设计了二维西蒙型任务来研究任务要求和显式指令对空间动作编码的影响。受试者执行在两个空间维度上定义的动作：水平（左右）或垂直（上下）。相关的刺激特征是非空间的，但刺激在水平和垂直维度上有所不同，因此可以分别测量水平和垂直的S-R兼容性效应。通过让受试者在西蒙任务之前执行一项不相关的任务来操纵隐性任务要求——该任务中只有两个空间维度之一相关。通过用空间术语描述不相关的启动任务和/或西蒙任务中的响应或通过参考响应键的非空间特征来改变指令。启动特定维度会增加该维度的西蒙效应，而指令则没有差异效应。这些发现表明，首先，将注意力吸引到特定维度会对该维度上定义的那些特征（有意加权）的事件表示做出更大的贡献，其次，如果操作不改变任务目标，则指令不会影响动作编码。
A two-dimensional Simon-type task was devised to investigate the impact of task requirements and explicit instructions on spatial action coding. Subjects performed actions that were defined on two spatial dimensions: horizontal (left-right) or vertical (top-bottom). The relevant stimulus feature was nonspatial but the stimuli varied on the horizontal and the vertical dimension, so that horizontal and vertical S-R compatibility effects could be measured separately. Implicit task requirements were manipulated by having the subjects perform an unrelated task before the Simon task—a task in which only one of the two spatial dimensions was relevant. Instructions were varied by describing the responses in the unrelated priming task and/or in the Simon task in spatial terms or by referring to nonspatial features of the response keys. Priming a particular dimension increased the Simon effect on that dimension, whereas instructions had no differential effect. These findings suggest that, first, drawing attention to a particular dimension leads to a stronger contribution to event representation of those features defined on that dimension (intentional weighting) and, second, that instructions do not affect action coding if the manipulation does not change the task goal.
