makes the same predictions from the third fixation on. Finally, the Gaussian model performed equally well as the SceneWalk models in terms of information gain. Thus we confirm earlier findings that the restriction to nearby saccade targets is the most important influence to include into a model. However, as seen in the previous section, this is not sufficient to explain the DTC over time. 

Across experiments and models, the likelihood declined over time. This was due to the larger variability of later fixation locations between participants. 

## Discussion 

Model simulations showed that adjusting the SceneWalk model with an initial map can reasonably explain the central fixation bias. While the information gain of the Gaussian model was similar, the SceneWalk StartMap model was the only model that generated an
