四个反应时实验采用心理不应期范式考察心理旋转过程。在每次试验中，参与者对音调（S）和旋转字母（S）做出快速反应，并呈现不同的刺激起始时间（SOA）。如果刺激字母的心理旋转可以在中枢机制忙碌忙于处理S刺激时进行，那么方向的影响应该随着SOA的降低而大大降低。与这些预测相反，方向的影响在SOA中几乎是恒定的，这表明如果没有中枢机制的帮助，心理旋转就不能有效地进行。这些结果支持的结论是，心理旋转需要访问一个单通道的机制，因此必须与其他操作需要相同的机制串行执行。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Four reaction time experiments examined the mental rotation process using a psychological refractory period paradigm. On each trial, participants made speeded responses to both a tone (S₁) and a rotated letter (S₂), presented with varying stimulus onset asynchronies (SOAs). If mental rotation of the stimulus letter can proceed while central mechanisms are busy with S₁, then the effect of orientation should decrease substantially with decreasing SOA. Contrary to these predictions, the effect of orientation was nearly constant across SOAs, suggesting that mental rotation cannot effectively proceed without help from central mechanisms. These results support the conclusion that mental rotation requires access to a single-channel mechanism and must therefore be performed serially with other operations requiring the same mechanism.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
