Disclosing information about the self is intrinsically rewarding
Studies 1a and 1b, fMRI, n = 78 and n = 117, NAcc self > other, d = 0.41 and d = 0.35; Study 2, n = 37, 195 trials, payoffs of $0.01 to $0.04, 0.63 cents per trial forgone against other-judgement, average loss of 17 per cent of potential earnings; Study 3, fMRI, n = 17; Study 4, n = 41, 240 trials against a 5-s passive delay, answers shared with a friend on shared trials, average loss of about 25 per cent of potential earnings on self shared trials, self-disclosure valued at 0.97 cents.
