Mean normalised weight for five different spatial positions for the simultaneous condition. Results are shown for each BPN separately (light blue circles, the numbers in the symbols indicate the BPN number with 1 referring to the lowest and 5 referring to the highest centre frequency) and averaged across all BPNs (dark blue circles). Error bars indicate plus and minus one interindividual standard error. For a better visibility, the symbols of BPN3 and BPN4 are slightly shifted horizontally against each other. The grey dashed line indicates a uniform weight across all positions.
