Mind-body Awareness Training and Brain-computer Interface

Carnegie Mellon University231 enrolled

Overview

Mind-Body Awareness Training (MBAT), in the forms of various yoga and meditative practices, has become increasingly prevalent due to an increase in awareness of the potential health benefits, and improvements in concentration that this training can provide to practitioners. In the present study, the role of Mind-Body Awareness Training (MBAT) in the initial learning of a sensorimotor (SMR) based Brain-Computer Interface (BCI) is being investigated. The hypothesis is that MBAT will improve performance in SMR based BCI.

In this protocol, the following hypothesis will be tested; namely that MBAT including the verified mindfulness based stress reduction (MBSR) course will improve the ability for subjects to concentrate on the control of the SMR thus improving the performance of BCI. Subjects will be recruited for short term MBAT and then undergo BCI training. The performance of subjects with MBAT will be compared with those without MBAT to test the hypothesis. Procedures involved include a standard 8-week MBSR course, and an EEG brain noninvasive brain computer interface study.

Outcomes

Primary Outcomes

BCI Performance Change From Baseline

This outcome is related to the sub-study to investigate the effect of the MBSR on BCI learning. During the course of the sub-study over approximately 6 months/cohort of participants, participant learning over time during the course of study will be examined in terms of performance change after the intervention as well as across sessions, with a positive number representing an increase, and a negative number to represent a decrease. The percent valid correct (percent correct over valid trials) metric will be used to evaluate learning.

Time frame: 6 months for each participant.

Breath Counting Task

This outcome is related to the sub-study to investigate the effect of the MBSR on BCI learning. The breath-counting task will be used to measure the participants' mindfulness. Specifically, participants will be asked to count their breaths in cycles of nine (inhale and exhale counting as one) for 18 minutes, pressing one button for the first eight breaths, and a second button for the ninth. Breath counting accuracy is quantified as the number of correctly labeled breath cycles divided by the total number of cycles. The breath-counting accuracy for pre and post-intervention will be used.

Time frame: 6 months for each participant.

Survey Results and Correlation With BCI Performance

In the first session, participants are asked to complete two surveys to measure one's level of mindfulness before the BCI experiment. In both surveys, a higher score indicates a higher level of mindfulness: Survey 1: The Freiburg Mindfulness Inventory (FMI), with 14 statements, such as "I am open to the experience of the present moment". Participants are asked to use a 1-4 scale to indicate how often they have such an experience. The FMI score is calculated by summing up the answers to each question with a proper re-code of one question. FMI score range (minimum to maximum): 14 to 56. Survey 2: Day-to-Day Experiences, with 15 questions, such as "I find it difficult to stay focused on what's happening in the present". Participants are asked to use a 1-6 scale to indicate how often they have such an experience. The Mindful Attention Awareness Scale (MAAS) is calculated by averaging answers to each question in this survey. MAAS score range (minimum to maximum): 1 to 6.
