Contextual cueing of visual attention.
Visual context information constrains what to expect and where to look, facilitating search for and recognition of objects embedded in complex displays. This article reviews a new paradigm called contextual cueing, which presents well-defined, novel visual contexts and aims to understand how contextual information is learned and how it guides the deployment of visual attention. In addition, the...
متن کاملAttention and non-retinotopic feature integration.
Features of moving objects are non-retinotopically integrated along their motion trajectories as demonstrated by a variety of recent studies. The mechanisms of non-retinotopic feature integration are largely unknown. Here, we investigated the role of attention in non-retinotopic feature integration by using the sequential metacontrast paradigm. A central line was offset either to the left or ri...
متن کاملRetinotopic effects during spatial audio-visual integration.
The successful integration of visual and auditory stimuli requires information about whether visual and auditory signals originate from corresponding places in the external world. Here we report crossmodal effects of spatially congruent and incongruent audio-visual (AV) stimulation. Visual and auditory stimuli were presented from one of four horizontal locations in external space. Seven healthy...
متن کاملRetinotopic organization of early visual spatial attention effects as revealed by PET and ERPs.
Cerebral blood flow PET scans and high-density event-related potentials (ERPs) were recorded (separate sessions) while subjects viewed rapidly-presented, lower-visual-field, bilateral stimuli. Active attention to a designated side of the stimuli (relative to passive-viewing conditions) resulted in an enhanced ERP positivity (P1 effect) from 80-150 msec over occipital scalp areas contralateral t...
متن کاملContextual cueing: implicit learning and memory of visual context guides spatial attention.
Global context plays an important, but poorly understood, role in visual tasks. This study demonstrates that a robust memory for visual context exists to guide spatial attention. Global context was operationalized as the spatial layout of objects in visual search displays. Half of the configurations were repeated across blocks throughout the entire session, and targets appeared within consisten...
