Cue Validity and Object-Based Attention

Cue validity and object-based attention.

In a previous study, Egly, Driver, and Rafal (1994) observed both space- and object-based components of visual selective attention. However, the mechanisms underlying these two components and the relationship between them are not well understood. In the present research, with a similar paradigm, these issues were addressed by manipulating cue validity. Behavioral results indicated the presence ...

Central-cue discriminability modulates object-based attention by influencing spatial attention.

The role of central-cue discriminability in modulating object-based effects was examined using Egly, Driver, and Rafal's (1994) "double-rectangle" spatial cueing paradigm. Based on the attentional focusing hypothesis (Goldsmith & Yeari, 2003), we hypothesized that highly discriminable central-arrow cues would be processed with attention spread across the two rectangles (potential target locatio...

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...
