With an eye on uncertainty: Modelling pupillary responses to environmental volatility
Fig 3
B matrices created for the generative process.
Lighter values indicate probabilities closer to 1. As the precision decreases, shown in Figs 3a through 3d, the probability of a number-absence state transitioning to the next number decreases, while the probability of a transition to the preceding number increases. The grey transparent box covers transitions into and within the final 1s break. Separate states are required for each of the number-absence states to ensure this matrix generates a reliable sequence of numbers. Number-absence states following 5,6,7 may transition to the first of the block of 4 number-absence states as the precision decreases, to ensure that the sequence of numbers is always 8 long. These matrices can result in unexpected sequences, as shown in Fig 3e, which is drawn from the matrix defining a scenario with precision = 0.39, since it only has one error.
