Erratum to: Cognitive Enhancement of Numerical and Arithmetic Capabilities: a Mini-Review of Available Transcranial Electric Stimulation Studies (Journal of Cognitive Enhancement, (2017), 1, 1, (39-47), 10.1007/s41465-016-0006-z)

In the article, incorrect descriptions appeared in the table note (Table 1). The correct description for anode and cathode target regions refers to the international 10–20 system for electrode placement. The correct benchmarks for Cohen’s d are: 0.2 = small effect, 0.5 = medium effect, 0.8 = large effect. The conclusions presented in the article are not affected by these mistakes. The authors declare that all these points have already been addressed in the proof correction process, but were not handled satisfactorily by the publisher.
