Abstract
In order to maintain stability across saccades, the visual system must keep track of nonspatial information bound to each location (object-location binding). Here, we investigated whether saccade target status affects the reference frame of trans-saccadic object-location binding. Previous studies examining the reference frame of object-location binding showed that peripheral, nonsaccade target objects are naturally bound to retinotopic, not spatiotopic, coordinates. But real-world saccades are generally directed toward objects of interest: Might trans-saccadic object-location binding occur in more ecologically relevant spatiotopic coordinates for saccade target objects? We adopted a modified spatial congruency bias paradigm, in which participants were asked to judge if two objects have the same or different identity. A saccade between object presentations was directed either toward the first object's location (saccade target condition) or to another location (saccade-elsewhere and saccade-away conditions). Across three preregistered experiments, we found primarily retinotopic object-location binding in the saccade-elsewhere and saccade-away conditions, but coexisting spatiotopic and retinotopic binding in the saccade target condition. The results indicate that saccade target objects can be additionally bound to spatiotopic coordinates across saccades and that it is the saccade target status specifically that allows an object to be additionally bound to spatiotopic coordinates. Overall, these findings highlight the importance of saccade target objects in maintaining stability across saccades, allowing for object-location binding to be encoded and/or remapped in stable spatiotopic coordinates.

为了保持囊回的稳定性,视觉系统必须跟踪与每个位置绑定的非空间信息(物体-位置绑定)。在此,我们研究了囊状移动的目标状态是否会影响跨囊状移动物体位置绑定的参照框架。之前对物体位置绑定参考框架的研究表明,外围的非囊回目标物体会自然地绑定在视网膜坐标上,而不是空间坐标上。但现实世界中的囊回通常是指向感兴趣的物体:对于囊回目标对象来说,跨囊回对象定位绑定是否会发生在与生态学更相关的空间坐标上?我们采用了一种改良的空间一致性偏差范式,要求参与者判断两个物体的身份是相同还是不同。对象呈现之间的囊回要么指向第一个对象的位置(囊回目标条件),要么指向另一个位置(囊回别处条件和囊回远离条件)。在三项预先登记的实验中,我们发现在囊走到别处和囊走到别处条件下,主要是视网膜视位的物体位置结合,但在囊走目标条件下,同时存在空间视位和视网膜视位结合。这些结果表明,囊闪目标对象可以在整个囊闪过程中与空间坐标额外结合,而正是囊闪目标状态使对象与空间坐标额外结合。总之,这些发现强调了囊状移动目标对象在保持囊状移动稳定性方面的重要性,从而使对象位置绑定可以在稳定的空间坐标中编码和/或重新映射。(PsycInfo Database Record (c) 2025 APA, all rights reserved)。
期刊介绍:
The Journal of Experimental Psychology: General publishes articles describing empirical work that bridges the traditional interests of two or more communities of psychology. The work may touch on issues dealt with in JEP: Learning, Memory, and Cognition, JEP: Human Perception and Performance, JEP: Animal Behavior Processes, or JEP: Applied, but may also concern issues in other subdisciplines of psychology, including social processes, developmental processes, psychopathology, neuroscience, or computational modeling. Articles in JEP: General may be longer than the usual journal publication if necessary, but shorter articles that bridge subdisciplines will also be considered.
