这项研究探讨了大胆是否可以用来预测社会地位。首先，通过监测个体斑马鱼在以下环境中的行为来评估大胆性：（1）没有遮蔽物的不熟悉的贫瘠环境（开阔地），（2）引入屋顶作为遮蔽物时的相同环境，以及（3）移除屋顶并引入不熟悉的物体（乐高砖）时。接下来，经过至少一周的休息期，鱼的社会地位确定在一个二元的比赛和主导/从属个人被确定为两个连续的比赛的赢家/输家。多变量数据分析表明，男性比女性更大胆，大胆的测试过程中所表达的鱼的行为可以用来预测鱼将成为主导和从属在随后的二元竞争。我们的结论是，大胆的行为是正相关的优势，在斑马鱼和大胆并不仅仅是社会优势的后果。
This study explored if boldness could be used to predict social status. First, boldness was assessed by monitoring individual zebrafish behaviour in (1) an unfamiliar barren environment with no shelter (open field), (2) the same environment when a roof was introduced as a shelter, and (3) when the roof was removed and an unfamiliar object (Lego (R) brick) was introduced. Next, after a resting period of minimum one week, social status of the fish was determined in a dyadic contest and dominant/subordinate individuals were determined as the winner/loser of two consecutive contests. Multivariate data analyses showed that males were bolder than females and that the behaviours expressed by the fish during the boldness tests could be used to predict which fish would later become dominant and subordinate in the ensuing dyadic contest. We conclude that bold behaviour is positively correlated to dominance in zebrafish and that boldness is not solely a consequence of social dominance.
