There has been growing interest in exploring human performance for situations in which stimuli and/or responses vary along both horizontal and vertical dimensions. Earlier studies indicated that there is a prevalence of the horizontal dimension over the vertical dimension in the spatial codes that are used for response selection. We review evidence about spatial coding for 2-D stimulus-response sets and accounts that have been proposed for explaining how it takes place. Particular attention is devoted to the relative salience account, which provides the most comprehensive explanation of 2-D spatial coding. We also evaluate the influence of speed of spatial code formation, number of reference frames, and learning on subjects' performance in 2-D tasks.
对于刺激和/或反应在水平和垂直维度上都有所变化的情况，人们对探索人类表现的兴趣与日俱增。早期研究表明，在用于反应选择的空间编码中，水平维度比垂直维度更为普遍。我们回顾了关于二维刺激-反应集空间编码的证据，以及为解释其发生方式而提出的各种理论。我们特别关注相对显著性理论，它对二维空间编码提供了最全面的解释。我们还评估了空间编码形成速度、参考框架数量和学习对受试者在二维任务中表现的影响。
