Fig. 7. The angular difference between the reference e-vector and the comparison
e-vector (
e-vector) is plotted against the percentage of choice
frequency for each fish. Each point represents the percentage of correct
choice frequency (mean ± S.E.M.)
between the reference e-vector and the comparison e-vector (40 trials per
fish, N=4). The horizontal shaded bands represent the range of choice
frequency values that correspond to significance levels of
P=0.001
x, P=0.01
x
0.001 and
P=0.05
x
0.01, calculated using the binomial
probability function for 40 Bernoulli trials. The smallest
e-vector
was approximately 25° in all four fish.
