People who appear to view the world through rose-tinted glasses respond more positively to happy images, research has found

Psychologists discovered that some people's brains were attuned to react to nice pictures – while others failed to react. Academics analysed the reaction in the amygdala - the part of the brain which processes images and our emotions. While all people reacted in the same way to negative images, the happiest people were most likely to react to positive images. This effect is believed to reinforce itself over time – giving some people a rosy outlook outlook. The study showed that it is not because of ignorance that people respond in a positive way – but a chemical reaction in the brain. Hat tip, hbd* chick!
