Probability of SOR. A. Probability of the SOR as a function of the dipole-object's position along the body of the fish. Black filling represents a single SOR, medium grey two, and light grey bars three consecutive responses, respectively. The total probability of a SOR is given by the white bars. Numbers above the graphs show the absolute number of stimuli (100%) at each position. B. Box-and-Whisker plot of the amplitude (peak amplitude) of the SOR as a function of distance. SOR amplitude were almost constant at object distances of 1 to 12 mm, while amplitudes decreased at a distance of 15 mm C. Box-and-Whisker plot of the peak amplitude of the SOR as a function of dipole position. SORs declined in amplitude form rostral to caudal along the fish's body. In B and C horizontal lines above the plots summarise the results of the Dunn post-hoc test (p < 0.05). Data labelled FAR in B and C indicates the false alarm rate amplitudes.
