Object-based saccadic selection during scene perception: evidence from viewing position effects.
The goal of the present study was to further test the hypothesis that objects are important units of saccade targeting and, by inference, attentional selection in real-world scene perception. To this end, we investigated where people fixate within objects embedded in natural scenes. Previously, we reported a preferred viewing location (PVL) close to the center of objects (Nuthmann & Henderson, ...
متن کاملSpatial statistics and attentional dynamics in scene viewing.
In humans and in foveated animals visual acuity is highly concentrated at the center of gaze, so that choosing where to look next is an important example of online, rapid decision-making. Computational neuroscientists have developed biologically-inspired models of visual attention, termed saliency maps, which successfully predict where people fixate on average. Using point process theory for sp...
متن کاملStrategic effects on object-based attentional selection.
The same-object benefit, that is faster and/or more accurate performance when two target properties to be identified appear on one object than when each of the properties appear on different objects, has been a robust and theoretically important finding in the study of attentional selection. Indeed, the same-object benefit has been interpreted to suggest that attention can be used to select obj...
متن کامل[Role of connectedness in early object-based attentional selection].
It has been suggested that uniform connectedness is the most fundamental factor in forming units of attentional selection, while there are evidences that attention can select a perceptual group that consists of separate elements with similar features. The present study examined the effects of connectedness and a boundary-feature similarity on early spatial-selection processes using a sustained-...
متن کاملNeural correlates of object-based attentional selection in human cortex.
Humans can attend to different objects independent of their spatial locations. While selecting an object has been shown to modulate object processing in high-level visual areas in occipitotemporal cortex, where/how behavioral importance (i.e., priority) for objects is represented is unknown. Here we examined the patterns of distributed neural activity during an object-based selection task. We m...
