This study investigated the compatibility of stimulus codes and response modalities and how it mediated the spatial Stroop effect. Stimulus code (word, arrow and moving dots), response modality (voice, keypress and mouse movement), directional information (left and right) and physical location (centre, left and right) of the stimulus were manipulated. Participants responded to the directional information of the stimulus. Spatial interference was expected when the stimulus' directional information and physical location were incongruent. Results showed that more compatible pairings for the three response modalities were word-voice, arrow-keypress and arrow-movement. Incongruent spatial location delayed the reaction time for all response modalities with the word, speeded up the vocal and keypress responses with the moving dots, and had no effect with the arrow. Arrow was thus recommended for conveying directional information on interfaces. This study demonstrated that spatial interference was mediated by the stimulus code, response modality and their compatibility.
This study manipulated three stimulus codes and three response modalities to examine how stimulus–response compatibility mediated the spatial Stroop effect. Spatial interference appeared with the word and moving dots, but not arrow stimulus, for vocal, keypress and mouse responses. Arrow was therefore recommended to convey directional information on an interface.
本研究调查了刺激代码与反应方式的兼容性，以及它如何介导空间斯特鲁普效应。对刺激的代码（单词、箭头和移动点）、反应方式（语音、按键和鼠标移动）、方向信息（左和右）以及刺激的物理位置（中心、左和右）进行了操控。参与者对刺激的方向信息做出反应。当刺激的方向信息与物理位置不一致时，预计会出现空间干扰。结果表明，三种反应方式中更兼容的配对是单词-语音、箭头-按键和箭头-移动。不一致的空间位置延迟了所有对单词的反应方式的反应时间，加快了对移动点的语音和按键反应，而对箭头则没有影响。因此，建议使用箭头在界面上传达方向信息。本研究表明，空间干扰是由刺激代码、反应方式及其兼容性介导的。
