最近人们对公共信息的使用以及动物性格的进化起源和生态后果产生了很大的兴趣，但令人惊讶的是这两个领域的整合很少。人格特质可能会影响个人以多种不同方式对公共信息做出反应的程度。作为解决其中一些问题的第一步，在本研究中，我们询问人格特征是否可以预测九刺棘鱼（Pungitius pungitius）的公共信息使用。在 33 天的时间里，受试者的多项行为特征（包括活动、探索和成群倾向的测量）被进行了两次评分，并多次接受公共信息使用觅食任务，其中要求他们根据两个示范组的觅食成功情况选择两个猎物斑块中较丰富的一个。可重复的（r= 0.38–0.58）行为特征被简化为描述空间使用和社交性的两个主要组成部分。发现这些都与公共信息使用的两项措施中的任何一项无关。虽然我们认为的人格特征与该物种的公共信息使用并不共同变化，但它们很可能间接影响接触公共信息的机会，这是进一步研究的明显途径。
There has been much recent interest in both public information use, and the evolutionary origins and ecological consequences of animal personalities but surprisingly little integration of these two fields. Personality traits may impact upon the extent to which individuals respond to public information in a number of different ways. As a first step towards addressing some of these questions, in this study, we asked whether personality traits predicted public information use in ninespine sticklebacks (Pungitius pungitius). Over a 33-day period, subjects were scored twice for a number of behavioural traits, including measures of activity, exploration and shoaling tendency, and were exposed multiple times to a public information use foraging task, in which they were required to select the richer of two prey patches based upon the foraging success of two demonstrator groups. The repeatable (r= 0.38–0.58) behavioural traits were reduced to two principle components describing space use and sociability. Neither of these was found to be related to either of two measures of public information use. While the personality traits that we considered did not co-vary with public information use in this species, they may well indirectly affect opportunity for exposure to public information, and this is an obvious avenue for further research.
