Table 1.
Estimates for the probability of first choice in the three experimental designs (visible prey, n = 20; hidden prey, n = 34; and odor‐visual separation, n = 13) and the combination of the visible and hidden prey experimental designs. In addition, the between‐treatment differences are shown for each experimental design, and the probability that these differences are greater than 0 (Probability A > B)

All estimates are the means and standard deviations derived from the Bayesian posterior distributions of the multinomial analyses.
