The reverse inference problem: affirming the consequent fallacy -> showing that a causes b doesn"t mean that if b is present, If asked to rate faces on which look friendliest or most trustworthy, rate almost all equal: when soldiers in vietnam war suffered wounds causing brain damage that didn"t include amygdala, 40% got ptsd. If damage did include amygdala, none got ptsd suggesting activation in amygdala may be related to anxiety in some way. Interoception: perception of body itself, especially its interior organs i. e. heart, digestive system, bladder, muscles, skin: people with damage to insula report weaker than average emotional feelings and report feeling less empathy when seeing other people in distress.
