This study investigated the effects of kinesthetic stimuli on brain activities during a sustained-attention task in an immersive driving simulator. Tonic and phasic brain responses on multiple timescales were analyzed using time-frequency analysis of electroencephalographic (EEG) sources identified by independent component analysis (ICA). Sorting EEG spectra with respect to reaction times (RT) ...

Introduction. The symptoms that comprise inattentive behaviour in ADHD include problems with focusing on a task and sustaining attention over a long period, even in advantageous external conditions. There is also a characteristic excessive distractibility under the influence of other, unimportant stimuli. Thus attention processes are one of the main variables which form the clinical picture of ...

Sustained counting (or temporal numerosity judgements) has been one of the key means of investigating anterior attentional processes. Forty-three patients with localised lesions to the frontal lobes were assessed on two tests of the ability to count the number (8-22) of stimuli presented at either a slow (roughly one per 3 sec) or fast (roughly three per sec) rate. Patients with lesions to the ...

Sustained attention has been shown to be vulnerable following traumatic brain injury (TBI). Sleep restriction and disturbances have been shown to negatively affect sustained attention. Sleep disorders are common but under-diagnosed after TBI. Thus, it seems possible that sleep disturbances may exacerbate neuropsychological defi cits for a proportion of individuals who have sustained a TBI. The ...

background: sustained visual attention is a prerequisite for learning and memory. the early evaluation of attention in childhood is essential for their school and career success in the future. the aim of this study was to design, development and investigation of psychometric properties (content, face and convergent validity and test-retest and internal consistency reliability) of the computer -...
