A Corrigendum on
The Influence of Chronic Pain and Cognitive Function on Spatial-Numerical Processing by Spindler, M., Koch, K., Borisov, E., Özyurt, J., Sörös, P., Thiel, C., et al. (2018). Front. Behav. Neurosci. 12:165. doi: 10.3389/fnbeh.2018.00165 In the original article, there was a mistake in Tables 1-4 as published. The tables show the data for n = 37 chronic pain patients and n = 37 matched healthy controls. However, the tables should have shown data for n = 42 chronic pain patients and n = 42 matched healthy controls. The corrected Tables 1-4 appears below.
Additionally, there was a mistake in the legend for Table 1 as published. The scaling of the variables "education" and "opioid medication" was incorrect. The correct legend appears below.
† The total amount of participants reporting different pain syndromes. In brackets, only the corresponding main pain category of each participant is listed." Lastly, in the original article, there was an error. The number sense performance of patients with vs. without opioid medication, was compared using the same incorrect sample size as mentioned above.
A correction has been made to the Results, Experimental Tests and Questionnaires, Clinical pain assessment, and number sense.
"Finally, the role of opioid medication on number sense performance was evaluated, suggesting that patients with opioid medication performed equally well on both number naming [n = 13; M = 4.7, SD = 1.7, t The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.

Conflict of Interest Statement:
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. SD, Standard deviation; ADS-K, General Depression Scale -Short form; *education refers to 0 = no degree, 1 = lower secondary education, 2 = secondary school, 3 = A-levels, 4 = university degree; **on an 11-point Numerical Rating Scale (0 = no pain; 10 = worst pain imaginable) on the day of testing. † The total amount of participants reporting different pain syndromes. In brackets, only the corresponding main pain category of each participant is listed. On the left, the Mean Absolute Deviation from the Expected Respective Response (MADER) is shown for each subtask of number line experiments for controls and pain patients. On the right, results of statistical analyses for differences between group MADERs for each experimental condition are displayed. SD, standard deviation; *p < 0.005 (Bonferroni-corrected alpha-level).
