Mindfulness. It’s a word that’s been thrown out a lot in recent years. But what exactly is it? What does it entail? What does it do? Why is it so popular? Is it just another fad, popular now, only to fall off when we realize there’s actually nothing to it. If you just want quick, to-the-point answers, here you go, in order: a practice that can be trained; potentially many different things; great things for mental and physical health; likely due to the fact that it works; and no. If you want more detailed answers, read on.

Free Will: Is It Real Life? Is It Just Fantasy?

It’s been in the back of my mind to write this post for a while, but I had been putting it off. But as I was walking out of the gym the other day thinking about my class choreography, I realized how relevant this topic is to so many things, so it’s time for it. I was thinking about the strength training class I teach and how much I love the section where we work back (deadlifts, rows, flyes, etc.). It has become my favorite section of that class, in large part because I always play a Journey song. Then I began to realize how that has helped me—no, caused me—to enjoy Journey more (not that I didn’t enjoy them before, but I’ve been getting into them much more since I started teaching this format), and also how I really started to enjoy the back section more once I began to make a big deal about making it my thing to always use a Journey song. In short, I had a profound yet mundane epiphany: did I choose to start liking that section of class (or Journey) more? Or was this increased fondness somehow destined by my previous actions and decisions?

Physical Fitness for Psychical Fitness: The Mental Benefits of Exercise

~ D. R. Meriwether, Ph.D. ~ 2 Comments

Age-related cognitive decline is pretty much inevitable, especially now that people are generally living longer. While this decline in fluid intelligence (reasoning abilities) is complemented by an increase in crystallized intelligence (factual knowledge; see figure below), fluid intelligence helps us deal with many aspects of our daily lives (such as processing new information and solving problems), so it’s worth preventing its decline as much as possible. Thankfully, there are ways to do this. Continual learning and mental engagement (i.e., effortful mental engagement, not simple passive learning) are excellent ways to keep one’s mind sharp. But, perhaps one of the best ways is by doing something that also benefits us in other ways: exercise.

Easy Come, Easy Go: The Surprising Paradox of Task-Switching

What do pit orchestra and my dissertation have in common? Well, aside from the fact that I maybe read some relevant articles during the occasional rehearsal and/or show (or, more often the case, discovered that articles weren’t as relevant as I thought they might be), almost nothing…aside from one thing: task-switching. As a reed player, I have doubled for most of the shows I’ve done, meaning I play multiple instruments, usually in the clarinet and/or saxophone families, though I have done some flute (not my forte—but not my piano either). Though still playing music, when switching between instruments, I’m essentially switching between tasks (at least as psychologists would define task-switching), because I’m alternatingly applying different sets of rules (i.e., fingerings). When doing this, rules will inevitably be misapplied (i.e., I play the wrong note).

Shower Power: Demystifying the Experience of Shower Thoughts

~ D. R. Meriwether, Ph.D. ~ 4 Comments

Ironically, I did not think of the idea for this post in the shower. Instead, it happened during a conversation I had. I was talking with a woman, and near the end of the conversation, I mentioned how I process and think through things really well in the shower. She mentioned that she was the same way, and I think we were both delighted to hear that we weren’t alone in that. And, more than that, I’d wager that it’s actually a pretty common—and, let’s be honest, a pretty delightful—experience. And I think there are some valid psychological reasons for why. Here goes.

Reading with Your Mind in Mind: The Cognitive and Social Benefits of Literary Fiction

I read this article and it both aggravated and encouraged me. Overall, it was a very encouraging article, touting the importance of a liberal arts education. But, several parts aggravated me, namely, the reported views of tech company founders/executives regarding the humanities—specifically, how some of these higher-ups think the humanities to be lesser disciplines than the STEM disciplines and, therefore, not worth a student’s while, such as this quoted view of Vinod Khosla: “If subjects like history and literature are focused on too early, it is easy for someone not to learn to think for themselves and not to question assumptions, conclusions, and expert philosophies.”

While I respect Khosla’s innovativeness and success, I must wholeheartedly disagree with this assertion. It is in the humanities where we are uniquely taught to think for ourselves (at least in certain ways) and to tackle unique problems. No, the humanities don’t teach all types of thinking (e.g., research via the scientific method), but how often do the sciences educate us in asking and answering important existential, ethical, or metaphysical questions? And indeed, because of these unique mindsets that are developed in the humanities, as the author goes on to say, these individuals are able to solve otherwise seemingly intractable problems…even in a STEM discipline like computer programming.

Music Is the Food of the Brain. Play On.

“Music […] gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything.”
Plato

I love music. I love listening to it. I love playing it. I love talking about it. I can be a bit snobbish about my preferences for it (but I’m working on that). But, really, music is music, and that makes it great. It can be enjoyed by people of all nations, for there is no language barrier in music. (Case in point: when I was in Berlin several years ago, I went to see Carmen. If you’re not familiar with that opera, it’s sung in French…which I don’t speak. Being in Berlin, the surtitles were in German…which I can’t read. Needless to say, I was clueless about the plot. But, I was still able to enjoy the music and the performance, both of which were stunning.) It brings people together for a common purpose of making or listening to something beautiful, and there is something so uniquely special in an ensemble of individuals playing together as one. Music speaks to our emotions and helps us express them in ways that our words can’t. It’s food for the soul.

It’s also food for the brain.

To Be and not to Be: The Quantum Nature of Consciousness

I’m not going to try to argue that consciousness arises from some mysterious quantum activity within the atoms that make up the brain’s neurons. As a scientist, I know better. As a cognitive scientist, I know that, although it is not fully understood how consciousness arises from neural activity, consciousness does indeed arise from that neural activity. No neural activity, no consciousness—simple as that. Also, from what little I know of physics, quantum phenomena are limited to subatomic particles (though atoms can sometimes act like quantum particles), so there’s no way that neurons, which are composed of cells, which are composed of molecules, which are composed of atoms, could behave quantumly. No. Neurons must obey the laws of classical mechanics, not quantum mechanics.

Also, as Matthew Francis, with warrant and good reason, exhorts in this post, it is often a grievous error to apply quantum models to other mysterious phenomena, noting that, when this is done, the person has either misunderstood quantum mechanics or the other phenomenon of interest. However, his exhortation is against those who argue that quantum mechanics is what underlies these other mysterious phenomena. It was never my intention to argue such a case for consciousness. As I said above, cognitive science tells us that’s not how consciousness works. So rather than argue that quantum processes give rise to consciousness, I will argue that quantum mechanics makes for an effective and compelling analogy for explaining how consciousness works. That is, perhaps thought functions not unlike a quantum particle and consciousness arises from brain function as a not wholly predictable process, similar to how quantum phenomena arise rather unpredictably from quantum particles.
