A positive coefficient indicates that the dependent variable (curvature or velocity-profile deviation) increased with an increase in the value of the variable or increased in the presence of that variable (for binary variables). (*) Horizontal saccades were compared to not-horizontal saccades and likewise for vertical and oblique saccades. Leftward saccades were compared to rightward saccades. Downward saccades are compared to upward saccades. (∇) Comedy had lower curvature and velocity-profile deviation compared to each of the other movie genres, documentary, animation, drama and action.
