"Working off the summer lethargy with an empirical exercise"

According to some (in)famous theories, attention is necessary to consciously perceive objects in the visual field. The crux is that we cannot attend to all items simultaneously, but have to shift attention serially towards different locations in the visual field. Given these limitations, it is important to find out what guides visual attention and which objects are selected first for further processing. Current theories of attentional guidance claim that attention is guided by two attentional systems; first, a purely stimulus-driven selection mechanism that directs attention towards salient items (i.e., items with high feature contrast), and secondly, a goal-directed mechanism that guides attention towards specific feature values that match the observers' intentions (e.g., red items). In my talk, I will review some of the critical evidence and propose a different explanation for some of the findings. In
