This study explored how bottom-up scene features and top-down contextual knowledge integrate during visual perception and processing. EEG recordings were obtained from 30 participants while they performed scene memory and visuospatial tasks in an alternating manner. During this investigative procedure, the researchers manipulated the number of open doors as well as applied CNNs with Grad-CAM to decode neural dynamics. The researchers identified an early occipitoparietal integration window in which visual features and spatial memory can converge. To continue, it was found that newly acquired spatial knowledge altered neural responses. These findings demonstrate that spatial knowledge exerts a rapid top-down influence on scene perception.
