Fig. 3: Behavioral signature of uncertainty-driven arbitration between experiential (EL) and observational learning (OL).

A, B The proportion of OL choices was computed like in Fig. 2C,D, but separately for each of 4 trial types defined by OL uncertainty (low or high) and EL uncertainty (low or high), for Study 1 (A) and Study 2 (B). See Methods for details about how uncertainty trial types were defined, and Fig. 1B for an illustration. Each dot is an individual participant; error bars represent SEM. C, D Separate mixed-effects generalized linear models (ME-GLM) were run to quantify the effect of each uncertainty manipulation on EL (blue) and OL (orange) separately. Both fixed and random effects of past partner’s action and past outcome, for high and low uncertainty trials, were included into the ME-GLM, allowing us to quantify each effect for low and high OL uncertainty trials (left), and low and high EL uncertainty trials (right), for Study 1 (C) and Study 2 (D). Data represent the fixed effect coefficient estimates for each uncertainty trial type; error bars represent the standard error associated with those estimates; and each dot is an individual participant (random effect); Study 1: N = 126 independent participants (A, C); Study 2: N = 493 independent participants (B, D). See Table S1 for statistics.
