Fig. 5. Three trial days are sufficient to characterize aggression.

a–c The raw screening data for experimentally naïve, sexually experienced CD-1 male mice (n = 25) during a 10-day resident-intruder screening. a Bout number for days 1–10. Day 1 is different than all other trial days (p < 0.0001). Bout number on day 5 is also different from that of day 7 (p < 0.05). b Latency for days 1–10. Day 1 is different from all other trial days (p < 0.0001). There are no other differences between trial days. c Duration for days 1–10. Day 1 is different (p < 0.001) from days 2–6, but not 7–10. Duration on day 4 is also different from duration on day 10 (p < 0.05).
