Fig. 3: Experiment 1 Results.
From: Parallel development of social behavior in biological and artificial fish
a We studied collective behavior in groups of four fish, measuring the probability of turning left versus right depending on the number of fish on each side. b Common attraction rules in biological fish (top) and artificial fish (bottom 4 graphs). Relationship between the probability of turning to the side with 1 fish in a configuration (1:2), P(1 | 1:2), and the probability of turning to the side with no fish in a configuration (0:3), P(0 | 0:3). Dots indicate experimental data (color coded by age). The dashed line indicates the theoretical line derived from the interaction rule in Hinz & de Polavieja43. c We also studied collective behavior in groups of seven fish, measuring the probability of turning left versus right depending on the number of fish on each side. d Probability of turning to the side with three, four, five, and six biological fish (top) or artificial fish (bottom 4 graphs) in a group of seven fish, for ages 7 (blue dots), 11 (orange dots), and 15 (green dots). Data from the biological fish reproduced from Hinz & de Polavieja43.
