我提出了一个“累积评估模型”，它描述了二元对抗性遭遇，其中参赛者决定是坚持还是逃跑是基于对手行动的累积总和。它与仪式化的战斗特别相关，在这种战斗中，只能容忍一定程度的直接物理伤害，但它也可以应用于没有身体接触的展示，只要它们受到外部时间成本（例如捕食风险）的影响。累积评估模型提供了顺序评估模型或消耗战的替代方案，作为时间扩展显示的描述。我描述了如何通过考虑升级特性和特征性群体内变异在实际情况中区分这三者。该模型预测，在某些情况下，输家可能会以较低的强度开始战斗，但比赢家更快地提高强度。这种行为已在鲤鱼 Aphyosemion striatum 中观察到。 (C) 1998 年动物行为研究协会。
I present a 'cumulative assessment model', which describes dyadic antagonistic encounters in which a contestant's decision whether to persist or to flee is based upon a cumulative sum of its adversary's actions. It is particularly relevant to ritualized fights in which only a certain total of direct physical damage can be tolerated, but it can also be applied to displays without physical contact provided they are subject to external time costs (such as from predation risk). The cumulative assessment model provides an alternative to the sequential assessment model or the war of attrition as a description of temporally extended displays. I describe how the three may be distinguishable in real situations by consideration of escalatory properties and of characteristic intrapopulation variation. The model predicts that, under some circumstances, losers may start the encounter at a lower level of intensity but increase that level more rapidly than winners. Such behaviour has been observed in the cyprinodont fish Aphyosemion striatum. (C) 1998 The Association for the Study of Animal Behaviour.
