Slowing when deciding for others predicts hyperaltruistic valuation of pain. (A) Deciders were slower to decide when choices affected others, relative to when choices affected themselves. Error bars represent the SEM. *P < 0.05. (B) The degree of slowing when deciding the fate of others (relative to oneself) predicted the degree of hyperaltruism, (r = 0.419, P = 0.006).
