Encoding of selection by client and client selection switch. a During the observation of evidence stage, activity in right TPJ (coordinates: [51,−58,35]) was higher on ignored vs. chosen trials (P < 0.001, FWE cluster size-corrected P < 0.05). b Analysis of beta estimates from the right TPJ showed a significant selection by client effect (N = 32, F(1,94) = 11.4, P = 0.002). Error bars indicate 2 SEM. c Client selection effect on activity in the right TPJ was correlated with the participants’ fear of negative evaluation (FNE) score: differences in rTPJ activity between ignored and chosen trials was greater for participants with high FNE score (N = 28, as we obtained FNE scores from a subset of the participants. Red cross indicates female participants). Regression line is computed from the population-level estimate of the FNE scores on selection by client effect in the rTPJ. Dashed lines indicate 2 SEs. d At the evidence stage activity in VS followed client selection switches in adviser selection, i.e., higher when the client switched from the other adviser to you and lower when switched from you to the other adviser (P < 0.005, FWE cluster size-corrected P < 0.05, see Figure S8 for uncorrected map
