A Corrigendum on
Economy of Effort or Maximum Rate of Information? Exploring Basic Principles of Articulatory Dynamics

by Xu, Y., and Prom-on, S. (2019). Front. Psychol. 10:2469. doi: 10.3389/fpsyg.2019.02469

In the original article, there were two errors in Equation (5). The lower limit of the summation should be i = 0 rather than i = 1. The denominator in the fraction should be (k – i)! rather than (N – k)!

A correction has been made to Equation (5). The corrected equation appears below.

ck={y(0)−b,k=0yk(0)+c0λ−m,k=11k! (yk(0)−∑i=0k−1k!(k−i)!ci(−λ)k−i),k≥2    (5)

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.

Keywords: maximum rate of information, economy of effort, stiffness, peak velocity, target approximation
