作者调查了在现实世界的场景观看过程中，相对于新对象的外观，对象颜色的变化明显优先于固定的程度。这两种类型的场景变化在注视期间引入时都会吸引目光（和注意力），尽管颜色变化比新物体更不容易吸引注意力。当这些场景变化发生在扫视过程中时，它们都没有引起注意，但是较慢且不太可靠的基于记忆的机制仍然能够优先考虑新对象和相对于场景中其他稳定对象的颜色变化。这些结果表明，在线记忆的对象身份和至少一些对象的功能，在检测到现实世界的场景变化。此外，视觉因素，如发病和颜色变化的显着性不影响这些事件的优先级。我们讨论了这些结果在当前的理论内的注意力分配，和在线记忆表征，现实世界的场景。
The authors investigated the extent to which a change to an object's colour is overtly prioritized for fixation relative to the appearance of a new object during real-world scene viewing. Both types of scene change captured gaze (and attention) when introduced during a fixation, although colour changes captured attention less often than new objects. Neither of these scene changes captured attention when they occurred during a saccade, but slower and less reliable memory-based mechanisms were nevertheless able to prioritize new objects and colour changes relative to the other stable objects in the scene. These results indicate that online memory for object identity and at least some object features are functional in detecting changes to real-world scenes. Additionally, visual factors such as the salience of onsets and colour changes did not affect prioritization of these events. We discuss these results in terms of current theories of attention allocation within, and online memory representations of, real-world scenes.
