对渐近信号的优先加工被称为渐近优先性,该效应普遍存在于人类和动物的视觉、听觉和跨感觉通道中.人类神经影像学研究发现负责加工渐近信号的脑区涉及一个大规模相互协作和沟通的分布式神经网络,包括颞上沟、颞顶叶连接处以及一些运动区.对多种动物的细胞水平研究也发现了对渐近信号选择性敏感的神经元和神经通路.威胁论、注意捕获理论和自动加工理论从不同角度解释了渐近优先性产生的原因.未来研究可进一步考察刺激的社会、情绪等属性对渐近优先性的影响,探索多通道渐近渐远信息的整合和注意分配机制.
The preferential processing of asymptotic signals is called asymptotic priority, which is prevalent in the visual, auditory, and trans-sensory pathways of humans and animals.Human neuroimaging studies have found that the brain area responsible for the processing of asymptotic signals involves a large Scale distributed neural networks that collaborate and communicate with each other, including the superior temporal sulcus, temporo-parietal junction, and some motor regions.A variety of animal cell-level studies have also found neurons and neural pathways that are selectively sensitive to asymptotic signals Threat theory, attention capture theory and automatic processing theory explain the causes of asymptotic priority from different angles.Future research may further investigate the influence of stimulating social and emotional attributes on asymptotic priority, and explore the multi-channel asymptotic approach Far from the integration of information and attention allocation mechanism.
