Neuro-cognitive processes involved in estimating others’ and one’s own ability to inflict harm and other fitness-related costs in physical confrontation based on available cues related to the likelihood of success in physical conflict.


When organisms are competing for the same resource there are multiple strategies that each individual might take. They might cooperate, they might try to scramble to outcompete, they might leave and seek alternative sources, or they might aggressively compete (Duntley 2005). This last choice is a decision to inflict costs on the other and is likely made where at least one of the other strategies are available. It is therefore an interesting question to analyse when and how organisms decide to aggressively compete.

While a number of factors will be at play in the wider context, such as the value of the resource and how divisible it is, for our purposes here we focus on...
