Sitting with it: An investigation of the relationship between trait mindfulness and sustained attention

BackgroundSustaining attention for extended periods of time is associated with negative affect and this increase in negative affect is related to poorer task performance. Trait mindfulness has been shown to be associated with better sustained attention performance. This may be because trait mindfulness is associated with better attention ability or better emotion regulation ability.AimsThe present research aims to replicate previous findings and better understand why trait mindfulness is associated with better sustained attention performance.MethodParticipants responded to self-report questionnaires assessing their trait mindfulness, attentional control, and experiential avoidance. Next, participants performed a sustained attention task, during which they also reported their subjective feelings of discomfort and boredom. Finally, participants reported their retrospective discomfort and boredom after the task.ResultsWe replicated and extended previous findings by showing that the relationship between trait mindfulness and sustained attention performance was mediated by negative affect experienced during the task. Moreover, the correlation between trait mindfulness and sustained attention disappeared when controlling for experiential avoidance, but remined when controlling for attention control.ConclusionOur results suggest that trait mindfulness is associated with sustained attention because of enhanced emotion regulation and that enhancing affective regulation would be an effective strategy for improving sustained attention performance.
