In two experiments, we tested whether the emergence of the go/no-go Simon effect could be determined by the strengthening of one specific S-R link in location-relevant trials performed right before (practice paradigm) or simultaneously (mixing paradigm) with the location-irrelevant (Simon) trials. Results showed a clear carry-over effect of the association between stimulus position and spatial response from the first task to the second one (Experiment 1) and when the two tasks were performed simultaneously (Experiment 2), even if participants were required to respond with the same key to only half of the stimuli (go/no-go tasks). We found that associative learning between the stimulus and response positions occurring during the go/no-go compatibility task, that is when location was relevant, influenced the way the go/no-go location-irrelevant task (Simon task) was performed. Our findings suggest that the STM links formed during a go/no-go spatial compatibility task are strong enough to influence the go/no-go Simon task.
在两项实验中，我们测试了对特定刺激做出反应（Go/No-Go）的西蒙效应的出现，是否可以通过在与位置无关（西蒙）试验之前（练习范式）或同时（混合范式）进行的与位置相关试验中加强一个特定的刺激-反应（S-R）联系来确定。结果显示，从第一个任务到第二个任务（实验1），以及当两个任务同时进行时（实验2），刺激位置与空间反应之间的关联存在明显的延续效应，即使要求参与者仅对一半的刺激（对特定刺激做出反应任务）使用相同的按键做出反应。我们发现，在对特定刺激做出反应的兼容性任务中，即当位置相关时，刺激与反应位置之间的联想学习，会影响对特定刺激做出反应的位置无关任务（西蒙任务）的执行方式。我们的研究结果表明，在对特定刺激做出反应的空间兼容性任务中形成的短时记忆联系，足以影响对特定刺激做出反应的西蒙任务。
