摘要
According to threat-general perspectives, existentially threatening prospects such as the inevitability of mortality or uncontrollability represent motivational discrepancies that activate the behavioral inhibition system (BIS). The aim of the present paper is to test this claim using neuroimaging and neurophysiological methods. In Study 1, we used neuroimaging to show that both mortality- and uncontrollability-related stimuli elicit activation in the anterior cingulate cortex, which is a key BIS region in humans. Focusing on the idea that BIS activation is associated with increased attention, Study 2 used electroencephalography to demonstrate that both mortality- and uncontrollability-related stimuli enhanced the late positive potential, an indicator of motivated attention. Together, these studies provide support for the model's prediction that existential threat activates the BIS.
