Anne Treisman Visual Feature Binding Requires Reentry
Reentrant processing has been proposed as a critical mechanism in feature binding. To test this claim, participants were shown arrays of six pairs of crossed vertical and horizontal bars. In each pair, one bar was white; one was red, green, or blue. Identifying the orientation, but not the color, of the nonwhite bar in the target item required correct binding. Four dots appeared around one of t...
متن کاملVisual feature binding in early infancy.
How does the developing brain of the human infant solve the feature-binding problem when visual stimuli consisting of multiple colored objects are presented? A habituation--dishabituation procedure revealed that 1-month-old infants have the ability to discriminate changes in the conjunction of a familiar shape and color in two objects. However, this good earlier performance was followed by poor...
متن کاملVisual Segmentation and Feature Binding without Synchronization
There has recently been a sizable amount of work on visual segmentation in neural networks. Many of these networks have functioned by “tagging” the outputs of feature detectors as being features of one object or another. In particular, several models have appeared in which visual segmentation is performed by a network of oscillators; different objects are discriminated by setting the oscillator...
متن کاملVisual binding, reentry, and neuronal synchrony in a physically situated brain-based device
By constructing and analyzing a physically situated brain-based device (i.e. a device with sensors and actuators whose behavior is guided by a simulated nervous system), we show that reentrant connectivity and dynamic synchronization can provide an effective mechanism for binding the visual features of objects. The mammalian visual system contains a variety of cortical regions specialized to re...
متن کاملHierarchical, Localized Saliency Computations Solve the Visual Feature Binding Problem
Computational vision has a long history of proposing methods for decomposing a visual signal into components. What has been far more elusive is how to recombine those components into a whole, a problem known as the binding problem. Although several proposals have appeared, the approaches and their demonstrations seem weak at best. This paper proposes a novel solution for a significant portion o...
