In the current study, we investigated whether the introduction of perspective shifts in a spatial memory task results in systematic biases in object location estimations. To do so, we asked participants to first encode the position of an object in a virtual room and then to report its position from memory or perception following a perspective shift. Overall, our results showed that participants made systematic errors in estimating object positions in the same direction as the perspective shift. Notably, this bias was present in both memory and perception conditions. We propose that the observed systematic bias was driven by difficulties in understanding the perspective shifts that led participants to use an egocentric representation of object positions as an anchor when estimating the object location following a perspective shift.
在当前的研究中，我们调查了在空间记忆任务中引入视角转换是否会导致物体位置估计的系统偏差。为此，我们要求参与者首先在虚拟房间中对一个物体的位置进行编码，然后在视角转换后通过记忆或感知来报告其位置。总的来说，我们的结果表明，参与者在估计与视角转换方向相同的物体位置时会产生系统性误差。值得注意的是，这种偏差在记忆和感知条件下都存在。我们提出，观察到的系统性偏差是由理解视角转换的困难所驱动的，这导致参与者在视角转换后估计物体位置时使用以自我为中心的物体位置表示作为锚点。
