Exploring eye movement analysis as a measure of selective visual attention in brain injured individuals.
OBJECTIVE
To investigate the utility of using a new method of assessment for deficits in selective visual attention (SVA).


METHODS
An independent groups design compared six participants with brain injuries with six participants from a non-brain injured control group. The Sensomotoric Instruments Eye Movement system with remote eye-tracking device (eye camera) and two sets of eight stimuli were employed to determine if the camera would be a sensitive discriminator of SVA in these groups.


RESULTS
The attention profile displayed by the brain injured group showed that they were slower, made more errors, were less accurate and more indecisive than the control group.


CONCLUSIONS
The utility of eye movement analysis as an assessment method was established, with implications for rehabilitation requiring further development.
