The role of scene context in object recognition: Timing and mechanisms.

One remarkable aspect of human perception is the ability to extract the meaning of a target within a complex scene quickly. Consistent scenes between targets and backgrounds enhance visual understanding, yet the precise timing and underlying mechanisms of this effect remain unclear. To address this, two experiments were conducted exploring how object category, scene orientation, and scene consistency influence object recognition under conscious (Experiment 1) and unconscious (Experiment 2) conditions. Both experiments revealed an animate advantage, facilitation by scene consistency, and orientation-specific enhancements in object recognition. Performance was improved when both the object and the scene were upright, and furniture targets were more affected by scene consistency than animal targets. Specifically, under the conscious condition, the animate advantage was observed only for inconsistent scenes, whereas under the unconscious condition, the animate advantage was not influenced by scene consistency. Interestingly, in the unconscious state, the effects of target category and background orientation depended on scene consistency, with animals consistent with the background and furniture inconsistent with the background both influenced by orientation. These results suggest that scene context influences object recognition in the early stage of visual processing, and furniture recognition is more sensitive to contextual regularities than animal recognition.
