    • Reflective balls were attached to the end of the stick (mass ∼0.25 gr). Infrared light reflected from these markers is detected by two specialized motion capture cameras (Qualisys, Inc.). The image projected on the CCD of each camera determines two of the spatial coordinates; the third spatial coordination is determined by using triangulation techniques involving both cameras.

    • Construction materials (e.g., wood, metal, synthetics) were chosen so that the mass of the stick remained the same (35 gr) as the length varied.

    • The frequency of this peak is greater than that of the heartbear (∼1.2 Hz) and was present in the power spectra obtained when a subject closed their eyes and moved their hand in a manner analogous to the movements during stick balancing. Under these conditions, the power spectra did not contain a significant region with slope -1/2.
