熟练的格斗不仅包括一个人准确有效地进行格斗行为的能力,还包括根据现有信息从其所有技能中选择最适当的行为或战术的能力。不同战术的效力可能取决于对手的行为和个人的内部状态,例如,随着时间的推移,随着疲劳的出现,特定行为可能变得不那么有效。此外,由于战斗是动态的相互作用,选择适当战术的能力需要快速的信息处理,因此可能受到个人认知能力的限制。在这里,我们进行了一个三阶段的实验,以调查的影响,降低性能的能力,暴露于缺氧和决策速度熟练的战斗在欧洲寄居蟹,Pagurus bernhardus。在战斗中,攻击者试图通过敲击防御者的外壳或前后摇晃防御者的外壳来引起驱逐。通过分析暴露于缺氧和决策速度对这些策略的相对使用的影响,我们发现,与我们的预测相反,无论是性能能力还是决策速度都不能单独预测所执行的行为类型。相反,这两个特征相互作用,以确定攻击者需要施加多少努力(说唱和石头)来引起驱逐。此外,我们表明,虽然没有表现能力,也没有决策速度预测的技能时,战斗作为一个整体进行分析,这些变量的影响变得明显时,分析的准确性变化的战斗进展,可能是由于疲劳的累积效应。
Skilful fighting encompasses an individual's ability not only to perform agonistic behaviours accurately and efficiently, but also to choose the most appropriate behaviour or tactic from its repertoire based on the information available. The efficacy of different tactics may depend both on the behaviour of the opponent and on the individual's internal state, for example a specific behaviour may become less effective over time as fatigue sets in. Furthermore, because fights are dynamic interactions, the ability to choose the appropriate tactic will require rapid information processing and may thus be constrained by an individual's cognitive ability. Here, we conducted a three-phase experiment to investigate the effects of reduced performance capacity induced by exposure to hypoxia and decision-making speed on skilful fighting in the European hermit crab,Pagurus bernhardus. During fights attackers attempt to elicit an eviction either by rapping on the defender's shell or by rocking the defender's shell back and forth. By analysing the effect of exposure to hypoxia and decision-making speed on the relative use of these tactics, we show that contrary to our prediction, neither performance capacity nor decision-making speed alone predicted the type of behaviour performed. Rather, these two traits interacted to determine the amount of effort (raps and rocks) attackers needed to exert to elicit an eviction. Furthermore, we show that while neither performance capacity nor decision-making speed predicted skill when fights were analysed as a whole, the effects of these variables became apparent when analysing the change in accuracy as fights progressed, likely due to the accumulating effects of fatigue.
