在理解视觉工作记忆方面的最新进展,在这里扩展到研究听觉工作记忆的发展。视觉工作记忆是在正在进行的处理中使用的有限信息。对视觉对象数组的研究表明,如何从对象表示的精度来区分保留的对象数量的能力。在一项包括儿童(6-13岁,N=84)和成人(26-50岁,N=31)的调查中,我们将该技术应用于非音乐音调序列。对于每一个1到4个音调的系列,参与者通过使用80个选择的尺度来回应,试图在查询的序列位置重现音调。尽管与视觉对象相比,感觉记忆对音调的有用性要持久得多,但观察到的音调容量与之前对视觉容量的发现相似。研究结果还限制了儿童工作记忆发展的理论,表明音调表征的能力和精度随着年龄的增长而增加,这与视觉研究类似,而不是基于时间的记忆衰退的年龄差异。这些发现,包括容量、精度和一些辅助任务和问卷之间的相关模式,确立了容量和精度是可分离的过程,并对工作记忆发展的各种假设提出了重要的限制。
Recent advances in understanding visual working memory, the limited information held in mind for use in ongoing processing, are extended here to examine auditory working memory development. Research with arrays of visual objects has shown how to distinguish the capacity, in terms of the number of objects retained, from the precision of the object representations. We adapt the technique to sequences of non-musical tones, in an investigation including children (6–13 years, N=84) and adults (26–50 years, N=31). For each series of 1 to 4 tones, the participant responded by using an 80-choice scale to try to reproduce the tone at a queried serial position. Despite the much longer-lasting usefulness of sensory memory for tones compared to visual objects, the observed tone capacity was similar to previous findings for visual capacity. The results also constrain theories of childhood working memory development, indicating increases with age in both the capacity and the precision of the tone representations, similar to the visual studies, rather than age differences in time-based memory decay. The findings, including patterns of correlations between capacity, precision, and some auxiliary tasks and questionnaires, establish capacity and precision as dissociable processes and place important constraints on various hypotheses of working memory development.
