Abstract

Aggressive individuals are predicted to make fast but error-prone decisions. However, this relationship does not always hold true. When it comes to decision-making in a specialized spider-eating jumping spider Portia labiata, we found that aggressive spiders make faster decisions than docile spiders, regardless of task difficulty. However, accuracy in decision-making depends on both aggressiveness and task difficulty. Aggressive spiders make more accurate decisions in the simple task, while docile spiders make more accurate decisions in the difficult task.
