Two experiments were conducted to assess whether the joint Simon effect is composed of facilitation and interference and whether facilitation is increased by a joint spatially compatible practice performed before performing the joint Simon task. In both experiments, participants were required to perform a Simon task along another person. Trials could be corresponding, non-corresponding, and neutral. In Experiment 1, participants performed only the Simon task. In Experiment 2, participants first practiced on a joint spatial compatibility task with a compatible mapping and, after a 5-min delay, transferred to a joint Simon task. Results indicated that the joint Simon effect consisted primarily of interference, which was significantly increased by a spatially compatible practice performed jointly. These results allow us to better define in what ways the presence of the other influences performance, in showing that when participants perform a task along with another individual, they display a disadvantage (i.e., slower RTs) when they have to respond to stimuli appearing on the other agent's side.
进行了两项实验来评估联合西蒙效应是否由促进和干扰组成，以及在执行联合西蒙任务之前进行联合空间相容练习是否会增加促进作用。在这两项实验中，参与者都需要与另一个人一起执行西蒙任务。试验可以是对应、不对应和中性的。在实验 1 中，参与者仅执行西蒙任务。在实验 2 中，参与者首先在具有相容映射的联合空间相容性任务上进行练习，然后在 5 分钟的延迟后转移到联合西蒙任务上。结果表明，联合西蒙效应主要由干扰组成，通过联合执行空间相容练习，干扰显著增加。这些结果使我们能够更好地定义另一个人以何种方式影响表现，表明当参与者与另一个人一起执行任务时，当他们必须对另一个参与者的一侧出现的刺激做出反应时，他们会处于劣势（即反应时间较慢）。
