当上下刺激映射到左右反应时，发现一种上下映射优势，这种优势被反应偏心率和手的姿势所改变。这些效应可归因于相对于多个参照系形成的非对称刺激和反应编码的对应性。我们研究了刺激设置位置对这些正交刺激-反应相容性（SRC）效应的影响。在实验1中，刺激集出现在上或下显示位置。形成刺激集合位置的空间编码，产生西蒙型反应偏心率和手姿效应，但该编码对相关刺激的编码没有影响。在实验2中，刺激集相对于反应位置分别出现在左、中、右三个位置，这些位置也会发生变化，以分离反应位置、相对于刺激显示和身体中线的影响。前者影响单手开关运动和双手按键的正交SRC效应，后者仅影响单手开关运动的正交SRC效应。刺激集位置沿刺激维度变化时产生正交simon型效应，沿反应维度变化时为反应编码提供参照。
When up-down stimuli are mapped to left-right responses, an up-right/down-left mapping advantage is found that is modified by response eccentricity and hand posture. These effects can be attributed to correspondence of asymmetric stimulus and response codes formed relative to multiple reference frames. We examined the influence of stimulus-set location on these orthogonal stimulus-response compatibility (SRC) effects. In Experiment 1, the stimulus set appeared in the upper or lower display positions. A spatial code for stimulus-set location was formed, producing Simon-type response eccentricity and hand posture effects, but this code had no influence on the coding of the relevant stimuli. In Experiment 2, the stimulus set appeared in the left, center, or right positions relative to the response location, which also varied, to dissociate the effects of response location, relative to the stimulus display and body midline. The former factor influenced the orthogonal SRC effect for both unimanual switch movements and bimanual keypresses, and the latter factor influenced the effect for only unimanual switch movements. Stimulus-set location causes orthogonal Simon-type effects when varied along the stimulus dimension and provides a referent for response coding when varied along the response dimension.
