在觅食群体中，个体可以利用来自社会环境的信息来帮助决策，选择在哪里寻找食物。很少有研究关注行为差异的成本或收益，例如在学习能力方面，大胆程度的个体差异。在这里，我们调查的反应，三刺鱼（Gasterosteus aculeatus）觅食任务期间的“社会线索”，“本地增强”和“公共信息”。我们的研究结果证实了以前的工作表明，这一物种的社会线索和本地增强，但不是公共信息。在大胆的变化并不影响使用不同类型的信息。然而，做出选择和到达一个补丁所需的时间在不同大胆程度的鱼之间存在差异。与预期相反，害羞的鱼是更多变的个体，在响应任务时具有更大的反应时间范围。这表明，在利用从环境中获得的信息时，个人行为差异仍然发挥作用，并可能影响在不同情况下可能产生的相对效益。
In foraging groups, individuals may utilise information from their social environment to aid decision making when choosing where to search for food. Little work has looked at the costs or benefits of behavioural differences, such as consistent individual variation in boldness, with respect to learning ability. Here, we investigate the response of three-spined stickleback (Gasterosteus aculeatus) to 'social cues', 'local enhancement' and 'public information' during foraging tasks. Our results confirm previous work suggesting that this species responds to social cues and local enhancement but not public information. Variation in boldness did not affect the use of different types of information. However, time taken to make a choice and reach a patch varied between fish with different levels of boldness. Contrary to expectation, shy fish were the more variable individuals, having a greater range of reaction times when responding to the tasks. This suggests that individual behavioural differences still play a role when utilising information obtained from the environment and may influence the relative benefits that could result in different contexts.
