One of the central questions of high-level human vision concerns the functional roles of bottom-up/feed-forward and top-down/feedback connections. In the first funding period, we found that the evidence for purely feed-forward processing in human object recognition is much weaker than currently thought. In the second funding period, we will investigate the question of feed-forward vs. feedback processing across a variety of different tasks, thereby investigating how the human visual system adapts to the different task-demands and whether other tasks than the priming paradigm admit top-down influences more directly.
