Fighting animals use a variety of information sources to make strategic
decisions. A neglected potential source of information is an
individual's own performance during a fight. Surprisingly, this
possibility has yet to be incorporated into the large body of theory
concerning the evolution of aggressive behaviour. Here, by experimentally
dampening the impact of their shell rapping behaviour, we test for the
possibility that attacking hermit crabs monitor their own fight
performance. Attackers with dampened raps did not show a reduction in the
number of raps used. By contrast, they showed an increased frequency of a
less intense agonistic behaviour, shell rocking. This change in behaviour,
in attackers that are forced to rap weakly, indicates that they assess
their own agonistic behaviour.

and dampend shell rapping. Predictors: Treatment Group (Categorical),
Outcome (Categorical), RWD (Continuous). Responses: Bouts of rocking,
