24 Rothkegel et al. Figure 7 . Comparison of mean horizontal distance of gaze from starting position for the exper- imental data and three models. Examples of scanpaths for (a) experimental data, (b) Gaussian weighted random sampling from density map, (c) SceneWalk model (Engbert et al., 2015) based on target selection from dynamic activation maps (d) SceneWalk model with a reduced strength of the inhibition map (e) random sampling from density map and (f) Saccadic momentum model. (g) Mean horizontal distance X$_{MHD}$ ( t ) of gaze position at time t shows that the qualitative be- havior in the experimental data with an overshoot component to the image side opposite to the starting position is reproduced by the SceneWalk model that uses inhibitory tagging as a driving mechanism. 0 6 12 18 0 2000 4000 6000 8000 10000 Time [ms] Distance to Starting Position [°] Model T ype Exper imental Data Gauss Model Scene W alk Model Scene W alk Model Reduced Inhibition Density Model Saccadic Momentum Model ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Exper imental Data Gauss Model Scene W alk Model SWM Reduced Inhibition Density Model Saccadic Momentum Model (a) (b) (c) (d) (e) (f) (g)
