“Yet another problem with the ‘threat response’ theory is that it has difficulty explaining why damage to the amygdala impairs not just people’s ability to respond appropriately to fearful expressions but their ability to even identify them – to come up with a name for what the expresser is feeling. When S.M. sees a fearful face, it isn’t as though she knows what to call it but fails to show appropriate signs of fearful avoidance or vigilance in response. It’s that she sees it and is mystified by its very meaning, like a colour-blind person searching for a number in a featureless array of brown dots.”
