六名学生（大学生和教职员）被要求区分先前学过的“标准”的棱角形状，以及随机干扰的、与标准相似度不同的“干扰物”。预先提供了有关测试表格的身份和方向的信息。学生被指示通过在心理上将指定的标准表格的内部表征（身份提示）旋转到指定的方向来准备测试表格的呈现。准备展示测试表格所需的时间随着指示方向与先前学习位置的角度偏离呈线性增加。这一发现表明，根据指示，s在准备即将到来的测试形状时进行了心理旋转。作为身份提示的标准表格的复杂程度对准备速度没有影响。判别反应时间不受测试形式复杂性和测试形式与习得取向的角度偏离的影响。此外，在辨别反应时间的模式上发现了显著的个体差异。（16 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
Six Ss (college students and staff) were required to discriminate previously learned" standard" versions of angular shapes from randomly perturbed" distractor" versions that varied in similarity to the standard. Advance information concerning the identity and the orientation of the test form was provided. Ss were instructed to prepare for the presentation of the test form by mentally rotating an internal representation of the designated standard form (identity cue) into the designated orientation. The time needed to prepare for the presentation of the test form increased linearly with the angular departure of the indicated orientation from a previously learned position. This finding suggests that, in accordance with instructions, Ss performed a mental rotation in preparing for the upcoming test shape. Rate of preparation was not affected by the complexity of the standard form presented as the identity cue. Discriminative reaction time was not affected by either test-form complexity or angular departure of the test form from the learned orientation. In addition, striking individual differences in the pattern of discriminative reaction times were found.(16 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
