The Tongue Map Myth

Many of my students are shocked to read in their psychology textbooks that the "Tongue Map" is somewhat of a myth, particularly because even some of their current science textbooks continue to print this misinformation. For the skeptical, here are some links to credible information on the subject:

• The Tongue Map: Tasteless Myth Debunked (from livescience.com)
• The Tongue Map: An Enduring Myth - introduces a more accurate diagram
• Tongue Myths Debunked; Frustrated Gradeschoolers Vindicated
• Really? The Claim: Tongue is Mapped Into Four Areas of Taste - NY Times Article
• I hate to mention this, but even Wikipedia doesn't buy the Tongue Map Myth

I'd have to agree with Christopher Wanjek, writer for Livescience.com's Bad Science Column:

"The degree of variation is still debated, but the kindest way to describe the tongue map is an oversimplification. Why textbooks continue to print the tongue map is the real mystery now."

Phantom Limbs

Today during our class discussions on sensation, a number of questions came up for which I had no readily available answers. The links I've put together below are an attempt to answer some of these questions.

1. Many of my students had questions about Phantom Limbs. This is a condition wherein an amputee still "feels" sensations from the missing limb (pain or otherwise). The tricky part about answering questions that relate to phantom limbs is that so much of the research is gleaned from case studies...so the question, "Would someone with a phantom limb feel ______________?" is hard to answer. It may be true of some patients, but not others. Or we might not have documentation of that specific situation within known case studies (but that doesn't mean it doesn't exist). The Psychology Department at Macalester College has a good site for further investigation. It provides a bunch of information on phantom limb patients, and examples of case studies on the phenomenon.
2. One interesting treatment for Phantom Limb Pain is the use of Mirror Boxes. Below you will find a video featuring Andrew Austin (a treatment provider from the UK) describing the use of Mirror Boxes in therapy. If you have a bit longer, you can check out a 2007 TED Talk by VS Ramachandran which describes the use of mirror boxes to successfully treat phantom pain (as well as two other types of disorders resulting from physical damage to the body).

Why You Should Come to Psych Club this Friday: The Dragon Illusion!

Here's what we're doing in Psych Club this Friday (during Lunch B): making cool dragon optical illusions! Check out the final version:

Hearing, The Ear & Georg Bekesy

Today in class you will be exploring The Ear Pages, a site dedicated to Nobel Prize winner Georg Bekesy and his discoveries about the ability of the human ear to detect frequency (in sound waves).

When you finish, there are number of sites you might choose to explore, including some of the ones I have shown you in class over the past few days. The sound illusions work best with headphones.

• Holophonic Sound (sound illusion)
• Five Great Auditory Illusions
• The Counter-Rotating Spiral (motion afterimage)
• A Gallery of Visual Illusions (particularly good because the explanations are included)
• Another Blind Spot Locator
• Subjective (a.k.a. "illusory") Contours

Reverse Speech and Backmasking

Today in class I shared with students several examples of supposed "reverse speech" and "backmasking" in popular songs during a lecture on subliminal sensation. Here are the websites for your own entertainment/explorations:

T-Shirts Have Been Ordered!

It's about time!

I've given up on those stragglers who have not paid for the shirts they signed up for. If you had payment in for your shirt as of today, you can expect to get one. If not, well....you snooze you lose.

The order is scheduled to come in by November 20th, which (conveniently) happens to be the date of our next Psych Club meeting! Oh boy! I can hardly wait to see us all decked out in our finest Freud-wear.

Time to Chat with Mrs. Welle

Although it's hard to believe it, we're approaching the end of the first quarter here at Chi-Hi. This makes it a good time to reflect on how things are going so far, and where we are headed this year.

To that end, for the first time this year I am requiring that students meet with me one-on-one for a 10-minute conference. I find, with so many of you (84!), I am having a hard time getting to know everyone individually and I want to make sure we're both doing everything we can to make sure you have a successful year. Basically, we'll just chat about how things are going in AP Psych.

In my room, you'll find a sign-up for available conference times. All time slots listed are during our Lunch & Learn time, though other arrangements may be possible. Given that I have so many to arrange and can only complete about 5 per lunch period (or less, if I have other scheduled meetings), my goal is to get done with all of these by the end of November.

Completing the Pre-Conference Worksheet and attending your scheduled conference will be worth a 10-point project grade (for 2nd quarter). Please make every effort to attend at your scheduled time, as spaces will fill up fast!
