Abstract

When we view a scene, we generally feel that we have a rich representation of that scene. Recent research has shown, however, that we are unable to detect relatively large changes in scenes, which suggests an inability to retain the visual details from one scene view to the next. In the present study, we investigated whether we can retain and make use of global and semantic information from a scene in order to efficiently detect changes from one scene to the next. Results indicated that change detection was practically independent of scene disruption with one exception. Better performance in the meaningful scenes was observed only in the whole-scene presentation condition where the participants knew that the stimulus was extracted from the meaningful scene. Keywords: scene recognition, visual memory, change blindness

Abstract

This study examined infants' visual perception of three-dimensional common objects. It has been reported that human adults perceive object images in a view-dependent manner: three-quarter views are often preferred to other views, and the sensitivity to object orientation is lower for three-quarter views than for other views. We tested whether such characteristics were observed in 6- to 8-month-old infants by measuring their preferential looking behavior. In Experiment 1 we examined 190- to 240-day-olds' sensitivity to orientation change and in Experiment 2 we examined these infants' preferential looking for the three-quarter view. The 240-day-old infants showed a pattern of results similar to adults for some objects, while the 190-day-old infants did not. The 240-day-old infants' perception of object view is (partly) similar to that of adults. These results suggest that human visual perception of three-dimensional objects develops at 6 to 8 months of age.
