In everyday life, we continuously search for and classify objects in the environment around us. This kind of visual search is extremely important when performed by radiologists in cancer image interpretation and officers in airport security screening. During these tasks, observers often examine large numbers of uncorrelated images (tumor x-rays, checkpoint x-rays, etc.) one after another. An underlying assumption of such tasks is that search and recognition are independent of our past experience. Here, we simulated a visual search task reminiscent of medical image search and found that shape classification performance was strongly impaired by recent visual experience, biasing classification errors 7% more towards the previous image content. This perceptual attraction exhibited the three main tuning characteristics of Continuity Fields: serial dependence extended over 12 seconds back in time (temporal tuning), it occurred only between similar tumor-like shapes (feature tuning), and only within a limited spatial region (spatial tuning). Taken together, these results demonstrate that serial dependence influences shape perception and occurs in visual search tasks. They also raise the possibility of a detrimental impact of serial dependence in clinical and practically relevant settings, such as medical image perception.

模拟临床视觉搜索任务中的串行依赖性。
在日常生活中,我们不断地寻找周围环境中的物体并对其进行分类。当放射科医师进行癌症图像判读和官员进行机场安检时,这种视觉搜索极其重要。在这些任务中,观察者经常依次检查大量不相关的图像(肿瘤 X 射线、检查点 X 射线等)。此类任务的基本假设是搜索和识别独立于我们过去的经验。在这里,我们模拟了一个让人想起医学图像搜索的视觉搜索任务,发现最近的视觉体验严重损害了形状分类性能,使分类错误更偏向于先前的图像内容 7%。这种感知吸引力展现了连续性场的三个主要调谐特征:序列依赖性在时间上延伸超过12秒(时间调谐),仅发生在相似的肿瘤状形状之间(特征调谐),并且仅发生在有限的空间区域内(空间调谐)。调)。总而言之,这些结果表明序列依赖性影响形状感知并发生在视觉搜索任务中。它们还提出了序列依赖性在临床和实际相关环境(例如医学图像感知)中产生不利影响的可能性。
