Proportions (%) of 2- or 3-day-old newborn rabbits responding behaviorally (sucking response) to the odorant A (ethyl isobutyrate), the odorant B (ethyl maltol), their AB or A’B’ mixtures (respectively, at a ratio of 30/70 and 68/32 of the two components), and the AC mixture (C: guaïacol; ratio 50/50) after a single conditioning to the AB mixture or to one of its components. The results show that after conditioning to AB, the pups respond both to the odorants and the different mixtures. Therefore they perceive the elements A and B during the learning episode. However, after conditioning to odorant A or B, they respond to the conditioned odorant but not to the AB mixture; nevertheless, they respond to the A’B’ and AC mixtures. Thus, newborn rabbits perceive the odor of a configuration in the AB mixture in addition to the odors of each odorant, while they perceive only (or mainly) the elements in the A’B’ and AC mixtures (adapted from Coureaud et al., 2008, 2009, 2011).
