The OTHER Foreign Accent Syndrome : I do not understand nor believe you !

YouTube Preview Image

As shown in the video above, humans love to imitate accents from around the world. Studies from the University of Manchester  believe that  if you talked to someone in their accent, you would understand  them better. Our brain is  an accent discriminator and tends to doubt foreign accents.The moment we hear an accent we diagnose the person as foreign and unfamiliar.

An accent is defined as a  distinctive way of pronunciation, inflections, tones and emphasis patterns. In 2010, University of Chicago psychologists Shiri Lev-Ari and Boaz Keysar studied how the brain processes non-native accents in a report entitled ” Why don’t we believe non-native speakers?:The influence of accent on credibility”. This would prove that our brain doubts foreign accents therefore the credibility of one’s words is lost behind one’s accent. People were asked to judge the truthfulness of trivia statements received from either native and non native English speakers. Lev-Ari and Keysar hypothesized that if the subject found the statement less believable when the messenger had an accent then credibility  was associated to the ease of processing the speech known as cognitive fluency.

Experiment 2 : Truth ratings as a function of accent by Lev Ari and Keysar

In the second part of the experiment, Lev-Ari and Keysar tested if the doubt would be observed if subjects were aware that they were doubting foreign
accents. Therefore, this time, the psychologists informed the participants about  the purpose of their study on cognitive fluency and credibility. Nonetheless, the same conclusions were observed in which statements were less believed when the messenger had a heavy accent. The psychologists suggested that instead of perceiving their speech as harder to understand, it was thought as less truthful.

This research was then compared to  the University of Michigan ‘s study on the impact of a decreased font size when asking subjects :  “How many animals of each kind did Moses take on the Ark?” [Answer: None – Moses wasn’t on the Ark, Noah was].  Font size like accents decreases cognitive fluency.Researchers now go on to say that one should practice analyzing small fonts more carefully and do likewise with non-native accents.

However, Pavel Trofimovich, applied linguist at Concordia University, believes that one should listen beyond the accent and judge credibility with grammar and vocabulary, hence, comprehensibility. Similarly, his British colleague, Talia Isaacs highlights the importance of identifying aspects of speech that don’t actually affects listener’s understanding  but enhance stereotypes. Upon researching about accents, it is easy to come across these stereotypes with imitations.

Ultimately , we should be aware of both accents and comprehensibility.Imitation  may help to adapt to one’s  accent. However, there is a risk of falling into offensive stereotypes . Similarly, one must be aware and parse the brain’s discrimination towards unfamiliar and foreign accents.   Therefore, refocus on judging the messenger’s credibility with both their actions and words not just their accents.

From Toy Soldiers to Convicted Criminals

What if someone told you that if  lead is found present in your bones, you are more likely to be a delinquent? In 2007, you may have encountered a report or read an article on lead poisoning due to lead containing toy products and households.

Following such reports, the general public understood the effects of lead poisoning as a toxin. In 1996,USA had banned the use of the element as an additive to gasoline. However, minimal amounts of lead were still used  in the production of batteries, jewelry,toys and paint products. After the 2007  Mattel recall , customers around the world looked carefully at the lead label when purchasing house and toy products. In 2008, Henry Clement, Canadian Health Minister, announced that the government would increase the number of inspections with an increase in a maximum fine of $5 million if high levels of lead were detected in children’s jewelry and other products.

The public and government then understood  that lead has a dangerous effect whether a child was breathing or swallowing it. Children exposed to high levels of lead can suffer from kidney and brain damages. While low levels of exposure is a health hazard to all.This knowledge resulted in lead safety campaigns and sites such as www.leadfreekids.org. , which offers support and advice about lead inspections and protection techniques. In 2010, the federal government  decided to effectively ban lead from toys for children and other home products.Health hazards such  as kidney damage, brain damage,  hyperactivity, headaches,hearing problems could be prevented with precautions.However, lead exposure could result in more than these physical health problems but behavioural problems such as delinquency.

More studies have now been developed on lead poisoning. In 2013, Summer Miller pointed out data from US Centre for Disease (CDC) and suggested that high levels of lead exposure lead to juvenile delinquency. They have now diagnosed that 10 micrograms per deciliter of lead can cause lead poisoning. Subsequently, this small amount of lead can be identified with signs of headaches and abdominal pains. As informed in 2007, lead exposure impacts the human brain.Miller states that studies now find higher levels of lead in delinquents and how it affects their intelligence, communication skills and behaviour.

This was observed in a 2000 study  in Allegheny County. It concluded that 216 youths in a Juvenile Court had a higher high bone-lead level in comparison to 201 non-delinquents control in a Pittsburgh high school. Children with cognitive and behaviour problems are more likely to have higher blood concentrations due to lead exposure.

Sometimes it is not just about what children swallow or touch or symptoms we physically see, sometimes just that exposure can change the way things play out.

300 million year old plants for sale: $100,000 !!!

Imagine having survived mass extinctions dating back to 300 million years ago and now becoming extinct in 2013. This is the story of cycads, the oldest seed plants. They resemble a combination between a fern and a prehistoric palm. Their ancient characteristics have given significant insights to scientists about the origin of plant species. Unfortunately,today,these plants  have become a valuable prey  to poachers, similar to other endangered animals around the world. Cycads are now on the global conservation agenda as their preservation is key to  the development of plant biology.

Cycads from Flicker by Steve Williams

Cycads have helped determine the age of flowering plants. For example, experimenters hypothesized that  the reproductive structure of the cycads were wind pollinated. Subsequently,  they compared several other cycads and concluded that most species were actually insect pollinated by beetles. Thus insect pollination is much older than the wind pollination of flowering plants. Without the discovery of these seed plants, the maturity of insect pollination would not have been determined.

Luckily their decline has now come to the attention of scientists. Philip Rousseau, a botany researcher at the University of Johannesburg, fears that wild cycads could become extinct.  As shown on the map, South Africa is  one of the many regions with a high distribution of cycads but now 31 percent of the species are disappearing. The current poaching rate could make them extinct in the wild by next year.  Poachers have found malicious ways to find the plant by hunting at night and selling them during the day. Each tree can be sold for as much as  $100,000 to various collectors in the black market. Farmers and landowners have called for bans and regulations for cycads before it gets out of control and existence.

Funding boost for DNA barcoding in South Africa

In order to regulate and preserve the cycads, the University of Johannesburg funded a scientific project in which they identified rare species using a DNA barcoding  system. Researchers would take less than 1 gram of the plant’s DNA, crush it, treat it with chemicals and record its barcode. This would allow custom officials to check smugglers with a device reading the plant’s DNA. Lastly, the project would help the University of Guelph complete their International Bar Code of Life Project. Once again, the cycads would help determine the earth’s biodiversity.

The prehistoric age of Cycads is very valuable to science.  However, it  is now a valuable commodity to poachers like ivory or rhino horns. For this reason, a conservation plan is important to protect one of the key species to the history of plants. For sale or for history?
