Abstract

If the observer is not moving object movement is uniquely signalled by retinal image motion. Under such circumstances a moving object captures attention. During self-movement the global image motion that results from movement of the eyes may mask the image motion that signals object movement. We investigated whether a moving object captures attention in this case. Through stereo glasses, observers viewed 24 objects arranged in a 3-D volume. Four of the objects were potential target objects that could change shape. During viewing the camera viewpoint was translated and rotated to simulate self-movement. Observers were required to identify a shape change as rapidly as possible. On every 35th trial an object within the scene would unexpectedly move at approximately the same time as the shape change. When the object that changed shape was also the object that moved, response time was shorter that when a different object moved; this is the hallmark of attentional capture. Therefore we conclude that during self-movement, unexpected object movement captures attention.
