This study cross-validates reported changes in behavioural and event-related potential (ERP) correlates of prospective memory (PM) inhibitory control performance applying different PM response selection demands (Bisiacchi et al., 2009). Participants were randomly assigned to a control group condition with no PM requirement, or to either inhibit ongoing task processing to respond to PM task cues (task-switch; TS) or provide an ongoing task response prior to providing a PM button press (dual-task; DT). The behavioural data indicated that ongoing task reaction time (RT) performance was similar in the DT, TS, and control group conditions. PM cue detection mechanisms reflected by the N300 did not differ between PM tasks. However, early occurring (400–700 ms) PM late parietal complex (LPC) amplitudes recorded over anterior electrode sites were larger in the TS compared to the DT-PM condition, and this difference persisted during the 700–1000 ms epoch. Thus, ERP correlates of PM task-set remapping were significantly altered via the induction of different PM response production rules retrieved from retrospective memory (RM). The enhancement of anteriorly distributed TS LPC amplitudes between 400 and 700 ms led to the suggestion that increased inhibition in this group condition was accompanied by heightened frontally mediated neural activations that support prepotent ongoing task response inhibition processing.

前瞻记忆中的​​抑制控制:任务切换和双任务处理的事件相关电位比较

这项研究交叉验证了应用不同 PM 响应选择要求的前瞻记忆 (PM) 抑制控制性能的行为和事件相关电位 (ERP) 相关性的变化(Bisiacchi 等,2009)。参与者被随机分配到一个没有 PM 要求的对照组条件,或者抑制正在进行的任务处理以响应 PM 任务提示(任务切换;TS)或在提供 PM 按钮按下之前提供正在进行的任务响应(双-任务;DT)。行为数据表明,持续任务反应时间 (RT) 表现在 DT、TS 和对照组条件下相似。N300 反映的 PM 提示检测机制在 PM 任务之间没有差异。然而,与 DT-PM 条件相比,在前电极部位记录的早期(400-700 ms)PM 晚期顶叶复合体(LPC)振幅在 TS 中更大,并且这种差异在 700-1000 ms 时期持续存在。因此,通过从回顾性记忆 (RM) 中检索到的不同 PM 响应产生规则的诱导,PM 任务集重新映射的 ERP 相关性显着改变。在 400 到 700 ms 之间前部分布的 TS LPC 振幅的增强导致了在这种组条件下增加的抑制伴随着增强的前部介导的神经激活的建议,这些神经激活支持优势正在进行的任务反应抑制处理。PM 任务集重新映射的 ERP 相关性通过诱导从回顾性记忆 (RM) 中检索到的不同 PM 响应产生规则而显着改变。在 400 到 700 ms 之间前部分布的 TS LPC 振幅的增强导致了在该组条件下增加的抑制伴随着增强的前部介导的神经激活的建议,这些神经激活支持优势进行中的任务反应抑制处理。PM 任务集重新映射的 ERP 相关性通过诱导从回顾性记忆 (RM) 中检索到的不同 PM 响应产生规则而显着改变。在 400 到 700 ms 之间前部分布的 TS LPC 振幅的增强导致了在该组条件下增加的抑制伴随着增强的前部介导的神经激活的建议,这些神经激活支持优势进行中的任务反应抑制处理。
