Investigating spatial attention changes across the lifespan with EEG and tDCS
Young adults typically display a processing advantage for the left side of space (“pseudoneglect”) but older adults show either no strongly lateralised bias, or a preference towards the right. At present there is very little neuroimaging evidence to show how this change is represented at a neural level, nor is it clear if such age-related changes may be ‘compensated for’ with non-invasive brain stimulation. I will present recent findings from our laboratory showing that pseudoneglect can be reliably measured over different populations/ timescales and tasks, and that its neural correlates shift with age. I will also discuss a possible altering of these spatial biases with transcranial direct current stimulation (tDCS) and a link between pseudoneglect and driving performance across the life span.
