Mindfulness and Meditation Based Attentional Training


Meditation is a century year old practice that I experienced firsthand this week at the New York Insight Meditation Center. Clearly, the notion of meditation usually brings to mind an image of Buddha sitting at peace. Since it was my first time however, I didn’t know what to expect, and had a multitude of questions about the practice. Why’s the purpose of meditation? The ultimate aim? Are there different types of meditation? What are the advantages associated with meditation? The readings for this week shed light on several of these questions, and together with my experience in my first meditation session, gave me a much clearer sense of both the process and end goal of meditation. We begin with a brief overview of the readings for this week and follow with a description of the meditation session, with particular emphasis on its relationship to mind wandering.



Before going to the meditation session, I read up on the research concerning this practice, and I was surprised to find that meditation is a rather varied practice that had clear advantages. I always thought that the increased sense of peace associated with meditation came from simply resting the body more so than the mind. This week’s readings as well as my own meditation session refuted this conjecture. Indeed, the session included an emphasis on the power of the mind in focusing on the task at hand such as following the breath and relaxing certain areas of the body as well as in broader endeavors such as reaching acceptance.
Thus, one can say that “mindfulness,” as defined by Baer et. al. (2006), was an important component of my meditation session. In accordance with the instructor’s talk, Baer and his colleagues found that mindfulness, defined as “bringing one’s complete attention to the experiences occurring in the present moment, in a nonjudgmental or accepting way,” can be developed with regular meditation. Furthermore, the authors also mention that mindfulness can lead to increases in qualities such as awareness, compassion, and equanimity. In their study, the authors used questionnaires to measure awareness, nonjudgemental “present-moment observation and openness to negative experience,” and “acting with awareness…accepting without judgment.” The found that the results of the questionnaires demonstrated internal consistency and showed that mindfulness correlated such several other variables, thus making the questionnaires psychometrically promising tools.
Lutz et. al. (2008)’s report focused more on the practice of meditation itself rather than on a certain characteristic/result of  meditation. Specifically, Lutz and their colleagues defined two types of meditation, namely focused attention (FA) and open monitoring (OM) meditation. FA meditation, like its name suggests, refers to focusing thought on a selected object and maintaining attention only on the present task/object while minimizing distraction and intrusive thoughts. On the other hand, open monitoring (OM) meditation involves “non-reactively monitoring” thoughts as they occur from moment to moment, allowing the mind to wander as a means to experience and appreciate one’s “emotional and cognitive patterns.” Thus, FA meditation is more involved in training the mind whereas OM meditation allows us to experience the mind by accepting the thoughts that cross it.
Clearly, the characteristics of FA meditation (such as focus on one object or task) are reminiscent of vigilance and the characteristics associated with sustained attention. MacLean et. al. (2010) saw this connection and performed a study on whether FA meditation led to improvements in sustained attention. The authors found increased visual discrimination as well as improvements in vigilance/sustained attention tasks as a result of meditation training. These results suggest that intensive FA meditation involving attention on nonvisual perceptions such as breath indeed generalizes to improved visual perception during vigilance tasks. I found this to be particularly interesting because it suggests that meditation training resulted in an improvement of mind and not just an increased peace in body. I would be interested to see whether meditation leads to improved performance on other types of vigilance tasks not including visual perception.
Jensen et. al. (2012) addressed a possible confounding factor in MacLean et. al.’s 2010 study. Although the investigation had compelling results, Jensen questioned whether the improvements were actually the result of increased attention. Specifically, Jensen and colleagues propose that these improvements could have been the result of increased “attentional effort,” and thus reflect the subject’s willingness to focus attention on a selected object or during a vigilance task and not the subject’s ability to do so. In their study, they tested 48 healthy subjects without previous meditation training were assigned to groups with differing mindfulness (mindfulness-based stress reduction/MBSR and non-mindfulness based stress reduction/NMSR) and incentive levels. The premise is that the “incentive” group will have greater motivation and willingness to perform—and thus exhibit a greater attentional effort. The authors found that attentional effects of MBSR, NMSR, and the incentive groups were comparative, though slightly greater in the incentive group. However, only the MBSR group exhibited notable improvements in selective attention and an improved threshold for “conscious perception and visual working memory capacity.” Therefore, the authors argue that MBSR may contribute uniquely to attentiaonl improvements but further research on the effect of test effort is needed before one can make a conclusions such as that of MacLean et. al. In essence, Jensen’s study serves as a cautionary tale to account for the presence of confounding variables in the study of attention.



Clearly, after reading these reports and looking up interesting pictures of meditation, I had a conglomeration of different expectations for what my first meditation session would be like. Personally, in my mind, meditation reminds me of Rafiki (the wise old baboon) from the Lion King more than anything else. He meditates on a rock just before leading Simba to the vision of his father and motivating him to accept the past, move on, and embrace the future. If you can’t tell, Lion King was my favorite childhood Disney movie. And Rafiki was my favorite character. On to (real) meditation! The session began with sitting meditation, in which we assumed a restful sitting position and concentrated on our breath. This focus was paired with instructions to relax certain areas of our body in sequence. Occasionally, the instructor would ring the gong three times during our meditation session. I found this session to be a mixture of both FA and OM meditation, as defined in Lutz et. al. For instance, our instructor encouraged us to focus on our breath and to not let our minds stray or wander. However, he also encouraged us to let our thoughts pass through our minds one by one. Regarding mind wandering, he told us to “be gentle with yourselves;” because of the power of the mind, he said that mind wandering is inevitable, especially during a beginning meditation session. “When your mind wanders, just gently bring yourself back to the breath and focus on that.” Thus, I found it interesting that the session included both types of meditation. The second half of the session, and the one I found to be most interesting, was a discussion on the practice and benefits of meditation. Through personal anecdotes, our instructor elaborated on the power of meditation to foster acceptance and “clearing.” By focusing the mind and becoming one with the universal “self,” meditation helps us see the interconnectedness of everyone in society. In particular, he talked about how meditation led to positive changes in his life by enabling him to release the negativity and move on from tragic events and find peace and acceptance.
I found this week’s readings and in particular, this week’s meditation session, extremely informative both academically and personally. My experience this week helped me understand meditation in a broader light and shed light on how it could positively contribute to a more accepting and positive life.
