Puzzles and Positive Moods

Puzzle-solving is such an ancient, universal practice, scholars say, precisely because it depends on creative insight, on the primitive spark that ignited the first campfires.

And now, modern neuroscientists are beginning to tap its source. 

Researchers at Northwestern University found that people were more likely to solve word puzzles with sudden insight when they were amused, having just seen a short comedy routine. 

“What we think is happening,” said Mark Beeman, a neuroscientist who conducted the study with Karuna Subramaniam, a graduate student, “is that the humor, this positive mood, is lowering the brain’s threshold for detecting weaker or more remote connections” to solve puzzles. 

Marcel Danesi, a professor of anthropology at the University of Toronto (says) “It’s all about you, using your own mind, without any method or schema, to restore order from chaos. And once you have, you can sit back and say, ‘Hey, the rest of my life may be a disaster, but at least I have a solution.’ ” 

Researchers at the University of Toronto found that the visual areas in people in positive moods picked up more background detail, even when they were instructed to block out distracting information during a computer task.

The findings fit with dozens of experiments linking positive moods to better creative problem-solving. “The implication is that positive mood engages this broad, diffuse attentional state that is both perceptual and visual,” said Dr. Anderson. “You’re not only thinking more broadly, you’re literally seeing more. The two systems are working in parallel.”

4 Ways to tell if your Relationship will Survive

John Gottman runs Seattle’s Love Lab. He believes he can accurately predict which couples stay together based on his lab studies, and his guesses largely revolves around supportive/destructive comments.  So destructive is the effect of certain behaviors on marital happiness, in fact, that he calls these behaviors The Four Horsemen of the Apocalypse.  The first horseman is criticism: "attacking someone's personality or character" rather than making some specific complaint about his or her behavior. The difference between saying, say, "I wish you had taken care of that bill" (a healthy and specific complaint) and "You never get the bills paid on time!" (a generalizing and blaming attack) is very significant to the listener. Criticism often engenders criticism in return and sets the stage for the second horseman: contempt. 

"What separates contempt from criticism," explains Gottman, "is the intention to insult and psychologically abuse your partner." Negative thoughts about the other come out in subtle put-downs, hostile jokes, mocking facial expressions, and name-calling ("You are such an idiot around money"). By now the positive qualities that attracted you to this person seem long ago and far away, and instead of trying to build intimacy, you're ushering in the third horseman. 

Defensiveness comes on the heels of contempt as a seemingly reasonable response to attack -- but it only makes things worse. By denying responsibility, making excuses, whining, tossing back counter-attacks, and other strategies ("How come I'm the one who always pays the bills?!"), you just accelerate your speed down river. 

Once stonewalling (the fourth horseman) shows up, things are looking bleak. Stonewallers simply stop communicating, refusing to respond even in self-defense. Of course, all these "horsemen" drop in on couples once in a while. But when a partner habitually shuts down and withdraws, the final rapids of negativity can quickly propel the marriage through whirlpools of hopelessness, isolation, and loneliness.

The bottom line is that flooding is physically uncomfortable, and stonewalling becomes an attempt to escape that discomfort. When flooding becomes chronic, stonewalling can become chronic, too. Eighty-five percent of the time the stonewaller (among heterosexual couples) is the man.  Though flooding happens to both men and women, it affects men more quickly, more intensely, and for a longer period of time.

Repair attempts are a way of talking about how you're communicating with each other. "Can we please stay on the subject?" "That was a rude thing to say." "We're not talking about your father!" "I don't think you're listening to me." Such statements, even when delivered in a grouchy or complaining tone, are efforts to interrupt the cycle of criticism, contempt, defensiveness, and stonewalling and to bring the conversation back on track. 

"In stable relationships," explains Gottman, "the other person will respond favorably: 'Alright, alright. Finish.' The agreement isn't made very nicely. But it does stop the person. They listen, they accept the repair attempt, and they actually change" the way they're relating. Repair attempts are "really critical," says Gottman, because "everybody screws up. Everybody gets irritated, defensive, contemptuous. People insult one another," especially their spouses. Repair attempts are a way of saying "we've got to fix this before it slides any deeper into the morass." Even people in bad marriages make repair attempts; the problem is, they get ignored. 

Training people to receive repair attempts favorably -- even in the middle of a heated argument -- is one of the new frontiers in relationship therapy. According to Gottman, "Even when things are going badly, you've got to focus not on the negativity but on the repair attempt. That's what couples do in happy marriages."  

