Document Summary
Can only attend to a little bit of all the sensory information you experience. Intensity of stimulus influences whether it captures your attention. Attention may be almost the same thing as working memory. We have an internal spatial map of the visual environment. Ew can move our attention around to focus on various parts of our visual field. You can narrow it, or expand it. Location based theories we attend to regions of the visual field. Spotlight can move in the absence of eye movements. Object-based theories we attend to objects, not regions of space. To achieve behavioural goals, action must be directed to only one object at a time. Attention, then may be the mechanism that selects particular objects (more precisely their internal representation) to guide action. Demonstrated that one of two superimposed objects that provide no obvious spatial bases for selection can be readily selected. Subjects were presented with two overlapping images of different colours.
