Cognitive control is required for flexible responses in changing environments and can be assessed by measuring antisaccade error rate. Considerable variance in antisaccade error rate is observed in healthy participants, which motivated the current study to explore the cognitive factors affecting antisaccade performance. Relationships exist between prosaccade latency and antisaccade error rate, with faster prosaccade latencies linked to more antisaccade errors. Individual differences in working memory also impact saccadic performance. The current study tested the relationships among prosaccade latency, antisaccade error rate, and working memory in 153 healthy participants. Correlation and multiple regression analyses demonstrated that prosaccade latency predicted antisaccade error rate, and working memory moderated this relationship. These results may help elucidate individual differences in cognitive control among healthy individuals.
