Inhibition of return to occluded objects.
Since many visual objects are vulnerable to occlusion, an active process that tracks objects behind occluders confers considerable ecological validity to the visual system. We studied this possibility by testing whether inhibition of return can be observed with occluded objects. In our experiments, two moving objects disappeared or reappeared behind occluders while a cue and a probe were presen...
متن کاملInhibition of return to an occluded object depends on expectation.
Inhibition of return (IOR) is indexed by slower reaction times to targets presented at previously attended locations or objects. If a moving object is occluded, some studies find IOR, others do not. Four experiments examined whether this inconsistency hinges on the observer's expectation as to whether the object continues to exist at the end of its motion sequence. Results showed that observer ...
متن کاملAttending to objects: Endogenous cues can produce inhibition of return
Inhibition of Return (IOR) is effective in a wide range of experimental settings but has proven elusive under conditions of volitional (endogenous) attentional control. This result may be due to a continuing attentional bias towards the cued location. Here we ask whether IOR can be unmasked under endogenous cueing conditions when a predictive cue prevents such a bias. In Experiment 1, a central...
متن کاملRecognition of Occluded Objects
3 Pattern recognition involves building a mental model to interpret incoming inputs. 4 This incoming information is often incomplete and the mental model must 5 extrapolate to complete the patterns, a process that is constrained by the statistical 6 regularities in nature. Examples of pattern completion involve identification of 7 objects presented under unfavorable luminance or interpretation ...
متن کاملPartly Occluded Objects
Newborn infants were familiarized to a three-dimensional display consisting of a rod which moved behind a central occluder, so that , only the top and bottom of the rod were visible. The infants’ eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infa...
