Measures of working memory capacity (WMC) are extremely popular, yet we know relatively little about the specific processes that support recall. We focused on children's and adults' ability to use contextual support to access working memory representations that might otherwise not be reported. Children ( N = 186, 5-10 years) and adults ( N = 64) completed a listening span task and a delayed recall task with semantic probes or cues. Clear age-related increases in listening span were evident. All age groups benefitted from contextual support to retrieve degraded target memoranda, particularly on listening span tasks when the cues provided semantic support for processing events, in comparison to cues associated specifically with memoranda. Response latencies suggested a developing efficiency in children's use of contextual support for delayed recall correlated with listening span performance. These probe tasks support accounts of working memory that recognise reconstructive and cued search processes.
工作记忆容量(WMC)的测量方法非常流行,但我们对支持回忆的具体过程了解相对较少。我们关注儿童和成人利用情境支持来获取可能无法报告的工作记忆表征的能力。儿童(N = 186,5 - 10岁)和成人(N = 64)完成了一个听力广度任务以及一个带有语义探测或线索的延迟回忆任务。听力广度明显呈现出与年龄相关的增长。与专门与记忆项目相关的线索相比,所有年龄组在利用情境支持来检索退化的目标记忆内容时都受益,特别是在听力广度任务中当线索为处理事件提供语义支持时。反应潜伏期表明儿童在延迟回忆中利用情境支持的效率不断提高,这与听力广度表现相关。这些探测任务支持了那些认识到重构和线索搜索过程的工作记忆理论。
