在即时记忆任务中，当被试被要求以相反的顺序回忆列表项目时，与更典型的前向回忆相比，基准记忆现象并不一致。这些不一致性已被归因于更大的参与视觉空间表征在向后比向前回忆在检索点。在本研究中，我们测试了这一假设与双任务范式中，手动空间敲击和动态视觉噪声被用作干扰任务。干扰任务是在列表呈现或回忆时进行的。在前四个实验中，回忆方向只在回忆时传达。在实验1和2中，较少的话回忆与手动轻敲比在控制条件。然而，手动敲击的有害影响并没有随着回忆方向或处理阶段的变化而变化。在实验3中，动态视觉噪声不影响回忆成绩。在实验4中，发音抑制进行了所有的审判和手动轻敲他们的一半。与前两个实验一样，手动敲击在相同程度上对向前和向后回忆产生了争议。在实验5中，回忆方向是已知的列表呈现之前。正如视觉空间假说所预测的那样，当在回忆过程中进行手动敲击时，其有害影响仅限于向后回忆。总的来说，结果可以通过调用一个修改后的版本的视觉空间假说来解释。
In an immediate memory task, when participants are asked to recall list items in reverse order, benchmark memory phenomena found with more typical forward recall are not consistently reproduced. These inconsistencies have been attributed to the greater involvement of visuospatial representations in backward than in forward recall at the point of retrieval. In the present study, we tested this hypothesis with a dual-task paradigm in which manual-spatial tapping and dynamic visual noise were used as the interfering tasks. The interference task was performed during list presentation or at recall. In the first four experiments, recall direction was only communicated at the point of recall. In Experiments 1 and 2, fewer words were recalled with manual tapping than in the control condition. However, the detrimental effect of manual tapping did not vary as a function of recall direction or processing stage. In Experiment 3, dynamic visual noise did not influence recall performance. In Experiment 4, articulatory suppression was performed on all trials and manual tapping was added on half of them. As in the first two experiments, manual tapping disputed forward and backward recall to the same extent. In Experiment 5, recall direction was known before list presentation. As predicted by the visuospatial hypothesis, when manual tapping was performed during recall, its detrimental effect was limited to backward recall. Overall, results can be explained by calling upon a modified version of the visuospatial hypothesis.
