We compared the effects of focussed attention upon event-related brain potentials (ERPs) to peripherally and centrally located visual stimuli in congenitally deaf subjects (Ss). The results were compared with those obtained from a group of normal hearing Ss in the same paradigm. ERPs from deaf and hearing Ss displayed similar attention-related changes with attention to the centrally located stimuli. These included enhanced amplitudes of the N1 component (157 ms) over the occipital regions of… Expand
Attention to central and peripheral visual space in a movement detection task. III. Separate effects of auditory deprivation and acquisition of a visual language
The results suggest that auditory deprivation and the acquisition of a visual language have marked and different effects on the development of cortical specializations in humans. Expand
Auditory and somatosensory event-related brain potentials in early blind humans
The present data suggest several compensatory changes in both auditory and somatosensory modalities after the onset of early visual deprivation, which appears to indicate enhanced automatic processing of auditory stimulus changes in the blind. Expand
Hemispheric Asymmetries in Deaf and Hearing During Sustained Peripheral Selective Attention.
Both deaf and hearing participants' selective attention was examined using electroencephalography and a frequency tagging paradigm, and both participant groups showed similar amplifications and reductions in the EEG signal at the attended and unattended frequencies, indicating similar control over their peripheral attention for motion stimuli.

The present event-related potential (ERP) study investigated whether attending to a particular direction of motion similarly enhances the processing of auditory and visual stimuli and results are discussed with regard to hierarchical models of attention. Expand
Visual evoked potentials and event related potentials in congenitally deaf subjects.
Significant reduced amplitudes were found in the occipital area for responses to motion and cognitive stimuli which might be interpreted as a part of functional reorganization of the extrastriate and cognitive cortical areas of deaf subjects. Expand
Visual Attention to the Periphery Is Enhanced in Congenitally Deaf Individuals
Enhanced peripheral attention to moving stimuli in the deaf may be mediated by alterations of the connectivity between MT/MST and the parietal cortex, one of the primary centers for spatial representation and attention. Expand
Changes in Early Cortical Visual Processing Predict Enhanced Reactivity in Deaf Individuals
It is found that deaf subjects were faster than hearing controls at detecting the visual targets, regardless of their location in the visual field (peripheral or peri-foveal), and the results provide the first evidence of a co-variation between modified brain activity and behavioural enhancement in this sensory-deprived population.

Investigating Neural Substrates of Visual Motion Sensitivity in Deaf Individuals
The aim of this thesis has been to explore neural substrates of enhanced far-peripheral visual motion processing in congenitally deaf adults. To do this, psychophysical measures were used as well asExpand
Effect of Exogenous Cues on Covert Spatial Orienting in Deaf and Normal Hearing Individuals
The deaf showed a higher cueing effect for the ocular responses than the normal hearing participants, however, there was no group difference for the manual responses, suggesting that the deaf may orient attention faster to targets. Expand
Enhanced reactivity to visual stimuli in deaf individuals.
The findings reveal that enhanced reactivity to visual stimuli in the deaf cannot be explained only by faster orienting of visual attention and can emerge for central as well as peripheral targets. Expand
