Sabine Kastner and crew show that when humans are cued to direct their attention to part of an object, uncued locations that are part of the same object are sampled periodically at about 8 Hz. Different, uncued, objects are also sampled at 4 Hz. This adds to a growing body of evidence that attention, and cognition in general, is rhythmic not continuous.
