Abstract:
Abstract: A series of studies were conducted to test the
rotation and translation hypotheses of the effects of unilateral
transcutaneous mechanical vibration (TMV) of the posterior neck
muscles on the representation of space. Subjective midline and eye
height were measured at 40 cm, 50 cm, 60 cm, and 120 cm from the
center of the participants' heads. While the measurements at 60 cm
and 120 cm are consistent with the rotation hypothesis, the overall
pattern of measurements is consistent with neither the rotation nor
the translation hypothesis. We propose that these results indicate
a transition from an egocentric representation of space to a
face-centered representation of space as distance to target
decreases.
