In our publication (Han, Saunders, Woods, & Luo,

2013), we made some errors that we amend here. These errors relate to (a) the criteria used for saccade detection and (b) the calculation of the proportion of the saccade that had occurred.

The speed criterion was 30°/s, and the duration threshold was 10 ms, rather than the parameters of the algorithm reported in the publication (speed >20°/s; duration >20 ms; first paragraph in Results section, p. 6). The number of detected saccades was 3,033 saccades (1,162 with the Eyelink and 1,871 with the DPI system). The revised

Figure 4 (below) shows the correct histograms of the distribution of saccade amplitudes. The sample size was incorrectly reported throughout the publication, including in the abstract.

The proportion of saccade amplitude was not calculated correctly. This affected Figures 7c, 7d, 8c, 8d, 9a, 9b, 9c, and 9d, introducing a slight upward shift of the data, which has been fixed in the revised

Figures 7,

8, and

9 (below).

This does not change the overall interpretation of the results or our conclusions.
