A question of perspective: Perspective as a feature in stimulus-response binding.

In action control research, stimulus-response binding and retrieval processes are assumed core mechanisms. Stimulus and response features are integrated into event files when they occur together. This event file is retrieved if any feature is repeated. Partial mismatches between current and retrieved episodes cause conflicts, leading to performance costs, while full matches improve performance (the difference between these conditions is known as binding effects). Such binding effects have been found for different stimulus features like colour, shape, or location, using stimulus material that is often kept very simple. In our study, we manipulated the perspective on a real-world three-dimensional distractor stimulus. We found that perspective was bound to the response, independent of stimulus identity. It seems that perspective is treated as a stimulus feature in action control. This result enhances the way we discuss what a feature actually is and how features are bound in event files.
