The Language of Culture

Culture is central to human success?  Well, that is exactly what author and evolutionary biologist Dr. Mark Pagel suggests in his new book Wired for Culture.

The Wall Street Journal is reporting that the thesis of Dr. Pagel’s book is that human being’s lives became dominated by culture, they could have adopted habits that did not lead to having more descendants.  However,  we did not.  We set about using culture to favor survival of those like us at the expense of other groups.

In this book, Pagel argues that, “[if our] cultures have promoted our genetic interests throughout our history,” then our “particular culture is not for us, but for our genes.”

He delineates the connection between different languages and diverging cultures.  He calls language “one of the most powerful, dangerous and subversive traits that natural selection has ever devised.”

Do you agree with that statement?

In his book, Pagel goes on to extrapolate that the parallels between genetics and linguistics are that they are both digital systems, in which words or base pairs are recombined to make an infinite possibility of messages.

He writes, “ People will risk their health and well-being, their chances to have children, or even their lives for their culture.  People will treat others well or badly merely as an accident of their cultural inheritance.”

Think about the actions and cultures of other nations.  Do you agree with that statement?

Disgust & Disease

Can the emotion of disgust help us stay healthy?

Recent articles from Metro.com (uk) and SF Gate suggests that it very well can.

It is scientifically proven that disgust is one of the seven basic universal facial expressions of emotion, meaning it is expressed in the same manner, on the face, across cultures.

Metro reports that researchers, from the London School of Hygiene and Tropical Medicine, say that disgust is a major factor in the survival of our species.

“Imagine a world without disgust.  Can you imagine how awful it would be?  You’d be treading through poo every day, there’d be food piled up and rats eating waste in the streets… we would be extinct very quickly, ” affirms Dr. Valerie Curtis lead researcher.

Dr. Curtis believes disgust is a powerful way to help people change their behavior and points out that 40% of the world has bad sanitation.  The research of Dr. Curtis and her colleagues aims to explore disgust and harness its “power” to improve our lives by curbing the spread of disease.

Past research on disgust has shown that different areas of the brain experience an increase in activity when disgusted by something.  Other species use disgust as a survival mechanism as well.  Fish avoid other fish that have parasites and mice won’t mate with other mice that are sick.

Disgust has evolved to be about survival.  It also impacts the behaviors that humans choose to make and is categorized as a  negative emotion but it has both positive and negative effects.

Dr. Matsumoto talks about the effects of disgust in his research article Emotion in Predicting Violence published in the January 2012 issue of the FBI Bulletin.

He points out that when comparing emotions such as anger, contempt and disgust, all, perhaps, negative in terms of valence, it is important to know that differences among these emotions clearly show that they are not alike.  Anger, contempt, and disgust have different physiologies, mental states, and nonverbal expressions.

He goes on to state, “disgust causes an individual to eliminate or reject contaminated objects…anger focuses on persons’ or groups’ actions, while contempt and disgust focus on who they are.

Eye Movement Mishaps

LP Magazine has reported on the misconceptions between eye movement and deception detection.  They refer to a seminar by Humintell’s director Dr. Matsumoto at the Certified Forensic Interviewer Elite Training Day last November.

The seminar focused on the difficulty in establishing deception or truth and the flaws most people commit when trying to do so.  After reviewing a number of videos, participants were asked to judge whether the person on the video was  being truthful or deceptive and why they were identifying that person as truthful or deceptive.

No surprise to Dr. Matsumoto, many of the participants delineated eye contact (lack of or too much) as a sign of deception and pointed out that the suspect looked left or right as they were being questioned.

It is particularly difficult to define statements of truth when there is no norm (baseline) to observe, no real threat of punishment if caught lying, or no strong emotion to conceal (high stakes situations). Dr. Matsumoto was quick to note that twenty-three of twenty-four research studies finding’s had no support for eye direction as an indicator of truth or deception.

The article goes on to discuss the role of Neuro-Linguistic Programming (NLP) and Recall vs. Creation in the process of predicting truthful vs. deceptive statements.

It points out that eye movements assist in the recovery of memories and speech and establishes that there is a memory search and additional thought taking place. This additional thought could either be of a creative or recall nature.

However, there is no way to establish whether this is the recovery of a truthful detail or the creation of a deceptive component of the story.

Did you have these same misconceptions?  Do you agree with this article?
