As people get older, they tend to perform many activities more slowly and less accurately. We walk to the shops more slowly; we become more forgetful; we do not hit a golf ball as far in our 60s as we did in our 20s. Executive function is responsible for high-level cognitive operations, including planning, task management, working memory (WM), and inhibitory control (IC). A large body of behavioral research has focused on the effect of natural aging on executive function and has observed age-related deteriorations across a range of cognitive domains including WM and IC (e.g., Anderson et al., 2012; Heilbronner and Münte, 2013). It has been claimed that the natural aging process adversely affects saccadic eye movement functioning (Dowiasch et al., 2015), with the voluntary control over saccadic eye movements showing less resilience to aging (Peltsch et al., 2011). The natural process of aging, however, does not inevitably lead to cognitive decline, and the extent of this cognitive decline varies across tasks and individuals (Friedman et al., 2008; Park and Reuter-Lorenz, 2009; Crawford et al., 2013). Numerous studies have described the effects of aging on saccadic eye movement performance, but with clear inconsistencies; saccade parameters such as reaction times and error rates have been correlated with aging (Abel and Douglas, 2007; Peltsch et al., 2011), whereas, others have shown no difference between older and younger participants (Eenshuistra et al., 2004; Pratt et al., 2006). Clearly, further research is required in order to fully understand the neurocognitive changes involved in human aging. There have been several attempts to locate the decline of specific cognitive operations in aging. However, previous research has often relied on complex tasks with multiple interacting cognitive elements (Rabbit, 2005); therefore in this study we have turned to the well characterized antisaccade task (AST). The current experiment is an attempt to clarify whether, during the aging process, IC, WM, or both processes are associated with the decline in AST performance, which has been previously observed across the literature.
