Feature-location binding, the "spatial congruency bias", and object-based attention

Object-location binding across a saccade: A retinotopic spatial congruency bias.

Despite frequent eye movements that rapidly shift the locations of objects on our retinas, our visual system creates a stable perception of the world. To do this, it must convert eye-centered (retinotopic) input to world-centered (spatiotopic) percepts. Moreover, for successful behavior we must also incorporate information about object features/identities during this updating - a fundamental ch...

Binding object features to locations: Does the "spatial congruency bias" update with object movement?

One of the fundamental challenges of visual cognition is how our visual systems combine information about an object's features with its spatial location. A recent phenomenon related to object-location binding, the "spatial congruency bias," revealed that two objects are more likely to be perceived as having the same identity or features if they appear in the same spatial location, versus if the...

The influence of object location on identity: a "spatial congruency bias".

Objects can be characterized by a number of properties (e.g., shape, color, size, and location). How do our visual systems combine this information, and what allows us to recognize when 2 objects are the same? Previous work has pointed to a special role for location in the binding process, suggesting that location may be automatically encoded even when irrelevant to the task. Here we show that ...

Journal of Experimental Psychology: General The Influence of Object Location on Identity: A “Spatial Congruency Bias”

Feature 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...
