Children with neurofibromatosis type 1 are at increased risk for the development of attention problems relative to their unaffected peers. Previous studies have reported deficits in sustained auditory attention, but other aspects of attention, including sustained visual attention, divided attention, response inhibition, and selective attention, have not been consistently documented. In the pres...

Dyslexia and attentional problems are often comorbid. This raises the question whether reading deficits might etiologically follow from attentional difficulties, a hypothesis that has been proposed in regard to visuo-spatial attention deficits. This visuo-spatial attention deficit hypothesis would predict that attention deficits should be specific to dyslexia. However, it is here estimated that...

Impaired attentional processing of negative facial expressions is prominent in schizophrenia and has been shown to be associated with patients' social dysfunctions. However, little is known about when and which specific attention deficits influence social functions. Given the dynamic feature of attention, it is necessary to investigate the attention deficits in negative emotional processing unf...

The pulvinar is an important structure for visual attention function. Spatial and temporal attention was examined in three patients with varying pulvinar lesions. Spatial and temporal deficits were dissociable. The patient with anterior damage showed strong spatial but not temporal attention deficits, while the patient with posterior damage showed clear temporal attention deficits, but much red...

objective: the purpose of this research was to study the cognitive functions in patients with methamphetamine-induced psychosis (mip) in comparison with schizophrenia patients and normal subjects. method: this was a cross-sectional study, 30 patients with mip, 30 patients with schizophrenia and 30 normal individuals were selected via convenient sampling and were matched on age, sex and educatio...

Impairments in selective attention have been proposed as an explanation for the source monitoring deficits in schizophrenia. We tested this hypothesis by examining correlations between source monitoring variables and a measure of selective attention (from the Stroop Test) in 54 individuals with schizophrenia subjects and 42 normal controls. We did not find significant correlations between sourc...
