探索陌生环境和加入行为中的个体差异可能反映了作为风险相关行为的羞怯-大胆连续体。我们通过实验研究了在不熟悉的实验室环境中，阿拉斯加三棘棘鱼在探索活动中的个体变化与追随其他同种生物的趋势之间的关系。这些同种生物主要是浅滩浮游生物和底栖生物（机会性浅滩底栖动物）。在迷宫水族箱中，我们首先观察了探索活动的个体差异，即单个未成熟的鱼在不熟悉的迷宫中可以前进多远，到达那里的速度有多快。然后，我们测量了个体跟随已经训练过解决迷宫的“示威者”的倾向。在两种人群中，这两种测量结果呈正相关。这可能表明，在陌生环境中积极探索的个体可以迅速利用游行者提供的社会优势，这与害羞-大胆连续体中行为综合征的概念框架是一致的。
Individual variation in the exploration of an unfamiliar environment and joining performance probably reflects the shy-bold continuum as risk-related behavior. We experimentally examined the association between individual variation in exploration activity in an unfamiliar laboratory environment and tendency to follow other conspecifics in limnetic (primarily shoaling planktivore) and benthic (opportunistic shoaling benthic feeder) populations of three-spined stickleback from Alaska. Using a maze aquarium, we initially observed individual differences in exploration activity, that is, how far along the unfamiliar maze single immature fish could progress and how quickly they could arrive there. Then, we measured individual tendencies for individuals to follow "demonstrators" that had already been trained to solve the maze. There is a positive correlation between the 2 measurements in both populations. This may indicate that individuals active in exploration in unfamiliar environments can quickly exploit social advantages provided by demonstrators, which is consistent with the conceptual framework of behavioral syndromes in a shy-bold continuum.
