这项任务切换ERP研究的16名年轻参与者调查是否增加RT减慢停留试验和更快的RT切换试验频繁比不频繁切换解释了激活或准备帐户。激活帐户提出，任务集保持在一个较高的基线激活水平频繁切换，需要增加任务集更新，反映了一个更大的和/或更长的持续早期顶叶积极。准备帐户假定提前（预提示）切换准备（即，任务集重新配置），前停留和开关试验频繁切换，反映了前线索和后线索晚顶叶积极。总的来说，数据支持激活帐户。然而，我们也发现增加，前线索任务集更新频繁停留试验和前线索，任务集重新配置之前，可预测的，频繁的开关。这些结果使我们提出了一个扩展的激活帐户，以解释转换概率的执行过程的任务转换行为的影响。
This task-switching ERP study of 16 young participants investigated whether increased RT slowing on stay trials and faster RTs on switch trials for frequent than infrequent switching are explained by an activation or preparation account. The activation account proposes that task sets are maintained at a higher baseline activation level for frequent switching, necessitating increased task-set updating, as reflected by a larger and/or longer lasting early parietal positivity. The preparation account assumes advance (pre-cue) switch preparation (i.e., task-set reconfiguration), preceding stay and switch trials for frequent switching, as reflected by pre-cue and post-cue late parietal positivities. By and large, the data support the activation account. However, we also found increased, pre-cue task-set updating on frequent stay trials and pre-cue, task-set reconfiguration prior to predictable, frequent switches. These results lead us to propose an extended activation account to explain the effects of switch probability on the executive processes underlying task-switching behavior.
