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.
