Translational biological motion stimuli for perceptual research

B. Aragão; L. Fontes; J. A. Santos; Eduardo Soares; M. V. Correia

Since the studies of Johanson in 1973 the standard stimulus for biological motion perception has been the Point-Light Walker (PLW). This consists of a pattern of moving dots with the common translational component removed as if the target person was walking on a treadmill. The translational motion component has remained as a matter of interest only for researchers on biomechanics and its applications in fields ...

Currently, in NE Portugal, we are advising farmers to adopt ground-cover systems in olive orchards instead of tillage. Most of soils are on steep slopes and have very low organic matter content (Arrobas and Rodrigues, 2002). This consequently creates huge problems for soil conservation. However, we need strong arguments to convince the farmers. Tillage in a very old and ingrained practice; it is easy, pleasant ...
