动物性格已成为动物行为中的既定概念。尽管如此，早期生活经历对成年人格的潜在影响却常常被忽视。青少年暴露于环境线索（例如同种信号或捕食者线索）可能会提供有关即将到来的环境构成的相关信息。个人也许能够利用这些线索来调整发展轨迹和成人性格，以防止性格与环境不匹配。使用田间蟋蟀Gryllus整数，我们发现在同种声音性信号存在下饲养的个体会改变生长速度和成年人格特征。与在没有声音信号的情况下饲养的雄性相比，在存在声音性信号的情况下饲养的雄性的攻击性较小，并且不太可能成为主导。此外，声处理与幼鱼的体重相互作用：在存在声信号的情况下饲养的大型幼鱼比在存在声信号的情况下饲养的小型幼鱼大，并且比所有在沉默中饲养的幼鱼都大。我们讨论了观察到的发育和人格差异的潜在适应性意义。 (C) 2012 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Animal personalities have become an established concept in animal behaviour. Despite this, the potential influence of early life experiences on adult personality is often overlooked. Juvenile exposure to environmental cues such as conspecific signalling or predator cues may provide relevant information regarding the make-up of the forthcoming environment. Individuals might be able to use these cues to adjust developmental trajectory and adult personality to prevent a personality-environment mismatch. Using the field cricket Gryllus integer, we show that individuals reared in the presence of conspecific acoustic sexual signals alter both growth rate and an adult personality trait. Males reared in the presence of acoustic sexual signals were less aggressive and less likely to become dominant relative to those reared in the absence of acoustic signals. Additionally, acoustic treatment interacted with juvenile body mass: large juveniles reared in the presence of acoustic signals were larger than small juveniles reared in the presence of acoustic signals and larger than all juveniles reared in silence. We discuss the potential adaptive significance of the observed developmental and personality differences. (C) 2012 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.
