Fig. 4. Activation times (the latency for initiating searching) for sham control animals (group C) and eight groups of animals with specific sensory ablations of the antennules (groups 1–8). The groups are defined in Table 1 and are the same as in Fig. 3. An asterisk indicates that the activation time for a group of ablated lobsters is significantly different from that for the sham control lobsters (two-sample randomization test for median difference as the statistic; P lower than the critical value for a 5 % experiment-wise error rate as determined by a sequential test using the Dunn–
idák method for eight planned comparisons) (Sokal and Rohlf, 1997). The horizontal dashed line indicates the maximum time (10 min) allowed for each lobster to become activated. For each group of lobsters, the median (
) and upper and lower quartiles are shown. Each group of ablated lobsters represents 10 animals, and the group of sham control lobsters contains 11 animals. This graph was prepared using the mean activation time from the two trials for each animal.
