Attentional Selection
Top-Down, Bottom-Up and History-Based Biases
In this Element
A framework is proposed in which it is assumed that visual selection is the result of the interaction between top-down, bottom-up and selection-history factors.
The Element discusses top-down attentional engagement and suppression, bottom-up selection by abrupt onsets and static singletons as well as lingering biases due to selection-history entailing priming, reward and statistical learning.
We present an integrated framework in which biased competition among these three factors drives attention in a winner-take-all-fashion.
We speculate which brain areas are likely to be involved and how signals representing these three factors feed into the priority map which ultimately determines selection.
