Recently, my FS101 students and I listened to an All in the Mind podcast discussing clinical, cognitive, and neuroscience investigations of meditation and, in particular, mindfulness (See Entry Here). One of the most intriguing ideas discussed in the podcast was the idea that mindfulness could actually increase and focus attention. If this is the case, mindfulness training could have several applications to the classroom. One way to examine this idea further might be to examine attentional gains in people who are trained in meditation.
Turns out that a team of researchers has actually begun to tackle these issues, and Scientific America's Street Science summarizes this research nicely.
In addition, you can read the abstract for the group's most recent publication by reading more:
Brefczynski-Lewis, J. A., Lutz, A., Schaefer, H. S., Levinson, D. B., & Davidson, R. J. (2007). Neural correlates of attentional expertise in long-term meditation practitioners, Proceedings of the National Academy of Sciences USA, 104, 11483-11488.
Meditation refers to a family of mental training practices that are designed to familiarize the practitioner with specific types of mental processes. One of the most basic forms of meditation is concentration meditation, in which sustained attention is focused on an object such as a small visual stimulus or the breath. In age-matched participants, using functional MRI, we found that activation in a network of brain regions typically involved in sustained attention showed an inverted u-shaped curve in which expert meditators (EMs) with an average of 19,000 h of practice had more activation than novices, but EMs with an average of 44,000 h had less activation. In response to distracter sounds used to probe the meditation, EMs vs. novices had less brain activation in regions related to discursive thoughts and emotions and more activation in regions related to response inhibition and attention. Correlation with hours of practice suggests possible plasticity in these mechanisms.
As FS101 has ended, this blog has recently changed its look. Instead of being a blog primarily derived from and for the first year seminar, the blog will now serve as a portal for the FS101 Archive. In addition, Psych 440 (Language & Social Cognition) entries will begin soon. The Cognitive Group will also find entries of interest regarding our meetings and recent research of interest from cognitive psychology. Finally, there will also be entries regarding the work in my lab including updates about our language production studies and the projects being conducted by the senior comp group.
First, congratulations to everyone for a great semester! I think you've all done an excellent job finding interesting stories, carefully reflecting on the lessons to be learned from these stories, and sharing your thoughts in a respectful, enthusiastic way. I've enjoyed working with all of you this semester and have really looked foward to reading your blogs each week.
