Have you ever thought about how much your actions relate to what your gut is telling you to do? Well until I read chapter 11 about emotion I hadn't thought about it either. There is a theory known as "somatic marker theory" which is a theory proposing that we use our "gut reactions" to help us determine how we should act. When your nervous for something, such as when your on a date with someone and you start to sweat and your heart rate goes up, apparently that means its a signal to help you determine what to do next. Such as asking the person out on another date. The somatic marker theory help us make decisions, but aren't necessary for wise choices.
