A striking range of individual differences has recently been reported in three different visual search tasks. These differences in performance can be attributed to strategy, that is, the efficiency with which participants control their search to complete the task quickly and accurately. Here, we ask whether an individual's strategy and performance in one search task is correlated with how they perform in the other two. We tested 64 observers and found that even though the test-retest reliability of the tasks was high, an observer's performance and strategy in one task was not predictive of their behaviour in the other two. These results suggest search strategies are stable over time, but context-specific. To understand visual search, we therefore need to account not only for differences between individuals but also how individuals interact with the search task and context.
最近在三个不同的视觉搜索任务中报告了一系列引人注目的个体差异。这些表现上的差异可以归因于策略，即参与者控制搜索以快速准确地完成任务的效率。在这里，我们想问的是，一个人在一个搜索任务中的策略和表现是否与他们在另外两个任务中的表现相关。我们测试了 64 名观察者，发现尽管任务的测试-再测试可靠性很高，但一个人在一个任务中的表现和策略并不能预测他们在另外两个任务中的行为。这些结果表明搜索策略是稳定的，但具有特定于上下文的特征。因此，要理解视觉搜索，我们不仅需要考虑个体之间的差异，还需要考虑个体如何与搜索任务和上下文相互作用。
