The Influence of Mindfulness Meditation Retreat on Attention to Internal Experience

February 12, 2023 updated by: University of Haifa
Although attention is thought to have a definitive functional role in mindfulness meditation training and its salutary mechanisms of action, extant empirical evidence is mixed and limited. In the proposed study, we propose to test whether 6 to 7-days mindfulness meditation retreats (N=90), relative to a wait-list control condition (N=45), will impact internal attentional processes or attention to internal experience (e.g., thoughts and bodily sensations); and whether these internal attentional change processes predict salutary outcomes of mindfulness meditation retreats. Participants will complete tasks designed to measure attention to internal experience before and then immediately following the retreat, as well as self-report measures of salutary outcomes before and 2-weeks post-retreat. Matched controls will complete the tasks at parallel time-points in the lab.

Study Overview

Detailed Description

Broadly, the investigators first aim is to assess whether mindfulness meditation retreat will yield significant improvement at post-relative to pre-retreat, compared to matched control, in each of these internal attentional processes: (i) enhanced ability to disengage from negative self-referential thoughts; (ii) reduced selection bias to negative self-referential thoughts; (iii) enhanced interoceptive attention and sensibility to a broader range of locations, intensities and hedonic tones of bodily sensations in response to negative and neutral self-referential thoughts; as well as (iv) enhanced mindful awareness during mindfulness meditation as expressed in the objects and temporal dynamics of mindful awareness. Second, the investigators will assess whether each of the aforementioned internal attentional change processes from pre- to post-retreat, will predict change from pre- to 2-weeks post-retreat in mindful awareness in daily living, mindfulness-related processes (e.g., decentering), and mental health. Third, investigators will assess whether previous meditation experience moderates these effects.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Mindfulness Meditation Retreat
6 to 7-days mindfulness meditation retreat
6 to 7-days mindfulness retreat (Vipassana/insight meditation). The retreats are held in silence and led by senior teachers with many years of experience in teaching meditation. The focus of the retreat is the practice of mindfulness meditation while sitting and walking. Retreats include focused attention and open monitoring mindfulness meditation practices. Each retreat has a similar practice schedule thus the amount and nature of formal practice is mostly the same.
No intervention, Matched control
Adults participants will be recruited from social media and local community of meditation practitioners, and will be matched to the retreat group by gender, age and level of experience in meditation.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Simulated Thought Paradigm - Digit Categorization Task
Time Frame: pre-intervention, immediately post-intervention
The Simulated Thought Paradigm integrated into the Digit Categorization Task will be used to measure change, from pre-intervention to post-intervention, in internal attentional disengagement from simulated negative and neutral self-referential thoughts to a digit categorization (odd or even) task. Attentional disengagement will be computed via difference in reaction time to respond to digit target between negative and neutral self-referential thoughts. A positive score reflects greater difficulty to disengage from negative vs. neutral stimuli.
pre-intervention, immediately post-intervention
Change in Simulated Thought Paradigm - Dichotic 1-Back Task
Time Frame: pre-intervention, immediately post-intervention
The Simulated Thought Paradigm integrated into the Dichotic 1-Back Task will be used to measure change, from pre-intervention to post-intervention, in internal selection between concurrent simulated negative and neutral self-referential thoughts. Biased selective internal attention will be computed via subtracting behavioral responding (e.g., accuracy) between concurrent negative and neutral self-referential thoughts. A positive bias score reflects greater selective attention to negative vs. neutral stimuli.
pre-intervention, immediately post-intervention
Change in Simulated Thought Paradigm - Body Map Task
Time Frame: pre-intervention, immediately post-intervention

pre-intervention, immediately post-intervention
Change in Mindful Awareness Task
Time Frame: pre-intervention, 0-2 days post-intervention
The Mindful Awareness Task is a behavioral paradigm will be used to measure change, from pre-intervention to post-intervention, in the objects and temporal dynamics of mindful awareness during mindfulness meditation. MAT scores include meta-awareness, quantified as the frequency of meta-awareness (i.e., awareness of the processes in consciousness); mindful awareness of body, mind, thoughts, pleasant and unpleasant hedonic tone, quantified as the frequency of mindful awareness of these experiential objects; mindful awareness time, quantified as the amount of time each participant engages in mindful awareness (in seconds); sustained mindful awareness, quantified as the average amount of time each participant sustains mindful-awareness without significant interruptions (in seconds); and latency to re-engagement in mindful awareness, quantified as the average amount of time it takes each participant to re-engage in mindful awareness following the onset of mindless states (in seconds).

Other Outcome Measures

Measure Description
Time Frame
Previous Meditation Experience Interview
Time Frame: pre-intervention
A structured phone interview assessing previous experience in meditation retreats and previous regular meditation practice. During this interview, participants are asked to specify each meditation retreat in which they participated in the past, and their previous regular meditation practice. The following scores are computed based on participants' reports: total number of days in mindfulness meditation retreats and total number of months and hours of previous regular mindfulness meditation practice outside of retreats (at least once a week). Similar scores are computed for previous retreats and regular practice of meditation styles that do not emphasize the cultivation of mindfulness (e.g., transcendental meditation).
