(A) Group distribution of the Probability of a Change of Movement (PCoM) for the six types of CoM trials (1. 3–3/1–5; 2. 3–3/5–1; 3. 1–5/3–3; 4. 5–1/3–3; 5. 1–5/5–1; 6. 5–1/1–5). (B) Group average and standard error of β-regression coefficients of full GLMs performed on the binomial p parameter fitted to the PCoM, as a function of three factors: reward Gain (G), Time of presentation of the second distribution of visual reward (T), Peak tangential Velocity (PV), and their covariates. The PCoM exhibits a main increasing effect of G (F(15,1) = 120.32, p = 1.37E−8) and a decreasing effect with PV (F(15,1) = 6.91, p = 0.021), as well as an interaction (F(15,1) = 9.21, p = 0.0084) (*****p < 1E−5, ****p < 1E−4, ***p < 1E−3, **p < 0.01, *p < 0.05). (C) Group PCoM boxplots as a function of G, fitted using a sigmoid (METHODS). (D) Group pCoM (binomial fit p-parameter) boxplots as a function of G. (E) Group PCoM boxplots as a function of PV. (F) Group PCoM boxplots as a function of G and PV.