Alan Atkisson writing in the New Age Journal (Sept/Oct 1994 issue)

Love is judicious

Love is not simply giving; it is judicious giving and judicious withholding as well. It is judicious praising and judicious criticizing. It is judicious arguing, struggling, confronting, urging, pushing and pulling in addition to comforting. It is leadership. The word “judicious” means requiring judgment, and judgment requires more than instinct; it requires thoughtful and often painful decision-making.

M Scott Peck, The Road Less Traveled

The last of the human freedoms

We who lived in concentration camps can remember the men who walked through the huts comforting others, giving away their last piece of bread. They may have been few in number, but they offer sufficient proof that everything can be taken from a man but one thing: the last of the human freedoms -- to choose one's attitude in any given set of circumstances, to choose one's own way. –Viktor Frankl (born March 26, 1905)

It was so much fun!

When Albert A. Michelson, the first person in the United States to win a Nobel prize in science, was asked at the end of his life why he had devoted so much of his time to measuring the velocity of light, he is said to have replied, “It was so much fun.’ And lest we forget, Einstein wrote his most influential papers while working as a clerk in the Swiss Patent Office. These and the many other great scientists one could easily mention were not handicapped in their thinking because they were not “professionals” in their field, recognized figures with sources of legitimate support. They simply did what they enjoyed doing.

When Loyalty at Work Becomes Harmful

Numerous examples and research show that overly loyal people are more likely to participate in unethical acts to keep their jobs and are also more likely to be exploited by their employer. These could manifest as being asked to work unreasonable hours or on projects or assignments unrelated to your role, or keeping things under wraps because it is in the company’s (read: family) best interest. We’re all in this together, so you have to play your part, right?

Studies show that employees who operate within a “familial culture” often fail to report any wrongdoing when they feel closer ties to the perpetrator. Feelings of fear the damage might cause to the perpetrator keep fellow employees quiet and complicit.

Joshua A. Luna, writing in the Harvard Business Review

Going with your Gut

Your feelings are a very important tool in understanding the world. Your unconscious mind does a lot of mental calculations that are more complex than your conscious mind is able to do. It can handle more information. That’s what comes back to your brain in gut feelings, hunches and intuitions. Those aren’t from nowhere. They're the result of complex calculations your brain did on an unconscious level, in conjunction with emotion. 

Leonard Mlodinow, quoted in GQ

 

Productivity struggles

E.B. White once wrote: “I arise in the morning torn between a desire to improve (or save) the world and a desire to enjoy (or savor) the world. This makes it hard to plan the day.” But in my research, I’ve found that productive people don’t agonize about which desire to pursue. They go after both simultaneously, gravitating toward projects that are personally interesting and socially meaningful.

Often our productivity struggles are caused not by a lack of efficiency, but a lack of motivation. Productivity isn’t a virtue. It’s a means to an end. It’s only virtuous if the end is worthy. If productivity is your goal, you have to rely on willpower to push yourself to get a task done. If you pay attention to why you’re excited about the project and who will benefit from it, you’ll be naturally pulled into it by intrinsic motivation.

Adam Grant, writing in the New York Times

Venting reinforces negative emotions

Think of our brain circuitry like hiking trails. The ones that get a lot of traffic get smoother and wider, with brush stomped down and pushed back. The neural pathways that sit fallow grow over, becoming less likely to be used. Kindergarten teachers are thus spot on when they say, “The thoughts you water are the ones that grow.” This is also true for emotions, like resentment, and the ways we respond to them, like venting. The more we vent, the more likely we are to vent in the future. 

Gail Cornwall & Juli Fraga writing in Slate

Burnout

I know the signs of burnout. It’s not like one morning you wake up, and you’re burnt. You’re noticing more emotional exhaustion. You’re noticing what researchers call depersonalization. You get annoyed with people more quickly. You immediately assume someone’s intentions are bad. You start feeling ineffective. I’d be lying if I said I wasn’t noticing those things in myself. I can’t be telling my students, “Oh, take time off if you’re overwhelmed” if I’m ignoring those signals. You can’t just power through and wish things weren’t happening. 

Yale cognitive scientist Laurie Santos, quoted in the New York Times

Lasting Happiness

Researchers have found that the happiness produced by acquiring material things such as cars, jewelry, and gadgets decreases over time. By contrast, the satisfaction associated with experiential purchases— like vacationing with a spouse or attending a sporting event with friends—increases as time moves forward, in part because we seldom do things alone. Elizabeth Dunn, a professor of who studies happiness says, “Going to a concert, taking a trip, any unique experience that is very special can make us feel more connected to people we love.”
