Correction to: Cognitive Processing (2018) 19:375–385 https://doi.org/10.1007/s10339-017-0853-2

The following errors require correction in the article. The authors apologize for these errors.

  1. 1.

    In the abstract, the term “dyslexia” should be replaced by the term “dyscalculia”. Furthermore, the mean age of the experimental group was not “129.74 months” but “115.29 months”, whereas the mean age of the control group was not “126.9 months” but “116.07 months”.

  2. 2.

    In the section “Participants” the mean ages of the experimental group and of the control group should accordingly be replaced by “115.29 months (SD = 3.60 months)” and “116.07 months (SD = 1.07 months)”, respectively.

  3. 3.

    In the section “Training Effects”, t (2.05) should be replaced by t (26), and t (15) should be replaced by t (13).

  4. 4.

    In Table 2, the titles “Control group” and “Experimental group” should be swapped, and the title “Difference (= 2.05) (ns)” should be replaced by “Difference, t (26)”. In the row “Age”, “M = 116.00, SD = .00” should be replaced by “M = 116.07, SD = 1.07”, and “t = − .74” should be replaced by “t = .78”. In the row “Mental calculation”, “M = 9.43, SD 1.15” should be replaced by “M  = 9.57, SD = 1.08”. The correct table is reproduced below.

  5. 5.

    In Table 3, the titles “Control group” and “Experimental group” should be swapped. In the row “Dictation of number”, Cohen’s d “0.25” should be replaced by “2.50”. In the row “Total math”, “M = 38.36, SD = 1.59” should be replaced by “M = 38.57, SD = 1.82”. The correct table is reproduced below.

  6. 6.

    In Table 4, all negative values should be positive. In the row “Total math”, “− 1.00” should be replaced by “.79”. The correct table is reproduced below.
