文摘

We test the Somatic Marker Hypothesis using a novel “Lose Iowa Gambling Task”. The Lose version reverses the predictions about the development of somatic markers. People learn in both IGTs but the pattern of preferences does not simply reverse. Higher skin conductance for outcomes not conducive with current goal in “Lose IGT”. Support for the pivotal claim skin conductance guides decision making was not found.
