垂直刺激和水平反应的右上/左下映射优势被称为正交刺激-反应相容(SRC)效应。我们考察了与刺激维度无关的正交性SRC效应是否出现。在实验1中，参与者对呈现在注视上方或下方的刺激颜色进行了向右或向左按键的反应。我们观察到了右上/左下的优势(正交西蒙效应)。在实验2中，我们通过改变反应集的水平位置来操纵反应维度中的极性。随着左反应编码变得更积极，正交西蒙效应减弱，甚至反转。这一结果为积极和消极反应代码被相应的积极和消极刺激代码自动激活提供了证据。这些发现将基于编码不对称的正交SRC效应扩展到无关的刺激维度。
The above-right/below-left mapping advantage with vertical stimuli and horizontal responses is known as the orthogonal stimulus–response compatibility (SRC) effect. We investigated whether the orthogonal SRC effect emerges with irrelevant stimulus dimensions. In Experiment 1, participants responded with a right or left key press to the colour of the stimulus presented above or below the fixation. We observed an above-right/below-left advantage (orthogonal Simon effect). In Experiment 2, we manipulated the polarity in the response dimension by varying the horizontal location of the response set. The orthogonal Simon effect decreased and even reversed as the left response code became more positive. This result provides evidence for the automatic activation of the positive and negative response codes by the corresponding positive and negative stimulus codes. These findings extended the orthogonal SRC effect based on coding asymmetry to an irrelevant stimulus dimension.
