Sustained attention and the experience of flow.

The state of flow-often referred to as being "in the zone"-is characterized by the experience of deep, effortless concentration on the activity one is engaged in. While much of the flow literature seems to imply a tight link between flow and attention processes, relatively little work has assessed this question empirically. In the present study, we explored how the experience of flow relates to behavioural performance on the Sustained Attention to Response Task (SART). Flow was indexed at the state level using thought-probes and at the trait level via questionnaires. The main finding was that those who experienced more state-level flow during the SART made fewer commission errors during the task, indicating that flow is linked to better sustained attention. Interestingly, the correlation between flow and sustained attention performance was found to increase in the second half of the task. While trait flow was not related to SART performance, it was found to be predictive of state flow during the task, such that those who tended to experience higher levels of flow in their everyday lives also experienced more flow during the experiment.
