The present study investigated response-response (R-R) compatibility in a bimanual keypressing task. Numeric and spatial stimuli were used to cue responses for each hand. Two groups of participants differed in terms of the stimulus-response mappings for the numeric stimuli. For one group, the numeric stimuli were mapped so that the same number for each hand indicated responses that were anatomically compatible (e.g., index finger of both hands). For the other group, the same number for each hand indicated responses that were left-right compatible (e.g., leftmost finger of both hands). The spatial stimuli were mapped in a spatially compatible manner to the responses for both groups. For numeric stimuli, reaction times (RTs) were faster when the same number indicated the response for each hand, regardless of the mapping. For the spatial stimuli, RTs were determined not only by the pairing of stimuli or responses, but also by how the responses were indicated by numeric stimuli. The results indicate that R-R compatibility effects are mediated by abstract codes that reflect individuals' conceptualizations of their actions.
本研究在双手按键任务中探究了反应-反应（R-R）兼容性。使用数字和空间刺激来提示每只手的反应。两组参与者在数字刺激的刺激-反应映射方面存在差异。对于一组参与者，数字刺激的映射方式是，每只手相同的数字表示在解剖学上兼容的反应（例如，双手的食指）。对于另一组参与者，每只手相同的数字表示左右兼容的反应（例如，双手最左边的手指）。空间刺激以空间兼容的方式映射到两组的反应上。对于数字刺激，无论映射方式如何，当相同数字表示每只手的反应时，反应时间（RTs）更快。对于空间刺激，反应时间不仅取决于刺激或反应的配对，还取决于数字刺激如何指示反应。结果表明，R-R兼容性效应是由反映个体对其动作概念化的抽象代码介导的。
