Surface-Object Interactions in Object-Based Attention

Attention-based Object Detection

Interference between object-based attention and object-based memory.

Research has shown that there are at least two kinds of visual selective attention: location based and object based. In the present study, we sought to determine the locus of spatially invariant object-based selection using a dual-task paradigm. In four experiments, observers performed an attention task (object feature report or visual search) with a concurrent memory task (object memory or spa...

Learning Object-based Attention Control

Remarkable efficiency of human vision is the main reason of being the most-studied mode of perception in machine learning. Despite the huge active research in computer vision and robotics, many real-world visumotor tasks that are easily performed by humans are still unsolved. Of special interest is designing efficient learning algorithms, in terms of high accuracy and low computational cost, fo...

Object-based attention without awareness.

Attention and awareness are often considered to be related. Some forms of attention can, however, facilitate the processing of stimuli that remain unseen. It is unclear whether this dissociation extends beyond selection on the basis of primitive properties, such as spatial location, to situations in which there are more complex bases for attentional selection. The experiment described here show...

Object-based attention: strength of object representation and attentional guidance.

Two or more features belonging to a single object are identified more quickly and more accurately than are features belonging to different objects--a finding attributed to sensory enhancement of all features belonging to an attended or selected object. However, several recent studies have suggested that this "single-object advantage" may be a product of probabilistic and configural strategic pr...
