Fig. 3: Discrimination of bar stimuli with different numerosity in zebrafish larvae.
From: Quantity discrimination in newly hatched zebrafish suggests hardwired numerical abilities
a Bar stimuli used in the first numerical discrimination experiment. b Preference for the choice sector with the larger numerosity and for the choice sector with the smaller numerosity, divided according to the numerical ratio of the stimuli (N = 180 subjects); large dots and error bars represent means and standard errors, respectively; small dots indicate individual data points; asterisks represent a significant difference (P < 0.05) in the time spent in the two choice sectors. c Preference for the choice sector with the larger numerosity and for the choice sector with the smaller numerosity divided according to the stimuli’s control type (N = 180 subjects); large dots and error bars represent means and standard errors, respectively; small dots indicate individual data points; asterisks represent a significant difference (P < 0.05) in the time spent in the two sectors.
