Imaginal perspective switches are often considered to be difficult, because they call for additional cognitive transformations of object coordinates (transformation hypothesis). Recent research suggests that problems can also result from conflicts between incompatible sensorimotor and cognitive object location codes during response specification and selection (interference hypothesis). Three experiments tested contrasting predictions of both accounts. Volunteers had to point to unseen object locations after imagined self-rotations and self-translations. Results revealed larger pointing latencies and errors for rotations as compared to translations, and monotic latency and error increases for both tasks as a function of the disparity of object directions between real and imagined perspective. Provision of advance information about the to-be-imagined perspective left both effects unchanged. These results, together with those from a systematic error analysis, deliver clear support for an interference account of imaginal perspective switches in remembered surroundings.

记忆环境中的想象视角切换：转换与干扰帐户

想象视角切换通常被认为是困难的，因为它们需要对物体坐标进行额外的认知变换（变换假设）。最近的研究表明，在响应规范和选择（干扰假设）期间，不兼容的感觉运动和认知对象位置代码之间的冲突也可能导致问题。三个实验测试了两个帐户的对比预测。在想象中的自我旋转和自我翻译之后，志愿者不得不指向看不见的物体位置。结果显示，与平移相比，旋转的指向延迟和误差更大，并且这两项任务的单调延迟和误差都随着真实视角和想象视角之间的对象方向差异而增加。提供关于将要想象的视角的预先信息使这两种效果保持不变。这些结果，连同来自系统误差分析的结果，为记忆环境中想象视角切换的干扰解释提供了明确的支持。
