Prospective memory (PM) involves remembering to perform an intended action in the future. Researchers have demonstrated that, under certain conditions, contextual information about when PM performance opportunities are likely to occur can support PM performance while decreasing the cognitive demands of the PM task. The current study builds upon prior work to investigate whether warning participants that a PM-relevant context was approaching would improve the efficiency of PM control processes and benefit PM accuracy. Participants completed an ongoing lexical decision task with an embedded PM task of responding to a target syllable. For context conditions, targets only appeared on trials where letter strings were colored red (PM-relevant context), while PM-irrelevant trials were green. The warning in Experiment 1 was embedded in the ongoing task (trials preceding PM-relevant contexts were colored yellow). In Experiment 2 the warning was separate from the ongoing task (1-s pre-trial red fixation preceding PM-relevant contexts). Context improved PM control efficiency and PM accuracy in both experiments. Context always improved PM accuracy for targets in the second and third trial positions of PM-relevant contexts; however, only the Experiment 2 warning generated an accuracy benefit for targets in the first trial position. Experiment 3 replicated the findings of Experiments 1 and 2 and also confirmed that color change without associated context was not responsible for the current results.

通过上下文提示改善预期记忆

预期记忆(PM)涉及记住将来执行预期的动作。研究人员证明,在某些条件下,有关何时可能出现PM绩效机会的上下文信息可以支持PM绩效,同时降低PM任务的认知需求。当前的研究以先前的工作为基础,以调查警告参与者是否正在接近与PM相关的环境会提高PM控制过程的效率并有益于PM准确性。参加者完成了正在进行的词汇决策任务,并嵌入了对目标音节做出响应的嵌入式PM任务。对于情境条件,仅在字母字符串显示为红色(与PM相关的情境)的试验中出现目标,而与PM不相关的试验为绿色。实验1中的警告已嵌入正在进行的任务中(与PM相关的上下文之前的试验用黄色表示)。在实验2中,警告与正在进行的任务是分开的(在与PM相关的上下文之前1-s进行审前红色注视)。在两个实验中,上下文均改善了PM控制效率和PM精度。在与PM相关的环境的第二和第三次试验位置中,情境始终可以提高目标的PM准确性;但是,只有“实验2”警告会为第一个试验位置中的目标产生准确性优势。实验3复制了实验1和2的发现,并确认没有相关上下文的颜色变化对当前结果不承担任何责任。在实验2中,警告与正在进行的任务是分开的(在与PM相关的上下文之前1-s进行审前红色注视)。在两个实验中,上下文均改善了PM控制效率和PM精度。在与PM相关的环境的第二和第三次试验位置中,情境始终可以提高目标的PM准确性;但是,只有“实验2”警告会为第一个试验位置中的目标产生准确性优势。实验3复制了实验1和2的发现,并确认没有相关上下文的颜色变化对当前结果不承担任何责任。在实验2中,警告与正在进行的任务是分开的(在与PM相关的上下文之前1-s进行审前红色注视)。在两个实验中,上下文均改善了PM控制效率和PM精度。在与PM相关的环境的第二和第三次试验位置中,情境始终可以提高目标的PM准确性;但是,只有“实验2”警告会为第一个试验位置中的目标产生准确性优势。实验3复制了实验1和2的发现,并确认没有相关上下文的颜色变化对当前结果不承担任何责任。只有“实验2”警告为第一个试验位置中的目标产生了准确性优势。实验3复制了实验1和2的发现,并确认没有相关上下文的颜色变化对当前结果不承担任何责任。只有“实验2”警告为第一个试验位置中的目标产生了准确性优势。实验3复制了实验1和2的发现,并确认没有相关上下文的颜色变化对当前结果不承担任何责任。
