Brain process involving decision making
Usually People uses system 1 to decide. They will try to decide which option will give best values, based on information gatherd in the dlPFC[1], and calculated by the vmPFC[2]. Dolan also found that the PFC also connected to conflict solving.
When people scurtenise the world, they are compering the phenomena to information they gatherd in their NMOs. A contrediction is detected by the ACC, which activate system 2 in order to solve the contrediction. system 2 will oprate also when a novel task or complext rational task will presnt themselves.
When in stress, the FFFF system is put action. It seems that it inhibit ACC activation, thus, closing the actvation of system 2, and probably closing also jeneral empathy. The FFFF system may open a process to strength "famely" relations to strength group cohesion.
Other subjects of decision making
Mere-exposure effect - people will prefer objects they were more exposed to, but to a some degree. If the object was disliked in the first place, it will be more disliked. The effect is limited in duration, after 20 exposures, the effect diminish. When people were presnted with comercial to a drink with happy faces in mere exposer effect, they preferd it, over the same drink, without smiling object. This strenght the concept that people may decide in acordance to their feelings and not on a rational base.
