The concept of attention refers to a set of related processes that have important
consequences for cognitive functioning. Perhaps the most widely recognized of these …

How does the brain work? After a century of research, we still lack a coherent view of how
neurons process signals and control our activities. But as the field of computational …

We describe a formal framework for analyzing how statistical properties of natural
environments and the process of natural selection interact to determine the design of …

Attention can modulate sensitivity to local stimuli in early vision [1–6]. But, can attention also
modulate integration of local stimuli into global visual patterns? We recently measured …

In a task in which the observer must detect a signal at two locations, presenting a precue that
predicts the location of a signal leads to improved performance with a valid cue (signal …

Multiple attributes of a visual array are often more efficiently processed when they are
attributes of a single object than when they are attributes of different objects—a pattern …

An influential assumption for the front end of models in vision, visual search, and object
recognition is an analysis of independent features that correspond to basic image …

Spatial cueing in an orientation discrimination task with targets embedded in high or low
external noise indicates noise exclusion as a primary mechanism for attentional modulation …
