When preschoolers spend time around one another, they tend to take on each others' personalities, indicates a new study by Michigan State University psychology researchers.

The study, published online in the Journal of Personality and Social Psychology, suggests personality is shaped by environment and not just genes.

"Our finding, that personality traits are 'contagious' among children, flies in the face of common assumptions that personality is ingrained and can't be changed," said Jennifer Watling Neal, associate professor of psychology and co-investigator on the study. "This is important because some personality traits can help children succeed in life, while others can hold them back."

The researchers studied two preschool classes for an entire school year, analyzing personality traits and social networks for one class of 3-year-olds and one class of 4-year-olds.

Children whose play partners were extroverted or hard-working became similar to these peers over time. Children whose play partners were overanxious and easily frustrated, however, did not take on these particular traits. The study is the first to examine these in young over time.

Emily Durbin, study co-investigator and associate professor of , said kids are having a bigger effect on each other than people may realize.

"Parents spend a lot of their time trying to teach their child to be patient, to be a good listener, not to be impulsive," Durbin said. "But this wasn't their parents or their teachers affecting them - it was their friends. It turns out that 3- and 4-year-olds are being change agents."

MSU doctoral students Allison Gornik and Sharon Lo co-authored the study.

There is no such thing as a "personality"...

BubbaNicholson

That's a strange assertion.
Isn't it an empirical fact that different people seem to have different personalities?
It is surely extremely difficult to deny and not notice the obvious difference between a violent angry load-mouthed anti-social psychopath and a calm gentle loving person. What would you call that kind if difference if not a "personality" difference? That is after all generally the kind of thing we mean by the word "personality".

Use Occam's razor to elucidate, not untestable...

One test for the most extreme form of psychopath personality would be how many people he murders.
OF COURSE personality is testable!
