Corrigendum: Modeling habits as self-sustaining patterns of sensorimotor behavior

A corrigendum on
Modeling habits as self-sustaining patterns of sensorimotor behavior

In this article, Equation 8 is incorrectly written:

$\begin{array}{cc}\Gamma (a,N_v)=a-a·\frac{N_v}{\left|\right|N_v\left|\right|},& \left(1\right)\end{array}$

The correct equation is:

$\begin{array}{cc}\Gamma (a,N_v)=a-\left(a·\frac{N_v}{\left|\right|N_v\left|\right|}\right)\frac{N_v}{\left|\right|N_v\left|\right|},& \left(2\right)\end{array}$

where the right-hand-side of the equation represents the vector a with its component parallel to N_v removed.

In the paper, this function is used to calculate the “attraction” influence of nodes. The vector a is the difference between the node's position (N_p) and the current sensorimotor state (x), and Γ removes the component of a that is parallel to N_v.

All of the simulations presented in the original paper were performed with the correct evaluation of Γ(a, N_v). This was only a typo in the manuscript.
