Eine Studie untersuchte, wie das Gehirn visuelle Informationen interpretiert und zeigt, dass die Aufmerksamkeit mit einer breiten Kategorie beginnt und sich dann auf das spezifische Merkmal von Interesse verengt, was bedeutet, dass die Aufmerksamkeitsmechanismen des Gehirns in einer Hierarchie organisiert sind

>How we focus our attention before we even see an object matters. For example, when we look for something moving in the sky, our expectation would be very different if the object is a bird flying past or a baseball coming straight at us.
>
>But it’s unclear whether our brain’s attention focuses first on a broad characteristic of the anticipated object, such as movement, or a specific feature — such as the direction of movement up or down.

>Researchers from the Center for Mind and Brain at the University of California, Davis, addressed this by analyzing electrical brain activity with machine-learning methods while human volunteers prepared to see colored dots moving on a screen. The study found that the brain’s attention focus starts with a broad category, then narrows down to the specific feature of interest. The study was published Aug. 19 in The Journal of Neuroscience.

>“Our study tells us that our brains first prepare to focus attention by activating neurons representing the broad category of the anticipated object and then quickly sharpens that focus,” said George R. Mangun
