摘　　要：视觉搜索在生产生活中十分常见。本研究基于六种移动速度下的双目标视觉搜索任务对双目标动态视觉搜索模型进行探究。结果表明搜索者对双目标中的任意一个目标采取的都是随机搜索策略。研究发现现有的多目标随机搜索模型可以拓展至动态情形,但需考虑不同目标的搜索过程是否独立。在动态情况下,随着移动速度的增加,搜索第一个目标和第二个目标两个过程之间的独立性逐渐增强。Visual search has been widely applied in both everyday life and practical process. The present study explored two - target dynamic visual search model based on two - target visual search tasks with six different moving velocities. Results revealed that searchers applied random search strategy for both targets. It is demonstrated that multi - target static search model can be extended to dynamic condition. But independence of searching processes of differ- ent targets should be considered. As moving velocity increases, the independence of searching for the two targets increases in dynamic condition.
