Figure 3
Actual learning rates and estimated parameters. (a) Acceleration of learning during the initial appearance of objects due to different degrees of temporal context. In the presence of a fully predictive temporal context, the accumulation of information was accelerated by 0.13 bit. Error bars in Figure 3a show the standard deviation across experiments for each object type. Plots (b)-(f) show regions of optimal values in the parameter space (ϵ, γ), corresponding to the general learning rate and the recognition parameter, respectively. The color scales to the right of each plot refer to the fit quality f
Q
for each parameter pair (ϵ, γ), which was computed as 
, where 
and 
are the mean values of performance correct in the i-th appearance for human observers and for the model simulations, respectively, and 
and 
are the corresponding standard deviations. The higher the f
Q
values, the better the fit between measured and predicted data.
