Food Fight: Taxing Unhealthy Foods May Encourage Healthier Eating Habits
Recently, the Obama administration called for a total ban on candy and soda in the nation’s schools. States are beginning to impose “sin taxes” on fat and sugar to dissuade people from eating junk food. Pricing strategies may well be a key to changing behavior, but others favor subsidies over punitive taxes, as a way to encourage people to eat fruits and vegetables and whole grains. The thought is that if you make it cheaper, people will eat more of it, more expensive and people will eat less.

The Mind of a Misanthrope
I become misanthropic every February. I avoid social gatherings, and really just want to hole up at home. I always assumed it was the dark evenings and slippery sidewalks and general misery of venturing outside. But truth be told, I don’t want guests visiting me either. Not until the crocuses come through. Or not until cold and flu season is over, more accurately. New research suggests that my anti-social ways may have little to do with friendliness or lack of it. Indeed, my attitudes and actions may be self-protective, part of an ancient, hard-wired psychological immune system, shaped over eons to help humans steer clear of germs. Think of it from an evolutionary point of view.

The Science of Hollywood Blockbusters
There is something about the rhythm and texture of early cinema that has a very different “feel” than modern films. But it’s hard to put one’s finger on just what that something is. New research may help explain this elusive quality. Cognitive psychologist (and film buff) James Cutting of Cornell University, along with his students Jordan DeLong and Christine Nothelfer, decided to use the sophisticated tools of modern perception research to deconstruct 70 years of film, shot by shot. They measured the duration of every shot in every scene of 150 of the most popular films released from 1935 to 2005. The films represented five major genres—action, adventure, animation, comedy and drama.

Focusing on the Cinematic Mind
Our household is a rolling Alfred Hitchcock festival. We almost always have at least one of the celebrated director’s films on DVD, and over the years we have watched most of our favorites—Suspicion, North by Northwest, The 39 Steps—time and time again. It’s a tribute to the master’s skills and sensibility that his films have such enduring appeal, because many films from the same time period have a distinctly “old” feel to them. It’s not just the primitive cameras and films. There is something about the rhythm and texture of early cinema that has a very different “feel” than modern films. But it’s hard to put one’s finger on just what that something is.

A Salvo in the Calorie War
The calorie war is heating up. It’s actually been simmering for some time, sparked by an alarming obesity rate among young Americans and related spikes in diabetes and other health problems. Nobody really disputes this sorry trend anymore, but there is a lot of disagreement over what to do about it. Public health advocates are clamoring for everything from warning labels on junk food to aggressive television marketing campaigns, even for outright prohibitions. Just last week, the Obama administration entered the fray, calling for a total ban on candy and soda in the nation’s schools. Some see the past tobacco war as the proper model for this public health campaign.

Bilingual Babies: The Roots of Bilingualism in Newborns
It may not be obvious, but hearing two languages regularly during pregnancy puts infants on the road to bilingualism by birth. According to new findings in Psychological Science, a journal of the Association for Psychological Science, infants born to bilingual mothers (who spoke both languages regularly during pregnancy) exhibit different language preferences than infants born to mothers speaking only one language. Psychological scientists Krista Byers-Heinlein and Janet F. Werker from the University of British Columbia along with Tracey Burns of the Organization for Economic Co-operation and Development in France wanted to investigate language preference and discrimination in newborns.
