Fig. 7. Mean homing directions of two subjects in experiment II. The homing directions are measured at a distance of 50 cm from the point of departure of the return. The mean return vectors (arrows) are superimposed on the outward trip to the food site (solid lines; circling not shown). The four vectors in each graph represent the homing directions of subjects 1 (solid arrows) and 2 (dashed arrows) in clockwise and counterclockwise trials. Vectors from counterclockwise trials are presented mirror-reversed. (Solid arrowheads, P<0.05; open arrowheads, P>0.05; test of Rayleigh.) Circle NDR represents the location of a virtual nest that would result from a partial resetting acting on the subject's azimuth only.
