渐近优先性及其机制
Looming Priority and Its Mechanism

查看参考文献74篇

文摘 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.
其他语种文摘 The looming priority refers to organisms'prior processing of or greater sensitivity to looming signals. The looming priority has been commonly found in visual,auditory and cross modalities and different kinds of subjects including human and animals. Humanneuroimaging studies suggest that neural substrate associated with the priority involves a massive distributed neural network coordinating and communicating to each other,including the superior temporal sulcus,right temporoparietal junction and some motor areas. The neurons and neural pathways selectively sensitive to looming signals have been found in many kinds of animals. The looming priority is explained from different perspectives,including threatening hypothesis,attentional capture hypothesis and automatic processing hypothesis. Future studies may focus on the role of social and emotional features of looming stimuli and the integration mechanism of multisensory looming stimuli.
