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.
