Figure 6.

Perceived distances after a 30-min retention period. Larvae are trained and tested differentially in the same way as in the experiment displayed in Figure 5; however, testing is performed only after an additional 30-min retention period. The arrows indicate perceptual distances; apparently, after this retention period, there are no significant differences among odor pairs in terms of their perceived distances. ns: KW test: P > 0.05; N =12 in all cases. For the underlying preference data, see Fig. S4. The numbers below the plots refer to the distance rank of the respective odor pair (see Table 1). Other details are described in Figure 2. This figure appears in color in the online version of Chemical Senses.
