Through stimulus-response compatibility we tested whether sound frequency (pitch height) elicits a mental spatial representation. Musically untrained and, mostly, trained participants were shown a stimulus-response compatibility effect (Spatial-Musical Association of Response Codes or SMARC effect). When response alternatives were either vertically or horizontally aligned, performance was better when the lower (or leftward) button had to be pressed in response to a low sound and the upper (or rightward) button had to be pressed in response to a high sound, even when pitch height was irrelevant to the task.
通过刺激-反应兼容性，我们测试了声音频率（音高）是否会引发心理空间表征。我们向未受过音乐训练以及大多受过训练的参与者展示了一种刺激-反应兼容性效应（反应编码的空间-音乐关联效应或SMARC效应）。当反应选项垂直或水平排列时，若要求参与者在听到低音时按下下方（或向左）按钮，听到高音时按下上方（或向右）按钮，即使音高与任务无关，他们的表现也会更好。
