Mind wandering and stress: When you don't like the present moment.

ABSTRACT: Buddhist philosophy and existing empirical evidence suggest that being engaged in-and accepting-the present moment is associated with greater well-being. However, engaging with the present moment experience and ignoring unwanted thoughts is difficult given the nature of our minds and the competing demands for our attention. This may be especially true when experiencing psychological stress, during which acceptance of current experience may be particularly difficult. This study examines inter- and intraindividual variability in how psychological stress influences daily mind states, and how mind states are related to affect. For 21 days, women (n = 183; half chronically stressed, half low-stress controls) reported levels of mind wandering, engagement with and rejection of their current experience, positive and negative affect, and quality of connection to their partner. Women under chronic stress reported more evening mind wandering, less engagement, and more rejection of the moment, compared to low stress controls. These mind states were in turn associated with more negative evening mood. Daily contextual factors, specifically, having a stressful event (objectively coded) and quality of connection with spouse that day (a known stress buffer), influenced evening mind states. Results provide evidence that chronic and daily psychological stress interfere with daily presence while positive social connection enhances presence in the moment.

Project description:A significant body of literature supports the contention that pupil size varies depending on cognitive load, affective state, and level of drowsiness. Here we assessed whether oculometric measures such as gaze position, blink frequency and pupil size were correlated with the occurrence and time course of self-reported mind-wandering episodes. We recorded the pupil size of two subjects engaged in a monotonous breath counting task while keeping their eyes on a fixation cross. This task is conducive to producing mind-wandering episodes. Each subject performed ten 20-min sessions, for total duration of about 4 h. Subjects were instructed to report spontaneous mind-wandering episodes by pressing a button when they lost count of their breath. After each button press, subjects filled in a short questionnaire describing the characteristics of their mind-wandering episode. We observed larger pupil size during the breath-focusing period compared to the mind-wandering period (p < 0.01 for both subjects). Our findings contradict previous research showing a higher baseline pupil size during mind wandering episodes in visual tasks. We discuss possible explanations for this discrepancy. We also analyzed nine other oculometric measures including blink rate, blink duration and gaze position. We built a support vector machine (SVM) classifier and showed that mean pupil size was the most reliable predictor of mind wandering in both subjects. The classification accuracy of mind wandering data segments vs. breath-focusing data segments was 81% for the first subject and 77% for the second subject. Additionally, we analyzed oculometric measures in light of the phenomenological data collected in the questionnaires. We showed that how well subjects remembered their thoughts while mind wandering was positively correlated with pupil size (subject 1, p < 0.001; subject 2, p < 0.05). Feelings of well being were also positively correlated with pupil size (subject 1, p < 0.001; subject 2, p < 0.001). Our results suggest that oculometric data could be used as a neurocognitive marker of mind-wandering episodes.
