Comparison of dynamic (effortful) touch by hand and foot.
Spatial perception by dynamic touch is a well-documented capability of the hand and arm. Morphological and physiological characteristics of the foot and leg suggest that such a capability may not generalize to that putatively less dexterous limb. The authors examined length perception by dynamic touch in a task in which weighted aluminum rods were grasped by the hand and wielded about the wrist...
متن کاملEffortful touch with minimum movement: revisited.
The ecological static moment-torque model proposed by C. Carello, P. Fitzpatrick, I. Domaniewicz, T.C. Chan, and M.T. Turvey (1992) does not uniquely explain the perception of rod length by static holding. Guided by a mechanical analysis of the gravitational forces and torques produced in the hand as it statically holds rods of different lengths and materials at different orientations, we offer...
متن کاملDynamics of effortful touch and interlimb coordination.
In biological movement systems, the level of muscular-articular links is responsible for assembling highly reliable, stable, and reproducible coordination patterns involving very many joints and muscles. Research shows that the important perceptual capabilities of this level arise from the bulk sensitivity of muscles and tendons, so-called effortful or dynamic touch, to the quantities of rotati...
متن کاملPeripheral neuropathy and object length perception by effortful (dynamic) touch: a case study.
The spatial extents of hand-held objects can be perceived nonvisually by wielding them. This ability of effortful or dynamic touch to exploit the mass moments of an object to perceive its length was evaluated with a 40-years old right-handed woman with surgically treated Arnold-Chiari Type 1 Malformation and cervical syrinx. At the time of the experiment she presented with loss of discriminativ...
متن کاملDynamic touch.
People can perceive a number of spatial and other properties of objects, without the benefit of vision, simply by wielding and hefting the objects. A variety of recent experiments are reported, showing that in this kind of touching, which is closely connected with the states of muscles, the nervous system cleverly exploits the physics of rotations.
