Breaking with tradition: The 'personal touch' is key to cultural preservation

Idiosyncratic acts performed during cultural practices are responsible for rituals' survival, says Tel Aviv University study

2014-11-24
(Press-News.org) "Memetics," or the study of memes, is a very popular discipline among cultural researchers now, particularly as it concerns new media like viral videos. But no one seems to know what a meme really is.

Originally coined by evolutionary biologist Richard Dawkins, the "meme" transfers cultural information much the way that genes inherit biological properties. Pharrell Williams' feel-good hit "Happy" (2013), one of the top-selling singles of all time, is a recent example of a wildly popular meme. Originally tucked away in the soundtrack of the film Despicable Me 2, the song spread across the viral Net through thousands of similarly-formatted cover videos, ultimately enjoying global sales of over ten million copies - a true display of memetic cultural transference.

However, unlike genes, well-defined biological entities with clear structural units, memes have long been slapped with the vague label "cultural replicators." Now a Tel Aviv University study scheduled for publication in the journal Neuroscience and Biobehavioral Reviews provides insight into the building blocks of cultural replication and the different ways they're used to preserve traditional rituals and practices.

Adding the personal touch to tradition

According to the research by Prof. David Eilam of the Department of Zoology at TAU's Faculty of Life Sciences, together with Dr. Michal Fux, Dr. Joel Mort, and Dr. Tom Lawson of Queens University Belfast, idiosyncratic acts, once considered merely incidental to the memes -- the common actions that form the basis of traditions -- are actually essential for their survival in a culture. Conducted alongside a few fixed memes, individualized gestures ensured the very survival of a ritual or practice by providing simplicity, flexibility, and creative license.

For the purpose of the study, Prof. Eilam and his team observed and analyzed a wedding dance called the "Umsindo," performed by the Zulu tribe in South Africa. In this dance, only one act -- the high kick, the standard meme of the dance -- was performed by all 19 participants. But all the dancers engaged in additional idiosyncratic movements resembling free-style dance before and after executing the high kick. The researchers found these idiosyncratic movements to be indispensable to the easy transference and preservation of this long-practiced cultural ritual.

Keeping it simple

"There are a limited number of common acts that lead to the continuation of any given tradition," said Prof. Eilam. "On the one hand this is surprising, but on the other it makes sense. You can't teach or transfer very complex things. In the Umsindo dance, there is just one common gesture. The rest you are free to improvise."

The same process characterized the application of phylacteries (a head and arm garment replete with leather bands and a small box) performed by observant Jewish men at the Tel Aviv University synagogue, the researchers observed. In the application ritual, only 11 out of 67 acts were recognized as common to all the gestures of the application and could be regarded as the "memes" by virtue of their commonality and high frequency of performance. Again, the vast majority of the gestures during the ritual were found to be idiosyncratic, providing flexibility and creative license during a rigorous religious ritual that has been practiced throughout centuries.

"The common acts of the memes are always accompanied by idiosyncratic acts that establish identity and preserve behavioral flexibility," said Prof. Eilam. "In other words, idiosyncratic acts, or 'behavioral variability,' appear to be an essential component that participates in the evolution of behavioral patterns, similar to genetic variability in biology."

Prof. Eilam is continuing his research on memes, exploring how these fixed actions emerge and why they are specifically selected in the evolution of cultural and other behavioral practices.

Teens prescribed anti-anxiety or sleep medications more likely to abuse those drugs illegally

2014-11-24
WASHINGTON - Teens prescribed anti-anxiety or sleep medications may be up to 12 times more likely to abuse those drugs illegally than teens who have never received a prescription, often by obtaining additional pills from friends or family members, according to new research published by the American Psychological Association. Based on surveys of more than 2,700 high school and middle school students from the Detroit area, almost 9 percent had been prescribed a potentially addictive benzodiazepine anti-anxiety medication (e.g., Xanax, Valium or Klonopin) or sleep medication ...

Sorting through recycling bins to learn about alcohol use

2014-11-24
COLUMBUS, Ohio - When researchers wanted to verify alcohol-use survey results at a senior housing center, they came up with a novel way to measure residents' drinking: Count the empty bottles in recycling bins. Scientists compared the recycling bin results with two residential surveys gauging drinking habits of people living in a San Diego complex for low-income, older adults. "We were able to check how much the residents said they were drinking with the empty beer, wine and liquor containers they were actually putting in the recycling bins," said John Clapp, co-author ...

Mimics do not substitute for the 'real thing' for bomb-sniffing dogs

2014-11-24
When it comes to teaching dogs how to sniff out explosives, there's nothing quite like the real thing to make sure they're trained right. That's the message from William Kranz, Nicholas Strange and John Goodpaster of Indiana University-Purdue University Indianapolis (IUPUI) in the US, after finding that dogs that are trained with so-called "pseudo-explosives" could not reliably sniff out real explosives (and vice versa). Their findings are published online in Springer's journal Analytical and Bioanalytical Chemistry. Genuine explosive materials are traditionally used ...

Experience with family verbal conflict as a child can help in stressful situations as an adult

2014-11-24
Washington, DC (November 26, 2014) - The holiday season gives people the opportunity to reconnect with friends and family each year. Sometimes these interactions can be stressful, especially around the Thanksgiving table where a heated debate can occur. How come some people are better at handling these stressful interactions than others? A recent study published in the journal Human Communication Research by researchers at Rollins College and The Pennsylvania State University found that individuals who were exposed to intense verbal aggression as children are able to handle ...

New volume documents the science at the legendary snowmastodon fossil site in Colorado

2014-11-24
DENVER--Nov. 24, 2014-- Four years ago, a bulldozer operator turned over some bones during construction at Ziegler Reservoir near Snowmass Village, Colorado. Scientists from the Denver Museum of Nature & Science were called to the scene and confirmed the bones were those of a juvenile Columbian mammoth, setting off a frenzy of excavation, scientific analysis, and international media attention. This dramatic and unexpected discovery culminates this month with the publication of the Snowmastodon Project Science Volume in the international journal Quaternary Research. Fourteen ...

An inside job: UC-designed nanoparticles infiltrate, kill cancer cells from within

2014-11-24
Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect (and potentially harm) nearby normal cells. In contrast to conventional cancer therapy, a University of Cincinnati team has developed several novel designs for iron-oxide based nanoparticles that detect, diagnose and destroy cancer cells using photo-thermal therapy (PTT). PTT uses the nanoparticles to focus light-induced heat energy only within the tumor, harming no adjacent normal cells. The results of the UC work will be presented at the ...

For important tumor-suppressing protein, context is key

2014-11-24
Scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have learned new details about how an important tumor-suppressing protein, called p53, binds to the human genome. As with many things in life, they found that context makes a big difference. The researchers mapped the places where p53 binds to the genome in a human cancer cell line. They compared this map to a previously obtained map of p53 binding sites in a normal human cell line. These binding patterns indicate how the protein mobilizes a network of genes that quell tumor ...

"Importantly, ...

Protein that rouses the brain from sleep may be target for Alzheimer's prevention

Protein that rouses the brain from sleep may be target for Alzheimers prevention
2014-11-24
A protein that stimulates the brain to awaken from sleep may be a target for preventing Alzheimer's disease, a study by researchers at Washington University School of Medicine in St. Louis suggests. In recent years, scientists at Washington University have established links between sleep problems and Alzheimer's. For example, they have shown in people and in mice that sleep loss contributes to the growth of brain plaques characteristic of Alzheimer's, and increases the risk of dementia. The new research, in mice, demonstrates that eliminating that protein - called orexin ...
