objectives: researchers have focused their attention on balance in the elderly because there is a significant correlation between balance and fall. therefore, it is very important to identify the factors that can affect elderly balance. the aim of this study was to investigate relation between sustained attention and balance in elderly. methods: this cross sectional study was conducted in 2013 ...

This study examined the effect of attention engagement to compound auditory-visual stimuli on the modification of the startle blink reflex in infants. Infants at 8, 14, 20, or 26 weeks of age were presented with interesting audiovisual stimuli. After stimulus onset, at delays defined by heart rate changes known to be associated with sustained attention or attention disengagement, blink reflexes...

OBJECTIVE To establish reliable procedures and normative values to quantify brainstem encoding of speech sounds. METHODS Auditory brainstem responses to speech syllables presented in quiet and in background noise were obtained from 38 normal children. Brainstem responses consist of transient and sustained, periodic components-much like the speech signal itself. Transient peak responses were a...

One finding in attention research is that visual and auditory attention mechanisms are linked together. Such a link would predict a central, amodal capacity limit in processing visual and auditory stimuli. Here we show that this is not the case. Letter streams were accompanied by asynchronously presented streams of auditory, visual, and audiovisual objects. Either the letter streams or the visu...

BACKGROUND Sustained attention (SA) is important to task performance and development of higher functions. It emerges as a separable component of attention during preschool and shows incremental improvements during this stage of development. AIMS The current study investigated if auditory and visual SA match developmental level or are particular challenges for youth with DS. Further, we sought...

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 -...
