Corrigendum to “Two thumbs and one index: A comparison of manual coordination in touch-typing and mobile-typing” [Acta Psychologica 167 (2016) 16–23](S0001691816300518)(10.1016/j.actpsy.2016.03.007)

We provide here a corrected version of Table 4. The changes made to the previous version are the following: First, we changed the correlation coefficient nomenclature “r” for “rs”, as it is considered a more appropriate nomenclature of the Spearman's correlation. Furthermore, a column was missing in the original table. Seven coefficients were reported instead of the eight coefficients mentioned in the body of the text. The missing data is the correlation coefficient between bigram frequency and IKIs for the “two-hands” group in the mobile-typing task, for the No transition IKIs. The missing value is rs = -.50***. In addition, we corrected two coefficients, one in the fourth column (rs =-.39** instead of -.41*) and one in the sixth column (rs =-.45*** instead of -.54**). Finally, we corrected the asterisks that indicate significant p values: in fact, the p-values are lower than previously indicated. The changes in the new version of Table 4 do not alter the results of the analysis and their discussion. As we wrote in the Section 3.1.2, results indicated a strong negative correlation between bigram frequency and IKIs in all the analyzed samples, except for the “one-hand” group in the mobile-typing task (for transition bigrams), where no correlation was found.
