One of the most potent—and, outside therapy, little used—antidotes to depression is seeing things differently, or cognitive reframing. It is natural to bemoan the end of a relationship and to wallow in self-pitying thoughts such as the conviction that "this means I'll always be alone," but it's sure to thicken the sense of despair. However, stepping back and thinking about the ways the relationship wasn't so great, and ways you and your partner were mismatched—in other words, seeing the loss differently, in a more positive light—is an antidote to the sadness. By the same token, cancer patients, no matter how serious their condition, were in better moods if they were able to bring to mind another patient who was in even worse shape ("I'm not so bad off—at least I can walk"); those who compared themselves to healthy people were the most depressed.18 Such downward comparisons are surprisingly cheering: suddenly what had seemed quite dispiriting doesn't look all that bad.
Another effective depression-lifter is helping others in need. Since depression feeds on ruminations and preoccupations with the self, helping others lifts us out of those preoccupations as we empathize with people in pain of their own. Throwing oneself into volunteer work—coaching Little League, being a Big Brother, feeding the homeless—was one of the most powerful mood-changers in Tice's study. But it was also one of the rarest.
Finally, at least some people are able to find relief from their melancholy in turning to a transcendent power. Tice told me, "Praying, if you're very religious, works for all moods, especially depression."
REPRESSORS: UPBEAT DENIAL
"He kicked his roommate in the stomach . . ." the sentence begins. It ends, "... but he meant to turn on the light."
That transformation of an act of aggression into an innocent, if slightly implausible, mistake is repression captured in vivo. It was composed by a college student who had volunteered for a study of repressors, people who habitually and automatically seem to blot emotional disturbance from their awareness. The beginning fragment "He kicked his roommate in the stomach . . ." was given to this student as part of a sentence-completion test. Other tests showed that this small act of mental avoidance was part of a larger pattern in his life, a pattern of tuning out most emotional upset. 19 While at first researchers saw repressors as a prime example of the inability to feel emotion—cousins of alexithymics, perhaps—current thinking sees them as quite proficient in regulating emotion. They have become so adept at buffering themselves against negative feelings, it seems, that they are not even aware of the negativity. Rather than calling them repressors, as has been the custom among researchers, a more apt term might be unflappables.
Much of this research, done principally by Daniel Weinberger, a psychologist now at Case Western Reserve University, shows that while such people may seem calm and imperturbable, they can sometimes seethe with physiological upsets they are oblivious to. During the sentence-completion test, volunteers were also being monitored for their level of physiological arousal. The repressors' veneer of calm was belied by the agitation of their bodies: when faced with the sentence about the violent roommate and others like it, they gave all the signs of anxiety, such as a racing heart, sweating, and climbing blood pressure. Yet when asked, they said they felt perfectly calm.
This continual tuning-out of emotions such as anger and anxiety is not uncommon: about one person in six shows the pattern, according to Weinberger. In theory, children might learn to become unflappable in any of several ways. One might be as a strategy for surviving a troubling situation such as having an alcoholic parent in a family where the problem itself is denied. Another might be having a parent or parents who are themselves repressors and so pass on the example of perennial cheerfulness or a stiff upper lip in the face of disturbing feelings. Or the trait may simply be inherited temperament. While no one can say as yet just how such a pattern begins in life, by the time repressors reach adulthood they are cool and collected under duress.
The question remains, of course, as to just how calm and cool they actually are. Can they really be unaware of the physical signs of distressing emotions, or are they simply feigning calm? The answer to that has come from clever research by Richard Davidson, a University of Wisconsin psychologist and an early collaborator with Weinberger. Davidson had people with the unflappable pattern free-associate to a list of words, most neutral, but several with hostile or sexual meanings that stir anxiety in almost everyone. And, as their bodily reactions revealed, they had all the physiological signs of distress in response to the loaded words, even though the words they associated to almost always showed an attempt to sanitize the upsetting words by linking them to an innocent one. If the first word was "hate," the response might be "love."
Davidson's study took advantage of the fact that (in right-handed people) a key center for processing negative emotion is in the right half of the brain, while the center for speaking is in the left. Once the right hemisphere recognizes that a word is upsetting, it transmits that information across the corpus callosum, the great divide between the brain's halves, to the speech center, and a word is spoken in response. Using an intricate arrangement of lenses, Davidson was able to display a word so that it was seen in only half of the visual field. Because of the neural wiring of the visual system, if the display was to the left half of the visual field, it was recognized first by the right half of the brain, with its sensitivity to distress. If the display was to the right half of the visual field, the signal went to the left side of the brain without being assessed for upset.
When the words were presented to the right hemisphere, there was a lag in the time it took the unflappables to utter a response—but only if the word they were responding to was one of the upsetting ones. They had no time lag in the speed of their associations to neutral words. The lag showed up only when the words were presented to the right hemisphere, not to the left. In short, their unflappableness seems due to a neural mechanism that slows or interferes with the transfer of upsetting information. The implication is that they are not faking their lack of awareness about how upset they are; their brain is keeping that information from them. More precisely, the layer of mellow feeling that covers over such disturbing perceptions may well be due to the workings of the left prefrontal lobe. To his surprise, when Davidson measured activity levels in their prefrontal lobes, they had a decided predominance of activity on the left—the center for good feeling—and less on the right, the center for negativity.
These people "present themselves in a positive light, with an upbeat mood," Davidson told me. "They deny that stress is upsetting them and show a pattern of left frontal activation while just sitting at rest that is associated with positive feelings. This brain activity may be the key to their positive claims, despite the underlying physiological arousal that looks like distress." Davidson's theory is that, in terms of brain activity, it is energy-demanding work to experience distressing realities in a positive light. The increased physiological arousal may be due to the sustained attempt by the neural circuitry to maintain positive feelings or to suppress or inhibit any negative ones.
In short, unflappableness is a kind of upbeat denial, a positive dissociation—and, possibly, a clue to neural mechanisms at play in the more severe dissociative states that can occur in, say, post-traumatic stress disorder. When it is simply involved in equanimity, says Davidson, "it seems to be a successful strategy for emotional self-regulation" though with an unknown cost to self-awareness.
