在R.这种差异表明定向模式（内源性与外源性）和选择模式（基于对象的基于空间）之间的相互依存关系。但是，定向模式通常与初始注意力的重点相混淆：内源性定向始于关注中心提示，而外源性定向则始于注意力广泛扩散。在这项研究中，通过实验表明，对于内源性和外源提示，基于对象的效应都在鼓励传播注意力的条件下获得基于对象的效应的实验检查和支持，但在鼓励集中注意力的条件下会减弱它们。讨论了对基于对象的注意的一般影响。
In R. Egly, J. Driver, and R. D. Rafal's (1994) influential double-rectangle spatial-cuing paradigm, exogenous cues consistently induce object-based attention, whereas endogenous cues generally induce space-based attention. This difference suggests an interdependency between mode of orienting (endogenous vs. exogenous) and mode of selection (object based vs. space based). However, mode of orienting is generally confounded with initial focus of attention: Endogenous orienting begins with attention focused on a central cue, whereas exogenous orienting begins with attention widely spread. In this study, an attentional-focusing hypothesis is examined and supported by experiments showing that for both endogenous and exogenous cuing, object-based effects are obtained under conditions that encourage spread attention, but they are attenuated under conditions that encourage focused attention. General implications for object-based attention are discussed.
