<i>you are required to split your attention between multiple sources of information </i>(2018) for string quartet and large ensemble presents the players with a stream of auditory cues to which they must respond with specified sounds. The cues regularly switch between different types and are directed at different sub-groups within the two ensembles, requiring the players to think and act very quickly. The piece explores cognitive load and the way we remember associations between cues and responses. The cues include samples of real-world sounds which induce a range of different responses, as well as text-to-speech computer voices reading extracts from the Harvard Sentences (a set of phonetically balanced texts developed in the 1960s to test artificial voice modelling) and giving other verbal cues. The title is adapted from Mousavi, Low and Sweller’s 'Reducing Cognitive Load by Mixing Auditory and Visual Presentation Modes’ (1995) in which they investigate the split-attention effect and its impact on cognitive load. In the piece, all the cues and responses are aural, requiring players to negotiate the stream of information in one mode. The increased cognitive load affects the speed of response by players and the variations in time required to complete sound-producing actions on the different instruments, producing an unpredictable trail of sounds after each cue.<br>This item contains the research timeline and research questions for <i>you are required to split your attention between multiple sources of information</i>.

《需在多信息源间分配注意力》（You Are Required to Split Your Attention Between Multiple Sources of Information）是2018年为弦乐四重奏（string quartet）与大型乐团（large ensemble）创作的作品，该作品会向演奏者推送一系列听觉提示，要求其以指定声响做出回应。这些提示会在不同类型间不断切换，并针对两个乐团中的不同子群体发出，这要求演奏者快速思考并即时行动。该作品旨在探究认知负荷（cognitive load）以及我们如何记住提示与回应间的关联。提示内容包括可引发多种不同回应的现实世界声音采样，以及朗读《哈佛语句》（Harvard Sentences）节选的文本转语音（text-to-speech）电脑语音——《哈佛语句》是1960年代为测试人工语音建模（artificial voice modelling）而开发的语音平衡文本集——同时还会提供其他语言提示。该作品标题改编自Mousavi、Low与Sweller于1995年发表的《通过混合听觉与视觉呈现模式降低认知负荷》（Reducing Cognitive Load by Mixing Auditory and Visual Presentation Modes），该研究探讨了注意力分散效应（split-attention effect）及其对认知负荷的影响。在这部作品中，所有提示与回应均为听觉形式，要求演奏者仅通过单一模态处理信息流。持续提升的认知负荷会影响演奏者的响应速度，且不同乐器完成发声动作所需的时长存在差异，这会在每条提示之后产生一段不可预测的声响序列。
