimulation at one time. Introverts tend to pay more attention to details as well while extroverts are drawn to the face value.
To test and study the difference between the two, Yu Fu and Richard Depue from Cornell University took a random sample of 70 people who had taken a personality test upon entering the college. They took samples of introverts and extroverts. Some of the participants of the study were given Ritalin, which is a medication for ADHD. They were then put into a room and watched videos in a lab.
After the videos were over they were tested to see how strong of a connection the participants made between the videos and the dopamine rush that was created by the Ritalin. They tested their speed at finger tapping, subconscious traits, and working memories to help aid the researchers in finding answers. What they found is that the extroverts strongly associated the videos with the rush they were feeling while the introverts showed little or no association.
The findings of this study were that introverts are more likely to respond to internal stimuli when thinking about rewards as opposed to outside rewards that are given to them.
