Shinzen Young's take on technological aids to meditation

Shinzen Young has pondered on the usefulness of technological aids to meditation:  https://www.shinzen.org/how-to-enlighten-the-world/

He posits four assumptions to simplify the discussion.  Embedded in these assumptions is the idea that there are switches in the brain that can turn off and on or dim the self makes me uneasy.  This seems to push the concept of neural correlates for states of mind a tad too far.  I would hold, along with many theorists in cognitive science (Clark, O'Reilly, Chalmers, Hutto, Chemero, Varella, Thompson, Noe), that the mind is more than the brain, that it is extended, situated, enacted and embodied and includes language, cultural and social practices, tools and technology.  Why is this relevant and not just a quibble?  Because working on the brain in abstraction without taking all these extensions into consideration will not likely lead to the kind of results that Shinzen Young foresees.  

I appreciate that he sees that the "conceptual content" of practice is one of the necessary components of a technological approach to aiding meditation.  I have noticed in my experiences with clinical neurofeedback that people sometimes just want to fix their brains without altering their approach to life and what perpetuates the dysfunction that led them to seek treatment.  Similarly, with meditation, it is essential to alter perspectives and attitudes.  Traditionally sila (wholesome conduct) is the foundation of the path to liberation.  The "techno-boosts" that he talks about are potentially accelerants rather than replacements of meditation practice.

I am not sure that lesions (even reversible ones) are the path to arhatship, and zapping the brain (as opposed to measuring it and getting feedback) does not appeal to me.  Whatever technologies we use for aiding meditation should be well-understood and safe.  The virtue of biofeedback in general and EEG neurofeedback in particular is that they have been around for a long time, they are non-invasive and, even when unwanted effects occur (and they can), they can be easily reversed or the effects simply fade away with time if they are not reinforced.

Meditation research website

Dr. Peter Malinowski of the Liverpool John Moores University has a website and blog devoted to psychological studies of meditation and mindfulness : http://meditation-research.org.uk/.  

"My aim is to share some of my thoughts on current developments regarding the science of meditation and also to inform about the meditation research carried out in our group in the School of Natural Sciences and Psychology at Liverpool John Moores University."

TED talk on wearables

Vandrico's CEO, Gonzalo Tudela, did a TedxTalk on wearable technology in 2013:

Interesting:  As much as wearable technology is potentially revolutionary, his projection of the adoption of it (50% of the population using wearable technology by February, 2015) appears to be (more than) a bit off.

Finger temperature and electrodermal response-- what they can tell us.

Frank and Mary Deitz were pioneers in the development of biofeedback systems. Their F1000 was one of the first relatively affordable and robust systems that integrated EEG, EMG, heart rate variability, respiration, temperature, and electrodermal response (EDR).

The attached chart was developed by them to show the relationship between measures of finger temperature and EDR, both of which indicate what is going on at the autonomic level.  By combing these two measures, it is possible to obtain a great deal of information about how someone is responding physiologically and, by inference, psychologically.

For instance, I have regularly asked clients to meditate on the breath and recorded their finger temperature and EDR.  Usually, the first time around, before they have practiced, what appears is rather erratic.  However, after a week or two of practice, I begin to see what to me is a relaxation response as they meditate.  Their finger temperature increases and their EDR decreases, but they remain responsive to thoughts or sensations that occur to them and to environmental events.  What this suggests, in accordance with the chart, is that they have an open circulatory system and a quiet, but still responsive, arousal system

When I have used these measures with clients who have practiced open monitoring with noting, a slightly different profile emerges.  Their temperature increases. but the EDR varies, presumably in response to their noting activity.  This suggests that while they are relaxed, as indicated by the increase in finger temperature, they are actively engaged and responsive to what is occurring to them.

Biosignals and the quantified self

Here is a Ted talk and an interview with Fu-Chiek Hsu of Op-Innovations, a company that makes affordable and versatile biosignal devices (more about this later).

This is a good introduction to the whole idea of measuring biosignals:  https://www.youtube.com/watch?v=4BLUXKOSfZ4

This provides a more informal and very insightful discussion of why it is useful to use biosignal devices:  https://www.youtube.com/watch?v=F8dHM4jzCTY

Musing--the problem with feedback

I plan a series of reflections, not so much on the Muse specifically, but on the issues that it and other similar devices raise.  This first musing is on the issue of feedback during meditation, especially auditory, which is used in the Calm app.

Ideally, there would be no need for feedback when we meditate.  We should be able to notice when our mind is focused and when it is distracted.  But this requires practice, and, even with practice, it is sometimes difficult to maintain the appropriate focus and awareness.  So this is where devices such as the Muse might prove helpful.

However, the biggest issue with using feedback technologies with meditation is that certain types of feedback can actually interfere with the activity they are designed to assist.

Let's assume we are doing focused attention meditation on the breath.

If I am remaining focused and not wandering, having any kind of feedback is likely to interfere with my focus.  If I am truly focused on the breath, I should be aware that I am focused on the breath.  I really don't need positive reinforcement.  On the other hand, if my mind is wandering and not focused, I may need to be alerted to this fact, reminding me that I should resume attention to the breath.  Over time, I may become more sensitive to the wandering and more able to readily return to the breath without the warning.

Auditory feedback is a readily available form of feedback, especially when we are already listening to instructions from the app via headphones or speakers.   However, it is common sense that attention to external stimuli such as sound will conflict with attention to the breath.  Whereas attention to the breath activates the interoceptive cortex (Farb et al, 2013), sound activates the auditory cortex.  If my mind is wandering anyway, this auditory "distraction" should not pose a great difficulty.  However, it should be momentary and only repeated long enough for me to recognize that I must redirect my attention.  If the auditory feedback is anything more than a quick reminder, it is likely to become a problem.

The Calm app provides different forms of auditory feedback.  Both the wind and the waves are giving feedback about the degree to which the mind is active.  The wind supposedly represents current activity, whereas the waves represent activity over a more extended time-frame.  Both the wind and waves vary in intensity and are continuous rather than discrete sounds.  The birds are supposed to represent a calm mind, and they reward you for maintaining calm over a period of time.  If I hear any of these sounds, they are very likely to become items of interest in themselves, thereby distracting me from focusing on the breath.  Also this kind of feedback is likely to stimulate evaluation and judgement--"I am doing well," "I am not doing well," and so on.

Whether different forms of feedback would make a difference or not remains to be seen.  Haptic feedback (see http://www.arcwearables.com) might cause less conflict than auditory feedback, for instance.  On the other hand, with auditory feedback it might be possible to provide more differentiated feedback that sensitizes the user to the type of activity that is going on.  In which case the feedback would not so much function as a warning (wind and waves) or as positive reinforcement (birds), but as information about what is going on.

These issues challenge the concept of using a device such as this as a meditation aide.  It is to be hoped that appropriate research will be done to determine whether the Muse (and other devices like it) can be useful for the purpose of assisting meditation.
