It takes self-discipline to follow through with those larger tasks that return only a delayed sense of gratification, and I think that’s a learned ability. And in that regard, it was probably a good thing that my formative years were spent in a conscientious home environment. But a compelling sense of curiosity combined with an ability to hyper-focus on tasks have also helped me to keep moving forward throughout my life, though perhaps in fits and starts.
Regardless, my attention doesn’t easily span the necessary duration of most forms of passive presentation… TV, movies, theater — or lectures, conferences, and ceremonies. I’m a doer as opposed to a scholar. And in that regard, I’ve always had to employ some strategies to make it through the tedious parts.
During my undergraduate years of college, my favorite study spot wasn’t any of the usual student lounges. Instead, I preferred the game room in the student center, an obnoxiously loud environment. Powered by a small bucket of strong coffee, I would situate myself at a corner table and proceed to concentrate on the memorization of some sequence or system while the external world faded into silence.
The focus usually lasted for about an hour before my surroundings would begin to leak back into awareness, signaling that the neurotransmitters needed a recharge. And that was where the game room came into the picture. Sometimes, whole days would pass like that, oscillating back and forth in heaving waves of intense focus punctuated by utter distraction. It may seem inefficient, but it’s always worked for me.
When I mentioned this to a psychologist friend of mine, she commented that I was describing “ADD,” or Attention Deficit Disorder. And she also remarked that ADD is at least in part genetic, apparently associated with a gene called “DRD4-7R.” Don’t ask me what any of this means, other than that the gene is repeated seven-times. But the gist of our conversation was that it’s a naturally occurring genetic characteristic that probably served our hunter-gatherer ancestors in their quests for food and survival.
DRD4, apparently moderates dopamine, a chemical messenger in the brain important to learning and reward (pleasure). And according to my friend (and some articles if since read), people with the “7R” variant generally need more stimulation to feel dopamine’s pleasurable effect.
Perhaps predictably, studies show that the DRD4-7R gene correlates with risk-taking behaviors, exploration, habituation (becoming quickly bored with things), desire for novelty and adventure, sex, and drugs (and rock-n-roll?). And it’s also closely associated with attention deficits and hyperactivity. People with 7R just need a bit more of a jolt to get the pleasure center firing.
So there it is — perhaps I’m just a natural hunter-gatherer, built for exploring an unknown forest, focused intently upon my prey as it approaches, and then… Except, I’ve never been much for killing things myself, and I usually get my food at one of the local markets. And then there’s that whole “civility” thing demanded by societies in general.
Natural selection evidently long ago resolved that problem for what now amounts to some eighty-percent of the world’s human population, with the “4R” variation of the DRD4 gene. With fewer repeats, DRD4-4R has less of a mediation effect on dopamine, allowing it to be more easily felt. And that’s probably a good thing for the settler who needs to stay in pretty much the same place to tend the farm, or to herd the cattle — or to work in an office, or to write a book.
The advantage of an adaptation is relative to environment, so it would seem there’s something intrinsically well-adjusted about a civilized person being satisfied, and in fact pleased, by the result
of a place in civilization. It’s like the descendants of some long-extinct species of wolf who lost enough of their instinctive wildness to benefit from a new social opportunity… perhaps first with a group of hunter-gatherers.
But a hunter-gatherer in a settler environment needs a great deal of self-discipline. Most risk-taking behaviors are by definition illegal in civil societies, making it difficult for a hunter-gatherer to get that dopamine feeling without also getting into trouble of some sort or another. Like wolves among humans, settlers don’t have much use for distracted non-conformists. So nowadays the 7R’s have to satisfy their instincts in the wilderness, or listening to loud music, or riding motorcycles…at least in public.
Past that, they’re confined to lurking in the shadows, skirting the poorly lit edges of civilization while their socially better-adapted brothers and sisters rest well-fed and content next to the campfires. Eventually, they’ll wander off — it’s in their genes. But sometimes, hunger calls even the wolf from the forest.
