Abstract:
Proactive animals are assumed to make quicker but inaccurate decisions. However, this does not seem to be the case for one species of jumping spider with high cognition ability. In this study, we tested the existence of aggressiveness in this jumping spider species and found that, in the prey choice decision-making, more aggressive individuals were more likely to make fast decisions but they also performed as accurately as less aggressive individuals.
