The time-course of feature-based attention effects dissociated from temporal expectation and target-related processes

Experiment Details

Human electroencephalography recordings from 20 participants. Participants viewed rapid sequences of overlaid oriented grating pairs while detecting a “target” grating of a particular orientation. We manipulated attention, one grating was attended and the other ignored (cued by colour), and temporal expectation, with stimulus onset timing either predictable or not.

Experiment length: 1 hour
