The color phi phenomenon: Not so special, after all?

A four-neuron model for demonstrating stimulus-response arrival order reversals.
(A) The model. See below Eq (6) for parameter values. (B) A Scan over stimuli intervals Δtin = tin,b − tin,a showing the influence on response times RTa = tout,a − tin,a (red), RTb = tout,b − tin,b (blue) and the response time interval Δtout = tout,b − tout,a (black). For a certain central region of the input interval, there exists a reversal of the order in which responses happen, compared to the order in which the stimuli were applied. (C) Scan over stimuli intervals and amplitude ratios, illustrating how temporal and amplitude-related stimuli characteristics influence their temporal perception. (D) Detailed signals for tin,b ≫ tin,a such that the output order corresponds to the input order. (E) Detailed signals in the input-output reversal regime, where Δtin > 0 and Δtout < 0.
