先前的研究表明，记忆中的到达目标是相对于凝视进行编码和更新的，至少在目标熄灭后不久进行到达动作时是这样。在本研究中，我们想要测试不同时间延迟后到达目标是否相对于凝视进行更新。无论动作是立即执行还是在延迟 5 秒、8 秒或 12 秒后执行，到达终点都会随着相对于目标的注视而系统地变化。目前的结果表明，如果不存在外部线索，到达目标的记忆痕迹将继续在依赖于凝视的参考系中进行编码。 (C) 2011 Elsevier Ltd. 保留所有权利。
Previous research has demonstrated that remembered targets for reaching are coded and updated relative to gaze, at least when the reaching movement is made soon after the target has been extinguished. In this study, we want to test whether reach targets are updated relative to gaze following different time delays. Reaching endpoints systematically varied as a function of gaze relative to target irrespective of whether the action was executed immediately or after a delay of 5 s, 8 s or 12 s. The present results suggest that memory traces for reach targets continue to be coded in a gaze-dependent reference frame if no external cues are present. (C) 2011 Elsevier Ltd. All rights reserved.
