The Omnivore’s Dilemma

9 Jul

Reading The Omnivore’s Dilemma by Michael Pollan. I’m a few years behind with picking this one up, but I’m pleased so far with its much-needed presentation of a very current issue — our [American] national eating disorder.

Let’s face it–Americans are obsessed with diet. Between the Atkins craze, Paleo fanatics, and organic junkies, many of us just don’t know where to turn. Even the people I know personally around here seem to be baffled by what’s referred to as the “French Paradox”: people from other cultures seem to eat whatever fat-dripping, butter-sopping foods they please, and somehow manage to stay, on the whole, a heck of a lot skinnier than we do. Pollan introduces the “American Paradox”: “a notably unhealthy people obsessed by the idea of eating healthy.”

So what’s going on with us? Why are we so much bigger and unhealthier? Many theories are out there. I’ll see what Pollan has to say past the first two chapters. So far, this book’s looking like a good’un.

RI (MA) gems – 2

Ok, so… I know this one isn’t technically from Rhode Island, but I’ve always basically put Massachusetts in the same category. Here are some pictures of us cruisin’ along South Beach in Martha’s Vineyard. Gorgeous. 

RI Gems – 1

8 Jul

Since I’m extremely broke and about to take out an ENORMOUS graduate student loan, I’m pinching pennies this summer. This means I’m stuck at home in Rhode Island until August.

With many of my good friends having already shipped off to various ends of the earth for wonderful summer adventures/internships/projects/important stuff, I’ve decided to chronicle my time – *yawn* – back home. My hope is that I’ll stumble across some gems in RI that I never really took the time to notice while growing up here.

One aspect I’ve enjoyed so far: cycling around the state. I didn’t really become an avid cyclist until after I went off to college, so I never actually got a chance to check out the routes around town in RI.

    Here’s a little glimpse of cycling around Block Island – a magnificently pristine chunk of land about 13 miles off the mainland RI coast. It was recently deemed by The Nature Conservancy as one of the “Last Great Places on Earth”. Bikes are allowed on the ferry for $6, and it’s definitely worth it – cycling is the best way to get around this place. The terrain was actually a bit hillier than I anticipated, so I was only able to snap some good pictures while riding near the coastline.

The draw of Block Island for me is its untouched quality. Granted, there’s not much to “do” there; many of my family members dislike going because of the lack of classic attractions. I’m perfectly fine with riding around, stopping at the beach, and getting some ice cream at Block Island’s original homemade ice cream parlor. (I’m drooling just thinking about the heaping pile of maple walnut ice cream I devoured.)

I was relieved to find that drivers on the island knew how to treat cyclists–they’re used to them. Unfortunately, this is not the case back on the mainland, where I’ve had all sorts of vehicles just absolutely baffled by me minding my own business in the shoulder — honking, slowing to my speed and riding my tail end, yelling out the window — you name it, it’s happened. Rhode Islanders, please get on the bicycle wagon. There are a lot of us. Get used to it.

Anyway, despite the mainland drawbacks, I’ll be touring more parts of the state by bicycle in hopes of coming across scenes like this one. Block Island is a definite gem.

The Religious Impulse (Final A.M. Tidbit!)

25 Oct

I found my favorite chapter in The Accidental Mind.

Chapter 8, “The Religious Impulse”, is Dr. Linden’s theory/explanation of one of my favorite topics: Religion. Religion is omnipresent on this planet, in one form or another: one God, multiple Gods, spirits, versions of world creation, visions of afterlife… every culture has religion. But why?

Through a series of experiments, Dr. Linden describes the mind’s uncanny ability to create a “gap-free narrative” of our experiences — a seamless amass of consecutive perception. He draws from Roger Sperry’s fascinating studies of split-brain patients as well as from studies of patients with anterograde amnesia. I’ll let his descriptions of these experiments do the talking for me, but I’ll introduce the concept with an easier example first.

When we look around with our eyes, the images our brain creates seem continuous; however, our eyes are not actually perceiving things continuously at all. Our eyes move in jerky motions — called saccades — and do not gather light reflection in the ‘in-between’ steps (the motions themselves). Yet the brain forms an image of the world without any gaps. It seems it does the same thing when confronted with more complex, higher-order cognitive problems. Dr. Linden uses split-brain patients to demonstrate this, focusing on the lack of communication between the right and left hemispheres and the resulting story-making:

“Split-brain patients provide a unique opportunity to see how the left and right cortices process information independently. In one famous experiment, a split-brain patient was placed before a specially constructed screen, designed so that the left cortex received only an image of a chicken’s claw (projected in the right visual field: the representation of the visual field is reversed right to left in the brain) while the right cortex saw a winter landscape with snow. When asked to pick a card with an image to match, the right cortex, which controls the left hand, picked a shovel to go with the theme of snow, while the left cortex, which controls the right hand, picked an image of a chicken to go with the claw. This shows that each side of thecortex could recognize its image and make an appropriate association. When the patient was asked why he chose those two images, the response came from the left side (that is the only one that can speak–theright is mute); the response was, “Oh, that’s simple. The chicken claw goes with the chicken and you need a shovel to clean out the chicken shed.”

Let’s think carefully about what’s happening here. The left brain saw the chicken claw but not the snow scene. When faced with the shovel and the chicken it retroactively constructed a story to make these disparate choices appear to make sense. Michael Gazzaniga, in his book entitled The Mind’s Past, from which this example is taken, notes, “What is amazing here is that the left hemisphere is perfectly capable of saying something like, “look, I have no idea why I picked the shovel… Quit asking me this stupid question.” Yet it doesn’t.”

This call to narration, he suggests, may serve as a neural basis for forms of religious belief. Here it is in his own words:

“I suggest that the left cortex’s always-on narrative-constructing function promotes the acquisition of religious thought through both subconscious and conscious means. Religious ideas largely involve nonnaturalistic explanations. Whether religious ideas are regarded by their practitioners as “faith” or merely “given knowledge”, they share the property that they violate everyday perceptual and cognitive structures and categories. The left cortex predisposes us to create narratives from fragments of perception and memory. Religious ideas are similarly formed by transforming everyday perceptions, by building coherent narratives that bridge otherwise disparate concepts and entities. Pascal Boyer proposes that the most effective religious concepts preserve all the relevant inference os a particular cognitive category except those that are specifically prohibited by a special nonnaturalistic aspect.”

He ends the chapter with this statement: “Our brains have evolved to make us believers.”

While I think this curious tendency towards making ‘stories’ out of our perceived reality has some other interesting implications, applying it to religion seems to fit rather well. Unfortunately, like Dr. Linden, I have been feeling a bit hesitant to try and explain this idea to people with strong religious beliefs. I myself believe that the idea can fit well with strong believers — nothing says that ‘God’ didn’t intend for our brains to be constructed such that believing would be so natural — but others may spin the theory with science as the victor, removing the mystery and awe that should be attributed to a “leap of faith”. Hm.

This has prompted me to go out searching for more. I’ve picked up Why Would Anyone Believe in God? by Dr. Justin Barrett at Oxford — more explanation from the cognitive science perspective. I’ll keep you updated. :)
