Fig. 4. Loading had no effect on the number of loops made by the leg for either the anterior stimulus site (A, N=220 trials pooled across three animals) or the posterior site (B, N=233 trials pooled across three animals). Bars show the relative frequency of occurrence of scratches with either 1, 2, 3 or more cyclic loops under each load condition. See text for details. Open bar, 0 loops; Light grey bar, 1 loop; mid-grey bar, 2 loops; black bar, 3 loops.
