研究“动物个性”的相关性涉及到将个体之间和个体内部一致的行为变化与野外的适应性联系起来。旨在做到这一点的研究通常是在圈养条件下分析人格，并依赖于实验室中测量的特质反映了它们在自然界中的表达的假设。我们研究了这个很少测试的假设，通过比较实验室和野外测量的行为，野生蟋蟀（蟋蟀），通过不断监测个人的行为在自然界中，并反复捕捉相同的个人，并测量他们的行为在圈养。我们关注了人格研究中经常检查的三个特征：害羞，活跃和探索。所有这些都在实验室中表现出重复性。实验室活动和探索预测了他们在野外的同等行为的表达，但害羞没有。可以预见，野生环境中的性状会受到温度和阳光等环境因素的影响，但只有活动表现出明显的个体内重复性。这表明，一些通常作为人格特征研究的行为可以在圈养中准确地进行分析，但其他行为的表达可能是高度特定的。我们的研究结果强调了验证实验室行为测定与野外测量的类似性状的相关性的重要性。
Examining the relevance of ‘animal personality’ involves linking consistent among- and within-individual behavioural variation to fitness in the wild. Studies aiming to do this typically assay personality in captivity and rely on the assumption that measures of traits in the laboratory reflect their expression in nature. We examined this rarely tested assumption by comparing laboratory and field measurements of the behaviour of wild field crickets (Gryllus campestris) by continuously monitoring individual behaviour in nature, and repeatedly capturing the same individuals and measuring their behaviour in captivity. We focused on three traits that are frequently examined in personality studies: shyness, activity and exploration. All of them showed repeatability in the laboratory. Laboratory activity and exploration predicted the expression of their equivalent behaviours in the wild, but shyness did not. Traits in the wild were predictably influenced by environmental factors such as temperature and sunlight, but only activity showed appreciable within-individual repeatability. This suggests that some behaviours typically studied as personality traits can be accurately assayed in captivity, but the expression of others may be highly context-specific. Our results highlight the importance of validating the relevance of laboratory behavioural assays to analogous traits measured in the wild.
