T-Shirt

Brain activity tracks the preferences of others.

A new study published by Izuma and Adolphs in Neuron asks what are the brain areas that undergo changes in activity when we modify our preferences to fit social context1.

In other cases I tell them that it is the preferred shirt of most criminals. What we get is a socially-manipulated preference – people tend to dislike the criminal’s favorite. Continue reading
