This understanding of emotion has been around since Plato. But what if it is wrong? In How Emotions Are Made, pioneering psychologist and neuroscientist Lisa Feldman Barrett draws on the latest scientific evidence to reveal that our common-sense ideas about emotions are dramatically, even dangerously, out of date - and that we have been paying the price. Emotions aren't universally pre-programmed in our brains and bodies; rather they are psychological experiences that each of us constructs based on our unique personal history, physiology and environment.
