, As to the behavioural score, the analysis revealed that there was a statistical significant difference in the score for alerting behavioural response between visual stimuli (? 2 4 = 45.356, p < 0.001; Friedman's ANOVA, figure 4b)

, Similarly, the analysis revealed higher alerting behavioural response between B-Cat and the other visual stimuli with the exception of RG-Cat-2: B-Cat (3.50 ± 0.36; m ± s.e.m.) versus G-Background-1, G-Background-2 and RG-Cat-6 (p < 0.001). No other significant statistical differences were found

B. 5a, Friedman's ANOVA revealed a main effect of the type of visual stimulus on the mean looking time (? 2 4 = 19.885 , p = 0.001) (figure 5a). Dunn's post hoc test revealed that this main effect was owing on, 2017.
