Temperament traits are often measured under artificial conditions, which may not necessarily predict behaviour in naturalistic contexts. A reliable behavioural assay should yield similar results as tests performed under alternative conditions, but this is not frequently evaluated in free-living animals. Eastern box turtles (Terrapene carolina) exhibit individually consistent boldness behaviour in an artificial confinement assay, so we tested turtles repeatedly using the confinement assay along with a simulated predator attack assay. Turtles that were bolder during the confinement assay tended to also be bolder after the simulated predator attack, suggesting temperament is not context-specific. Bolder turtles also employed active defences (e. g., fleeing or biting) more often, demonstrating that different behavioural measures yield similar findings. Boldness in these turtles appears to be a generalized temperament trait, and similar procedures could be used in other species as well to establish the sensitivity of behavioural assessments in the field to assay conditions.
