中文摘要: 基于刺激属性的自上而下的注意控制是人类选择相关信息并抑制无关信息的关键,正成为注意研究的焦点。本项目计划采用各种经典实验范式,包括视觉搜索、注意瞬脱、空间注意盲和双任务干扰范式,并综合采用眼动和脑电等指标来解答以下几方面的关键问题:(1)自上而下的视觉注意控制系统可以表征哪些刺激属性?(2)自上而下的注意控制机制如何表征多个刺激属性?(3)关联性注意捕捉与刺激驱动型注意捕捉是如何交互的?(4)关联性注意捕捉的自动化程度;(5)自上而下的注意控制机制转换的时间进程。这一项目的研究不仅能系统揭示注意控制机制的外显行为特征和神经电生理指标,为检验和发展新的注意理论提供实验依据,而且还具有重要的应用价值,可以为监测评估人机界面中的各种干扰源提供理论指导和测量工具。

英文摘要: Top-down control of feature-based attention recently became the focus of attentional research. The present study propose to examine how top-down control of feature-based attention selects relevant information and suppress irrelevant information with presence of significant distraction. Multiple paradigms including visual search, attentional blink, spatial blink and dual-tasks paradigm will be used to answer the following questions: (1) What kind of visual features can involuntarily capture attention? (2)How can attention be guided by multiple target defining features? (3) How does contingent capture interact with stimulus-driven capture of attention? (4) Is contingent capture truly automatic? (5) How long it takes to switch from one attentional control setting to another? This study will not only improve our understanding of top-down control of attention but also help us identify important source of distraction, thus promoting efficient human-computer interaction.
