Dataset used for the study Eye gaze and Ageing

Dataset used for the study Eye gaze and Ageing: Selective and combined
effects of working memory and inhibitory control, published in Frontiers
in Human Neuroscience, in press. by TJ. Crawford, ES. Smith and D Berry.
The current study assessed inhibitory control and working memory processes
underpinning saccadic eye movements in young and older participants. This
was achieved with three experimental conditions that systematically varied
the extent to which working memory and inhibitory control were taxed in
the antisaccade task; a memory-guided task was used to explore the effect
of increasing the working memory load; a Go/No-go task was used to explore
the effect of increasing the inhibitory load; a ‘standard’ antisaccade
task retained the standard working memory and inhibitory loads. Saccadic
eye movements were also examined in control condition: the standard
prosaccade task where the load or working memory and inhibitory control
was minimal or absent. Saccade latencies, error rates and the spatial
accuracy of saccades of older participants were compared to the same
measures in healthy young controls across the conditions. The results
revealed that ageing is associated with changes in both inhibitory control
and working memory. Increasing the inhibitory load was associated with
increased reaction times in the older group, whilst the increased working
memory load and the inhibitory load contributed to an increase in the
anti-saccade errors. These results reveal that ageing is associated with
changes in both inhibitory control and working memory. Dataset embargoed
until 1st January 2018.
