TRI task-related interference, SART Sustained Attention to Response Task, DSSQ Dundee Stress State Questionnaire (post-task retrospective report of TRI frequency); Executive Control = factor scores from a confirmatory factor analysis of four cognitive performance measures (see text for details); Distract-Restless = z-score composites of seven questionnaire measures of Distractibility and Restlessness (see text for details); Pos.-Constructive = z-score composites of four questionnaire measures of Positive-Constructive Daydreaming (see text for details)
