该假设部分基于社会互动的发现，即攻击性小鼠在受到威胁的情况下通常采取主动行为策略（如战斗-逃跑），而非攻击性小鼠通常采取被动策略（如保护-撤退），该假设使用双向主动避冲击范式进行了测试。总体而言，研究发现攻击性小鼠比非攻击性小鼠更能主动避免电击；这一发现与我们的假设一致。然而，在非攻击性小鼠中，在高回避个体和低回避个体中发现了明显的二分法。高回避组的高试间活动和低回避组的低活动分别被解释为主动与被动策略的另一个指示。因此，得出的结论是，并非所有不具攻击性的老鼠都采取被动策略，但有些老鼠采取主动策略，就像所有具有攻击性的雄性老鼠一样。
The hypothesis, partly based on findings in social interactions, that aggressive mice generally adopt an active behavioural strategy (cf. fight-flight) in threatening situations, while non-aggressive ones generally assume a passive strategy (cf. conservation-withdrawal) was tested using a two-way active shock avoidance paradigm. Overall, aggressive mice were found to be better active shock avoiders than non-aggressive animals; a finding that is consistent with our hypothesis. However, within the non-aggressive mice a clear dichotomy in high and low avoidance individuals was found. The high intertrial activity in the superior avoidance groups and the low activity in the poor avoidance group was interpreted as another indication of an active versus passive strategy respectively. Accordingly, it was concluded that not all non-aggressive mice assume a passive strategy, but that some mice adopt an active strategy, like all aggressive males.
