Allocation of attention to a complex scene is an essential part of everyday life, from recreation such as playing a team sport (attending to different players, the ball, and distracters in the crowd) to workplaces such as monitoring the cockpit of a modern aeroplane (listening to radio communications, monitoring dials, and tactile feedback). Psychologists have typically studies attention in the laboratory by studying attention in a single modality (typically vision). However, as the pilot example above demonstrates, attention often needs to be deployed across modalities, and with different priorities (for example the altitude warning alarm should receive more attention than the cabin temperature gauge). Therefore, this project will explore the allocation of attention across modalities.We have recently shown (Crowe et al., 2019) that attention can be split in an unequal manner across different moving objects within a modality (vision). This project will further explore the nature of unequal attention allocation and will aim to examine how attention can be applied unequally across different modalities simultaneously. Psychophysical approaches, alongside eye tracking and behavioural (both in lab and online) will be used to test the limits of the attentional system to spit attention. Novel experiments will allow us to ask questions about the nature and architecture of the attention system which has traditionally only be studied within a modality. However, in the real-world people need to pay attention to multiple sources from different modalities (a doctor might need to listen to a heart rate monitor sound while also viewing the display of an EKG monitor)- how people manage this attention splitting is largely underexplored. By combining different stimulus modalities within a task, we can scale our basic science findings up to more realistic situations, while still maintaining tight control of the experimental setting. A further aspect of this project will look at he dynamic nature of the stimuli: whether they are static and unchanging, or moving and changing. This is important to understand how responsive the attention allocation process can be to online changes in the environment.This is in collaboration with Macquarie University and Dr Anina Rich.This project falls within the EPSRC Engineering research area. The project will provide results that can be translated into design choices for applications including augmented reality, wearable technology, and assistive technologies. Crowe, E. M., Howard, C.

将注意力分配到复杂的场景是日常生活的重要组成部分，从诸如团队运动等娱乐活动（注意不同的球员、球和人群中的干扰物）到诸如监控现代飞机驾驶舱（收听无线电通信、监控刻度盘和触觉反馈）等工作场所。心理学家通常在实验室中通过研究单一模式（通常是视觉）的注意力来研究注意力。然而，正如上面的试点示例所示，通常需要跨模式并具有不同的优先级来部署注意力（例如，高度警告警报应该比机舱温度计受到更多关注）。因此，该项目将探索跨模态的注意力分配。我们最近表明（Crowe et al., 2019），注意力可以以不平等的方式在模态（视觉）内的不同移动对象之间分配。该项目将进一步探讨不平等注意力分配的本质，并旨在研究如何同时在不同模式中不平等地应用注意力。心理物理学方法以及眼球追踪和行为（实验室和在线）将被用来测试注意力系统的注意力限制。新颖的实验将使我们能够提出有关注意力系统的性质和架构的问题，而传统上，注意力系统只能在某种模式下进行研究。然而，在现实世界中，人们需要关注来自不同方式的多个来源（医生可能需要一边听心率监测器的声音，一边观看心电图监测器的显示）——人们如何管理这种注意力分散在很大程度上尚未得到充分探索。通过在任务中结合不同的刺激方式，我们可以将我们的基础科学发现扩展到更现实的情况，同时仍然保持对实验环境的严格控制。该项目的另一个方面将着眼于刺激的动态性质：它们是静态的、不变的，还是移动的、变化的。这对于了解注意力分配过程对环境在线变化的反应程度非常重要。这是与麦格理大学和 Anina Rich 博士合作的。该项目属于 EPSRC 工程研究领域。该项目将提供可转化为增强现实、可穿戴技术和辅助技术等应用的设计选择的结果。 Crowe, E.
