Covert orienting of visual spatial attention in attention deficit hyperactivity disorder: does comorbidity make a difference?

Automatic orienting of visuospatial attention in Parkinson's disease.

The basal ganglia are involved in not only motor behavior, but also other more cognitive processes, such as attention. We tested Parkinson's disease (PD) patients in a task that measures reflexive orienting of spatial attention. Seven patients with idiopathic PD and eight control subjects performed a covert orienting task where spatial attention was directed by means of exogenous cues (luminanc...

Deficits in the covert orienting of attention in children with Developmental Coordination Disorder: does severity of DCD count?

Children with Developmental Coordination Disorder (DCD) show deficits in the covert orienting of visuospatial attention, suggesting an underlying issue in attentional disengagement and/or inhibitory control. However, an important theoretical issue that remains unclear is whether the pattern of deficits varies with DCD severity. Fifty-one children with moderate DCD (MDCD), 24 children with sever...

Towards a single trial detection of spatial covert visual attention for BCI

This paper discusses a time-dependent classification approach for single trial recognition of spatial covert visual attention for Brain–Computer Interface (BCI). Covert visual attention is a natural and intuitive mental task that does not require any external stimulation. The possibility to recognize it from single trials is essential for a future online close-loop BCI. Experimental results sho...

Impaired Shifting of Visuospatial Attention in Alzheimer’s disease as Shown by the Covert Orienting Paradigm: Implications for Visual Construction Disability

OBJECTIVE To investigate impaired shifting of visuospatial attention in Alzheimer's disease (AD) compared with age-matched controls. METHOD An attention shifting was examined in 20 AD patients and 10 age-matched normal subjects by choice reaction time (CRT) and covert orienting paradigm. Visuospatial functions tests were also performed. For covert orienting, a peripheral spatial cue method wa...
