Put on a few extra pounds over Christmas? Wonder why you feel compelled to eat half a box of chocolates half an hour after finishing your second plate of turkey, dressing, mashed potatoes and gravy? Feel a little guilty?
Well, new research offers clues to one of the most baffling aspects of the eternal battle of the bulge: why we keep eating even when we’re full.
Short version: blame your brain.
When you’re hungry, food looks more appealing than when you’re not: hence the old adage about never shopping on an empty stomach.
Previous research has suggested that ghrelin, a hormone the body produces when it’s short of calories, may act on the brain to trigger this behavior. Now new research suggests that this ...

They shuffle along with blank faces and dead eyes, unseeing, unthinking, lost in some private hell that you as passerby can only pray never similarly engulfs you. You scuttle by, eyes averted, as though they have some horrible contagion against which neither face masks, Tamiflu nor vaccination can defend...and yet the odds are that for all your precautions, before Christmas arrives you will join their tormented ranks.
What’s that? Yes, zombies are big in pop culture right now, but what’s that go to do with...? Oh, I get it.
No, sorry, this column isn’t about zombies. It’s about husbands going shopping with their wives. It turns out there’s a solid scientific explanation for why women shop the way they do...and why men ...

The Saskatchewan Roughriders play the Calgary Stampeders in the Canadian Football League’s Western Final this Sunday.
That simple declarative sentence contains a novel’s worth of angst for fans of the Riders (and possibly for fans the Stampeders, too, but I can’t speak about that, not being one of those LOSERS!...oops, sorry, did I type that out loud?).
Roughrider fans, often said to be the greatest in the country, are passionate about their team. They want them to win. They really, really want them to win. (Please, God, let them win!)
And yet, deep down, they fully expect them to lose.
This, science tells us, is precisely why they enjoy watching the Riders play so much.
A new study from Ohio State University has found that ...

Why do we dream?
You’d think we’d know by now. Everyone dreams, and people have been fascinated by dreams throughout recorded history. But scientifically, their origin and importance remain uncertain. Do they serve some vital psychological or physiological function? Or are they just meaningless accidents of our brain’s wiring?
A few years ago, Finnish psychologist Antti Revonsuo theorized that dreams evolved as a way to rehearse threatening situations.
Silvio Scarone of the Universita degli Studi de Milano in Milan, Italy, explains it this way: “The environment in which the human brain evolved included frequent dangerous events that posed threats to human reproduction. These would have been a serious selection pressure on ancestral human populations and would have fully activated ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/10/Gelotophobia.mp3[/podcast]
It’s getting on toward Christmas, which means A Charlie Brown Christmas will soon be on TV...and we’ll once again get to watch Lucy give her nickel’s worth of psychiatric advice to Charlie Brown, listing all the phobias he could be subject to.
One she won’t list is gelotophobia, which, though it sounds like it means a fear of Italian ice cream (and, yes, everyone who writes about it makes that same joke), actually means a fear of being laughed at. More: those with gelotophobia find it difficult or impossible to distinguish between playful teasing and ridicule. To them, all laughter is aggressive. Not surprisingly, this can cause enormous problems in their social relationships.
Lots of other people don’t have a phobia, but ...

It’s probably happened to you. It’s certainly happened to me.
You’re at some social gathering or public event when someone says something so outrageously extreme that you can’t believe it.
The thrower of this verbal bombshell seems to assume everyone agrees with him...and since no one speaks up, except for a couple of people who express approval, you come to the conclusion that he’s right, that you’re the odd person out, and that, therefore, “This group is more left-wing/right-wing/certifiably insane than I thought!”
Take heart: you probably aren’t as out of step with the beliefs of others in the group as you think. The person making the extreme statements may think his views are in the majority...but he’s very likely wrong.
That’s the indication ...

When it comes to the brave new world of interpersonal communications via electronic networks, I believe I do quite well for a man who is...how can I put this delicately...no longer teenaged. Or twenty-something. Or thirty-something.
Or, as of this summer, even forty-something.
Despite my advancing years, however, I am still a with-it and happening dude. Not only do I, as you can see, have a firm grasp on the very latest hip-hop jive talk the young folks use, but I do all of the following, dear reader: Tweet, blog, podcast, Facebook, LiveJournal, and Flickr. (I used to MySpace, but I gave it up.)
I do not, however, chat, IM, or text.
It will come as no shock to anyone who has spent any ...

I had a hard time getting started on this column. See, as I was calling up the items I’d starred in Google Reader as possible topics, I thought it wouldn’t hurt to do a quick search for new reviews of my latest novel. And then I thought, well, as long as I’m online, maybe I’ll just skim through some blogs...and maybe check Facebook...and...
Well, you get the idea. Fact is, you’re lucky to be getting this column at all.
Which is ironic, because my jumping-off point is an article from Slate, written by Emily Yoffe, titled “
Seeking: How the brain hard-wires us to love Google, Twitter, and texting. And why that’s dangerous.”
There’s no doubt that the seeking out of information ...

“The itsy-bitsy spider went up the waterspout. Down came the rain, and washed the spider out...”
At which point a large percentage of us screamed and ran the other way, because surveys show that one fifth of men and a third of women are frightened of arachnids.
It makes sense, right? Spiders can be poisonous.
But so are stinging insects such as bees and wasps, and yet we seem to hate spiders more. At the University of Wurzburg, Germany,
psychologist Georg Alpers asked 76 students to rate photos of spiders, wasps, bees, beetles, butterflies and moths on how much fear and disgust they inspired and how dangerous they were. Spiders topped the list in all three categories—even though all bees can ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/08/Guilt.mp3[/podcast]
Guilt has gotten a bad reputation in recent years. People talk about being “plagued by guilt” as if guilt were some kind of mental illness.
But in fact, guilt is a very useful emotion. People who are entirely guilt-free have no constraints on their behavior. They can cheerfully commit all kinds of mayhem, from bullying to petty vandalism all the way up to rape, robbery and murder, and never feel a qualm: we call them sociopaths.
Guilt, then, plays an important role in keeping civilization civil. But where does it come from? And how does it interact with that other important civilizing mechanism that scientists call “effortful self-control”—the ability to suppress impulsive behavior that might hurt yourself or others?
New York Times science ...
