Hemispheric performance in object-based attention

Hemispheric performance in object-based attention.

The goal of the present study was to investigate whether object-based attention effects differ across the cerebral hemispheres. Previous research has suggested that object-based attention is preferentially lateralized to the left hemisphere (Egly, Driver, & Rafal, 1994; Egly, Rafal, Driver, & Starrveveld, 1994). However, work by Vecera (1994) has suggested that these previous studies may have f...

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...

Hemispheric control of spatial attention.

According to the activation-orienting hypothesis the distribution of attention in space is biased in the direction contralateral to the more activated hemisphere. The present investigation tested this proposal and evaluated the nature of hemispheric differences in orienting control. Activation imbalance was produced by a unilateral visual stimulus. The distribution of attention was measured usi...
