Abstract

Inhibition of return (IOR) is reflected as a slower manual or saccadic response to a cued rather than an uncued target (manual IOR and saccadic IOR, respectively), and as a pupillary dilation when a bright, relative to a dark side of a display is cued (pupillary IOR). The aim of this study was to investigate the relation between an IOR and oculomotor system. According to the predominant view, only the saccadic IOR is strictly related to the visuomotor process, and the manual and pupillary IORs depend on non-motor factors (e.g., short-term visual depression). Alternatively, the after-effect of the covert-orienting hypothesis postulates that IOR is strictly related to the oculomotor system. As fixation offset affects oculomotor processes, this study investigated whether fixation offset also affects pupillary and manual IORs. The results show that fixation offset decreased IOR in pupillary but not manual responses, and provides support for the hypothesis that at least the pupillary IOR is tightly linked to eye movement preparation.

固定偏移减少瞳孔抑制返回

返回抑制（IOR）反映为对提示而非未提示目标的较慢的手动或扫视反应（分别为手动IOR和扫视IOR），以及当显示的亮面相对于暗面被提示时瞳孔扩张（瞳孔IOR）。本研究的目的是研究IOR与动眼器系统之间的关系。根据主流观点，只有扫视IOR与视运动过程密切相关，而手动和瞳孔IOR取决于非运动因素（如短期视觉抑郁）。或者，隐蔽定向假说的后效应假设IOR与动眼器系统密切相关。由于固定偏移影响眼球运动过程，本研究调查了固定偏移是否也影响瞳孔和手动IOR。结果表明，固定偏移降低了瞳孔IOR，但没有降低手动反应，并为至少瞳孔IOR与眼动准备密切相关的假设提供了支持。

期刊介绍： Brain and Cognition is a forum for the integration of the neurosciences and cognitive sciences. B&C publishes peer-reviewed research articles, theoretical papers, case histories that address important theoretical issues, and historical articles into the interaction between cognitive function and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in cognition. Coverage includes, but is not limited to memory, learning, emotion, perception, movement, music or praxis in relationship to brain structure or function. Published articles will typically address issues relating some aspect of cognitive function to its neurological substrates with clear theoretical import, formulating new hypotheses or refuting previously established hypotheses. Clinical papers are welcome if they raise issues of theoretical importance or concern and shed light on the interaction between brain function and cognitive function. We welcome review articles that clearly contribute a new perspective or integration, beyond summarizing the literature in the field; authors of review articles should make explicit where the contribution lies. We also welcome proposals for special issues on aspects of the relation between cognition and the structure and function of the nervous system. Such proposals can be made directly to the Editor-in-Chief from individuals interested in being guest editors for such collections.
