**4. Switching of handedness as a form of learning effect?**

In the earlier cited studies, the Cognitive-Kinesthetic Drawing Training was designed and applied as a noninvasive intervention for a rapid enhancement of *spatial memory*, *spatial cognition* in general, and precise *memory-guided motor control* in both the blind and the sighted. The memory drawing protocol in the form developed for this training, fully engages the whole *perception-cognition-action loop* [3–4], which was a key element of my *conceptual framework* underlying the training. (Note here the expansion of the traditional "perception-action" loop to include the central component of "cognition" (**Figure 2**), as I believe it is critical to its generalization to the gamut of spatial-cognition abilities.)

**Figure 2.** Perception-Cognition-Action Loop. Note the inclusion of the *cognition* module as a central mediator into the traditional perception-action loop [4].

In this chapter, we ask whether the learning effect of this training could extend to the *action* component of the processing *loop* involved. Specifically, can it drive reorganization of motorarchitecture for *switching handedness*?
