In this week's Journal of Neuroscience, Cavanaugh and Wurtz dissect a curious phenomenon, "change blindness." We all, perhaps unknowingly, experience this effect hundreds of times each day. For example, when a new feature appears in our visual field, our attention shifts. During the eye movements (saccades) that redirect central vision, we are blind to changes in the visual scene. The authors hypothesized that a oordinated mechanism is responsible for saccadic movement and attentional shifts.
