Behavioural responses obtained with natural, synthetic control and experimental series on pups.

Comparison of behavioural scores obtained between 1) the synthetic and the natural controls, and 2) the synthetic controls and the modified signals (Wilcoxon matched pair tests, p values were adjusted using the Holm's Sequential Bonferroni Procedure, T and Z are statistic values for n<15 and n>15 respectively). Behavioural scores obtained with modified signals were compared to the average scores obtained with the different synthetic signals (Moy. Synth).
