Phi fluctuates with surprisal: An empirical pre-study for the synthesis of the free energy principle and integrated information theory
Fig 8
Average fluctuations in Φ and surprisal on trial time split into trials with negative (purple, coef. < -0.1, N = 4489), neutral (grey, coef. in (-0.1, 0.1), N = 1532) and positive (brown, coef. > 0.1, N = 5611) correlations between Φ and surprisal. A) average surprisal over trial time. B) average surprisal over trial time, centered around the first observation of the block. C) average Φ over trial time. D) average Φ over trial time, centered around the first observation of the block. Shading around lines is the standard error of the mean.
