Research on saccadic and pursuit eye movements led to great advances in our understanding of sensorimotor processing and human behavior. However, studies often have focused on isolated saccadic and pursuit eye movements measured with respect to different sensory information (static vs. dynamic targets). Here, we leveraged interindividual differences across a carefully balanced combination of different tasks to demonstrate that critical links in the control of oculomotor behavior were previously missed. We observed correlations in eye movement behavior across tasks, but only when compared with the same sensory information (e.g., pursuit gain and accuracy of saccades to moving targets). Within the same task, the coordination of saccadic and pursuit eye movements was tailored to the strengths of the individual: observers with more accurate saccades to moving targets rely on them more to catch up with moving targets. Our results have profound implications for the theoretical understanding of sensorimotor processing for oculomotor control. They necessitate a reevaluation of previous data used to map brain circuits for saccadic and pursuit eye movements measured with different types of relevant sensory information. Additionally, they underscore the importance of moving beyond average observations to embrace individual differences as a rich source of information. These individual differences not only reveal the strengths and weaknesses of observers. When combined across different tasks, they allow insights about why observers behave differently in a given task. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

个体差异将感觉处理和运动控制联系起来。


对扫视和追踪眼球运动的研究使我们对感觉运动处理和人类行为的理解取得了巨大进步。然而，研究通常集中于根据不同的感官信息（静态与动态目标）测量的孤立的扫视和追踪眼球运动。在这里，我们利用不同任务的仔细平衡组合中的个体差异来证明以前错过了控制动眼行为的关键环节。我们观察到跨任务眼动行为的相关性，但仅限于与相同的感官信息（例如，追踪增益和对移动目标的扫视准确性）进行比较。在同一任务中，扫视和追踪眼球运动的协调是根据个人的优势量身定制的：对移动目标进行扫视更准确的观察者更依赖它们来追赶移动目标。我们的结果对于动眼神经控制的感觉运动处理的理论理解具有深远的影响。他们需要重新评估以前的数据，这些数据用于绘制用不同类型的相关感官信息测量的扫视和追踪眼球运动的大脑回路。此外，他们还强调了超越平均观察结果、接受个体差异作为丰富信息来源的重要性。这些个体差异不仅揭示了观察者的优点和缺点。当跨不同任务组合时，它们可以洞察观察者在给定任务中表现不同的原因。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
