摘要
注意力是对日常生活至关重要的核心认知领域。在老年听力损失患者中使用注意力网络测试（ANT）和事件相关电位（ERPs），可以很好地了解听力损失对注意力过程的影响。因此，本研究旨在了解有听力损失和无听力损失的老年人的注意力缺陷及其皮层动态变化。本研究共招募了 40 名参与者，其中 20 名是听力损失的老年人，20 名是与年龄和教育程度相匹配的听力正常的对照组。所有参与者都接受了使用 ANT 进行的认知评估，并同时进行了 32 通道脑电图记录。结果显示，与听力正常的老年人相比，听力损失老年人的执行注意力明显受损，警觉和定向注意力也发生了细微变化。这些研究结果表明，听力损失对注意力网络有负面影响。此外，ANT和ERPs还有助于深入了解与听力损失相关的特定注意网络缺陷的潜在神经机制。
Investigating the impact of hearing loss on attentional networks among older individuals: an event-related potential study
Attention is a core cognitive domain crucial in facilitating day-to-day life. Using an attention network test (ANT) along with event-related potentials (ERPs) in older individuals with hearing loss would provide excellent information about the impact of hearing loss on attentional processes. Thus, the current study aims to understand the attentional deficits and its cortical dynamics in older individuals with and without hearing loss. The study recruited 40 participants, 20 older individuals with hearing loss and 20 age and education-matched controls with normal hearing. All the participants underwent cognitive assessment using ANT with simultaneous 32-channel EEG recording. Results revealed significant impairment in executive attention and subtle alterations in alerting and orienting attention among older individuals with hearing loss compared to their normal-hearing counterparts. These findings suggest the negative impact of hearing loss on attentional networks. In addition, ANT and ERPs provide insight into the underlying neural mechanisms in specific attention network deficits associated with hearing loss.
期刊介绍：
Cognitive Neurodynamics provides a unique forum of communication and cooperation for scientists and engineers working in the field of cognitive neurodynamics, intelligent science and applications, bridging the gap between theory and application, without any preference for pure theoretical, experimental or computational models.
The emphasis is to publish original models of cognitive neurodynamics, novel computational theories and experimental results. In particular, intelligent science inspired by cognitive neuroscience and neurodynamics is also very welcome.
The scope of Cognitive Neurodynamics covers cognitive neuroscience, neural computation based on dynamics, computer science, intelligent science as well as their interdisciplinary applications in the natural and engineering sciences. Papers that are appropriate for non-specialist readers are encouraged.
1. There is no page limit for manuscripts submitted to Cognitive Neurodynamics. Research papers should clearly represent an important advance of especially broad interest to researchers and technologists in neuroscience, biophysics, BCI, neural computer and intelligent robotics.
2. Cognitive Neurodynamics also welcomes brief communications: short papers reporting results that are of genuinely broad interest but that for one reason and another do not make a sufficiently complete story to justify a full article publication. Brief Communications should consist of approximately four manuscript pages.
3. Cognitive Neurodynamics publishes review articles in which a specific field is reviewed through an exhaustive literature survey. There are no restrictions on the number of pages. Review articles are usually invited, but submitted reviews will also be considered.
