Participants were shown rapid sequences of three letters, flanked by digits, each rotated 0 degree, 90 degrees, 180 degrees, or 270 degrees clockwise from upright. In Experiment 1, the participants tried to report the letter that matched the orientation of an arrow, presented either before (before task) or after (after task) the sequence. A third task (total task) required them to report all of the letters. Accuracy for individual letters was significantly better in the total task than in the before task, and better in the before task than in the after task, suggesting particular difficulty in binding orientation to identity. In Experiment 2, the participants were given letter probes and were asked to indicate the orientation of the probed letter. Although report was above chance, there were frequent illusory conjunctions. Since perception of orientation must depend on prior establishment of identity, our results suggest that orientation and identity may become unbound during processing and are held in parallel storage systems.
向参与者展示由数字夹着的三个字母的快速序列，每个字母相对于正立方向顺时针旋转0度、90度、180度或270度。在实验1中，参与者尝试报告与箭头方向匹配的字母，箭头在序列之前（任务前）或之后（任务后）呈现。第三个任务（总任务）要求他们报告所有字母。在总任务中，单个字母的准确率显著高于任务前，且任务前高于任务后，这表明将方向与身份进行绑定存在特别的困难。在实验2中，给参与者字母探测并要求他们指出被探测字母的方向。尽管报告高于随机水平，但仍频繁出现错觉性结合。由于方向感知必须依赖于身份的先前确立，我们的结果表明，方向和身份可能在处理过程中变得不相关联，并存储在并行存储系统中。
