Modeling the Dynamics of Feature Binding During Object-Selective Attention
Objects in the environment may be attended selectively and perceived as unified ensembles of their constituent features. To investigate the timing and cortical localization of feature-integration mechanisms in object-based attention, recordings of event-related potentials and magnetic fields were combined with functional MRI while subjects attended to one of two superimposed transparent surface...

متن کاملSelective Tuning: Feature Binding Through Selective Attention
We present a biologically plausible computational model for solving the visual binding problem. The binding problem appears due to the distributed nature of visual processing in the primate brain, and the gradual loss of spatial information along the processing hierarchy. The model relies on the reentrant connections so ubiquitous in the primate brain to recover spatial information, and thus al...
متن کاملFeature binding, attention and object perception.
The seemingly effortless ability to perceive meaningful objects in an integrated scene actually depends on complex visual processes. The 'binding problem' concerns the way in which we select and integrate the separate features of objects in the correct combinations. Experiments suggest that attention plays a central role in solving this problem. Some neurological patients show a dramatic breakd...
متن کاملEarly Visual Cortex Dynamics during Top-Down Modulated Shifts of Feature-Selective Attention
Shifting attention from one color to another color or from color to another feature dimension such as shape or orientation is imperative when searching for a certain object in a cluttered scene. Most attention models that emphasize feature-based selection implicitly assume that all shifts in feature-selective attention underlie identical temporal dynamics. Here, we recorded time courses of beha...
