In 2002, Fan and his colleagues developed the Attention Network Test (ANT), a cognitive tool that provides a score for each of the attentional networks (alerting, orienting, and executive functioning). Since publication, this study has been cited over 3,500 times. The authors state one of the indicated uses of this tool is to measure how different interventions, both behavioral and pharmacological, influence the networks of attention. The present review focuses on this premise and investigates how various aspects of lifestyle differently impact the networks of attention. Whether trying to optimize the attentional networks to improve cognitive performance, or to prevent the cognitive decline that occurs with age, this review summarizes what practices promote efficiency within the alerting, orienting, and executive functioning networks. The specific areas of lifestyle this review focuses on are meditation, exercise, drug use, sleep, and environmental or social factors.
