Relaxation of the correlation functions.
(a) The autocorrelation for , and , . The inset shows the collapse of the relaxation regime. In this regime, there is a very weak violation of the dependence of on (time-translation invariance). (b) The collapse of the autocorrelation functions shown in (a) in the relaxation regime indicating sub-aging (). This result shows that the relaxation is strongly dependent on the size of the population ( with ). Here again the value of is set to the average human JND .
