Fig. 6. Lack of correlation between the directions of the first and second
segments. The directions of the first and second segments with respect to the
direction of F2 from the start and from the turn, respectively (
and
ß in inset), are plotted against each other for successive blocks of 10
trials after the switch. (A) Paths 110: N=70, mean
X=30.47±3.26°, mean Y=3.71±15.62°,
direction of principal axis=92.08°. (B) Paths 1120: N=102,
mean X=26.47±3.435°, mean
Y=7.79±14.355°, direction of principal
axis=89.98°. (C) Paths 2130: N=86, mean
X=25.38±2.78°, mean
Y=7.62±6.9°, direction of principal
axis=80.23°. The closeness of the principal axis to 90° indicates a
lack of correlation between the directions of the two segments.
