Results of Control Experiment B. The Y-axis refers to the proportion of choices for the bigger hole in the four versions (ratio 0.75) tested. Values in brackets represents the diameters of the larger and the smaller hole. Asterisks (*) denote a significant departure from chance level (0.5). Bars represent the standard error. The dashed red line represents the zebrafish’ performance in the ratio 0.75 in the Experiment 1 (mean = 0.602).
