| Annotation | To investigate the effect of age and mood on saccadic function (i.e. quick, abrupt eye movement), the authors recorded prosaccades, predictive saccades and antisaccades from 238 cognitively normal, physically healthy volunteers aged 44 to 84. Mood levels were measured using the Satte-Trait Anxiety Inventory and Center for Epidemiological Studies Depression Scale inventories. Small but significant, positive relationships with age were observed for the mean latency and associated variability of latency for all types of saccades, as well as the anti-saccade error rate. Saccade velocity or accuracy was unaffected by age. Increasing levels of depression had a minor negative influence on the anti-saccade latency, whereas increasing levels of anxiety raised the anti-saccade error rate marginally. (RH). |
