Performing deliberate acts of kindness makes pre-teen children more popular with their peers, say scientists.

A new study shows that the popular kids in high school wind up making more money. Then again, a lot of people still hate them

"Reductionism!" is a charge often flung at geneticists, from accusers in the popular press and also, not infrequently, from many fellow scientists. What is it that leads so many people to so fundamentally misunderstand what genetics is about?

Salamone, a UConn Board of Trustees Distinguished Professor, has spent most of his career battling a particular long-held scientific idea: the popular notion that high levels of brain dopamine are related to experiences of pleasure. As increasing numbers of studies show, he says, the famous neurotransmitter is not responsible for pleasure, but has to do with motivation.

Prior research has documented cultural dimensions that broadly characterize between-culture variations in Western and East Asian societies and that bicultural individuals can flexibly change their behaviors in response to different cultural contexts. In this article, we studied cultural differences and behavioral switching in the context of the fast emerging, naturally occurring online social networking, using both self-report measures and content analyses of online activities on two highly popular platforms, Facebook and Renren (the "Facebook of China"). Results showed that while Renren and Facebook are two technically similar platforms, the Renren culture is perceived as more collectivistic than the Facebook culture. Furthermore, we presented evidence for the first time that users who are members of both online cultures flexibly switch and adapt their in-group sharing behaviors in response to the online community in which they are: They perform more benevolent in-group sharing when they participate in the Renren community and less so when they participate in the Facebook community. We discussed both the theoretical and methodological implications of the current research

Psychology is a relatively new science which gained popularity in the early 20th century with Wilhelm Wundt. In the zeal to learn about the human thought process and behavior, many early psychiatrists went too far with their experimentations, leading to stringent ethics codes and standards. Though these are highly unethical experiments, it should be mentioned that they did pave the way to induct our current ethical standards of experiments, and that should be seen as a positive
