采用事件相关电位研究了刺激与反应维度重叠对部分反应激活的影响。目标刺激的可能位置（需要左或右反应）由箭头指示。为了测试自动反应激活过程是否由线索触发，计算了侧化准备电位。结果发现，反应一致的方向的线索被激活后约200毫秒的线索发作。这个早期的过程是不受特定的线索反应意外事件，并完全失踪时，非空间（颜色）线索。第二个反应激活阶段，这是部分控制的具体反应指令和主观期望。它的结论是，当刺激和反应重叠相对于空间属性，自动响应激活过程被触发，这可能会被后来所取代的预期反应的激活。
Effects of dimensional overlap between stimuli and responses on partial response activation were investigated within a priming paradigm with the help of event-related potentials. The likely position of a target stimulus (requiring a left or a right reaction) was indicated by an arrow precue. To test whether automatic response activation processes are triggered by the cue, the lateralized readiness potential was computed. It was found that responses congruent to the direction of the cue were activated about 200 ms after cue onset. This early process was unaffected by specific cue-response contingencies and was completely missing when a nonspatial (color) cue was used. A second response activation phase was observed, which was partially controlled by specific response instructions and subjective expectancies. It is concluded that when stimuli and responses overlap with respect to spatial attributes, automatic response activation process are triggered, which may later be replaced by the activation of an expected response.
