Fig. 3. Acquisition curves and test-phase response probabilities P by odour, for the differential conditioning experiments. (A,B) Differential conditioning of 1-heptanol and 1-hexanol (N=40); (C,D) 1-hexanol and 1-octanol (N=50); (E,F) 1-hexanol with 2-octanone (N=60). R, reinforced and N, non-reinforced odours in the acquisition phase. Lowercase letters above values denote results of one-tailed t-tests between means (P<0.05); like letters indicate non-significance. Note that data from the third group (E,F) were analyzed using GLM, not t-tests. Differences in N reflect the different numbers of test odourants used in each group (N=10 for each number of odours).
