Prioritization in the coordination of multiple action modalities

这个项目的主要目的是更好地了解在协调涉及不同效应系统的行动时所涉及的优先次序机制。虽然许多关于动作控制的认知基础的研究通常将他们的分析局限于单一的效应系统（例如，手动按键反应的延迟/错误），但我们的日常行为通常涉及同时控制许多效应系统（例如，手，脚，眼睛，声道）。例如，撰写本提案需要同时执行手动按键和眼球运动。然而，到目前为止，关于如何在涉及多个动作同时协调的情况下确定特定效应系统的优先级的研究还很少。虽然对输入模式的优先排序（跨模态注意的研究）有大量的研究，但在处理的输出（动作）方面（跨模态动作控制）没有可比的传统。本提案旨在解决行动/行为控制领域这一令人惊讶和实质性的研究差距。在此背景下，本实验还旨在关注以前在多任务（密切相关）领域（例如，眼球运动，足部反应）中很大程度上被忽视的反应模式。研究结果将有助于进一步明确现有的多动作控制理论框架。

This project mainly aims at a better understanding of prioritization mechanisms involved in the coordination of actions involving different effector systems. While many studies of the cognitive underpinnings of action control usually restrict their analyses to only a single effector system (e.g., latency/errors of manual key press responses), our daily behavior typically involves the control of many effector systems (e.g., hand, foot, eye, vocal tract) simultaneously. For example, writing the present proposal involves the simultaneous execution of manual key presses and eye movements. However, up to now there is only sparse research on the issue of how we can prioritize specific effector systems in situations involving simultaneous co-ordination of multiple actions. While there is a substantial body of research on the prioritization of input modalities (research on cross-modal attention), there is no comparable tradition on the output (action) side of processing (cross-modal action control). The present proposal is intended to address this surprising and substantial research gap in the field of action/behavior control. In this context, the present experiments are also designed to focus on response modalities that have previously been largely neglected in the (closely related) field of multi-tasking (e.g., eye movements, foot responses). The results will help to further specify existing theoretical frameworks on multiple action control.
