在眼球运动到最近注视的位置之前，眼跳潜伏期比控制位置更长，这种现象称为眼球返回抑制（O-IOR）。理论上有理由认为O-IOR在不同的眼动任务中会有不同的大小，但以前的研究产生了相互矛盾的证据。然而，这可能是因为以前的研究没有分离O-IOR和相关的现象，眼跳动量，这是一个偏见，重复眼跳程序，也影响眼跳延迟。本研究分离了O-IOR和扫视动量在三个复杂视觉任务中的影响：场景搜索、场景记忆和场景审美偏好。O-IOR在所有三个任务中的大小相似，而扫视动量在场景搜索中较弱。
Saccade latencies are longer prior to an eye movement to a recently fixated location than to control locations, a phenomenon known as oculomotor inhibition of return (O-IOR). There are theoretical reasons to expect that O-IOR would vary in magnitude across different eye movement tasks, but previous studies have produced contradictory evidence. However, this may have been because previous studies have not dissociated O-IOR and a related phenomenon, saccadic momentum, which is a bias to repeat saccade programs that also influences saccade latencies. The present study dissociated the influence of O-IOR and saccadic momentum across three complex visual tasks: scene search, scene memorization, and scene aesthetic preference. O-IOR was of similar magnitude across all three tasks, while saccadic momentum was weaker in scene search.
