本研究采用简单检测任务、定位任务、目标扫视任务和控制辨别难度的目标识别任务4个实验，考察了视觉注意的反射性定向和自主性定向之间的关系。内源性和外源性的定向线索，在每一个试验和他们的有效性进行了正交操作，以检查是否注意机制是由不同的系统介导的，以及它们是否有添加剂和独立的视觉检测和歧视的影响。结果表明，除困难辨认任务外，每种定向机制在每种情况下都有其典型的、独立的效应。一个理论框架，了解内源性和外源性的注意定向之间的关系，提出，测试和确认。
The relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in each trial and their validity was manipulated orthogonally to examine whether attention mechanisms are mediated by separate systems and whether they have additive and independent effects on visual detection and discrimination. The results showed that each orienting mechanism developed its typical and independent effect in every case except for the difficult identification task. A theoretical framework for understanding the relationship between endogenous and exogenous orienting of attention is proposed, tested, and confirmed.
